P-channel at this voltage is the part you reach for when you want a simple high-side switch without a charge pump — the gate just needs to be pulled below the source to turn on. ## Gate drive and switching — what the numbers mean at the bench The gate threshold voltage is specified at 4 V maximum with 380 µA drain current — that 4 V ceiling means a 5 V logic signal from a microcontroller or gate driver will turn this FET fully on, but a 3.3 V logic rail is marginal and may not guarantee the full Rds(on). Total gate charge is 12 nC at 10 V, so a 100 mA gate driver can switch it in about 120 ns — fast enough for a 100 kHz SMPS, but the 319 pF input capacitance at 25 V drain-source means the driver sees a capacitive load that rings if the layout is sloppy. ## Package and thermal — the copper pad is the heatsink The PG-SOT223-4-21 package is a surface-mount power package with the tab as the drain. The 1.8 W maximum power dissipation at 25°C ambient assumes a standard FR-4 board with minimum copper — if you need to push the full 980 mA continuous at high ambient, the tab needs a generous copper pour and vias to a ground plane to keep the junction below 150°C. ## Lifecycle and sourcing — still in production ROHS3 compliant, no exemptions expiring.","metaTitle":"Infineon BSP321PL6327 P-Channel MOSFET, 100 V, 980 mA","metaDescription":"Infineon SIPMOS P-channel MOSFET, 100 V Vds, 980 mA Id, 900 mOhm Rds(on) at 10 V.
