Product details

The Texas Instruments TPS259521DSGT is an electronic fuse (eFuse) that protects a downstream load from overcurrent, overvoltage, and inrush events. It handles a continuous 4 A output and accepts an input from 2.7 V up to 18 V.

Temperature grade — industrial and automotive under-hood

The 125°C ceiling is the junction limit, not the ambient — derate the 4 A output above about 85°C ambient depending on the copper area under the 8-WSON exposed pad.

Package and footprint — 8-WSON with exposed pad

The base product number is TPS259521; the DSGT suffix denotes the 8-WSON package and tape-and-reel / cut-tape shipping options.

Frequently asked questions

What is the TPS259521DSGT?

The TPS259521DSGT is an electronic fuse (eFuse) from Texas Instruments that protects a load from overcurrent, overvoltage, and inrush.

Is TPS259521DSGT compatible with 5V input?

Yes — the 2.7 V to 18 V input range covers 5 V rails directly, with margin above and below for transients.
