Low Vcesat NPN Epitaxial Planar Transistor
Spec. No. : C820I3 Issued Date : 2004.12.19 Revised Date :2005.07.26 Page No. : 1/ 4
BTD1805I3
Description
The device is manufactured in NPN planar technology by using a "Base Island" layout. The resulting transistor shows exceptional high gain performance coupled with very low saturation voltage.
Features
* Very low collector-to-emitter saturation voltage * Fast switching speed * High current gain characteristic * Large current capability
Applications
* CCFL drivers * Voltage regulators * Relay drivers * High efficiency low voltage switching applications
