1N5262B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5262B/TR is a 500 mW glass axial-lead Zener diode housed in the DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 51 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse current of 100 µA at 39 V. Electrical characteristics include a Zener impedance of 125 Ohms at a test current of 2.5 mA and a forward voltage of 1.5 V maximum at 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Inherently radiation hard per MicroNote 050
• Minimal capacitance characteristics suitable for high-frequency circuits

Single Zener Diodes Applications

• Voltage reference circuits requiring precise regulation
• Overvoltage protection in electronic systems
• General-purpose voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'TR' suffix indicates tape and reel packaging compliant with EIA-296 standards. Confirm RoHS compliance status if applicable, as it may require an additional 'e3' suffix. Ensure the component meets specific military screening requirements if necessary, which involve adding prefixes such as MQ or MX to the part number.

Single Zener Diodes Selection Notes

Select this component when a 51 V Zener voltage with tight ±5% tolerance is required. The DO-35 package offers standard axial leads for easy integration into printed circuit boards. Consider the thermal resistance and power derating curves for high-temperature environments. Verify that the maximum reverse current and impedance values align with the circuit's leakage and stability requirements.

Single Zener Diodes Part Context

This part belongs to the popular 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators. The series covers a wide selection of voltages from 2.4 to 200 volts. These devices are JEDEC registered and offer various tolerance options identified by suffix letters. The 1N5262B specifically targets applications needing a 51 V breakdown voltage with enhanced precision compared to standard tolerances.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5262A for 10% tolerance or 1N5262C/D for tighter tolerances. Surface mount equivalents are available in the MLL5221 to MLL5281B series using the DO-213AA MELF package. DO-7 glass body axial-leaded equivalents are also offered by the manufacturer.
