11DQ03 Description

Short technical summary and product information.

The Infineon Technologies 11DQ03 is a Schottky rectifier housed in a DO-41 package. It is designed for applications such as switching power supplies, converters, and free-wheeling diodes.

 

Key electrical characteristics include a peak repetitive reverse voltage of up to 40V and an average forward current of 1.1A at 75°C. The device exhibits a low forward voltage drop, with typical values of 0.47V at 1A and 25°C. It also features a high frequency operation capability and a guard ring for enhanced reliability.

 

The rectifier is constructed with high purity, high temperature epoxy encapsulation for mechanical strength and moisture resistance. The terminals are Tin Lead-free plated, and the device is Pb-Free compliant. Its low profile, axial leaded outline makes it suitable for various PCB mounting requirements.

 

Applications include switching power supplies, converters, free-wheeling diodes, and reverse battery protection. The 11DQ03 is designed for high reliability and long-term performance in demanding electronic circuits.
