AZ23C5V6-E3-18

Overview

The AZ23C5V6-E3-18 is a silicon planar Zener diode from the Vishay AZ23 series, housed in an SOT-23 surface-mount package. It features a dual common-anode configuration with a nominal Zener voltage of 5.6 V and a tolerance of ±5%. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 500 mW when mounted on leads. Electrical characteristics include a maximum reverse leakage current of 1 µA at 3.8 V and a dynamic resistance of 40 Ω at a test current of 2 mA.

Feature Summary

• Dual common-anode Zener array configuration for space-efficient circuit designs
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
• RoHS-compliant commercial grade construction without automotive qualification

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Transient voltage suppression in signal conditioning paths
• Clamping applications in digital logic interfaces

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number and datasheet revision against authorized distribution channels. Confirm that the specific ordering suffix matches the required reel quantity and packaging format. Ensure compliance with RoHS directives and material categorization standards relevant to the target manufacturing region before finalizing acquisition.

Selection Notes

Select this component when a dual common-anode topology is required for voltage referencing or clamping. The ±5% tolerance suits general-purpose applications where tighter precision is unnecessary. Consider the thermal resistance and power dissipation limits relative to the expected ambient operating conditions and PCB footprint constraints.

Part Context

This device belongs to the AZ23 series of small-signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded Zener voltages according to the E24 standard. The specific suffix indicates a 10,000-unit tape-and-reel packaging format intended for automated surface-mount assembly processes.

Replacement Considerations

AZ23C5V6-E3-08 provides identical electrical specifications but utilizes an 8 mm tape on a 7-inch reel with a minimum order quantity of 15,000 units.
