1N5265BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5265BUR-1/TR is a surface mount Zener voltage regulator in the 1N5221BUR-1 series. It features a metallurgically bonded glass DO-213AA (MELF) package with a nominal Zener voltage of 62 V at a test current of 2.0 mA. The device offers a 5% voltage tolerance, a maximum reverse leakage current of 1400 nA, and a dynamic impedance of 185 Ohms. It supports a steady-state power dissipation of 0.5 W and operates within a junction temperature range of -65°C to +175°C.

• High-reliability electronic circuits requiring radiation hardness
• Surface mount equivalents for JEDEC registered axial-leaded diodes

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm RoHS compliance status and tolerance grade. Confirm tape and reel packaging specifications align with manufacturing requirements. Ensure screening references match project reliability standards before procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring a hermetically sealed surface mount Zener diode with high thermal stability. The DO-213AA package provides a direct footprint alternative to traditional axial leads while maintaining robust mechanical integrity and radiation resistance suitable for demanding environments.

Single Zener Diodes Part Context

This part belongs to the 1N5221BUR-1 through 1N5281BUR-1 series of 0.5-watt Zener regulators. The series covers voltages from 2.4 to 200 volts in a metallurgically bonded configuration. It serves as a surface mount equivalent to the widely used JEDEC registered 1N5221 to 1N5281 series.

Single Zener Diodes Replacement Considerations

The 1N5265B is the corresponding axial-leaded version within the same series.
