1N5251B-TP

Single Zener Diodes Overview

The MCC 1N5251B-TP is a 0.5W Zener diode with a nominal voltage of 22V and ±5% tolerance. It operates in the -55°C to +150°C range within a DO-35 glass package. Key electrical parameters include a maximum reverse leakage current of 0.1µA at 17V, a test current of 5.6mA, and a Zener impedance of 29Ω. The device features a positive temperature coefficient of +0.087%/°C and supports high-temperature soldering at 260°C for 10 seconds.

Single Zener Diodes Feature Summary

• Utilizes a hermetically sealed glass axial-leaded DO-35 package for environmental stability.
• Supports high-temperature soldering processes up to 260°C for ten seconds at terminals.
• Provides stable voltage regulation across an extended industrial operating temperature range.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in power supplies
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify authenticity by purchasing only from authorized distributors or directly from Micro Commercial Components. Counterfeit parts are prevalent; unauthorized sources lack traceability and quality assurance. Confirm the specific suffix matches required packaging before ordering.

Single Zener Diodes Selection Notes

Select this component for through-hole designs needing precise 22V regulation. Ensure circuit current limits stay below the 500mW dissipation rating. Consider derating requirements above 50°C when calculating thermal performance in enclosed environments.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series of 0.5W Zener regulators. The 'B' suffix indicates a standard 5% voltage tolerance. The '-TP' suffix designates Tape & Reel packaging containing 10,000 pieces per reel.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N5251B designation. Verify that replacement parts match the DO-35 footprint, 500mW power rating, and 22V nominal voltage specifications.

Single Zener Diodes FAQ

What does the 'B' suffix indicate?
