AZ23C36-G3-18

Overview

The AZ23C36-G3-18 is a dual common anode Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It belongs to the AZ23-G series and utilizes a silicon planar structure housed in an SOT-23 (TO-236-3, SC-59) surface-mount package. The nominal Zener voltage is 36 V with a ±5% tolerance. Electrical characteristics include a test current of 2 mA, a maximum reverse leakage current of 0.05 µA at 27 V, and a dynamic resistance of 87 Ω at 2 mA. The device supports a maximum power dissipation of 300 mW on an FR-4 board and operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Silicon planar construction ensuring stable voltage regulation
• Green commercial grade material compliance

Applications

• Voltage reference circuits requiring dual regulated rails
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm reel size and tape specifications. Confirm RoHS3 compliance status and ensure the component meets the required AEC-Q101 qualification if automotive standards are necessary for the application.

Selection Notes

Select this part when a dual common anode topology is required for 36 V regulation. Ensure the operating current remains near the 2 mA test point to maintain accuracy. Verify that the thermal resistance allows for adequate heat dissipation within the 300 mW limit on the target PCB footprint.

Part Context

This component is part of the AZ23-G series, which offers a wide range of Zener voltages from 2.2 V to 75 V. The 'C' designation indicates a standard ±5% tolerance, while the 'G3' suffix denotes green commercial grade packaging. The '-18' suffix specifies the 10,000-unit reel format.

Replacement Considerations

AZ23B36-G3-18 provides a tighter ±2% tolerance variant within the same series.
