Product details

High-side switch for automotive loads — what this PROFET delivers

The BTS40K21EJCXUMA1 is a single-channel, N-channel high-side switch from Infineon's PROFET family, AEC-Q100 qualified for automotive applications. It switches a 5V to 36V load with a typical on-resistance of 200 mOhm and delivers up to 1.5A continuous output.

200 mOhm Rds(on) and 150°C junction — thermal budget for underhood duty

The 200 mOhm typical Rds(on) sets the conduction loss floor. The junction is rated to 150°C. A 5V to 36V load supply range covers nominal 12V and 24V automotive electrical systems, including load-dump transients within the absolute maximum ratings. The device integrates fault protection: current limiting, open-load detection, over-temperature shutdown, over-voltage clamp, and under-voltage lockout.

PG-DSO-8 with exposed pad — layout and thermal relief

The package is PG-DSO-8, a surface-mount design with exposed pad.

Obsolete — sourcing through independent distribution

This part carries an Obsolete lifecycle status.

Frequently asked questions

What is the Rds(on) of BTS40K21EJCXUMA1?

The typical Rds(on) is 200 mOhm. This is specified at 25°C junction temperature; actual on-resistance increases with junction temperature, roughly doubling at 150°C.
