IXFH46N30T Equivalent & Substitute Parts Reference

Part Overview

The IXYS IXFH46N30T is an N-Channel MOSFET rated for 300 V and 46A continuous drain current (Tc), in a through-hole TO-247 (IXTH) package. It operates with a maximum Rds On of 80mOhm at 23A and 10V drive. The product is RoHS3 compliant, with an operating temperature of -55°C to 150°C (TJ) and is currently active. In applications requiring reliable power switching or amplification, component availability and supply chain stability make it necessary to identify qualified equivalent and substitute models.
