Single Zener Diodes datasheet and documents for 1N5251BTR

1N5251BTR

Single Zener Diodes Overview

The 1N5251BTR is a single Zener diode manufactured by onsemi, formerly Fairchild Semiconductor. It features a nominal Zener voltage of 22 V with a tolerance of ±5%. The device has a maximum power dissipation of 500 mW and operates in the through-hole DO-35-2 package. Key electrical parameters include a maximum reverse leakage current of 100 nA and a Zener impedance of 29 Ohms at a test current of 5.6 mA. The component supports an operating temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

Provides stable voltage regulation at 22 V with high precision tolerance
Designed for through-hole mounting in compact DO-35 packages
Capable of operation across extreme temperature environments up to 200°C

Single Zener Diodes Applications

Voltage reference circuits requiring stable 22 V levels
Overvoltage protection in electronic systems
Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' corresponds to tape-and-reel packaging as specified by the manufacturer. Confirm RoHS compliance status via official datasheets before integration. Ensure the supplier provides traceability documentation matching the onsemi or Fairchild Semiconductor part number history. Validate package dimensions against DO-35 standards during incoming inspection.

Single Zener Diodes Selection Notes

Select this component when a 22 V Zener voltage is required with tight 5% tolerance. Consider the 500 mW power rating for thermal management in the design. The wide temperature range makes it suitable for industrial or automotive environments where standard commercial parts may fail. Verify lead compatibility with existing PCB footprints for DO-35 packages.

Single Zener Diodes Part Context

This part belongs to the 1N5251 series of Zener diodes. Originally produced by Fairchild Semiconductor, the product line is now managed by onsemi following corporate acquisitions. The 1N5251BTR variant specifically denotes the tape-and-reel configuration for automated assembly processes, distinguishing it from bulk-packaged equivalents.
