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.
