BZX84-C56,215

Single Zener Diodes Overview

The Nexperia BZX84-C56,215 is a voltage regulator diode in the BZX84 series, housed in an SOT-23 (TO-236AB) surface-mount package. It features a nominal working voltage of 56 V with approximately ±5% tolerance. The device has a total power dissipation of 250 mW and a non-repetitive peak reverse power dissipation of 40 W. Key electrical characteristics include a maximum differential resistance of 425 Ω at IZ = 2 mA, a maximum reverse current of 200 μA at VR = 63.8 V, and a typical temperature coefficient of 0.05 mV/K.

Single Zener Diodes Feature Summary

• Low-power voltage regulation in a compact SOT-23 plastic package
• Approximately ±5% tolerance for normalized E24 breakdown voltages
• High non-repetitive peak reverse power dissipation capability

Single Zener Diodes Applications

• General regulation functions

Single Zener Diodes Procurement Notes

Verify that the specific part number BZX84-C56,215 matches the required 56 V nominal voltage and ±5% tolerance specifications. Confirm the SOT-23 package type aligns with PCB layout constraints. Ensure the application environment does not exceed the 250 mW total power dissipation limit or the 150 °C junction temperature rating defined in the absolute maximum ratings.

Single Zener Diodes Selection Notes

Select this component when a standard 56 V reference is needed in space-constrained designs requiring surface-mount assembly. The BZX84-C suffix indicates the approximate ±5% tolerance band suitable for general-purpose applications where tighter precision is not critical. Consider the thermal resistance characteristics if operating near the maximum power dissipation limits.

Single Zener Diodes Part Context

This component belongs to the Nexperia BZX84 series of low-power voltage regulator diodes. The series offers 37 breakdown voltages ranging from 2.4 V to 75 V across three tolerance variants: ±1% (BZX84-A), ±2% (BZX84-B), and approximately ±5% (BZX84-C). All variants share the same SOT-23 package and basic electrical structure.

Single Zener Diodes Replacement Considerations

Other BZX84-C56 variants from Nexperia may serve as substitutes if the tolerance and package match. Cross-brand replacements must be verified against the 56 V nominal voltage, 250 mW power dissipation, and SOT-23 footprint requirements.
