1N5276B-1E3

Single Zener Diodes Overview

The Microchip Technology 1N5276B-1E3 is a single Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 150 V with a tight tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW and utilizes the DO-204AH (DO-35) axial through-hole package. Key electrical characteristics include a maximum reverse leakage current of 100 nA at 108 V and a maximum Zener impedance of 1500 Ohms. It supports a junction temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal breakdown voltage of 150 V.
• Ensures high precision performance with a strict ±5% voltage tolerance.
• Capable of operating reliably in extreme thermal environments up to 175°C junction temperature.
• Offers low reverse leakage current to minimize standby power loss.

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• High-voltage regulator designs

Single Zener Diodes Procurement Notes

Verify that the specific suffix 'E3' confirms lead-free compliance and RoHS status, as standard variants may differ. Confirm the package type matches the required PCB footprint. Check for any recent Product Change Notifications regarding assembly sites or labeling changes. Ensure the supplier provides valid traceability documentation for aerospace or defense contracts if applicable.

Single Zener Diodes Selection Notes

Select this component when a precise 150 V reference is required with tighter tolerance than standard ±10% versions. The E3 suffix indicates environmental compliance, which is critical for regulated markets. Consider the 1500 Ohm impedance for noise sensitivity in the application. Verify that the 500 mW power rating suits the expected current levels in the circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of glass-passivated Zener diodes manufactured by Microchip Technology. These components are widely used in industrial and military-grade electronics due to their robust construction and wide operating temperature range. The 1N5276B-1E3 specifically denotes the 150 V variant within this family, distinguished by its 5% tolerance and lead-free manufacturing process.

Single Zener Diodes Replacement Considerations

The 1N5276B is the non-E3 equivalent with identical electrical specifications but potentially different environmental compliance. The 1N5276A offers the same 150 V rating but with a wider ±10% tolerance. Ensure substitute parts match the DO-204AH package dimensions and thermal characteristics.
