45 mOhm Rds(on) high-side switch for 12 V automotive loads
The BTS50451EJAXUMA1: The On/Off interface and 1:1 input-to-output ratio make it a direct replacement for a relay or discrete MOSFET in a 12 V automotive or industrial load circuit, with built-in protection that eliminates external clamp diodes and fuses for many fault conditions.
Fault protection and thermal range
The device integrates current limiting, open-load detection, over-temperature shutdown, over-voltage clamp, and under-voltage lockout — covering the common failure modes in a 12 V vehicle power distribution box or industrial actuator driver. Rated for a junction temperature range of -40 to 150 °C, it suits under-hood or engine-bay environments where ambient temperatures push past 105 °C.
Package and sourcing posture
Supplied in a PG-DSO-8-43-EP (8-SOIC with exposed pad) package on tape and reel, the BTS50451EJAXUMA1 is an active Infineon PROFET part, ROHS3 compliant.
