The 1N746 to 1N759A and 1N4370 to 1N4372A series are JEDEC registered silicon 500 mW Zener diodes with a flexible axial lead package. They are available in a variety of voltages and tight tolerances. These diodes are suitable for a variety of applications including power regulation, surge protection, reverse voltage protection, and voltage reference.
The Microsemi 0.5 W silicon Zener diode series includes part numbers 1N746‑1N759A and 1N4370‑1N4372A. They are JEDEC‑registered devices offering options such as internal metallurgical‑bond (-1 suffix) and various military qualifications (JAN, JANT X, JANT XV). Features include tight voltage tolerances, ESD resistance, and flexible axial‑lead mounting.
Electrical characteristics cover a voltage range of 2.4 V to 12 V, steady‑state power dissipation of 0.5 W, and operating temperatures from –65 °C to +175 °C. The devices are supplied in hermetically sealed glass DO‑35 (DO‑204AH) axial‑lead packages weighing 0.2 g, with standard and tighter tolerance options indicated by suffix letters.
