1N1187 Description

Short technical summary and product information.

The 1N1187 is a standard recovery rectifier diode from Solid State Devices Inc (SSDI). It is designed for high current rectification applications requiring up to 300V repetitive peak reverse voltage and 35A continuous forward current. The diode features a low forward voltage drop of 1.2V at 35A and a high surge current capability of 595A (8.3ms half sine wave), making it suitable for demanding power supply and motor drive circuits.

 

The device is housed in a rugged DO-5 (DO-203AB) stud mount package, which provides excellent thermal performance with a junction-to-case thermal resistance of 0.25°C/W. The operating temperature range spans -55°C to 150°C, allowing use in harsh environments. The stud mount design ensures secure mechanical attachment and efficient heat sinking.

 

As a standard recovery diode with recovery time greater than 500ns, the 1N1187 is optimized for line frequency applications where fast switching is not required. It is commonly used in AC/DC converters, battery chargers, and industrial power supplies.
