BAV70QB-QZ

Overview

BAV70QB-QZ is a triple diode array from Nexperia, featuring three electrically isolated epitaxial diodes in a single SOT363 surface-mount package. The device is designed for medium-speed switching applications with a maximum repetitive peak reverse voltage of 100 V and a forward current rating of 350 mA per diode. It utilizes a wettable flank lead configuration to enhance solder joint inspection reliability. The component operates within a temperature range of -55 °C to +150 °C and includes an exposed pad for improved thermal dissipation.

Feature Summary

• Triple diode configuration with internal electrical isolation between individual diode elements
• Wettable flank lead design facilitates visual inspection of solder joints for quality assurance
• Medium-speed switching characteristics optimized for signal processing tasks
• Exposed thermal pad structure supports efficient heat transfer in compact layouts

Applications

• Signal rectification in mixed-signal circuits
• Logic level shifting and protection
• OR-ing configurations for power path management

Procurement Notes

Verify the specific suffix 'QZ' against the manufacturer's official documentation to confirm the presence of the wettable flank feature and exact tape-and-reel specifications. Ensure that the procurement channel provides traceability to Nexperia USA Inc. or authorized distributors to guarantee component authenticity and compliance with automotive-grade standards if required by the application.

Selection Notes

Select this component when space-constrained designs require multiple isolated diodes within a single footprint. The SOT363 package offers a compact solution compared to discrete components. Consider the 100 V reverse voltage rating and 350 mA current capacity to ensure adequate headroom for the intended circuit loads and transient conditions.

Part Context

The BAV70QB-QZ belongs to Nexperia's portfolio of bipolar diode arrays, specifically engineered for high-reliability environments. The 'Q' designation indicates qualification for automotive applications, adhering to strict quality and reliability standards. This series complements other small-signal diode offerings by providing integrated solutions that reduce board space and assembly complexity.

Replacement Considerations

Direct substitutes include BAV70WBZ and BAV70WT1G, which share similar electrical ratings but may differ in package type or lead configuration. Verify pinout compatibility and thermal performance before substitution.
