1N5261B_T50R

Single Zener Diodes Overview

The onsemi 1N5261B_T50R is a single-channel Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 47 V with a tolerance of ±5%. The device operates in the DO-35 through-hole package and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 105 Ohms at a test current of 2.7 mA, and a voltage temperature coefficient of 0.1%/K. It supports an operating temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using silicon planar technology within a glass passivated junction.
• Offers tight voltage tolerance of ±5% for precision circuit requirements.
• Features low dynamic impedance to maintain consistent performance under varying load conditions.

Single Zener Diodes Applications

• General-purpose voltage reference circuits
• Overvoltage protection stages
• Biasing networks in analog signal processing

Single Zener Diodes Procurement Notes

Verify the specific suffix T50R against official datasheets to confirm reel packaging specifications. Confirm RoHS compliance status directly with the manufacturer documentation as regulatory details may vary by production batch. Ensure the DO-35 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 47 V regulation point is required with high thermal stability. The low leakage current makes it suitable for sensitive measurement circuits. Compare the 105 Ohm impedance against other series members if lower noise or tighter regulation is needed for the specific application environment.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xxB series of axial-leaded Zener diodes manufactured by onsemi. The series covers a wide voltage range from 2.4 V to higher values, all sharing the same 500 mW power dissipation capability in the DO-35 glass package. The 'B' suffix indicates the ±5% voltage tolerance class.

Single Zener Diodes Replacement Considerations

Cross-reference with Vishay 1N5261B-TR for identical electrical characteristics. Other manufacturers producing 1N5261B variants in DO-35 packages may serve as functional substitutes if pinout and thermal ratings align.
