JANHCA1N968B

Single Zener Diodes Overview

The JANHCA1N968B is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 20 V with a tolerance of ±5%. The device operates in a through-hole DO-7 (DO-204AA) package and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 25 ohms at a test current of 6.2 mA. It supports an operating temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a 20 V nominal breakdown voltage
• Capable of handling power dissipation up to 500 mW in a rugged through-hole package
• Engineered for extended thermal operation across a wide temperature range

Single Zener Diodes Applications

• Voltage reference circuits requiring precise regulation
• Overvoltage protection in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix 'JANHCA' indicates military-grade qualification or specific packaging variations compared to standard commercial variants. Confirm datasheet revisions match the production lot date code. Ensure the DO-7 package dimensions align with the target PCB footprint requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 20 V regulation point is required with high reliability standards. The DO-7 package suits manual assembly or wave soldering processes. Consider the 25 ohm impedance for dynamic load changes. Evaluate the 500 mW power rating against peak pulse conditions in the target circuit design to ensure safe operating area compliance.

Single Zener Diodes Part Context

This part belongs to the 1N968 series of Zener diodes produced by Microchip Technology. The JAN prefix typically denotes aerospace or military qualification standards. The HCA suffix often specifies hermetic sealing or specific lead frame materials, distinguishing it from non-hermetic commercial equivalents within the same voltage class.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N968B and JAN1N968B-1. Verify that replacement parts maintain the same DO-7 package and hermeticity requirements if environmental sealing is critical to the application.
