BZX84-C56-QR

Single Zener Diodes Overview

The Nexperia BZX84-C56-QR is a low-power voltage regulator diode housed in an SOT-23 (TO-236AB) surface-mounted plastic package. It provides a nominal Zener voltage of 56 V with a tolerance of approximately ±5 %. The device operates within a temperature range of -55 °C to +150 °C and dissipates up to 250 mW at 25 °C ambient. Key electrical characteristics include a maximum reverse current of 200 μA, a non-repetitive peak reverse power dissipation of 40 W, and a forward voltage of 0.9 V at 10 mA.

Single Zener Diodes Feature Summary

• Qualified according to AEC-Q101 for automotive applications
• Low-power operation with total power dissipation up to 250 mW
• Compact SOT-23 surface-mount package design

Single Zener Diodes Applications

• General regulation functions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'QR' against official Nexperia documentation to confirm reel packaging specifications. Ensure the component meets AEC-Q101 requirements if intended for automotive use. Cross-reference the marking code '%B8' with datasheet tables to validate authenticity during inspection.

Single Zener Diodes Selection Notes

Select this component when a nominal 56 V regulation point is required with standard ±5 % tolerance. The SOT-23 package suits space-constrained designs. Verify that the operating current aligns with the specified test conditions for optimal performance and thermal management.

Single Zener Diodes Part Context

This part belongs to the BZX84-Q series, which includes 37 breakdown voltages ranging from 2.4 V to 75 V. The series offers three tolerance options: ±1 %, ±2 %, and approximately ±5 %. The C-series designation specifically indicates the approximate ±5 % tolerance variant within this standardized lineup.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same family include BZX84-B56-QR (±2 % tolerance) and BZX84-A56-QR (±1 % tolerance). These variants share identical pinouts and packages but offer tighter voltage accuracy.
