2BZX84C30

Overview

The Diotec Semiconductor 2BZX84C30 is a surface-mount planar Zener diode housed in an SOT-23 (TO-236) package. It features a common anode configuration with two integrated diodes, providing a nominal Zener voltage range of 28 V to 32 V at a test current of 5 mA. The device supports a maximum power dissipation of 300 mW and operates within a junction temperature range of -50°C to +150°C. Standard tolerance follows the E24 series at ±5%, with a dynamic resistance under 80 Ohms and a reverse leakage current of 1 µA at 1 V.

Feature Summary

• Common Anode Configuration: Integrates two Zener diodes sharing a single anode terminal for efficient circuit layout.
• Sharp Breakdown Characteristics: Delivers precise voltage regulation with low leakage current for stable performance.
• Automotive Compliance Options: Available in AEC-Q101 compliant and qualified grades for automotive electronics applications.

Applications

• Voltage stabilization and regulators
• Dual-channel reference circuits
• Signal clamping

Procurement Notes

Verify the specific suffix when ordering. The standard commercial grade lacks an additional suffix, while industrial grade uses no suffix. Automotive-grade parts require the -Q or -AQ suffixes. Confirm RoHS compliance status and REACH registration requirements prior to procurement to ensure alignment with project specifications.

Selection Notes

Select this component for designs requiring dual Zener functions in a compact footprint. Ensure the total power dissipation does not exceed 300 mW on a PCB with 3 mm² copper pads per terminal. Verify that the required Zener voltage falls within the 28 V to 32 V range and that the operating temperature remains within the specified limits.

Part Context

This part belongs to the BZX84Cxx and 2BZX84Cxx series from Diotec Semiconductor. The '2' prefix indicates a common anode structure, distinguishing it from the single-diode BZX84C variants. The series covers a wide voltage range from 2.4 V to 47 V, offering flexibility for various voltage regulation needs in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other common anode Zener diodes in SOT-23 packages with matching voltage ratings. Verify pinout compatibility and thermal resistance characteristics. Alternative single-diode equivalents may require circuit redesign to accommodate the shared anode topology.
