BZB84-C75,215

Overview

The BZB84-C75,215 is a dual Zener diode in the BZB84 series, housed in a SOT-23 (TO-236AB) plastic surface-mounted package. It features a dual common anode configuration with two independent cathodes and one shared anode pin. The nominal Zener voltage is 75 V with a ±5% tolerance. Total power dissipation is rated at 300 mW per device. Key electrical parameters include a maximum reverse current of 255 μA at 52.5 V, a differential resistance of 255 Ω, and a temperature coefficient of 52.5 mV/K. The junction temperature range extends from -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for compact circuit design
• AEC-Q101 qualified for automotive reliability standards
• Small SOT-23 plastic package suitable for surface mounting

Applications

• General regulation functions

Procurement Notes

Verify the specific suffix '215' against official Nexperia documentation to confirm packaging details such as tape and reel specifications or manufacturing origin codes. Ensure the component matches the required AEC-Q101 qualification status if used in automotive contexts. Cross-reference the marking code 'PS' on the device body to confirm authenticity and correct voltage rating before integration into production lines.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a small footprint. The C-series designation indicates a wider ±5% voltage tolerance compared to the B-series. Consider the positive temperature coefficient at 75 V for thermal stability requirements. Verify that the total power dissipation limit of 300 mW accommodates the combined load of both diodes in the target application environment.

Part Context

This part belongs to the Nexperia BZB84 series of general-purpose dual Zener diodes. The series offers various voltage options ranging from 2.4 V to 75 V in the E24 range. The BZB84-Cxx variants specifically provide ±5% tolerance. These devices are designed for high-density circuit designs where space constraints necessitate the use of the SOT-23 package.

Replacement Considerations

Direct substitutes within the same family include other BZB84-Cxx parts with different voltage ratings but identical package and configuration. For single-diode applications, BZX84-C75 may be considered if only one channel is needed.
