1N969B/TR

Single Zener Diodes Overview

The Microchip Technology 1N969B/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 22 V with a tight tolerance of 5%. The device operates in the DO-213AA-2 (SMA) surface-mount package and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 500 nA, a Zener impedance of 29 Ohms at a test current of 5.6 mA, and an operating temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal 22 V breakdown voltage.
• Engineered for surface-mount assembly using the compact DO-213AA-2 package.
• Capable of reliable operation across an extended industrial temperature range.

Single Zener Diodes Applications

• Precision voltage reference circuits
• Over-voltage protection stages
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix TR indicates reel packaging when sourcing. Confirm the DO-213AA-2 footprint compatibility with your PCB design. Ensure the 5% voltage tolerance meets your circuit requirements. Check RoHS status if environmental compliance is mandatory for your project specifications.

Single Zener Diodes Selection Notes

Select this component when a 22 V regulation point is required in a surface-mount form factor. The 500 mW power rating suits low-current applications. Consider the 29 Ohm impedance for noise-sensitive designs. Verify that the 500 nA leakage current fits your high-impedance input constraints.

Single Zener Diodes Part Context

This part belongs to the standard Zener diode family manufactured by Microchip Technology. It utilizes the DO-213AA-2 package, commonly known as SMA, which is distinct from through-hole axial variants like the JAN1N969B-1. The device serves as a fundamental passive component for establishing fixed potential levels in electronic systems.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 22 V Zener voltage, 500 mW power dissipation, DO-213AA-2 package, and 5% tolerance specifications.
