Product details

High-side switch with integrated protection for 12 V to 48 V rails

The Infineon ITS41K0SMENHUMA1 is a single-channel high-side power switch in a PG-SOT223-4 package, rated for load voltages from 4.9 V up to 60 V and a continuous output current of 200 mA. The N-channel output is controlled by a simple On/Off logic input with non-inverting polarity. Built-in fault protection — current limiting (fixed), over-temperature shutdown, and over-voltage clamping — lets it handle short circuits and inductive load dump without adding external clamp diodes.

Frequently asked questions

What is the recommended replacement or equivalent for ITS41K0SMENHUMA1?

The ITS41K0SMENHUMA1 has no official replacement listed. The BTS142DATMA1 is a different-function low-side switch with 23 mOhm Rds(on) and 4.6 A output — not a pin-compatible substitute. For a functional equivalent, look at other Infineon HITFET high-side switches in the same SOT223-4 package.

Can the ITS41K0SMENHUMA1 be used as a high-side switch with 5V logic?

Yes. The input is non-inverting and the part does not require a Vcc supply — it is self-powered from the load voltage. A 5 V logic signal on the On/Off pin is compatible with the input threshold range, though the datasheet should be consulted for exact VIH/VIL levels.
