BZB84-C27,215

Overview

The Nexperia BZB84-C27,215 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 27 V with a ±5% tolerance. Total power dissipation is 300 mW at 25 °C ambient temperature. Forward voltage is 0.9 V at 10 mA test current. Differential resistance is 80 Ω at 2 mA. Reverse current is 300 μA at 2 mA and 80 μA at 0.5 mA. Temperature coefficient is 21.4 mV/K at 2 mA. Diode capacitance is 50 pF at 1 MHz. Non-repetitive peak reverse current is 1.0 A at VR = 50 V.

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select the BZB84-C series when a wider voltage tolerance of ±5% is acceptable compared to the ±2% B series. Ensure the operating current aligns with the specified test conditions for accurate voltage regulation. Verify that the total power dissipation requirements do not exceed 300 mW under maximum ambient temperature conditions.

Part Context

This component belongs to the BZB84 series of general-purpose dual Zener diodes manufactured by Nexperia. The series offers a wide range of nominal working voltages from 2.4 V to 75 V. All variants share the same SOT-23 package and common anode topology, differing primarily in Zener voltage specifications and tolerance grades.

Replacement Considerations

Direct substitutes within the same family include BZB84-B27,215, which shares the same package and electrical characteristics but offers a tighter ±2% voltage tolerance instead of ±5%.
