AZ23C3V3-G3-18

Overview

The AZ23C3V3-G3-18 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common anode configuration within a SOT-23 surface-mount package. The nominal Zener voltage is 3.3 V with a tolerance of ±5%. Electrical characteristics include a maximum reverse leakage current of 5 μA at 1 V and a dynamic resistance of 95 Ω at a test current of 5 mA. The device supports a power dissipation of up to 300 mW on an FR-4 board, operates across a temperature range of -55°C to +150°C, and complies with RoHS3 standards.

Feature Summary

• Dual common anode configuration for integrated circuit protection
• Silicon planar construction ensuring high reliability
• ESD capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Input protection against electrostatic discharge in portable electronics
• Clamping applications in signal conditioning interfaces

Procurement Notes

Verify the specific ordering suffix '-18' to confirm the 10,000-unit reel packaging format. Ensure compliance requirements match the 'G3' designation for lead-free and halogen-free specifications. Confirm that the AEC-Q101 qualification status meets project needs, as it may require separate verification from the manufacturer.

Selection Notes

Select this component when a dual common anode topology is required for shared ground references. The 3.3 V nominal voltage suits logic-level protection tasks. Verify that the 95 Ω dynamic resistance aligns with transient suppression requirements. Consider thermal derating if ambient temperatures exceed standard operating ranges.

Part Context

This part belongs to the AZ23-G series of small signal Zener diodes. The series offers various voltage grades according to the E24 standard. The 'C' suffix indicates a ±5% voltage tolerance, while the 'B' suffix denotes ±2% tolerance. All variants share the same SOT-23 footprint and electrical testing conditions.
