AZ23C22W-TP

Overview

The AZ23C22W-TP is a Zener diode array manufactured by Micro Commercial Components (MCC). It features a dual common anode configuration housed in an SOT-323 surface-mount package. The nominal Zener voltage is 22 V with a tolerance of ±5%. Maximum power dissipation is rated at 200 mW, and the maximum Zener impedance is 55 Ohms. Reverse leakage current is specified as 100 nA at 17 V. The device operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Surface-mount SOT-323 packaging suitable for automated assembly
• High-temperature operation capability up to 150°C junction temperature

Applications

• Voltage reference circuits requiring dual rail protection
• Clamping applications in signal conditioning paths
• Over-voltage protection for low-power electronic modules

Procurement Notes

Verify component authenticity through authorized MCC distributors or certified suppliers. Request original datasheets and material compliance certificates upon order confirmation. Inspect incoming shipments for package integrity and marking legibility. Confirm lot traceability documentation matches purchase orders. Validate electrical parameters against specification limits during incoming quality control testing.

Selection Notes

Select this component when a dual Zener solution fits within an SOT-323 footprint constraint. Ensure the 200 mW power rating meets thermal requirements of the target application. Verify that the 22 V breakdown voltage aligns with system voltage thresholds. Consider the 55 Ohm impedance value for dynamic load performance needs.

Part Context

This part belongs to the AZ23C series of Zener arrays from Micro Commercial Components. It shares functional similarities with other variants like AZ23C22-TP but differs in package type and power rating. The W suffix typically denotes specific packaging or tape-and-reel configurations within the product line.

Replacement Considerations

AZ23C22-G3-18 is a pin-compatible alternative from Vishay General Semiconductor offering identical 22 V functionality in an SOT-23-3 package with 300 mW power rating.
