1N5265A

Single Zener Diodes Overview

The Microchip Technology 1N5265A is a single Zener diode housed in a DO-35 glass axial-lead package. It provides a nominal Zener voltage of 62 V with a standard tolerance of ±10%. The device dissipates up to 500 mW at 25°C and operates within a temperature range of -65°C to +175°C. Key electrical parameters include a maximum reverse current of 1400 µA, a Zener impedance of 185 Ohms at a test current of 2.0 mA, and a positive voltage temperature coefficient of +0.097 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features minimal capacitance characteristics suitable for high-frequency applications
• Constructed with a hermetically sealed glass body for environmental protection
• Inherently radiation hard per MicroNote 050 specifications

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• Clamping applications for transient suppression

Single Zener Diodes Procurement Notes

Verify the specific suffix letter (e.g., A or B) to confirm the required voltage tolerance level before procurement. Confirm that the ordering suffix matches the desired packaging format, such as bulk or tape and reel options. Ensure compatibility with RoHS compliance requirements if applicable by checking for the e3 designation on the component marking.

Single Zener Diodes Selection Notes

Select this component when a 62 V breakdown voltage is required in an axial-lead form factor. Consider the positive temperature coefficient for thermal stability analysis in the target circuit design. Evaluate the power dissipation limits against the expected load current to ensure operation remains within the safe derating curve provided in the datasheet.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 2.4 V to 200 V in the standard DO-35 glass package. These devices are JEDEC registered and widely used in general-purpose regulation tasks.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other 1N52xx variants with different voltage ratings. Surface mount equivalents are available in the MLL5221 to MLL5281B series using the DO-213AA MELF package. Military screening levels can be obtained by adding specific prefixes to parts with the -1 suffix.
