NPN EPITAXIAL SILICON
DARLINGTON TRANSISTOR
DESCRIPTION
The UTC TIP112 is designed for such applications as: DC/DC
converters supply line switching, battery charger, LCD backlighting,
peripheral drivers, Driver in low supply voltage applications (e.g.
lamps and LEDs) and inductive load driver (e.g. relays, buzzers and
motors).
FEATURES
* High DC current gain : hFE = 1000 @ VCE =4V, IC=1A (Min)
* Low collector-emitter saturation voltage
