1N4102-1

Single Zener Diodes Overview

The Microchip Technology 1N4102-1 is a 500 mW metallurgically bonded glass Zener diode in the axial-lead DO-35 package. It provides an 8.7 V nominal Zener voltage with a standard 5% tolerance. The device operates within a junction temperature range of -65°C to +175°C and features a maximum reverse current of 6.7 µA at the specified test current of 250 µA.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for high reliability
• Hermetically sealed glass DO-35 package
• Inherently radiation hard design
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation over broad ranges of current and temperature
• High reliability applications requiring MIL-PRF-19500/435 qualification
• Circuits requiring minimal capacitance characteristics

Single Zener Diodes Procurement Notes

Verify that the specific order matches the JEDEC registered part number 1N4102-1. Confirm the required reliability level, as JAN, JANTX, JANTXV, and JANS qualifications are available per MIL-PRF-19500/435. Ensure the package type corresponds to the axial-lead DO-35 style unless a surface mount variant is explicitly requested.

Single Zener Diodes Selection Notes

Select this component when a 500 mW power rating and 8.7 V breakdown voltage are required. Consider the positive temperature coefficient of +0.075 %/°C for thermal stability analysis. Verify that the operating environment supports the specified -65°C to +175°C junction temperature range.

Single Zener Diodes Part Context

This component belongs to the 1N4099-1 through 1N4135-1 series of 500 mZener voltage regulators. These devices share common packaging and manufacturing processes but differ in nominal Zener voltage and impedance specifications. The series covers voltages from 1.8 V to 100 V.

Single Zener Diodes Replacement Considerations

Substitutes must match the 8.7 V nominal Zener voltage, 500 mW power dissipation, and DO-35 axial-lead package. Verify compatibility with the required MIL-PRF-19500/435 qualification level if applicable.
