Green and Lead Free Product Information and Issues

Diodes Incorporated Is Committed to a Global Green Environment

Eliminating lead from pin/terminal plating was the first step towards “Green” products. Diodes is taking additional steps to remove halogens and antimony compounds and will announce each change with the appropriate mechanism: i.e., New Product Announcement or Product Change Notice (PCN). We strive to continuously reduce the environmental impacts of our products and meet the demands of our customers for such. Material Content Lists are available. Please request this through your Sales Representative or email compliance@diodes.com.

Diodes Incorporated's Lead-free / Green Policy

Diodes defines "Green" products as those which are RoHS compliant and contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br+Cl) and <1000ppm antimony compounds.

Lead Free (Pb-Free) / Green Information at a Glance
  1. Diodes’ definition of “Lead Free."

Diodes, Inc.’s products defined as “Lead Free” will contain no purposefully added Lead either internally or externally. Only trace elements may remain.

  2. Diodes’ definition of products with a “Lead Free Finish.”

These products will have no external Lead, but will still contain internal Lead in the form of high temperature die bonding solder, glass encapsulation or glass die passivation. Lead in these types of materials are currently RoHS exempt.

  3. Diodes’ definition of “Green”.

Diodes defines "Green" products as those which are RoHS compliant and contain <900ppm bromine, <900ppm chlorine (<1500ppm total <900ppm chlorine (<1500ppm total Br+Cl) and <1000ppm antimony compounds ) and <1000ppm antimony compounds.

  4. Diodes is committed to environmental friendliness.

Please request this through your Sales Representative or email compliance@diodes.com.

  5. Diodes' Road Map for Green and where products are manufactured.

In 2006, Diodes eliminated most SnPb plated versions of products. In addition, more and more products were introduced in a “Green” format. Diodes, Inc.’s Green products do not contain Halogens or Sb compounds.

Over time, as demand warrants, the traditional non-green products will be discontinued. This will be announced by a Product Change Notice (PCN). Demand will affect which packages are discontinued first.

Finished products are manufactured in the Republic of China, Europe, Malaysia and Taiwan.

   6. Lead Free or Green options may not be offered for 100% of Diodes' products.

Conversion will be governed by demand.

  7. Products with the new lead free finishes can be used with Pb containing solders.

The lead-free solder finishes are backwards compatible with Pb-containing solders. Soldering profiles may need to be adjusted slightly depending on the many design and usage variables.

  8. Removal of halogens and antimony compounds.

Removal of halogens and antimony compounds is brought about by a change of molding compounds only. No electrical or performance changes are made for this conversion. All these ratings remain the same.

  9. There will be no specification changes other than to reflect the Lead Finish and Molding Compound.

No, there will not be any specification changes other than to reflect the Lead Finish and Molding Compound. Products will continue to be qualified to 260°C solder re-flow profiles. Moisture Sensitivity Level (MSL) will remain unchanged unless specifically announced otherwise on an individual product. Reliability and Qualification Testing will remain as is before with the exception of additional Solderability Testing using Pb Free solders. No major changes should be necessary in customer's processes except for solder profile adjustments.

  10. Details on product availability.

Products with SnPb solder finishes are no longer available.

  11. Prices may change.

There are many variables that impact pricing. While we have experienced a slight manufacturing cost increase for Green product versions, we do not anticipate any immediate change of pricing because of these changes.

  12. Part Numbers changes.

Over the last few years there have been some changes to part numbers to distinguish RoHS and “green” versions of our products. Please refer to the data sheets for specific product ordering information and to determine the green conversion status.

  13. Buying product with the old SnPb Lead Finish after the conversion date.

Products with SnPb solder finishes are no longer available.

Green molding compound changes are by date code. Once stock is exhausted, the device will not be available with the old compound.

  14. How to distinguish between Finishes on the product.

Product package labeling clearly states the status of the parts. Please see Document AP02006.pdf for complete labeling information.

The sheen of Matte Tin vs. SnPb Finish is visibly different. It is not possible to tell Green from non-Green products once put into use.

  15. Testing done to qualify Lead Free Finishes for use in standard SMT/Through-hole assembly processes.

Each product family where the Lead Finish is being converted to Pb Free has been or will be re-qualified by subjecting a family sample to the following tests (typical):

Preconditioning (PC) followed by:

Highly Accelerated Stress Testing (HAST)
Autoclave (AC)
Temperature Cycling (TC)

Solderability

With SnCuAg Solder
With SnPb Solder

Resistance to Solder Heat (RSH)

  16. Please refer to Data Sheets for change indications.

Data Sheets will contain ordering information for each version of a component where more than one version is available. Also, the Features Section will indicate when a Lead Free Version of a product is available or if a product is Lead Free by design, and it is Green. The Mechanical Data Section will have a notation regarding the type of Lead Finish plating.

What is RoHS?

RoHS stands for Restriction of use of Hazardous Substances.

RoHS was a directive issued January 27, 2003 by the European Commission (EC) and recast on June 8, 2011. It sets maximum limits on certain chemical elements and substances which can be present in electronic equipment "put on the market" throughout the European Union.

RoHS is part of a growing wave of environmental regulations on green initiatives. In addition to RoHS for Europe, there are similar regulations in China and other Asian nations. Japanese companies have created a non-governmental group to standardize green procurement requirements. In the US, individual states are passing laws restricting some substances and requiring recycling of certain classes of products. A common theme is the so-called "take-back" feature that requires manufacturers to accept old products from consumers and reuse or recycle the items.
