# IRLML2502 (Component) ## Description MOSFET N-CH 20V 3.6A SOT-23 The IRLML2502 is a small-signal N-channel enhancement mode power MOSFET designed for low-voltage, high-efficiency switching applications. It is commonly used as a load switch or power control transistor in compact electronic systems such as battery-powered devices, LED drivers, and DC-DC converters. It features a low on-resistance (RDS(on)), which allows it to switch higher currents with minimal power loss and heat generation. The device is optimized for logic-level gate drive, meaning it can be driven directly from microcontrollers (like 3.3 V or 5 V systems). It is packaged in a compact SOT-23 (Micro3) surface-mount package, making it suitable for space-constrained PCB designs. Key Features N-channel enhancement mode MOSFET Drain-source voltage (VDS) up to 20 V Continuous drain current up to ~4.2 A (at 25°C) Very low RDS(on) ≈ 45 mΩ @ VGS = 4.5 V Logic-level gate drive capability (works with 2.5–4.5 V signals) Fast switching performance Compact SOT-23 (Micro3) surface-mount package Low gate charge for efficient switching Suitable for battery-powered and low-voltage applications RoHS compliant, lead-free design #IRLML2502 #MOSFET #NChannelMOSFET #PowerElectronics #SOT23 #LogicLevelMOSFET #PowerSwitch #ElectronicComponents #EmbeddedSystems #PCBDesign ## Component Details - **Owner:** lcsc - **Created:** 11/1/2024 - **Last Updated:** 6/10/2026 - **Visibility:** Public - **Product Info Url:** https://lcsc.com/product-detail/MOSFET_HUASHUO-IRLML2502_C518800.html - **Datasheet URL:** https://storage.googleapis.com/graviton-electric-symbols/document_assets/lcsc/2005121032_HUASHUO-IRLML2502_C518800.pdf - **Part Type:** MOSFETs - **JLCPCB Part Class:** Extended Part - **LCSC Part Number:** C518800 - **License:** https://creativecommons.org/licenses/by/4.0/ - **Manufacturer Part Number:** IRLML2502 - **Manufacturer Name:** HUASHUO(华朔) - **Package or Case Code:** SOT-23-3_L2.9-W1.3-P1.90-LS2.4-BR - **Used in:** 40 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
