DZ23C9V1HE3-TP

Overview

The DZ23C9V1HE3-TP is a dual Zener diode in a common cathode configuration, housed in an SOT-23 package. It features a nominal Zener voltage of 9.1 V with a test current (IZT) of 5.0 mA and a maximum impedance (ZZT) of 10 Ω at this current. The device supports a power dissipation of 300 mW and operates within a junction temperature range of -55°C to +150°C. Key electrical parameters include a reverse leakage current (IR) of 0.1 µA at 7.0 V and a zener impedance (ZZK) of 100 Ω at a test current of 1.00 mA. The component is AEC-Q101 qualified and RoHS compliant.

Procurement Notes

Verify authenticity by purchasing only from Micro Commercial Components directly or their authorized distributors. Counterfeit parts are a known industry risk; unauthorized sources do not provide warranty coverage or traceability. Confirm the ordering suffix matches the required packaging format before finalizing orders.

Selection Notes

Select this component when a dual Zener solution is needed in an SOT-23 footprint. Ensure the 9.1 V nominal voltage aligns with circuit requirements. Consider the 300 mW power dissipation limit and thermal resistance of 417°C/W for heat management. Verify that the 5% voltage matching tolerance meets the precision needs of the application.

Part Context

This part belongs to the DZ23C series, which covers Zener voltages from 2.4 V to 47 V. All variants share the same SOT-23 package and general electrical characteristics, differing primarily in their specific Zener voltage ratings and associated marking codes. The series is designed for automated insertion and general-purpose voltage regulation.

Replacement Considerations

Direct substitutes must match the SOT-23 package, dual common cathode structure, and 9.1 V nominal voltage. Verify that alternative components meet the same AEC-Q101 qualification and 300 mW power rating. Check for equivalent impedance and leakage current specifications to ensure circuit compatibility.
