200 V P-channel in a PowerPAK SO-8 — high-side switching for 48 V automotive buses
The P-channel polarity simplifies high-side drive circuits — no charge pump or bootstrap needed — which matters in 48 V mild-hybrid bus architectures or 72 V truck systems where the gate drive is referenced to the source.
At that operating point the conduction loss is about 4.4 W — well within the 68 W package power dissipation rating, but the thermal path through the PowerPAK SO-8 exposed pad needs a solid via stitch to the ground plane to keep the junction below 175 °C. The drive voltage range spans 6 V to 10 V for optimum Rds(on); at 6 V the on-resistance will be higher, so budget the gate drive rail accordingly if the system runs on a 5 V or 3.3 V logic supply.
That gate charge is moderate for a 200 V device — the driver sees about 8.5 µC per switching event at 100 kHz, which a standard automotive gate driver IC can handle without excessive dissipation.
