BZB84-B33,215

Overview

The Nexperia BZB84-B33,215 is a dual Zener diode in a SOT-23 (TO-236AB) surface-mount package. It features a dual common anode configuration with two independent cathodes and one shared anode. The nominal Zener voltage is 33 V with a ±2% tolerance. Key electrical parameters include a total power dissipation of 300 mW, a maximum reverse current of 80 μA at IZ=2 mA, and a differential resistance of 325 Ω. The device operates within a junction temperature range of -55 °C to +150 °C and supports non-repetitive peak reverse power dissipation up to 40 W.

Feature Summary

• Dual common anode configuration for compact circuit design
• Automotive AEC-Q101 qualification for reliability
• Wide working voltage range from 2.4 V to 75 V
• Small plastic SMD package suitable for automated assembly

Applications

• General regulation functions
• Voltage reference circuits
• Over-voltage protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm manufacturing origin and compliance status. Ensure the component matches the required tolerance series and package variant for the intended application. Cross-reference the part number with official Nexperia databases to confirm current production status and availability before finalizing procurement plans.

Selection Notes

Select this component when a dual Zener configuration with a common anode is required in a small SOT-23 footprint. The ±2% tolerance series is suitable for applications demanding tighter voltage accuracy compared to standard ±5% variants. Consider the thermal resistance and power dissipation limits when designing for high ambient temperatures or dense PCB layouts.

Part Context

This component belongs to the Nexperia BZB84 series of general-purpose dual Zener diodes. The series offers various voltage options and tolerance grades (B for ±2%, C for ±5%) within the same SOT-23 package. It is designed for low-power voltage regulation tasks where space efficiency and automotive-grade reliability are prioritized over high-current handling capabilities.

Replacement Considerations

Direct replacements must match the SOT-23 package, dual common anode configuration, and 33 V nominal voltage. Verify that alternative parts meet the same ±2% tolerance and thermal characteristics. Check for equivalent AEC-Q101 qualification if automotive usage is required.
