BZB84-C51-QR

Overview

The Nexperia BZB84-C51-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT23 (TO-236AB) surface-mount package. It features a dual common anode configuration with two independent cathodes. The device provides a nominal Zener voltage of 51 V with a tolerance of approximately ±5%. Key electrical parameters include a total power dissipation of 300 mW, a non-repetitive peak reverse power dissipation of 40 W, and a maximum forward voltage of 0.9 V at 10 mA. Operating characteristics specify a junction temperature range from -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for compact circuit design
• Qualified according to AEC-Q101 for automotive applications
• Small SOT23 plastic package suitable for surface-mounted design

Applications

• General regulation functions
• Automotive electronic circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets all required environmental and reliability standards for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener configuration is required within a small footprint. The C-series designation indicates an approximate ±5% voltage tolerance, which differs from the tighter B-series options. Ensure the application current remains within the specified limits to maintain stable regulation performance.

Part Context

This part belongs to the Nexperia BZB84-Q series, which comprises 74 types with nominal working voltages ranging from 2.4 V to 75 V. The series offers both ±2% (B-series) and approximately ±5% (C-series) tolerance options, providing flexibility for various precision requirements in low-power voltage regulation designs.

Replacement Considerations

Direct substitutes within the same family include BZB84-B51-QR for tighter tolerance or other BZB84-Q variants with different voltage ratings. Cross-manufacturer replacements require verification of pinout compatibility, package dimensions, and thermal characteristics.
