Product details

The BSO303SP is a P-Channel enhancement-mode MOSFET from Infineon's OptiMOS® -P series.

7.2 A continuous drain — thermal-package limited, not silicon-limited

The continuous drain current is rated at 7.2 A at 25 °C ambient, with maximum power dissipation of 1.56 W. Above 25 °C the current must be derated per the PG-DSO-8-1 package thermal resistance.

54 nC gate charge — drive current needed for switching frequency

Total gate charge is 54 nC at 10 V.

Package and footprint — PG-DSO-8-1 (SOIC-8)

The gate threshold voltage is 2 V maximum at 100 µA drain current.
