Product details

The Infineon IPS021STRL is a single-channel N-channel low-side power switch in a TO-263-3 (D²Pak) package. It handles loads up to 35 V and delivers a continuous output current of 1.8 A, with a typical on-resistance of 130 mOhm. The On/Off interface accepts a non-inverting logic-level input — no Vcc supply is required, so it gates the load directly from the microcontroller GPIO.

Ruggedness for harsh environments

Built-in fault protection — fixed current limiting and over-temperature shutdown — reduces the need for external sense resistors or thermal fuses, simplifying the BOM.

The supplier device code PG-TO263-2 confirms Infineon's specific leadframe variant.

The IPS021STRL carries an official obsolete product status.

Frequently asked questions

What is the replacement for IPS021STRL?

Buyers should evaluate functionally similar low-side switches from Infineon's current portfolio, such as the BTS or PROFET series, but pin compatibility and electrical fit must be verified against the original design.
