1N5274-1

Single Zener Diodes Overview

The Microchip Technology 1N5274-1 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 130 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW and utilizes the DO-35 (DO-204AH) glass axial-lead package. It operates within a temperature range of -65 °C to +200 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at 130 V with tight manufacturing tolerances
• Constructed in a hermetically sealed glass axial-lead package for durability
• Capable of handling high operating temperatures up to 200 °C

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 130 V levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation in industrial equipment

Single Zener Diodes Procurement Notes

Verify the specific suffix '-1' confirms the ±5% tolerance variant, as standard 1N5274 parts may differ. Confirm RoHS compliance status, as some Microsemi/Microchip variants are non-compliant. Ensure the DO-35 package matches the PCB footprint requirements. Check for military screening prefixes if environmental ruggedness is required.

Single Zener Diodes Selection Notes

Select this component when a fixed 130 V regulation point is needed with moderate precision. The 500 mW rating suits low-current applications. Consider thermal derating if ambient temperatures approach the upper limit. Verify that the glass axial lead form factor fits the assembly constraints compared to surface-mount alternatives.

Single Zener Diodes Part Context

This part belongs to the popular 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 V to 200 V. These components are widely used in discrete semiconductor designs for basic voltage clamping and reference functions.

Single Zener Diodes Replacement Considerations

The 1N5274-1/TR is a tape-and-reel version of the same electrical specification. Standard 1N5274 parts may have different tolerances or lack the specific suffix designation. Cross-reference with other manufacturers' 130 V 500 mW Zener diodes only if pinout and tolerance specifications match exactly.
