JAN1N966B-1

Single Zener Diodes Overview

The JAN1N966B-1 is a silicon Zener diode with a nominal voltage of 16V and a tolerance of ±5%. It operates within a temperature range of -65°C to +175°C. The device features a hermetically sealed axial-lead glass DO-35 package and an internal metallurgical bond. Maximum power dissipation is 0.5W at a lead temperature of +50°C, dropping to 0.4W when mounted on a PCB at +55°C ambient. The maximum reverse leakage current is 0.5µA, and the dynamic impedance is 25 Ohms.

Single Zener Diodes Feature Summary

• Hermetically sealed axial-lead glass DO-35 package with internal metallurgical bond
• Qualified per MIL-PRF-19500/117 for JAN reliability levels
• Inherently radiation hard as described in Microsemi MicroNote 050
• Non-sensitive to ESD per MIL-STD-750 method 1020

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Military electronic systems requiring high reliability
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify that the component matches the specific JAN reliability level required by the design specifications. Confirm the package type is the standard axial-lead glass DO-35 variant rather than the MELF surface mount version. Ensure the ordering suffix corresponds to the desired RoHS compliance status, noting that commercial versions may differ from military qualified parts.

Single Zener Diodes Selection Notes

Select this component for applications requiring strict voltage tolerance and high thermal stability. The wide operating temperature range supports extreme environments. Consider the 0.5W steady-state power dissipation limit and derating curves for PCB mounting scenarios. Verify compatibility with existing board layouts due to the specific axial lead dimensions.

Single Zener Diodes Part Context

This part belongs to the 1N957B-1 through 1N992B-1 series of 0.5 watt Zener voltage regulators. The series provides voltages from 6.8 to 200 volts. Military qualified versions are available for part numbers 1N962B-1 through 1N992B-1. Commercial RoHS compliant versions are also offered.

Single Zener Diodes Replacement Considerations
