1N5227B-1

Single Zener Diodes Overview

The Microchip Technology 1N5227B-1 is a Zener diode designed for voltage regulation applications. 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 +175°C. It utilizes a DO-35 glass axial-lead package for through-hole mounting. Key electrical characteristics include a maximum reverse leakage current of 15 µA, a Zener impedance of 24 Ohms at a test current of 20 mA, and a forward voltage of 1.5 V at 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using Zener breakdown in the reverse bias region.
• Constructed with a hermetically sealed glass axial-lead package for environmental protection.
• Capable of operation across an extended industrial temperature range up to 175°C junction temperature.

Single Zener Diodes Procurement Notes

Verify the specific suffix '-1' against official Microchip documentation to confirm military screening requirements or specific lot traceability standards. Ensure the procurement channel provides valid manufacturer authorization. Confirm RoHS compliance status as historical data indicates variations within this series. Validate package dimensions against design constraints before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V regulation point is required with high reliability standards. The DO-35 package suits through-hole designs needing robust mechanical anchoring. Consider the 500 mW power rating for thermal management calculations. Verify that the 24 Ohm impedance meets circuit noise and stability requirements compared to lower impedance alternatives.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener diodes manufactured by Microchip Technology. The series offers a wide selection of voltages from 2.4 V to 200 V. These components are widely used in general-purpose electronics and specialized industrial equipment where consistent voltage regulation is critical for system performance.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5227B variants with identical electrical specifications. Cross-reference with 1N5227BE3 if lead-free compliance is mandatory. Verify pinout compatibility and thermal characteristics when substituting with generic equivalents.
