AZ23C2V2-G3-18

Overview

The Vishay AZ23C2V2-G3-18 is a silicon planar Zener diode from the AZ23-G series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 2.2 V with a ±5% tolerance range spanning 2.09 V to 2.31 V at a test current of 5 mA. The device features a maximum reverse leakage current of 1 μA and dynamic resistance values of 120 Ω at IZT1 and 600 Ω at IZT2. Operating within a temperature range of -55 °C to +150 °C, it offers ESD protection exceeding 8 kV (HBM) and 800 V (MM).

Feature Summary

• Dual common-anode configuration for integrated circuit applications.
• High electrostatic discharge robustness compliant with AEC-Q101 standards.
• Green commercial grade construction without halogenated additives.

Applications

• Voltage reference circuits requiring low-voltage stability.
• ESD protection networks in portable electronics.

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and material categorization documentation prior to integration. Ensure storage conditions maintain moisture sensitivity level 1 integrity. Validate marking codes against official datasheet specifications to prevent counterfeit substitution during assembly.

Selection Notes

Select this variant when a dual common-anode topology is required alongside precise low-voltage regulation. The 5% tolerance suits general-purpose stabilization where tighter limits are unnecessary. Evaluate thermal dissipation requirements against the 300 mW limit on FR-4 substrates. Consider the negative temperature coefficient characteristics for ambient compensation strategies.
