1N4615UR-1

Single Zener Diodes Overview

The Microchip Technology 1N4615UR-1 is a 500 mW Zener voltage regulator in the surface mount glass DO-213AA package. It features an internal metallurgical bond and is qualified per MIL-PRF-19500/435 for JAN, JANTX, JANTXV, and JANS levels. The nominal Zener voltage is 2 V at a test current of 250 µA. Maximum Zener impedance is 1250 Ohms, with a maximum reverse current of 1 µA. Noise density is 1 µV/√Hz, and the temperature coefficient is -0.075 %/°C.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for high reliability
• Hermetically sealed glass DO-213AA surface mount package
• Qualified to military standards including JANS level

Single Zener Diodes Applications

• Voltage regulation over broad ranges of current and temperature
• High reliability applications requiring radiation hardness
• ESD non-sensitive circuits per MIL-STD-750 method 1020

Single Zener Diodes Procurement Notes

Verify the specific reliability level (JAN, JANTX, JANTXV, or JANS) required for the application when ordering. Confirm RoHS compliance status, as commercial versions may differ from military qualifications. Ensure the metallurgically bonded suffix (-1) is included if specified. Check datasheet for thermal derating requirements above 25°C ambient temperature.

Single Zener Diodes Selection Notes

Select this component for low-voltage Zener regulation where hermetic sealing and radiation hardness are critical. The DO-213AA package provides a surface mount equivalent to axial-leaded types. Consider the negative temperature coefficient for low-voltage designs. Verify that the 500 mW power dissipation rating meets the circuit's thermal requirements under operating conditions.

Single Zener Diodes Part Context

This device belongs to the 1N4614UR-1 through 1N4627UR-1 series of 500 mW metallurgically bonded glass surface mount Zener diodes. The series covers voltages from 1.8 to 100 V with standard 5% tolerance. It serves as the surface mount counterpart to JEDEC registered axial-leaded 1N4614 through 1N4627 series devices.

Single Zener Diodes Replacement Considerations

The CDLL4615-1 is a commercially available equivalent within the same metallurgically bonded series. Axial-leaded 1N4615 devices are mechanical equivalents but lack the surface mount form factor.
