General Description
This Power MOSFET is produced using SemiWell’s advanced
planar stripe, DMOS technology. This latest technology has been
especially designed to minimize on-state resistance, have a low
gate charge with superior switching performance, and rugged
avalanche characteristics. This Power MOSFET is well suited
for synchronous DC-DC Converters and Power Management in
portable and battery operated products.
