1N4615-1

Single Zener Diodes Overview

The Microchip Technology 1N4615-1 is a 2.0 V Zener voltage regulator featuring an internal metallurgical bond within a hermetically sealed axial-lead glass DO-35 package. It operates with a test current of 250 µA and exhibits a maximum dynamic impedance of 1250 Ohms at this bias point. The device maintains a reverse leakage current of no more than 2.5 µA and supports a rated average power dissipation of 0.5 W. It functions reliably across a junction temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for enhanced structural integrity
• Hermetically sealed glass DO-35 axial-lead package design
• Qualified per MIL-PRF-19500/435 for high reliability applications

Single Zener Diodes Applications

• High-reliability circuit protection requiring radiation hardness
• Precision reference voltage generation in harsh environments

Single Zener Diodes Procurement Notes

Verify the specific qualification level required, as the base part number covers JAN, JANTX, JANTXV, and JANS variants. Confirm RoHS compliance status if applicable, noting that commercial versions may differ from military-qualified units. Ensure ordering suffixes match the desired tolerance and packaging specifications defined in the manufacturer's nomenclature guide.

Single Zener Diodes Selection Notes

Select this component when a low-voltage reference requires strict thermal stability and long-term reliability. The negative temperature coefficient makes it suitable for specific compensation networks. Verify that the 1250 Ohm impedance meets the noise and regulation requirements of the target application compared to lower-impedance alternatives.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N4614 through 1N4627 series of 500 mW Zener diodes. The series provides voltages ranging from 1.8 V to 100 V in standard 5% tolerances. These regulators are designed for demanding environments where hermetic sealing and metallurgical bonding are critical for performance longevity.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1N4615-1 instances from qualified manufacturers adhering to MIL-PRF-19500/435. Surface mount equivalents exist in the DO-213AA package format, such as the 1N4615UR-1 variant, provided mechanical constraints allow.
