AZ23C4V3-E3-08

Overview

The AZ23C4V3-E3-08 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common anode configuration with two elements housed in a SOT-23 surface-mount package. The nominal Zener voltage is 4.3 V, with a tolerance of ±5%. Electrical characteristics include a maximum reverse leakage current of 3 μA at 3 V and a dynamic resistance of 90 Ω at a test current of 5 mA. The device supports a power dissipation of up to 500 mW and operates within a temperature range of -55 °C to +150 °C.

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 applications requiring stable low-voltage regulation
• Protection against electrostatic discharge (ESD) in sensitive electronics
• Clamping circuits in signal processing lines

Procurement Notes

Verify the specific ordering code suffix to confirm packaging quantity and reel diameter. The base part number AZ23C4V3-E3-08 indicates standard commercial grade RoHS compliance. Confirm that the required tape and reel specifications match the manufacturing lot details provided by the supplier before finalizing procurement orders.

Selection Notes

Select this component when a dual common anode Zener array is required for space-constrained designs. Ensure the 4.3 V nominal voltage aligns with the target clamping or reference requirements. Verify that the ±5% tolerance meets the circuit's precision needs and that the SOT-23 package dimensions fit the available PCB footprint.

Part Context

This component belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers a wide range of Zener voltages from 2.2 V to 75 V. The 'C' designation specifically denotes the ±5% voltage tolerance grading according to the international E24 standard, distinguishing it from the tighter ±2% tolerance 'B' variant.

Replacement Considerations

AZ23B4V3-E3-08 provides equivalent functionality with a tighter ±2% voltage tolerance.
