P-channel power switch for automotive loads
The STMicroelectronics STD95P3LLH6AG is a P-channel STripFET H6 power MOSFET built for automotive-grade switching — AEC-Q101 qualified, rated for a drain-source voltage of 30 V and a continuous drain current of 80 A at 25 °C case temperature. The DPAK (TO-252-3) surface-mount package with exposed tab carries 104 W of dissipation (Tc) when properly heatsunk.
The drive voltage range spans 4.5 V to 10 V for minimum and maximum Rds(on), so a 5 V logic-level gate signal works but the on-resistance roughly doubles versus the 10 V figure; the designer should verify the actual Rds(on) at the chosen gate voltage from the transfer curve.
