The 1N2970B from STMicroelectronics is a 10 Watt Zener diode series, part of the 1N2970B through 1N3015B and 1N3993A through 1N3998A family. These diodes provide voltage regulation across a broad range of current and temperature, with Zener voltages available from 3.9V to 200V. They feature standard voltage tolerances of ±5% and are housed in the industry-standard DO-4 (DO-203AA) package.
Key electrical characteristics include a nominal 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. Thermal specifications include a junction temperature range of -65°C to +175°C and a storage temperature range of -65°C to +200°C. The junction-to-case thermal resistance is rated at 12°C/W.
These hermetically sealed, welded diodes are suitable for applications requiring reliable voltage regulation. They are also noted for being non-sensitive to ESD and inherently radiation-hard. Military qualification grades such as JAN, JANTX, and JANTXV are available per MIL-PRF-19500/124 on most voltage values. RoHS compliant versions are available for commercial grades by adding an 'e3' suffix.
