Microsemi 1N746‑1N759A and 1N4370‑1N4372A DO‑35 Zener Diode Data Sheet
The Microsemi 1N746‑1N759A and 1N4370‑1N4372A series are 0.5 W glass axial‑lead Zener diodes in a DO‑35 (DO‑204AH) package. They provide selectable Zener voltages from 2.4 V to 12 V with standard 5 % or 10 % tolerances, and tighter tolerances using suffix letters.
These devices operate over a wide temperature range (‑65 °C to +175 °C) and include options such as internal metallurgical bond (‑1 suffix) and military‑grade screening (JAN, JANTX, JANTXV). Electrical characteristics, mechanical dimensions, and packaging details are provided for design and reliability assessment.
