AZ23C13-TP

Overview

The AZ23C13-TP is a dual Zener diode manufactured by Micro Commercial Components (MCC). It features a common anode configuration housed in an SOT-23 surface-mount package. The device provides a nominal Zener voltage range of 12.4 V to 14.1 V at a test current of 5 mA. It has a maximum power dissipation of 300 mW and a Zener impedance of 110 Ohms. The reverse leakage current is specified at 0.1 µA with a reverse voltage of 10 V. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 package for space-constrained designs.
• Common anode configuration simplifies circuit layout and reduces component count.
• High thermal stability with an operating junction temperature range extending to +150°C.

Applications

• Voltage reference circuits requiring stable dual voltage levels.
• Transient voltage suppression in low-power signal lines.
• Clamping applications in portable electronic devices.

Procurement Notes

Verify the specific suffix and packaging format when ordering, as MCC offers variations such as HE3 or W-TP which may differ in environmental compliance or physical dimensions. Confirm that the standard factory pack quantity aligns with production requirements. Ensure the selected variant matches the required Zener voltage tolerance and package type for the target PCB footprint.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a small form factor. The 300 mW power rating suits low-current applications. Compare the 110 Ohm impedance against load requirements to ensure adequate regulation. Verify that the 12.4 V to 14.1 V voltage range fits the design specifications before finalizing the part number.

Part Context

This part belongs to the AZ23C series of dual Zener diodes from Micro Commercial Components. The series typically includes variants with different voltage ratings and configurations, all sharing the SOT-23 package style. The AZ23C13-TP specifically targets applications needing two regulated voltages from a single common point, offering a compact alternative to discrete components.

Replacement Considerations

Direct replacements must match the SOT-23-3 package, common anode configuration, and similar Zener voltage range (12.4–14.1 V). Check manufacturer datasheets for equivalent parts from other suppliers to ensure pin compatibility and electrical parameter alignment.
