BZB84-B3V6-QR

Overview

The Nexperia BZB84-B3V6-QR is a dual voltage regulator diode in the BZB84-Q series, housed in a SOT-23 surface-mount package. It features a dual common anode configuration with two independent cathodes (K1, K2) and one shared anode (CA). The device provides a nominal Zener voltage of 3.6 V with a ±2% tolerance (Series B). Key electrical parameters include a total power dissipation of 300 mW, a non-repetitive peak reverse power dissipation of 40 W per diode, and a maximum forward voltage of 0.9 V at 10 mA. Operating temperatures range from -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for compact circuit design
• Qualified according to AEC-Q101 for automotive applications
• High non-repetitive peak reverse power dissipation capability

Applications

• General regulation functions

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as reel size or tape-and-reel specifications. Confirm that the component meets all required automotive qualification standards if intended for vehicle electronics. Ensure compatibility with standard SOT-23 footprint dimensions during PCB layout.

Selection Notes

Select this component when a dual Zener diode with a common anode is required in a small SMD package. The B-series designation indicates a tighter ±2% voltage tolerance compared to the C-series. Consider the 300 mW total power dissipation limit and the thermal resistance characteristics when designing for high-density circuits or elevated ambient temperatures.

Part Context

This part belongs to the Nexperia BZB84-Q series, which comprises 74 types of dual voltage regulator diodes. The series offers nominal working voltages ranging from 2.4 V to 75 V in both E24 preferred value ranges. All variants share the same SOT-23 plastic package and are designed for surface-mounted assembly in general-purpose electronic applications.

Replacement Considerations

Direct functional substitutes within the same family include other BZB84-Q series parts with identical pinouts but different voltage ratings, such as BZB84-B3V3-QR or BZB84-B3V9-QR. Cross-family replacements require verification of pin compatibility and power dissipation limits.
