# Infineon 111-4095PBF: SmartRectifier Low-Side MOSFET Gate Driver The 111-4095PBF is a SmartRectifier low-side gate driver in an 8-SOIC package. It is intended for N-channel MOSFET synchronous rectification, with a 12 V to 18 V supply, non-inverting input thresholds around 2 V / 2.15 V, and peak drive near 2 A source / 7 A sink. Typical rise and fall times are about 18 ns and 10 ns. That asymmetric strength is common in SR drivers: strong sink helps turn the sync FET off quickly and limit body-diode conduction, while a milder source edge can reduce ringing. Validate the logic thresholds against your PWM controller’s SR pin, keep the gate loop short on the SOIC-8 footprint, and confirm the −25 °C to 125 °C junction rating for the power stage ambient. Cross-check SmartRectifier family errata before releasing a high-volume PSU.
