1N5251B_T50R

Single Zener Diodes Overview

The onsemi 1N5251B_T50R is a single-channel Zener diode with a nominal voltage of 22 V and a power dissipation rating of 500 mW. It features a 5% voltage tolerance and operates within a temperature range of -65 °C to +200 °C. The device utilizes a DO-35 glass axial leaded package for through-hole mounting. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 29 Ohms, and a test current of 5.6 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 22 V level
• Capable of handling up to 500 mW of power dissipation
• Constructed with a hermetically sealed glass axial leaded package

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection stages
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix _T50R against official manufacturer documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure compatibility with automated assembly equipment by checking the supplier's latest mechanical drawing. Confirm RoHS compliance status directly from the datasheet as regulatory requirements may vary by production batch.

Single Zener Diodes Selection Notes

Select this component when a standard 22 V regulation point is required in through-hole designs. The DO-35 package offers robust mechanical stability compared to surface-mount alternatives. Consider the 5% tolerance and 29 Ohm impedance for precision applications requiring moderate accuracy without tight binning requirements.

Single Zener Diodes Part Context

This part belongs to the industry-standard 1N52xx series of 0.5 W Zener diodes. The 'B' suffix typically denotes a 5% voltage tolerance class. The '_T50R' identifier specifies the bulk or reel packaging format used for distribution. This series provides a wide selection of voltages for general electronic circuit design.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N5251B designation in DO-35 packages. Verify that substitute parts meet the same 22 V nominal voltage, 500 mW power rating, and 5% tolerance specifications. Ensure the replacement maintains equivalent thermal and electrical performance characteristics.
