1N4102D-1

Single Zener Diodes Overview

The Microchip Technology 1N4102D-1 is a 500 mW metallurgically bonded glass Zener diode in an axial-lead DO-35 package. It provides an 8.7 V nominal Zener voltage with a tight ±1% tolerance, indicated by the 'D' suffix. Qualified per MIL-PRF-19500/435 for high-reliability applications, it operates within a -65°C to +175°C junction temperature range and features low noise density.

Single Zener Diodes Feature Summary

• Hermetically sealed construction using internal metallurgical bonding for enhanced durability.
• Qualified to JANS reliability levels for demanding high-reliability environments.
• Low noise density performance suitable for precision regulation tasks.

Single Zener Diodes Applications

• Precision voltage reference circuits
• High-reliability military and aerospace systems
• Overvoltage protection networks

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required reliability level (JAN, JANTX, JANTXV, or JANS) and tolerance code (D for 1%). Confirm RoHS compliance status if applicable, as commercial versions differ from mil-qualified parts. Ensure lead finish specifications align with assembly requirements.

Single Zener Diodes Selection Notes

Select this component when a precise 8.7 V reference with strict tolerance is required. The axial-lead DO-35 package facilitates through-hole mounting. Consider the positive temperature coefficient at this voltage level and ensure the power dissipation limits are respected under operating conditions.

Single Zener Diodes Part Context

This device belongs to the 1N4099-1 through 1N4135-1 series of 500 mW Zener diodes. It shares the same physical package and general electrical characteristics as other members of the family, distinguished primarily by its specific breakdown voltage and manufacturing tolerance class.

Single Zener Diodes Replacement Considerations

Substitutes must match the 8.7 V nominal voltage, ±1% tolerance, and DO-35 package. Verify that alternative sources meet the same MIL-PRF-19500/435 qualification level if the application requires JANS or JAN reliability standards.

Single Zener Diodes FAQ

What does the 'D' suffix indicate in the part number?

The 'D' suffix denotes a voltage tolerance of ±1%, which is tighter than the standard ±5% tolerance found in the base JEDEC numbering.

Is this component radiation hard?

Yes, the device is inherently radiation hard as described in Microsemi MicroNote 050, making it suitable for space and high-radiation environments.
