IRLR8503 Description

Short technical summary and product information.

The Infineon IRLR8503 is an N-Channel power MOSFET designed for high-efficiency DC-DC converters. It features a drain-source voltage rating of 30V and a continuous drain current of 44A at 25°C. The device achieves a maximum on-resistance of 16 mOhm at 10V gate drive, minimizing conduction losses.

 

Optimized for synchronous buck converter topologies, this MOSFET offers low gate charge (20 nC max at 5V) and fast switching characteristics with typical turn-on and turn-off delays of 10 ns and 11 ns respectively. The device comes in a surface-mount D-Pak (TO-252) package and supports operating temperatures from -55°C to 150°C.

 

The IRLR8503 is suitable for CPU core voltage regulation and other high-current power conversion applications requiring low Rds(on) and efficient switching.
