BZB84-B68,215

Overview

The Nexperia BZB84-B68,215 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 68 V with a ±5% tolerance. Total power dissipation is 300 mW per device. Key electrical parameters include a maximum reverse current of 240 μA at IZ=0.5 mA, a differential resistance of 240 Ω at IZ=2 mA, and a temperature coefficient ranging from 47.6 to 79.8 mV/K. The junction temperature range is -55 °C to +150 °C.

Selection Notes

Select this component when a dual Zener solution is required in a small footprint. The BZB84-B68 variant provides a 68 V reference with tighter tolerance than the C-series. Ensure the circuit design accounts for the higher differential resistance and temperature coefficient associated with this voltage level compared to lower-voltage options.

Part Context

This part belongs to the BZB84 series of dual Zener diodes manufactured by Nexperia. The series offers various nominal voltages from 2.4 V to 75 V in both ±2% (B-series) and ±5% (C-series) tolerances. All variants share the same SOT-23 package and dual common anode pinout, allowing for flexible design choices within the same physical constraint.

Replacement Considerations

Direct replacements must match the dual common anode configuration and SOT-23 package. Other Nexperia BZB84-C68 variants or equivalent dual Zener diodes from other manufacturers with identical pinouts and electrical ratings may be substituted after verifying thermal and voltage specifications.
