STD2805
STD2805 is Low voltage fast-switching PNP power transistor manufactured by STMicroelectronics.
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.
