# IRLML6244TRPBF (Component)
## Description
MOSFET N-CH 20V 6.3A SOT-23
The IRLML6244TRPBF is an N-channel enhancement-mode power MOSFET from Infineon Technologies (originally International Rectifier HEXFET series). It is designed for low-voltage power switching applications such as load switching, DC-DC converters, and LED control.
It comes in a compact SOT-23 (Micro3™) surface-mount package, making it suitable for space-constrained PCB designs while still handling relatively high current for its size.
Key Features
Drain-Source Voltage (VDS): 20 V
Continuous Drain Current: up to ~6.3 A (at 25°C)
Very low RDS(on):
~21 mΩ @ VGS = 4.5 V
~27 mΩ @ VGS = 2.5 V
Low gate threshold voltage (~0.5–1.1 V typical range) (note: not a switching guarantee)
Gate-to-source voltage rating: ±12 V
Low power loss due to low on-resistance
High efficiency switching for low-voltage systems
Power dissipation: ~1.3 W (thermal limited in SOT-23 package)
Fast switching performance (low gate charge ~8.9 nC)
Operating temperature range: −55°C to +150°C
RoHS compliant (lead-free, halogen-free)
Typical Applications
Low-side load switching (MCUs, GPIO control)
LED strip / RGB LED drivers
Battery-powered systems
DC-DC converter switching
Small motor or relay driving
General-purpose power management in compact electronics
Important Design Note
Even though it has a low VGS(th), this MOSFET is not selected based on threshold voltage. What matters is the RDS(on) at your gate drive voltage (2.5 V / 3.3 V / 5 V) to ensure it fully turns on with minimal heating.
