JAN1N4621D-1/TR

Single Zener Diodes Overview

The JAN1N4621D-1/TR is a silicon unidirectional Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 3.6V with a tolerance of 1%. The device is rated for a maximum power dissipation of 0.5W and operates within an extended temperature range from -65°C to +175°C. It utilizes a DO-35 axial leaded package, also designated as DO-7, containing two pins. The component exhibits a maximum dynamic impedance of 1700 ohms and is metallurgically bonded. It complies with MIL-PRF-19500/435 standards for military-grade reliability.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with 1% tolerance at a 3.6V nominal level.
• Engineered for extreme environmental stability across a wide operating temperature range.
• Constructed with metallurgical bonding in a rugged axial glass-passivated package.

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm tape-and-reel packaging versus bulk supply. Ensure compliance requirements match project specifications, as this component may not meet RoHS directives. Confirm that the MIL-PRF-19500/435 qualification status aligns with procurement contracts. Validate the package type and pin configuration during incoming inspection.

Single Zener Diodes Selection Notes

Select this component when a stable 3.6V reference is required under extreme thermal conditions. The low leakage current and high impedance characteristics suit sensitive analog front ends. Consider the axial package constraints for PCB layout. Compare dynamic impedance values against load regulation requirements to ensure signal integrity in noise-sensitive applications.

Single Zener Diodes Part Context

This part belongs to the JAN series of radiation-hardened or high-reliability discrete semiconductors produced by Microchip Technology. The JAN prefix indicates adherence to strict military quality standards. It is functionally related to the standard 1N4621 series but offers enhanced performance metrics and material consistency for defense and space applications.
