2BZX84C9V1

Overview

The Diotec Semiconductor 2BZX84C9V1 is a surface-mount planar Zener diode housed in an SOT-23 package. It operates as a common anode device with a nominal Zener voltage range of 8.5 V to 9.6 V at a test current of 5 mA. The component supports a maximum power dissipation of 300 mW and functions within a junction temperature range of -50°C to +150°C. Standard tolerance follows the E24 series, providing ±5% accuracy. The device features low leakage current and sharp breakdown characteristics suitable for precision voltage regulation.

Feature Summary

• Sharp Zener voltage breakdown profile
• Low reverse leakage current
• RoHS compliant without exemptions

Applications

• Voltage stabilization circuits
• DC voltage regulators

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact grade and compliance level. Confirm that the commercial or industrial grade aligns with the project requirements. Ensure the SOT-23 footprint matches the PCB layout specifications before finalizing procurement.

Selection Notes

Select this component when a common anode configuration is required for dual-diode applications. Verify that the 300 mW power rating accommodates the thermal dissipation needs of the target circuit. Ensure the operating voltage falls within the specified 8.5 V to 9.6 V window under expected load conditions.

Part Context

This part belongs to the BZX84Cxx and 2BZX84Cxx family of SMD Planar Zener Diodes from Diotec Semiconductor. The '2' prefix indicates a common anode structure, distinguishing it from the single-diode BZX84C variants. The family covers a wide voltage range from 2.4 V to 47 V in the same compact SOT-23 form factor.

Replacement Considerations

Direct pin-compatible replacements include other manufacturers' SOT-23 common anode Zener diodes rated at 9.1 V with similar power dissipation. Verify dynamic resistance and leakage current specifications match the original design constraints.
