What this low-side switch does in a 12V/24V load circuit
The Infineon IPS1011STRLPBF is a single-channel, low-side N-channel power switch rated for a 28V maximum load voltage and 6.5A continuous output current. It switches grounded loads — solenoids, relays, lamps, or small motors — with a typical on-resistance of 10 mOhm, keeping conduction loss low in the D2PAK package. The switch is self-protected with fixed current limiting and over-temperature shutdown, so it can survive a shorted load or stalled motor without external sense components. The input is non-inverting and the gate drive requires no external Vcc supply — the internal charge pump is self-powered from the load voltage.
Obsolete — sourcing path and replacement reality
Buyers filling a BOM line for this part will need to source from independent distribution on the surplus market, or qualify a pin-compatible replacement. Because no official successor is listed, the replacement decision falls to the design team.
Package and thermal handling in the D2PAK
For sustained 6.5A operation, a 1-ounce copper pour of at least 6 cm² on the top layer is typical to keep the junction below 150°C.
