Product details

Gate charge and drive budget

Total gate charge is 176 nC at 10 V. At a 100 kHz switching frequency, the average gate-drive current needed is roughly 17.6 mA — within the capability of most dedicated MOSFET drivers, but a microcontroller GPIO will not source that directly. The ±20 V Vgs max leaves headroom for gate-drive overshoot in a hard-switching topology.

Thermal envelope and package

Junction temperature range is -55 °C to 175 °C, making this part suitable for under-hood automotive or industrial environments where the die sees sustained high temperature. Maximum power dissipation is 188 W at the case — the actual limit in a real board depends on the copper area under the D2PAK tab and the airflow.

It is ROHS3 compliant.

Frequently asked questions

What are the thermal specifications of IPB120N04S401ATMA1?

Junction temperature range is -55 °C to 175 °C. Maximum power dissipation is 188 W at the case. The actual thermal performance depends on PCB copper area and airflow.
