RSJ450N04TL Equivalent & Substitute Parts Reference

Part Overview

The RSJ450N04TL is an N-Channel MOSFET manufactured by Rohm Semiconductor in the "Transistors, FETs, MOSFETs" category. It is designed for surface mount applications, featuring a drain to source voltage (Vdss) of 40V and a continuous drain current (Id) of 45A at 25°C. The device is housed in a TO-263-3, D2PAK (2 Leads + Tab), TO-263AB package with an LPTS supplier device package. It is RoHS3 compliant, with a moisture sensitivity level (MSL) of 1 (Unlimited), and is REACH unaffected. The part status is noted as "Not For New Designs," which necessitates determining suitable parametric equivalents and substitutes for ongoing production and maintenance requirements.
