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 voltage:
VCE(sat) = −0.3 V MAX. @IC = −4 A
