8N50H
8A, 500V N-CHANNEL
POWER MOSFET
DESCRIPTION
The UTC
8N50H
is an N-channel mode power MOSFET using
UTC’s advanced technology to provide customers with planar stripe
and DMOS technology. This technology allows a minimum on-state
resistance and superior switching performance. It also can withstand
high energy pulse in the avalanche and commutation mode.
The UTC
8N50H
is generally applied in high efficiency switch
mode power supplies, active power factor correction and electronic
lamp ballasts based on half bridge topology.

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Drain current limited by maximum junction temperature
3. Repetitive Rating: Pulse width limited by maximum junction temperature
