1N5274B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5274B/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 package, featuring a nominal voltage of 130 V with ±5% tolerance (suffix B). It operates within a temperature range of -65°C to +175°C and includes a tape-and-reel option indicated by the TR suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Hermetically sealed glass axial-lead construction for durability
• Inherently radiation hard per MicroNote 050
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the part number includes the 'TR' suffix to confirm tape-and-reel packaging. Ensure the 'e3' suffix is present if RoHS compliance is required. Confirm the 'B' suffix indicates the standard 5% voltage tolerance. Check manufacturer documentation for specific military screening prefixes if applicable.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 130 V reference with tight 5% tolerance. The DO-35 package suits through-hole designs. Consider thermal derating curves for power dissipation limits above 25°C ambient temperature. Verify lead length requirements for accurate electrical testing.

Single Zener Diodes Part Context

This device belongs to the 1N5221–1N5281B series of 0.5 W Zener Voltage Regulators. The series offers voltages from 2.4 V to 200 V. The 'B' suffix denotes a standard 5% tolerance, while other suffixes indicate tighter tolerances or different configurations.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5274 and 1N5274A. Verify compatibility regarding voltage tolerance and package type before substitution.
