IRLML5203 Description

Short technical summary and product information.

The IRLML5203 is a P-Channel enhancement-mode MOSFET designed for efficient power management in space-constrained applications. It offers a drain-source voltage rating of -30V and a continuous drain current of -3.0A at 25°C ambient temperature. The device features a maximum on-resistance of 85 mOhm at VGS = 10V and 4.1A, ensuring low conduction losses.

 

This MOSFET is optimized for battery-powered and load management systems, where its low gate charge and fast switching characteristics enable high efficiency. The device can handle pulsed drain currents up to -24A, making it suitable for transient load conditions. The gate threshold voltage is typically 3V at 250µA, allowing logic-level drive.

 

The IRLML5203 is housed in a standard SOT-23 surface-mount package, which occupies minimal PCB space. It supports a wide operating junction temperature range from -55°C to +150°C. The device is supplied in tape and reel packaging with 3000 units per reel, suitable for automated assembly. It is lead-free, halogen-free, and RoHS compliant as per the referenced datasheet.
