AZ23C2V7-HE3-18

Overview

The AZ23C2V7-HE3-18 is a dual common anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 2.7 V with a ±5% tolerance, tested at a current of 5 mA. The device has a maximum power dissipation of 300 mW on an FR-4 board and operates within a temperature range of -55 °C to +150 °C. Packaged in a surface-mount SOT-23-3 housing, it meets RoHS compliance standards and holds AEC-Q101 automotive qualification.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• AEC-Q101 qualified for automotive reliability requirements
• ESD protection capability exceeding 8 kV via human body model

Applications

• Automotive electronic systems requiring robust voltage regulation
• Low-voltage reference circuits in compact surface-mount layouts
• Protection stages utilizing high ESD tolerance thresholds

Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm package tape dimensions and reel quantity. Ensure that the HE3_A designation aligns with required automotive grade specifications rather than commercial variants. Cross-reference the manufacturer's latest datasheet revision to validate current production status and any potential material categorization updates prior to finalizing procurement orders.

Selection Notes

Select this component when a dual common anode topology is necessary for low-voltage clamping or reference applications. The 2.7 V nominal rating suits circuits requiring precise sub-3 V regulation. Confirm that the 300 mW thermal dissipation limit on standard PCB footprints accommodates the expected operating conditions without exceeding the maximum junction temperature threshold.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes from Vishay Semiconductors. The series offers graded voltages according to the international E24 standard. The 'C' suffix indicates a standard ±5% tolerance, while the 'HE3_A' suffix denotes AEC-Q101 qualification. The '-18' suffix specifies the standard 10,000-unit reel packaging format.
