IRL3803 Description

Short technical summary and product information.

The IRL3803 is an N-Channel Power MOSFET designed for efficient power management applications. It utilizes advanced processing techniques to achieve extremely low on-resistance per silicon area, combined with fast switching speeds and a ruggedized device design.

 

Key electrical specifications include a drain-source breakdown voltage (VDSS) of 30V and a continuous drain current (ID) of 140A at 25°C. The typical on-resistance (RDS(on)) is 5.5mΩ, with a maximum of 6mΩ specified. The device can handle pulsed drain currents up to 470A and has a maximum gate-to-source voltage of ±16V.

 

Thermal characteristics include a junction-to-case thermal resistance of 0.75°C/W and a junction-to-ambient thermal resistance of 40°C/W for PCB-mounted steady-state conditions. The operating and storage temperature range is -55°C to +175°C.

 

The IRL3803 is available in both D2Pak surface mount and TO-262 low-profile through-hole packages, making it suitable for a wide variety of applications requiring high current capability and efficient power dissipation.
