The IRSF3031 is a three-terminal monolithic SMART POWER MOSFET with built-in short circuit, over-temperature, ESD and over-voltage protections and dual set/reset threshold input. The on-chip protection circuit latches off the power MOSFET in case the drain current exceeds 4A (typical) or the junction temperature exceeds 165C (typical) and keeps it off until the input is driven below the Reset Threshold voltage. The drain-to-source voltage is actively clamped at 55V (typical) prior to the avalanche of the power MOSFET, thus improving its performance during turn-off with inductive loads. The input requirements are very low (100A typical) which makes the IRSF3031 compatible with most existing designs based on standard power MOSFETs.
