BZB84-C20,215

Overview

The Nexperia BZB84-C20,215 is a dual Zener diode in a SOT-23 (TO-236AB) plastic surface-mounted package. It features a dual common anode configuration with two independent cathodes and one shared anode pin. The device provides a nominal working voltage of 20 V with a ±5% tolerance series designation. Total power dissipation is rated at 300 mW per device. Key electrical parameters include a maximum reverse current of 55 μA at IZ=5 mA, a differential resistance of 225 Ω, and a temperature coefficient of 14.4 mV/K. Non-repetitive peak reverse power dissipation reaches 40 W for short pulses.

Feature Summary

• Dual common anode configuration enabling compact circuit design
• Automotive qualification compliant with AEC-Q101 standards
• Small SOT-23 plastic package optimized for surface-mount assembly

Applications

• General regulation functions

Procurement Notes

Verify the specific ordering suffix to confirm manufacturing origin details. Confirm that the component status remains active for production use. Ensure compatibility with standard SOT-23 footprints during PCB layout. Check for any recent product change notices affecting specifications or reliability data before finalizing procurement plans.

Selection Notes

Select this part when a dual Zener solution with a common anode is required in a small footprint. The C-series offers a wider voltage tolerance compared to the B-series. Consider the thermal resistance characteristics and total power dissipation limits relative to the expected operating ambient temperature and load conditions.

Part Context

This component belongs to the Nexperia BZB84 series, which encompasses 74 types covering nominal voltages from 2.4 V to 75 V. The series includes both B (±2%) and C (±5%) tolerance variants. All devices share the same SOT-23 package and dual common anode topology, providing a standardized platform for various voltage reference and regulation needs.

Replacement Considerations

Direct substitutes within the same family include BZB84-B20,215 for tighter tolerance requirements. Other voltage levels in the BZB84-C series can replace this unit if different regulation points are acceptable.
