1N5272BE3

Single Zener Diodes Overview

The Microchip Technology 1N5272BE3 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 110 V with a tolerance of 5%. The device operates in a DO-35-2 through-hole package and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 750 Ohms at a test current of 1.1 mA, and a forward voltage of 1.5 V. It supports an operating temperature range from -65 C to +175 C.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' indicates lead-free compliance when sourcing. Confirm the package type matches the required PCB footprint. Ensure the supplier provides official datasheets to validate the 110 V rating and 500 mW power dissipation limits against design requirements.

Single Zener Diodes Selection Notes

Select this component for designs requiring a precise 110 V reference point. Consider the 750 Ohm impedance for noise sensitivity. Verify that the circuit current stays within the 500 mW thermal limit. Check if the standard 5% tolerance meets the system accuracy needs without additional trimming.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of 0.5 W Zener diodes manufactured by Microchip Technology. These components are widely used in industrial and commercial electronics for basic voltage clamping and reference tasks. The BE3 designation typically denotes environmental compliance and specific manufacturing lot tracking.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 110 V, 500 mW Zener diodes in the DO-35 package. Verify pinout compatibility and thermal resistance values before substitution.
