AZ23C36-E3-18

Overview

The AZ23C36-E3-18 is a dual common anode Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 36 V with a ±5% tolerance, tested at a current of 2 mA. The device has a maximum dynamic resistance of 87 Ω and a reverse leakage current of 50 μA at 27 V. Rated for surface mount installation in an SOT-23 package, it dissipates up to 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 providing two independent Zener elements in a single compact package
• Silicon planar construction designed for high reliability and stable electrical performance
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model

Applications

• Voltage reference circuits requiring dual regulated rails
• Overvoltage protection for sensitive input lines
• Clamping applications in signal conditioning stages

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm tape and reel specifications. Ensure that the commercial grade designation aligns with project requirements, as automotive qualified variants utilize different suffixes. Cross-reference the component marking code D68 to validate authenticity upon receipt.

Selection Notes

Select this variant when a dual Zener array with a 36 V breakdown voltage is required. The ±5% tolerance suits general-purpose regulation tasks where tighter precision is unnecessary. Consider the thermal resistance characteristics if operating near the upper limits of the specified ambient temperature range.

Part Context

This component belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers a wide range of standardized voltages from 2.2 V to 75 V. The 'E3' suffix indicates RoHS compliance and halogen-free construction, while the '-18' suffix specifies packaging in 10,000-unit reels on 13 mm tape.

Replacement Considerations

Direct substitutes include other AZ23C36 variants such as AZ23C36-G3-08 or AZ23C36-HE3_A-08, provided the packaging format matches the assembly line capabilities. Verify that alternative sources maintain the same SOT-23 footprint and pinout orientation.
