2SA1646,2SA1646-Z

Silicon Power Transistor

Description

The 2SA1646 is a mold power transistor developed for high-speed switching and features a very low collector-to-

emitter saturation voltage. This transistor is ideal for use in switching power supplies, DC/DC converters, motor drivers,

solenoid drivers, and other low-voltage power supply devices, as well as for high-current switching.

Features

• Fast switching speed

• Low collector-to-emitter saturation voltage:
