1N5224B-1

Single Zener Diodes Overview

The Microchip Technology 1N5224B-1 is a hermetically sealed, unidirectional silicon Zener diode housed in the DO-35 (DO-204AH) glass axial-lead package. It provides a nominal reference voltage of 2.8 V with a maximum dynamic impedance of 30 Ω at a test current of 20 mA. The device supports a maximum power dissipation of 0.5 W and maintains a voltage tolerance of 5%. It operates within a temperature range up to 200 °C.

Single Zener Diodes Feature Summary

Hermetically sealed glass construction for corrosion resistance
Compression bonded internal bonds for reliability
Industry-standard JEDEC registered DO-35 package

Single Zener Diodes Applications

Precision voltage regulation circuits
Overvoltage protection systems
Reference voltage sources in instrumentation

Single Zener Diodes Procurement Notes

Verify the specific suffix '-1' indicates internal bond options when sourcing from distributors. Confirm RoHS compliance status as legacy military variants may differ from commercial equivalents. Ensure the supplier provides traceability documentation if the application requires adherence to MIL-PRF-19500 screening levels associated with this part family.

Single Zener Diodes Selection Notes

Select this component when hermetic sealing and high reliability are required over standard commercial plastic packages. The DO-35 form factor suits through-hole mounting constraints. Verify that the 2.8 V nominal voltage aligns with circuit requirements, noting that tighter tolerances may require different suffix designations within the same series.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers voltages from 2.4 V to 200 V. The '-1' suffix specifically denotes internal bond availability, distinguishing it from standard commercial versions while maintaining the core electrical characteristics of the 1N5224B specification.
