This is one of the types of MOSFETs and is a kind of transistor.
Part Number: D4454, AOD4454
Function: 150V, 20A, N-Channel MOSFET
Manufacturer: Alpha and Omega Semiconductor
Package: TO 252 Type
This is 150V, 20A, N-Channel MOSFET.
The D4454 combines advanced trench MOSFET technology with a low resistance package to provide extremely low RDS(ON). This device is ideal for boost converters and synchronous rectifiers for consumer, telecom, industrial power supplies and LED backlighting.
