AZ23C3V9-HE3_A-08

Overview

The AZ23C3V9-HE3_A-08 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 housing, it is supplied in taped reels of 3000 units.

Feature Summary

• AEC-Q101 qualified for automotive applications
• Dual common anode configuration
• ESD protection exceeding 8 kV (HBM) and 800 V (MM)
• RoHS-compliant construction

Applications

• Automotive electronic circuits requiring AEC-Q101 compliance
• Voltage reference and regulation tasks
• Transient voltage suppression in signal lines

Procurement Notes

Verify the specific HE3_A suffix confirms AEC-Q101 qualification status before procurement. Confirm the tape and reel packaging matches the required manufacturing equipment specifications. Ensure the component meets RoHS compliance requirements for the target assembly process.

Selection Notes

Select this part when a dual Zener array with common anode topology is required. The ±5% tolerance suits general-purpose regulation. Verify that the 300 mW power dissipation on an FR-4 board aligns with the thermal design constraints of the application environment.

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 HE3_A variant specifically denotes the AEC-Q101 qualified version of the standard commercial grade devices.
