JAN1N981D-1

Single Zener Diodes Overview

The JAN1N981D-1 is a silicon Zener diode with a nominal voltage of 68 V and a maximum power dissipation of 500 mW. It features a tight tolerance of ±1% and operates within a temperature range of -65°C to +175°C. The device utilizes a hermetically sealed axial-lead glass DO-35 (DO-204AH) package and is qualified per MIL-PRF-19500/117.

Single Zener Diodes Feature Summary

• Hermetically sealed axial-lead glass construction
• Military qualification per MIL-PRF-19500/117
• Tight voltage tolerance of ±1%
• Wide operating temperature capability

Single Zener Diodes Applications

• Voltage regulation in military systems
• Precision reference circuits
• Harsh environment electronics

Single Zener Diodes Procurement Notes

Verify the specific suffix 'D' indicates the required ±1% tolerance level. Confirm that the non-RoHS compliant status aligns with project requirements, as RoHS compliance is available only on commercial grade versions. Ensure the order specifies the correct packaging format if tape and reel options are needed.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy is critical for precision applications. The wide temperature range supports operation in extreme environments. Verify that the 500 mW power rating meets the thermal dissipation needs of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N957B-1 through 1N992B-1 series of 0.5 W Zener regulators. The 'JAN' prefix denotes a specific military reliability level. The 'D' suffix specifically defines the tighter ±1% voltage tolerance compared to standard or looser tolerance variants.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N981B-1 and JAN1N981C-1, which share the same package and qualification but offer different voltage tolerances.
