1N5272

Single Zener Diodes Overview

The Microchip Technology 1N5272 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 110 V with a standard tolerance of 5%. The device operates in a DO-35-2 through-hole package and supports a power dissipation of 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. The component maintains functionality across an extended temperature range from -65°C to +175°C.

Single Zener Diodes Procurement Notes

Verify the specific suffix letter (e.g., A, B) associated with the part number to confirm the exact voltage tolerance and screening level required for the application. Confirm that the DO-35-2 through-hole package aligns with the target PCB layout. Ensure the selected variant meets any necessary military or industrial reliability standards if applicable to the design specifications.

Single Zener Diodes Selection Notes

Select this component when a 110 V regulation point is needed within a low-power constraint. The 500 mW rating suits applications where heat dissipation is manageable without additional cooling. Consider the 750 Ohm impedance value for circuit stability requirements. Verify that the through-hole mounting style fits the assembly process constraints compared to surface-mount alternatives.

Single Zener Diodes Part Context

This device belongs to the widely recognized 1N5221 through 1N5281 series of 0.5-watt Zener voltage regulators. The series offers a broad selection of voltages ranging from 2.4 to 200 volts. These components are standard JEDEC registered parts available in various tolerance grades and screening levels, making them common choices for general electronic designs.

Single Zener Diodes Replacement Considerations

Equivalent devices include the CD5272B die for surface mount conversion and the MV1N5272A hermetically sealed variant. Surface mount equivalents such as the 1N5267BUR-1 series provide similar performance in different packages.
