1N4616

Single Zener Diodes Overview

The Microchip Technology 1N4616 is a silicon unidirectional voltage regulator diode designed for low current operation. It features a nominal Zener voltage of 2.2 V with a test current of 250 µA and a maximum Zener impedance of 1.25 kΩ. The device operates within an ambient temperature range of -65°C to +175°C and supports a DC power dissipation of 500 mW at +50°C, with a derating factor of 4 mW/°C above this threshold. It utilizes a DO-7 package.

Single Zener Diodes Feature Summary

• Double plug construction for enhanced reliability
• Metallurgically bonded internal structure

Single Zener Diodes Applications

• Voltage regulation in military systems
• Reference voltage sources in aerospace electronics
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, JANTXV, or JANS) required for your application, as these levels dictate the manufacturing standards under MIL-PRF-19500/435. Confirm that the DO-7 axial leaded package matches your PCB layout constraints. Ensure compliance with environmental regulations if RoHS exemptions are necessary for defense contracts.

Single Zener Diodes Selection Notes

Select this component when a stable 2.2 V reference is needed in extreme thermal environments up to 175°C. The low test current of 250 µA makes it efficient for battery-powered or low-power signal conditioning circuits. Consider the metallurgical bond construction for superior vibration resistance compared to standard commercial diodes.

Single Zener Diodes Part Context

This part belongs to the 1N4614 through 1N4627 series of 500 mW Zener diodes. These components are widely used in high-reliability sectors where consistent performance under harsh conditions is mandatory. The series offers various tolerance options and qualification levels to meet diverse military and aerospace specifications.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4616 equivalents meeting MIL-PRF-19500/435 standards. Verify pinout compatibility and ensure the replacement maintains the same 2.2 V Zener voltage and 500 mW power rating.
