1N5262B_T50R

Single Zener Diodes Overview

The onsemi 1N5262B_T50R is a single-channel Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 51 V with a tolerance of ±5%. The device operates in the DO-35 axial through-hole package, dissipating up to 500 mW of power. Key electrical parameters include a maximum reverse leakage current of 100 nA and a Zener impedance of 125 Ohms at a test current of 2.5 mA. It supports an operating temperature range from -65 °C to +200 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using double slug type construction within a hermetically sealed glass package.

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and lead condition prior to assembly. Ensure storage conditions comply with moisture sensitivity level requirements to prevent solderability issues during reflow or wave soldering processes.

Single Zener Diodes Selection Notes

Select this component when a precise 51 V regulation point is required in through-hole designs. Consider the 5% tolerance and 125 Ohm impedance for circuit stability. Evaluate thermal management needs as the device handles 500 mW dissipation. Compare against surface mount alternatives if board space is constrained.

Single Zener Diodes Part Context

This part belongs to the 1N5262 series of 500 mW Zener diodes manufactured by onsemi. It utilizes the standard DO-35 (DO-204AH) glass axial package. The suffix _T50R indicates specific tape and reel packaging configuration for automated insertion equipment.

Single Zener Diodes Replacement Considerations

Cross-reference with Vishay 1N5262B-TR or Microchip 1N5262B/TR for equivalent electrical characteristics. Verify pinout compatibility and package dimensions before substitution. Check manufacturer obsolescence notices for long-term supply chain stability.
