2BZX84C10

Overview

The Diotec Semiconductor 2BZX84C10 is a surface-mount planar Zener diode housed in an SOT-23 (TO-236) package. It features a common anode configuration with two integrated Zener diodes sharing a single cathode terminal. The device provides a nominal Zener voltage of 10 V, with a specified range of 9.4 V to 10.6 V at a test current of 5 mA. It supports a maximum power dissipation of 300 mW and operates within a junction temperature range of -50°C to +150°C. The component exhibits a dynamic resistance of less than 20 Ω and a reverse leakage current of 0.2 µA at 7 V.

Feature Summary

• Common anode dual-diode architecture for efficient circuit layout
• Sharp Zener voltage breakdown characteristics
• Low leakage current performance
• Compliant with RoHS directives without exemptions

Applications

• Voltage stabilization circuits
• Linear voltage regulators
• Reference voltage generation

Procurement Notes

Verify the specific ordering suffix against official Diotec documentation to confirm the exact grade and qualification level. Standard commercial grades differ from industrial or AEC-Q101 qualified variants. Ensure that the selected part number matches the required reliability standards for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener configuration with a shared common anode is required. The 10 V nominal rating suits applications needing precise reference levels. Verify thermal management requirements, as the 300 mW dissipation limit depends on PCB copper pad area. Confirm that the ±5% tolerance aligns with the system's voltage regulation accuracy specifications.

Part Context

This component belongs to the BZX84Cxx and 2BZX84Cxx series of SMD Planar Zener Diodes manufactured by Diotec Semiconductor. The series covers a wide voltage range from 2.4 V to 47 V. The '2' prefix specifically denotes the common anode variant, distinguishing it from the standard single-diode BZX84Cxx counterparts while maintaining identical electrical parameters and physical packaging.

Replacement Considerations

Direct functional substitutes include other common anode Zener diodes with matching 10 V ratings and SOT-23 packages. Verify pinout compatibility and dynamic resistance limits. Cross-reference with equivalent parts from other manufacturers ensuring identical power dissipation and temperature coefficients.
