1N5231B_T50A

Single Zener Diodes Overview

The onsemi 1N5231B_T50A is a single-channel general-purpose Zener diode with a nominal voltage of 5.1 V and a maximum power dissipation of 500 mW. It features a 2% tolerance, operates within a temperature range of -65°C to 200°C, and utilizes an SOD-27 through-hole package. Key electrical parameters include a test current of 20 mA, a maximum Zener impedance of 17 Ω, and a maximum reverse leakage current of 5 μA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 5.1 V level for circuit protection and reference applications.
• Operates reliably across an extended industrial temperature range from -65°C to 200°C.
• Features low reverse leakage current to minimize standby power consumption in sensitive designs.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 5.1 V levels
• Overvoltage protection in signal conditioning paths
• General-purpose clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify the specific suffix _T50A against official datasheets to confirm packaging details and compliance status. Ensure compatibility with existing thermal management strategies given the 500 mW dissipation limit. Cross-reference pinout configurations if substituting from other manufacturers to prevent assembly errors.

Single Zener Diodes Selection Notes

Select this component when a tight 2% voltage tolerance is required compared to standard 5% variants. The SOD-27 through-hole package offers mechanical stability for high-reliability environments. Consider the 200°C maximum operating temperature for high-heat applications where standard silicon limits may be exceeded.

Single Zener Diodes Part Context

This part belongs to the 1N52 series of Zener diodes, widely used for basic voltage regulation. The 1N5231B designation specifically indicates the 5.1 V variant. The T50A suffix typically denotes specific tape-and-reel or bulk packaging configurations defined by onsemi for automated assembly processes.

Single Zener Diodes Replacement Considerations

Direct substitutes include Vishay 1N5231B and Microchip 1N5231B. Verify that replacement parts match the 2% tolerance and SOD-27 package dimensions to ensure fit and functional equivalence without redesigning the PCB footprint.
