1N4622/TR

Single Zener Diodes Overview

The Microchip Technology 1N4622/TR is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3.9V with a tolerance of ±5%. The device has a maximum power dissipation of 500mW and operates within a temperature range of -65°C to +175°C. Packaged in the DO-35 (DO-7) axial leaded format, it exhibits a low reverse leakage current of 5µA at rated voltage.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction suitable for harsh environments
• Low noise performance optimized for sensitive signal circuits
• High thermal stability supporting extended operating temperatures

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Clamping applications in analog signal paths

Single Zener Diodes Procurement Notes

Verify that the specific suffix /TR indicates tape and reel packaging rather than bulk. Confirm RoHS compliance status as historical data suggests potential non-compliance variants. Ensure the supplier provides official Microchip documentation matching the exact part number to avoid confusion with similar 1N4622 series components.

Single Zener Diodes Selection Notes

Select this component when a stable 3.9V reference is required in space-constrained through-hole designs. Consider the 500mW power rating for thermal management. Verify compatibility with existing DO-35 footprints. Evaluate leakage current specifications against circuit sensitivity requirements before finalizing the design.

Single Zener Diodes Part Context

This component belongs to the standard 1N4622 series of low-power Zener diodes manufactured by Microchip Technology. It shares the electrical characteristics of the military-grade JAN1N4622C but utilizes commercial packaging. The series is widely recognized for reliable voltage regulation in industrial and aerospace electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes include the 1N4622 without the /TR suffix for bulk packaging needs. Cross-reference with JAN1N4622C for hermetic sealing requirements. Verify pinout and package dimensions match DO-35 standards before integration.
