1N1188 Description

Short technical summary and product information.

The 1N1188 is a silicon standard recovery rectifier diode designed for high current rectification applications. It features a repetitive peak reverse voltage of 400V and a continuous forward current rating of 35A, with a surge non-repetitive forward current capability of 595A. The forward voltage is typically 1.2V at 35A.

 

This diode is housed in a rugged DO-5 (DO-203AB) stud mount package, offering excellent thermal performance with a junction-to-case thermal resistance of 0.25°C/W. It operates over a temperature range of -55°C to 150°C. Standard polarity configuration has the stud as the cathode; a reverse polarity variant (1N1188R) is available with the stud as the anode.

 

Typical applications include power supplies, converters, and industrial rectifier circuits where high surge capability and reliable operation are required. The standard recovery speed (>500ns) makes it suitable for line frequency applications.
