BZB84-C75-QR

Overview

The Nexperia BZB84-C75-QR is a dual voltage regulator diode in an SOT23 (TO-236AB) surface-mounted package. It features a nominal Zener voltage of 75 V with a tolerance of approximately ±5 %. The device has a total power dissipation of 300 mW and supports junction temperatures up to 150 °C. Key electrical parameters include a maximum reverse current of 500 μA at 2 mA test current, a differential resistance of 52.5 Ω, and a capacitance of 0.05 pF. It is qualified according to AEC-Q101 for automotive applications.

Feature Summary

• Dual common anode configuration within a compact SOT23 plastic package
• Qualified for automotive applications per AEC-Q101 standards
• High non-repetitive peak reverse power dissipation capability

Applications

• General regulation functions

Procurement Notes

Verify the specific suffix -QR against the manufacturer's latest documentation to confirm reel packaging specifications. Ensure the component matches the required automotive qualification level. Cross-reference the marking code PS% with the official Nexperia table to validate authenticity upon receipt.

Selection Notes

Select this part when a dual Zener solution with a high voltage rating near 75 V is required in a small footprint. The C-series tolerance offers a balance between cost and precision. Verify that the thermal resistance characteristics fit the PCB layout constraints for the intended application environment.

Part Context

This component belongs to the BZB84-Q series, which provides dual Zener diodes in the SOT23 package. The series covers working voltages from 2.4 V to 75 V. The 'C' designation indicates the approximate ±5 % tolerance variant, distinguishing it from the tighter ±2 % B-series options within the same family.

Replacement Considerations

Check for other BZB84-C75-Q variants or single-diode equivalents if dual configuration is not strictly necessary. Verify pinout compatibility before substituting with similar dual Zener parts from other manufacturers.
