BZB84-C22,215

Overview

The Nexperia BZB84-C22,215 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 nominal Zener voltage is 22 V with a ±5% tolerance. Total power dissipation is 300 mW per device. Key electrical parameters include a maximum reverse current of 55 μA at IZ=5 mA, a differential resistance of 250 Ω, and a temperature coefficient ranging from 15.4 to 16.4 mV/K. Non-repetitive peak reverse current is 6.0 A for 100 μs pulses.

Feature Summary

• Dual common anode configuration allows compact circuit design
• AEC-Q101 qualified for automotive applications
• Small SOT-23 plastic package suitable for surface mounting

Applications

• General regulation functions

Procurement Notes

Verify the ordering suffix matches the required tape-and-reel packaging format. Confirm the specific marking code corresponds to the 22 V variant within the C-series tolerance group. Ensure the component status is active production rather than obsolete or preliminary data sheet versions before finalizing supply agreements.

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 standard 5% voltage tolerance suitable for general-purpose regulation. Verify that the 300 mW total power dissipation meets the thermal requirements of the target application environment.

Part Context

This component belongs to the Nexperia BZB84 series of dual Zener diodes. The series provides various nominal voltages from 2.4 V to 75 V in the same SOT-23 package. The 'C' designation indicates the ±5% tolerance grade, distinguishing it from the tighter ±2% 'B' grade variants within the same physical package family.

Replacement Considerations

Direct functional substitutes within the same package and configuration include other BZB84-C22 variants from different manufacturers if pinout compatibility is confirmed. Cross-reference with BZB84-B22 if tighter voltage tolerance is acceptable.
