Dual P-Channel 30V MOSFET for high-side switching
The IRF7316TRPBF is a dual P-Channel MOSFET from the HEXFET series, rated for 30V drain-to-source and 4.9A continuous drain current.
On-resistance is 58 mOhm maximum at 4.9A with a 10V gate drive. At the logic-level threshold of 1V, the device is fully enhanced; the 34 nC total gate charge at 10V means a 100 kHz switching frequency draws about 3.4 mA average from the gate driver, well within the output capability of a typical MCU pin or dedicated gate-driver IC.
The 8-SOIC package (0.154-inch width) is a standard surface-mount footprint.
It is ROHS3 compliant.
