BZB84-C6V8-QR

Overview

The Nexperia BZB84-C6V8-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT23 (TO-236AB) surface-mounted plastic package. It features a dual common anode configuration with two independent cathodes sharing a single anode terminal. The device provides a nominal Zener working voltage of 6.8 V with approximately ±5 % tolerance. Total power dissipation is rated at ≤300 mW, and it supports non-repetitive peak reverse power dissipation up to 40 W. Qualified under AEC-Q101 for automotive applications, it operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details and tape-and-reel specifications. Ensure that the component matches the required AEC-Q101 qualification status if intended for automotive use. Cross-reference the marking code 'UM' on the physical device to validate authenticity and correct part identification before integration into production lines.

Selection Notes

Select this component when a dual Zener configuration with a shared anode is required in a small surface-mount footprint. The C-series designation indicates an approximate ±5 % voltage tolerance, which is suitable for general regulation tasks where tighter precision is not critical. Consider the thermal resistance characteristics and total power dissipation limits relative to the expected ambient operating conditions and PCB copper area available for heat sinking.

Part Context

This component belongs to the BZB84-Q series, which comprises 74 types of dual voltage regulator diodes. The series covers nominal working voltages ranging from 2.4 V to 75 V in the E24 range.
