Description

These N-Channel enhancement mode field effect transistors are produced using Diodes Incorporated’s proprietary, high density and advanced trench technology. These products have been designed to minimize on-state resistance while providing rugged, reliable and fast switching performance. These products are particularly suited for low-voltage, low-current applications such as: small servo motor controls, power MOSFET gate drivers, and switching applications.

Feature(s)

Low Gate Threshold Voltage
Low Input Capacitance
Fast Switching Speed
Low Input/Output Leakage
High Drain-Source Voltage Rating
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
This part is qualified to JEDEC standards (as references in AEC-Q) for High Reliability. https://www.diodes.com/quality/product-definitions/
An automotive-compliant part is available under separate datasheet (BSS123Q)

Application(s)

Small servo motor controls
Power MOSFET gate drivers
Switching applications
