The IRLML6402TRPBF from Infineon (International Rectifier) is a -20V single P-channel HEXFET power MOSFET in a Micro3 (SOT-23) package featuring ultra-low on-resistance, fast switching, and logic-level gate drive. This P-channel MOSFET delivers a maximum RDS(on) of 65 mΩ at VGS = -4.5V with a continuous drain current rating of -3.7A at 25°C (-2.2A at 70°C) and pulsed drain current of -22A. Its logic-level gate is fully specified at -2.5V and -4.5V, making it directly drivable by 3.3V and 5V microcontrollers. The thermally enhanced large-pad leadframe incorporated into the SOT-23 package achieves the industry's smallest footprint with a low profile under 1.1mm, ideal for space-constrained portable applications. 
Application Scenarios
The IRLML6402TRPBF P-channel MOSFET is extensively deployed in battery management and load switching circuits for portable electronics including smartphones, tablets, wearables, and PCMCIA cards where space is at a premium. As a high-side switch, it serves power muxing, reverse-battery protection, and power-rail isolation in low-voltage systems. Typical applications include battery charger switches, DC/DC converter synchronous rectification at low voltage, load switches for USB power paths, motor drivers for small actuators, and general power management in IoT devices, consumer electronics, and compact industrial control boards requiring logic-level switching.
Frequently Asked Questions
Q1: Can the IRLML6402TRPBF be driven directly from a 3.3V microcontroller GPIO? Yes, the logic-level gate is specified at -2.5V, ensuring adequate enhancement at 3.3V for full current capability up to -3.1A.
Q2: What is the body diode forward voltage drop? The integrated source-drain diode exhibits -1.2V maximum forward voltage at IS = -1.0A with 29ns typical reverse recovery time.
