BZB84-C68,215

Overview

The Nexperia BZB84-C68,215 is a dual Zener diode in a SOT-23 (TO-236AB) surface-mount package. It features a dual common anode configuration with two independent cathodes. The nominal Zener voltage is 68 V with a ±5% tolerance range of 64.0 V to 72.0 V at IZ = 2 mA. Total power dissipation is 300 mW per device. Key electrical parameters include a maximum reverse current of 240 μA and a differential resistance of 475 Ω. Operating temperature ranges from -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for compact circuit design
• Qualified for automotive applications under AEC-Q101 standards
• Small plastic SMD package suitable for high-density mounting

Applications

• General regulation functions

Procurement Notes

Verify the specific suffix '215' against official Nexperia documentation to confirm packaging details such as reel size or tape specifications. Ensure the component status matches current production requirements. Cross-reference the marking code 'PR' on the physical device to validate authenticity and correct type identification before integration into manufacturing processes.

Selection Notes

Select this part when a dual Zener solution sharing a common ground reference is required within a limited footprint. The C-series offers a wider voltage tolerance compared to the B-series. Verify that the 68 V breakdown voltage aligns with the target regulation level and that the 300 mW total power dissipation accommodates the expected thermal load in the final assembly environment.

Part Context

This component belongs to the BZB84 series of dual Zener diodes manufactured by Nexperia. The series provides various nominal voltages ranging from 2.4 V to 75 V in the E24 range. The BZB84-C68 variant specifically addresses applications requiring a 68 V reference point with standard tolerance characteristics in a widely used SOT-23 form factor.

Replacement Considerations

Direct substitutes within the same family include other BZB84-C variants with different voltage ratings. For single-diode equivalents, consider the BZX84 series. Verify pinout compatibility and thermal performance when substituting with components from other manufacturers offering similar SOT-23 dual Zener configurations.
