1N5227BUR

Single Zener Diodes Overview

The 1N5227BUR is a surface-mount Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 3.6 V with a tolerance of ±5%. The device has a maximum power dissipation of 500 mW and operates within a temperature range of -65 °C to +200 °C. It utilizes the DO-213AA (SMB) package and exhibits a maximum reverse leakage current of 15 µA at the rated voltage.

Single Zener Diodes Feature Summary

• Metallurgically bonded glass construction for high reliability
• Surface mount design in DO-213AA package
• Wide operating temperature range up to 200 °C

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection
• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation, as the 1N5227B series is produced by multiple vendors including Central Semiconductor and onsemi. Confirm that the 'BUR' suffix corresponds to the Microchip Technology surface-mount variant in the DO-213AA package. Ensure the required RoHS compliance status matches project specifications, as legacy versions may differ.

Single Zener Diodes Selection Notes

Select this component when a surface-mount Zener diode with a 3.6 V breakdown voltage is required. The 500 mW power rating suits low-current regulation tasks. The wide thermal range supports harsh environments. Verify pinout compatibility with the DO-213AA footprint during PCB layout.

Single Zener Diodes Part Context

This part belongs to the standard 1N5227B Zener diode family, which covers a voltage range from 2.4 V to 200 V. The 'BUR' suffix specifically denotes the surface-mount configuration offered by Microchip Technology, distinguishing it from through-hole axial equivalents.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5227BTR from onsemi and the 1N5227BBK-TL from Central Semiconductor. Verify package type and electrical parameters before substitution.
