BZB84-B3V3,215

Overview

The Nexperia BZB84-B3V3,215 is a dual Zener diode in a SOT-23 (TO-236AB) surface-mount package. It features a common anode configuration with two independent cathodes. The nominal Zener voltage is 3.3 V with a ±2% tolerance series designation. Total power dissipation is 300 mW per device. Key electrical parameters include a maximum reverse current of 5 μA at IZ=5 mA and a differential resistance of 95 Ω. The non-repetitive peak reverse power dissipation reaches 40 W for short pulses. Operating junction temperature ranges from -55 °C to +150 °C.

Feature Summary

• Dual Zener diodes integrated in a single small plastic SMD package
• Common anode configuration suitable for compact circuit designs
• Qualified for automotive applications under AEC-Q101 standards

Applications

• General regulation functions

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm tape-and-reel packaging details and manufacturing origin. Ensure the component status remains active for production use by consulting official Nexperia channels before finalizing supply chain agreements.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a SOT-23 footprint. The ±2% tolerance variant provides tighter voltage accuracy compared to the standard ±5% series. Confirm that the 300 mW total power dissipation rating meets the thermal requirements of the target application environment.

Part Context

This part belongs to the BZB84 series of dual Zener diodes manufactured by Nexperia. The series offers a wide working voltage range from 2.4 V to 75 V in the E24 range. It is designed for general-purpose voltage regulation in high-density surface-mounted electronic circuits.

Replacement Considerations

Direct substitutes within the same series include BZB84-C3V3 for ±5% tolerance or other BZB84 variants with different voltage ratings. Cross-package replacements require verifying pin compatibility and thermal characteristics.
