AZ23C11-E3-08

Overview

The AZ23C11-E3-08 is a dual common anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 11 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and dissipates up to 300 mW on an FR-4 board. It utilizes the SOT-23 surface-mount package, complies with RoHS standards, and supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• Silicon planar technology ensuring stable voltage regulation
• RoHS-compliant commercial grade construction

Applications

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

Procurement Notes

Verify that the ordering code matches the specific suffix requirements for reel size and tape width. Confirm compliance with environmental directives such as RoHS3 before finalizing procurement orders. Ensure storage conditions align with moisture sensitivity level 1 specifications to prevent package damage during assembly.

Selection Notes

Select this component when a dual Zener array with a 11 V nominal rating and ±5 % tolerance is required. Verify that the maximum power dissipation of 300 mW meets the thermal constraints of the target application. Ensure the SOT-23 footprint dimensions are compatible with the printed circuit board layout.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes produced by Vishay Semiconductors. The series offers various voltage grades according to the E24 standard. The 'C' designation indicates the ±5 % voltage tolerance, while the 'E3' suffix denotes RoHS compliance for commercial grade products.

Replacement Considerations

AZ23C11-E3-18 provides identical electrical characteristics but is supplied in 10,000-unit reels instead of 3,000-unit reels.
