1N5263B_T50A

Single Zener Diodes Overview

The onsemi 1N5263B_T50A is a single-channel Zener diode with a nominal voltage of 56V and a maximum power dissipation of 500 mW. It features a DO-35 through-hole package with a 5% voltage tolerance. The device operates within a temperature range of -65°C to +200°C, has a test current of 2.2 mA, a maximum Zener impedance of 150 Ohms, and a maximum reverse leakage current of 100 nA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation in the reverse breakdown region for circuit protection and reference applications.
• Utilizes a glass axial leaded DO-35 package designed for reliable through-hole mounting.
• Engineered for high thermal stability with an extended operating temperature range up to +200°C.

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific suffix T50A against official datasheets to confirm packaging details such as reel or cut tape specifications. Ensure the manufacturer designation matches onsemi records, as historical data may list Fairchild Semiconductor due to corporate acquisitions. Cross-reference RoHS compliance status with current regulatory documentation before procurement.

Single Zener Diodes Selection Notes

Select this component when a 56V regulation point is required in a through-hole design. The 500 mW rating supports moderate current loads, while the low leakage current ensures minimal standby power consumption. Verify that the 150 Ohm impedance meets the dynamic performance requirements of the target application circuit.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of silicon Zener diodes manufactured by onsemi. These components are widely used in general-purpose electronics for voltage stabilization. The 1N5263B variant specifically targets the 56V segment of the series, offering consistent performance across industrial and commercial temperature ranges.

Single Zener Diodes Replacement Considerations

Equivalent parts include Vishay 1N5263B-TR and generic 1N5263B devices from other manufacturers. Substitutes must match the 56V nominal voltage, 500 mW power rating, and DO-35 package form factor to ensure mechanical and electrical compatibility.
