1N4615-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4615-1/TR is a 2.0 V Zener diode in the 1N4614-1 through 1N4627-1 series, housed in an axial-lead glass DO-35 package. It features an internal metallurgical bond and operates within a temperature range of -65°C to +175°C. The device provides a nominal Zener voltage of 2.0 V at a test current of 250 µA, with a maximum dynamic impedance of 1250 Ohms and a reverse leakage current of 2.5 µA. Rated for 500 mW power dissipation, it offers a tight voltage tolerance of 5% and a negative temperature coefficient of -0.075 %/°C.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for enhanced reliability
• Hermetically sealed glass DO-35 axial-lead package
• Low noise density performance suitable for precision applications
• Inherently radiation hard design

Single Zener Diodes Applications

• Voltage regulation over broad ranges of current and temperature
• High-reliability military and aerospace circuits
• Precision reference voltage generation

Single Zener Diodes Procurement Notes

Verify that the TR suffix indicates tape and reel packaging per EIA-296 standards. Confirm the specific reliability level (commercial, JAN, JANTX, JANTXV, or JANS) required for the application, as qualification levels vary across the product family. Ensure compatibility with MIL-STD-750 soldering methods if high-reliability grades are selected.

Single Zener Diodes Selection Notes

Select this component for applications requiring low-voltage regulation with strict tolerance requirements. The internal metallurgical bond distinguishes it from non-bonded variants. Consider the negative temperature coefficient when designing for wide thermal operating ranges. Verify that the 5% standard tolerance meets circuit specifications before choosing tighter tolerance options like 2% or 1%.

Single Zener Diodes Part Context

This part belongs to the 1N4614-1 through 1N4627-1 series of 500 mW metallurgically bonded glass Zener diodes. The series covers voltages from 1.8 V to 100 V and is JEDEC registered. It is available in multiple packages including DO-35, DO-213AA, and DO-216, with various military qualification levels available.

Single Zener Diodes Replacement Considerations

Non-bonded equivalents exist without the "-1" suffix. Surface mount alternatives include the 1N4614UR-1 through 1N4627UR-1 series in DO-213AA packages.
