STD2805
Low voltage fast-switching PNP power transistor
Preliminary Data
Features
■ Very low collector to emitter saturation voltage
■ High current gain characteristic
■ Fast-switching speed
■ Surface-mounting DPAK (TO-252) power
package in tape & reel (suffix “T4)
■ Through-hole IPAK (TO-251) power package
in tube (suffix “-1”)
Description
The device is manufactured in PNP Planar
technology by using a “Base Island” layout. The
resulting transistor shows exceptional high gain
performance coupled with very low saturation
voltage.
