JAN1N965B-1

Single Zener Diodes Overview

The JAN1N965B-1 is a silicon Zener diode with a nominal voltage of 15 V and a test current of 8.5 mA. It features a maximum dynamic impedance of 16 Ohms and a maximum reverse leakage current of 0.5 µA at the specified voltage. The device operates within a temperature range of -65°C to +175°C, dissipating up to 400 mW when mounted on a PCB or 500 mW at a lead temperature of 50°C. It has a positive temperature coefficient of 0.082 %/°C and is housed in a hermetically sealed DO-35 glass package.

Single Zener Diodes Feature Summary

• Hermetically sealed axial-lead glass construction for environmental protection
• Qualified per MIL-PRF-19500/117 for military reliability standards
• Inherently radiation hard as described in Microsemi MicroNote 050
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Reference voltage sources in aerospace and defense circuits
• Overvoltage protection in harsh environments

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required military qualification level (JAN) and tolerance suffix (B). Confirm RoHS compliance status if applicable, noting that commercial versions may differ from military qualified units. Ensure ordering specifications align with the manufacturer's nomenclature guidelines for metallurgically bonded devices.

Single Zener Diodes Selection Notes

Select this component for applications requiring strict voltage stability across extreme temperatures. The 15 V rating suits mid-range reference needs. Consider the low leakage current and high thermal resistance limits when designing heat dissipation paths. Verify that the system environment meets the radiation hardness requirements defined in the associated technical notes.

Single Zener Diodes Part Context

This component belongs to the 1N957B-1 through 1N992B-1 series of 0.5 W Zener diodes manufactured by Microchip Technology. The JAN prefix indicates it meets specific military reliability levels. The series provides a wide selection of voltages from 6.8 V to 200 V in standard axial-lead packages.

Single Zener Diodes Replacement Considerations

Compatible substitutes include JANTX1N965B-1 and JANTXV1N965B-1, which share identical electrical characteristics but offer different military qualification levels.
