1N5265B

Single Zener Diodes Overview

The Microchip Technology 1N5265B is a single Zener diode with a nominal voltage of 62 V and a maximum power dissipation of 500 mW. It features a ±5% tolerance, indicated by the 'B' suffix, and operates within a temperature range of -65°C to +175°C. The device utilizes a DO-35 (DO-204AH) glass axial-lead package. Electrical characteristics include a maximum reverse current of 100 µA at 47 V and a maximum Zener impedance of 185 Ohms at a test current of 2.0 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 suitable for high-frequency circuits

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Voltage regulator designs

Single Zener Diodes Procurement Notes

Verify that the component matches the specific JEDEC registered type number and tolerance requirements. Confirm RoHS compliance status if required, as standard versions may differ from e3 suffix variants. Ensure the supplier provides documentation confirming the hermetically sealed glass package and correct polarity banding for proper installation.

Single Zener Diodes Selection Notes

Select this component when a precise 62 V regulation point is needed with tight ±5% tolerance. Consider the thermal resistance and derating curves for high-temperature environments. Verify that the low capacitance and radiation hardness align with the specific environmental constraints of the target application.

Single Zener Diodes Part Context

This part belongs to the popular 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 to 200 volts in standard tolerances. These devices are manufactured by Microsemi's Scottsdale Division and are widely used in general-purpose electronic circuits requiring reliable voltage clamping or referencing.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5264B (60V) and 1N5266B (68V). Surface mount equivalents are available in the MLL5221 to MLL5281B MELF style package. Military screening levels can be obtained using MQ, MX, MV, or MSP prefixes.
