JAN1N968D-1

Single Zener Diodes Overview

The JAN1N968D-1 is a silicon Zener voltage regulator diode with a nominal breakdown voltage of 20 V and a tolerance of ±1%. It operates in the DO-35 (DO-204AH) axial-lead glass package. The device features an internal metallurgical bond and is qualified to MIL-PRF-19500/117 standards. It provides a maximum steady-state power dissipation of 0.5 W at a lead temperature of +50°C, with a test current of 6.2 mA. The unit supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-35 package with internal metallurgical bonding for enhanced reliability.
• Qualified per MIL-PRF-19500/117 specifications for JAN level military applications.
• 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 generation in precision electronic circuits.
• Overvoltage protection in harsh environment systems.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'D' corresponds to the required ±1% voltage tolerance. Confirm RoHS compliance status, as non-RoHS versions are standard for this military qualification. Ensure procurement channels support the specific MIL-PRF-19500/117 JAN level requirements. Check for any applicable PCNs regarding assembly site or packaging label changes before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a precise 20 V reference is needed in a ruggedized axial-lead form factor. The ±1% tolerance offers tighter control than standard commercial equivalents. Consider the thermal resistance values and derating curves if mounting on PCBs versus using extended leads. Verify that the 0.5 W power rating aligns with the expected circuit load and ambient temperature conditions.

Single Zener Diodes Part Context

This part belongs to the 1N957B-1 through 1N992B-1 series of 0.5 W silicon Zener diodes manufactured by Microchip Technology. The series covers a wide voltage selection from 6.8 V to 200 V. The JAN1N968D-1 specifically utilizes the 'D' suffix to denote the tightest 1% voltage tolerance available within this product family.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 20 V nominal voltage, ±1% tolerance, and DO-35 package. Equivalent parts should also meet MIL-PRF-19500/117 qualifications for JAN level reliability. Verify pinout compatibility and thermal characteristics before substitution.

Single Zener Diodes FAQ

What does the 'D' suffix indicate in the JAN1N968D-1 part number?

The 'D' suffix indicates a Zener voltage tolerance of ±1%, which is tighter than the standard ±5% (B suffix) or ±2% (C suffix) options.

Is the JAN1N968D-1 RoHS compliant?

No, the JAN1N968D-1 is not RoHS compliant. RoHS compliance is only available on commercial grade versions of this series.
