1N5263B-T50R

Single Zener Diodes Overview

The onsemi 1N5263B-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 dissipates up to 500 mW and operates within a temperature range of -65°C to +200°C. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 150 Ohms, and a test current of 2.2 mA. It utilizes a DO-35 axial leaded package.

Single Zener Diodes Feature Summary

• Provides stable voltage reference capabilities through precise Zener breakdown characteristics.
• Engineered for high thermal stability across an extended operating temperature range.
• Features low reverse leakage current to minimize power loss in standby states.

Single Zener Diodes Applications

• Voltage stabilization circuits
• Overvoltage protection systems
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official datasheets. Confirm RoHS compliance status and specific packaging details such as reel or cut tape configuration prior to ordering. Ensure the supplier provides traceable documentation matching the exact suffix specifications.

Single Zener Diodes Selection Notes

Select this component when a 56 V regulation point is required in through-hole designs. Consider the 500 mW power dissipation limit and the specific DO-35 package dimensions for board layout compatibility. Evaluate the 150 Ohm impedance against circuit sensitivity requirements.

Single Zener Diodes Part Context

This component belongs to the standard 1N5263 series of Zener diodes manufactured by onsemi. It represents a legacy axial-leaded variant often utilized in robust industrial and commercial electronics where through-hole mounting is preferred for mechanical durability.

Single Zener Diodes Replacement Considerations

Equivalent parts include Vishay 1N5263B-TR and Microchip 1N5263BUR-1/TR. Verify package type differences, as some equivalents utilize surface-mount MELF packages instead of the axial DO-35 form factor.
