AZ23C3V9-HE3_A-18

Overview

The AZ23C3V9-HE3_A-18 is a dual common anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 3.9 V with a standard tolerance of ±5%. The device operates within a junction temperature range of -55 °C to +150 °C and provides an ESD capability exceeding 8 kV via the human body model. Packaged in a SOT-23 surface-mount housing, it is supplied in reels of 10,000 units.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Dual common anode configuration for space-efficient designs
• ESD protection rated above 8 kV (HBM) and 800 V (MM)
• RoHS-compliant construction

Applications

• Automotive electronic circuits requiring AEC-Q101 compliance
• Voltage reference applications utilizing dual common anode topology
• Clamping and protection stages in signal conditioning paths

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific HE3_A suffix corresponds to the required AEC-Q101 qualification status. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines prior to soldering.

Selection Notes

Select this variant when automotive-grade reliability is mandatory. The HE3_A suffix indicates AEC-Q101 qualification, whereas the base E3 version is commercial grade. Verify that the 3.9 V nominal voltage aligns with circuit requirements and that the ±5% tolerance meets design margins.

Part Context

This component belongs to the AZ23 series of small signal Zener diodes. The series offers various voltage grades according to the E24 standard. The AZ23C3V9-HE3_A-18 specifically denotes the 3.9 V voltage grade, common anode configuration, automotive qualification, and 10,000-unit reel packaging format.

Replacement Considerations

AZ23C3V9-E3-18: Commercial grade equivalent without AEC-Q101 qualification.
