IRL3803SPBF Description

Short technical summary and product information.

The Infineon IRL3803SPBF is a high-performance N-Channel MOSFET suitable for various power switching applications. It offers a maximum drain-source voltage (Vds) of 30V and a continuous drain current (Id) of up to 120A at 25°C with a Vgs of 10V.

 

This MOSFET boasts a low on-resistance (Rds(on)) of 0.0075 Ohm maximum at Vgs=10V and Id=120A, and a typical Rds(on) of 0.0065 Ohm at Vgs=10V and Id=25A. The gate threshold voltage (Vgs(th)) is typically 4V when Id is 25A. The total gate charge (Qg) is approximately 150nC at Vgs=10V.

 

With a wide operating temperature range from -55°C to 175°C, the IRL3803SPBF is designed for demanding environments. It is housed in a surface-mount TO-263-3, D²Pak package, facilitating integration into compact designs. The typical junction-to-ambient thermal resistance is 62.5°C/W, and junction-to-case is 0.7°C/W, indicating good thermal management capabilities.
