Description

This low voltage NPN transistor has been designed for applications requiring high gain and very low saturation voltage. The SOT23F package is pin compatible with the industry standard SOT23 footprint but offers lower profile and higher dissipation for applications where power density is of utmost importance.

Application(s)

Boost converters

Lamp and relay driver

Siren driver

MOSFET and IGBT gate driving

Motor drive
