This document describes the features and characteristics of the 10 watt Zener diodes produced by Microsemi. These diodes provide voltage regulation in a range of 3.9V to 200V. They have low thermal resistance and can handle up to 10 watts of power. Additionally, these diodes are available with military qualifications and Microsemi offers other Zener products for higher and lower power applications.
The document provides specifications for Microsemi's 10 W Zener diode series 1N2970‑1N3015B and 1N3993‑1N4000A. These devices offer Zener voltages from 3.9 V to 200 V and are supplied in a hermetically sealed DO‑4 (DO‑203AA) metal case.
Electrical characteristics include a maximum power dissipation of 10 W, junction temperature range –65 °C to +175 °C, and typical thermal resistance of 10 °C. Standard polarity is anode‑to‑case for the 1N2970‑1N3015B range and cathode‑to‑case for the 1N3993‑1N4000A range, with reverse‑polarity options indicated by an “R” suffix. Tolerance options are provided via suffixes (A, B, C, D).
| Zener Voltage Range | 3.9 V to 200 V |
|---|---|
| Maximum Power Dissipation | 10 W |
| Junction Temperature Range | -65 °C to +175 °C |
