Product details

Single high-side switch for automotive loads

The Infineon BTS41K0SMENHUMA1 is a single-channel high-side power switch in the Automotive series, built to drive resistive, inductive, and capacitive loads in 12V and 24V vehicle electrical systems. It integrates an N-channel MOSFET with a typical on-resistance of 800 mOhm and a maximum load voltage rating of 60V, giving headroom for load-dump transients on a nominal 12V rail.

Thermal and protection envelope

The fault protection block includes over-temperature and over-voltage shutdown, and the Auto Restart feature re-enables the output after a thermal fault cools, reducing the need for external watchdog circuitry.

Package and supply simplicity

The device comes in a PG-SOT223-4 surface-mount package (TO-261-4 equivalent), a four-pin footprint with a large drain tab for heat sinking into the PCB copper plane. No external Vcc supply is required — the switch is self-powered from the load voltage, so the interface is a single On/Off logic input controlling the output with a 1:1 ratio.

Frequently asked questions

Is BTS41K0SMENHUMA1 still active or obsolete?

Buyers need to know if the part is still being manufactured before committing to a design or placing a large order.

What is the price of BTS41K0SMENHUMA1 in 1000-piece quantities?

Volume pricing directly affects BOM cost and sourcing decisions for procurement teams.

Where to buy BTS41K0SMENHUMA1 with stock in USA?

Immediate availability and local stock reduce lead time and shipping costs for urgent production needs.

What is the direct replacement for BTS41K0SMENHUMA1?

If the part becomes scarce, knowing a drop-in alternative avoids redesign and long sourcing delays.

Does BTS41K0SMENHUMA1 meet AEC-Q100 automotive standard?

Automotive applications require qualified parts; AEC-Q100 compliance is often mandatory for design-ins.

Can I use BTS41K0SMENHUMA1 for 12V automotive load?

Engineers need to confirm voltage/current margins and protection features for the specific load.
