1N2992B Description

Short technical summary and product information.

The 1N2992B is a 10-watt Zener diode designed for voltage regulation applications. It is part of the 1N2970B-1N3015B series and is available in a stud mount DO-4 (DO-203AA) package. This diode offers a maximum Zener impedance of 11Ω and a reverse leakage current of 5µA at 29.7V. The forward voltage is specified at 1.5V maximum at 2A.

 

The device is rated for a junction temperature range of -65°C to 175°C and has a thermal resistance junction-to-case of 12°C/W. Power dissipation is 10W at a case temperature of 55°C, with derating above that. The stud mount design allows for efficient heat sinking in high-power applications.

 

Typical applications include voltage regulation, overvoltage protection, and reference voltage sources in power supplies and industrial equipment. The hermetically sealed construction ensures reliability in harsh environments. The device is available in military qualification grades (JAN, JANTX, JANTXV) per MIL-PRF-19500/124.
