Product details

28 V low-side switch with 40 mOhm Rds(on)

The Infineon IPS1031STRLPBF is a single-channel low-side N-channel power switch in a D2PAK surface-mount package. It switches a 28 V max load rail with a typical on-resistance of 40 mOhm, delivering up to 3.3 A continuous output.

Built-in fault protection for point-of-load switching

Fixed current limiting and over-temperature protection are integrated on-die, so a shorted load or stalled motor won't immediately blow the switch or the PCB trace. The device latches off under over-temperature and auto-restarts when the junction cools — useful for driving lamps, solenoids, or small motors in industrial or automotive panels where a fuse is impractical to replace.

Frequently asked questions

Is IPS1031STRLPBF obsolete?

Buyers need to know whether this part is still in production or if they must find a replacement for their BOM.

What is the replacement for IPS1031STRLPBF?

Since the part is obsolete, the most critical conversion step is to offer a drop-in or functional replacement.

Where can I buy IPS1031STRLPBF?

Sourcing buyers need to quickly locate distributors who still have stock to fill their BOM line.

What is the datasheet for IPS1031STRLPBF?

Design engineers and techs require the official datasheet to validate fit, pinout, and electrical characteristics.

What is the price of IPS1031STRLPBF?

Buyers comparing alternatives or checking budget need current pricing, especially for legacy parts with diminishing stock.

What is the pinout of IPS1031STRLPBF?

Maintenance techs replacing a failed unit need pin-to-pin compatibility to avoid board redesign.
