250 V P-Channel MOSFET in a SOT89 — what it is for
The Infineon BSS192PH6327FTSA1 is a P-Channel MOSFET from the SIPMOS® family, rated for 250 V drain-to-source voltage and 190 mA continuous drain current at 25°C. Packaged in a PG-SOT89 surface-mount case, it is built for medium-voltage switching and load management in space-constrained designs. The 12 Ohm maximum on-resistance at 190 mA and 10 V gate drive keeps conduction losses predictable for low-current high-voltage rails.
Where it fits in a design
This is a high-voltage P-Channel switch for load disconnect, reverse-polarity protection, and high-side switching in power supplies, battery management, and industrial controls. The P-Channel polarity means you can switch the positive rail without a charge pump or bootstrap circuit — useful when board space is tight and you want a simple on/off control from a low-voltage logic pin. The SOT89 footprint is small enough for handheld and portable equipment but still hand-solderable for prototyping.
Lifecycle and sourcing reality
No last-time-buy or end-of-life notice is on record. For a BOM line that needs a 250 V P-Channel MOSFET in a SOT89, this part is a current, factory-supported choice.
