MMSZ5267B-HE3_A-08

Single Zener Diodes Overview

The MMSZ5267B-HE3_A-08 is a silicon planar Zener diode in the SOD-123 package, rated for a nominal voltage of 75 V with a ±5% tolerance. It operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 500 mW at thermal equilibrium. The device is AEC-Q101 qualified, offering an ESD capability exceeding 8 kV via the human body model and over 800 V via the machine model.

Single Zener Diodes Feature Summary

AEC-Q101 qualified automotive-grade reliability
High electrostatic discharge protection performance
RoHS-compliant construction

Single Zener Diodes Applications

Automotive electronic circuit protection
Voltage reference applications
General-purpose small signal regulation

Single Zener Diodes Procurement Notes

Verify that the ordering suffix HE3_A-08 corresponds to the specific AEC-Q101 qualified variant. Confirm the B suffix indicates the standard ±5% tolerance rather than the tighter C tolerance. Ensure the component matches the required SOD-123 footprint and lead configuration for the target assembly process.

Single Zener Diodes Selection Notes

Select this component when a 75 V Zener voltage with moderate tolerance is required in a compact surface-mount form factor. The HE3_A suffix ensures compliance with automotive qualification standards. Evaluate the maximum power dissipation limits against the expected ambient operating temperatures to ensure safe thermal operation.

Single Zener Diodes Part Context

This part belongs to the Vishay MMSZ5225 to MMSZ5267 series of small signal Zener diodes. The series provides a wide range of nominal voltages from 3.0 V to 75 V in the SOD-123 package. The HE3_A suffix denotes RoHS compliance combined with AEC-Q101 qualification, distinguishing it from commercial grade equivalents.
