Overview
The AZ23C22-E3-18 is a dual common anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 22 V with a tolerance of ±5%, tested at a current of 5 mA. The device has a maximum dynamic resistance of 55 Ohms and a reverse leakage current of 0.05 µA at 17 V. It operates within a temperature range of -55 °C to +150 °C, dissipating up to 300 mW on an FR-4 board. Packaged in an SOT-23 (TO-236-3) housing, it is supplied in reels of 10,000 units.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- Zener voltages graded according to the international E24 standard
- ESD capability exceeding 8 kV via human body model and 800 V via machine model
Applications
- Voltage reference applications requiring stable regulation
- Protection circuits utilizing dual common anode topology
- General purpose small signal clamping and switching
Procurement Notes
Verify the specific ordering suffix '-18' to confirm the 10,000-unit reel packaging format. Ensure the 'E3' designation aligns with RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number against official Vishay documentation to validate authenticity before procurement.
Selection Notes
Select this component when a dual common anode Zener array is required in an SOT-23 package. The ±5% tolerance suits general-purpose applications where tighter precision is unnecessary. Verify that the 300 mW power dissipation rating on an FR-4 board meets the thermal constraints of the target design environment.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes from Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V. Variants include different tolerances ('B' for ±2%, 'C' for ±5%) and packaging options ('-08' for 3,000 units, '-18' for 10,000 units).
Replacement Considerations
AZ23C22-E3-08: Identical electrical specifications but packaged in 3,000-unit reels instead of 10,000.
