1N4616-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4616-1/TR is a 500 mW Zener voltage regulator diode with a nominal breakdown voltage of 2.2 V at a test current of 250 µA. It features a maximum dynamic impedance of 1300 Ohms and a maximum reverse leakage current of 1.0 µA. The device operates within a junction temperature range of -65°C to +175°C and utilizes an axial-lead glass DO-35 package.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for enhanced reliability
• Qualified per MIL-PRF-19500/435 standards for high-reliability applications
• Hermetically sealed glass axial-lead packaging

Single Zener Diodes Applications

• Voltage regulation in military-grade electronic systems
• High-reliability circuit protection requiring radiation hardness
• Precision reference voltage generation in harsh environments

Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, JANTXV, or JANS) required for your application, as the base part number covers multiple reliability grades. Confirm RoHS compliance status if environmental regulations apply, noting that commercial versions may differ from mil-qualified units. Ensure the tape and reel suffix matches your automated assembly equipment specifications.

Single Zener Diodes Selection Notes

Select this component when low noise density and stable voltage regulation are critical for low-current circuits. The 2.2 V rating suits applications requiring precise clamping or reference levels below standard logic thresholds. Consider the thermal derating curve for power dissipation limits above 50°C ambient temperature to ensure long-term operational stability.

Single Zener Diodes Part Context

This device belongs to the 1N4614-1 through 1N4627-1 series of 500 mW metallurgically bonded glass Zener diodes. The series offers voltages from 1.8 to 100 V with various tolerance options. The 1N4616-1 specifically addresses the lower end of the voltage spectrum, providing tight regulation characteristics suitable for sensitive analog front-ends.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N4616 variants meeting MIL-PRF-19500/435 specifications. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts match the required reliability grade and electrical parameters such as impedance and leakage current.
