1N5274BE3

Single Zener Diodes Overview

The Microchip Technology 1N5274BE3 is a hermetically sealed glass axial-lead Zener diode in the DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 130 V with a standard tolerance of ±5%, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +175°C and dissipates up to 0.5 watts at 25°C. Electrical characteristics include a maximum reverse current of 94 µA, a Zener impedance of 1100 Ohms at a test current of 0.95 mA, and a positive temperature coefficient of +0.110 %/°C.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'e3' confirms RoHS compliance as specified in the datasheet features. Confirm the 'B' suffix corresponds to the required ±5% voltage tolerance. Ensure the procurement specification matches the DO-35 glass package dimensions and lead configuration. Cross-reference the manufacturer part number against the official Microsemi/Microchip database to validate authenticity.

Single Zener Diodes Selection Notes

Select this component when a stable 130 V reference is required in high-temperature applications up to 175°C. The ±5% tolerance suits general regulation needs where tighter precision is unnecessary. Consider the positive temperature coefficient for thermal compensation requirements. Verify that the 0.5 W power dissipation rating aligns with the circuit's thermal design and derating curves.

Single Zener Diodes Part Context

This device belongs to the JEDEC registered 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators. The series offers a wide selection from 2.4 to 200 volts. The 'e3' suffix denotes RoHS compliant devices available within this family. These components are designed for flexible axial-lead mounting and provide reliable performance in various electronic systems.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5274A (10% tolerance) or 1N5274C/D (tighter tolerances). Military screening levels are available via prefixes such as MQ, MX, MV, or MSP combined with the '-1' suffix.
