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. #CommonPartsLibrary #Transistor #FET #IRLML6244 #MOSFET #NChannelMOSFET #PowerElectronics #SOT23 #Infineon #HEXFET #LEDDriver #LowSideSwitch #ElectronicsComponents
