BZB84-C2V7-QR

Overview

The Nexperia BZB84-C2V7-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT-23 (TO-236AB) surface-mount package. It features a dual common anode configuration with two independent cathodes. The device provides a nominal Zener voltage of 2.7 V with a tolerance of approximately ±5 %. Total power dissipation is rated at 300 mW, while non-repetitive peak reverse power dissipation reaches 40 W. Operating junction temperature ranges from -55 °C to +150 °C. Reverse current is specified at 20 μA maximum at IZ = 5 mA, and differential resistance is 100 Ω.

Feature Summary

• Dual common anode configuration allows for compact circuit designs requiring two regulated voltages or polarity protection.
• Qualified according to AEC-Q101 standards, making it suitable for automotive electronic applications.
• Small plastic SOT-23 package facilitates high-density surface-mounted design.

Applications

• General regulation functions
• Automotive electronics circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct tolerance and packaging specifications. Confirm that the component meets the required AEC-Q101 qualification status for your intended application environment. Cross-reference the marking code UA% on the physical device to validate authenticity and part identity before integration into production lines.

Selection Notes

Select this component when a dual common anode topology is required within a small SOT-23 footprint. The C-series tolerance of approximately ±5 % suits general regulation tasks where tight voltage precision is not critical. Ensure the total power dissipation of 300 mW aligns with the thermal management capabilities of the target PCB layout and operating ambient conditions.

Part Context

This device belongs to the Nexperia BZB84-Q series, which offers a comprehensive range of dual Zener diodes for automotive and industrial use. The series includes various voltage options from 2.4 V to 75 V in both B (±2 %) and C (±5 %) tolerance grades. All variants share the same SOT-23 package and pinout, simplifying inventory management for designs utilizing multiple voltage references.

Replacement Considerations

Direct substitutes within the same family include BZB84-B2V7-Q (tighter ±2 % tolerance) or other BZB84-Q series parts with identical pinouts. Non-series replacements must match the SOT-23 package, 300 mW power rating, and dual common anode configuration while verifying electrical parameters like Zener voltage and leakage current.
