1N2970B Description

Short technical summary and product information.

The 1N2970B from NAE is a 10 Watt Zener diode series, part of the 1N2970B-1N3015B and 1N3993A-1N3998A families. These diodes provide voltage regulation values ranging from 3.9V to 200V, making them suitable for a broad spectrum of applications.

 

Key electrical characteristics include a steady-state power dissipation of 10W at 55°C, with a derating of 0.083 W/°C above this temperature. The forward voltage is typically 1.5V at 2.0A, and standard voltage tolerances are ±5%. The junction temperature range is -65°C to +175°C, with a storage temperature range of -65°C to +200°C.

 

Packaged in the industry-standard DO-4 (DO-203AA) case, the 1N2970B is hermetically sealed and features internal solder bond construction. It is designed for through-hole mounting. The diode is inherently radiation-hard and non-sensitive to ESD, per MIL-STD-750 method 1020.

 

Military qualification grades such as JAN, JANTX, and JANTXV are available per MIL-PRF-19500/124. Commercial versions with RoHS compliance are available by adding the 'e3' suffix.
