1N5265A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5265A/TR is a single silicon Zener diode with a nominal voltage of 62 V and a 10% tolerance. It operates in the DO-35 (DO-204AH) glass axial-lead package, dissipating up to 500 mW at 25°C. The device features a maximum reverse leakage current of 100 nA at 900 mV and a dynamic impedance of 185 Ohms at a test current of 2.0 mA. It supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features hermetically sealed glass axial-lead construction for environmental durability
• Offers minimal capacitance characteristics suitable for high-frequency applications
• Inherently radiation hard per MicroNote 050 specifications

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the tape and reel packaging format as specified in the datasheet. Confirm the component meets RoHS compliance requirements by checking for the 'e3' suffix designation on the physical marking or official documentation. Ensure the procurement specification aligns with the standard JEDEC registration parameters for this series.

Single Zener Diodes Selection Notes

Select this component when a 62 V breakdown voltage with 10% tolerance is required in a through-hole axial configuration. The 500 mW power rating defines the thermal limits for steady-state operation. Consider the specific dynamic impedance and leakage current values for precision circuit design. Verify that the DO-35 package dimensions fit the target PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators manufactured by Microsemi's Scottsdale Division. The series provides a wide selection of voltages from 2.4 V to 200 V in standard DO-35 packages. The 1N5265A variant specifically addresses the 62 V segment of this extensive lineup.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the MLL5221 to MLL5281B series using the DO-213AA MELF package. Other variants within the 1N5221-1N5281B family may be considered if different voltage ratings or tighter tolerances are needed.
