1N5258B_T50R

Single Zener Diodes Overview

The onsemi 1N5258B_T50R is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 56 V with a tolerance of ±5%. The device operates in a DO-35-2 through-hole package and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 150 Ohms, and a test current of 2.2 mA. It supports an operating temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single unidirectional Zener junction.
• Constructed with a hermetically sealed glass axial leaded package for environmental resistance.
• Engineered for high thermal stability with an extended operating temperature range.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages in electronic systems.
• Clamping applications within signal processing paths.

Single Zener Diodes Procurement Notes

Verify the specific suffix T50R against official datasheets to confirm reel packaging specifications. Confirm RoHS compliance status directly with manufacturer documentation prior to integration. Ensure the DO-35-2 footprint matches the target PCB layout requirements. Validate that the 56 V rating aligns with the circuit design constraints.

Single Zener Diodes Selection Notes

Select this component when a 56 V regulation point is required with tight tolerance accuracy. The DO-35 package suits through-hole assembly processes. Consider the 150 Ohm impedance value for dynamic load regulation needs. Verify that the 500 mW power dissipation capability meets the thermal management requirements of the application environment.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of Zener diodes manufactured by onsemi. The series offers various voltage options within the same mechanical form factor. The 1N5258B designation specifically identifies the 56 V variant with B-grade tolerance. The T50R suffix indicates the specific tape and reel packaging configuration for automated insertion.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N5258B equivalents in DO-35 packages. Ensure substitute parts match the 56 V nominal voltage and ±5% tolerance. Verify that alternative components support the same 500 mW power dissipation and operating temperature range.
