SILICON POWER TRANSISTOR
2SA1645, 2SA1645-Z
PNP SILICON EPITAXIAL TRANSISTOR FOR HIGH-SPEED SWITCHING
The 2SA1645 is a mold power transistor developed for highspeed 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 highcurrent switching.
FEATURES • Fast switching speed • Low collector-to-emitter saturation
