Preliminary Data Sheet
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:
