JAN1N976B-1/TR

Single Zener Diodes Overview

The JAN1N976B-1/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation and protection applications. It features a nominal Zener voltage of 43 V with a power dissipation rating of 500 mW. The component utilizes a DO-204AH (DO-35) through-hole package and operates within a temperature range of -65°C to +175°C. Key electrical specifications include a maximum reverse leakage current of 500 nA, a Zener impedance of 93 Ohms at a test current of 3 mA, and a forward voltage of 1.1 V. The device is supplied in reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal Zener voltage of 43 V
• Capable of handling up to 500 mW of power dissipation
• Operates reliably across an extended temperature range from -65°C to +175°C
• Constructed in a standard through-hole DO-204AH (DO-35) axial leaded package

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific suffix /TR indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status as indicated in official documentation, noting that military-grade variants may have different environmental certifications. Ensure the DO-204AH package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Single Zener Diodes Selection Notes

Select this component when a precise 43 V reference is required in through-hole designs. Consider the 93 Ohm impedance and 500 nA leakage current for sensitive analog applications. The wide operating temperature range makes it suitable for harsh environments where standard commercial parts might fail.

Single Zener Diodes Part Context

This part belongs to the JAN1N976 series of Zener diodes produced by Microchip Technology. It is functionally similar to other industry-standard 43 V Zener diodes but offers specific reliability characteristics associated with the JAN series. The /TR suffix distinguishes it from bulk-packaged equivalents like the JAN1N976B-1.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N976B-1 (bulk pack) or generic 1N976B equivalents if package and tolerance specifications align. Verify that replacement parts meet the same 500 mW power rating and 43 V Zener voltage tolerance.
