The Infineon IRLL024NTRPBF is a 55V single N-channel logic-level power MOSFET based on IR MOSFET™ / HEXFET® technology. It combines low on-resistance, fast switching, and avalanche capability in a compact SOT-223 surface-mount package for load switching, DC motors, SMPS, lighting, and battery-powered applications. Infineon currently lists the exact orderable part as Active.
Maximum drain-to-source voltage is 55V. Maximum RDS(on) is 65mΩ at VGS = 10V, 80mΩ at 5V, and 100mΩ at 4V. Gate-threshold voltage ranges from 1.0V to 2.0V, while the device is characterized for low-voltage logic-level gate drive.
Drain-current capability depends on PCB thermal conditions. The datasheet specifies up to 4.4A continuous drain current at 25°C on a one-square-inch copper board, while the minimum recommended FR-4 footprint is rated at 3.1A. Pulsed drain current is rated up to 12A.
Typical total gate charge is 10.4nC, with 5.5nC gate-to-drain charge. Typical switching characteristics under the specified test conditions include 7.4ns turn-on delay, 21ns rise time, 18ns turn-off delay, and 25ns fall time.
The device is fully avalanche rated with up to 120mJ single-pulse avalanche energy and supports a maximum ±16V gate-to-source voltage. Junction temperature ranges from -55°C to +150°C.
The exact IRLL024NTRPBF is supplied in a SOT-223 / TO-261AA package, with 2,500 devices per tape-and-reel and MSL Level 1 classification. Infineon’s current product page lists the device as RoHS compliant and halogen free.
