Overview
The BAV70SRA-QZ is a small signal switching diode array manufactured by Nexperia. It features a quad common cathode configuration housed in an SOT-363 surface-mount package. Key electrical parameters include a maximum repetitive peak reverse voltage of 100 V and a continuous forward current of 355 mA per diode. The device exhibits a low forward voltage drop of 1.25 V at specified currents and a fast reverse recovery time of 4 ns. It supports a surge current of 4 A and has a power dissipation rating of 250 mW.
Feature Summary
- Quad common cathode architecture for efficient space-saving circuit design
- Fast switching capability with 4 ns reverse recovery time
- High surge current handling capacity for robust transient protection
Applications
- General-purpose signal switching in consumer electronics
- Protection circuits in automotive infotainment systems
- Logic level shifting and clamping applications
Procurement Notes
Verify the specific suffix 'QZ' to confirm the tape-and-reel packaging format and automotive qualification status. Ensure the ordering code matches the required SOT-363 package variant. Cross-reference the datasheet revision date to confirm compliance with current RoHS and REACH directives before finalizing procurement orders.
Selection Notes
Select this component when a compact quad diode solution is required for high-speed switching applications. The common cathode configuration simplifies PCB layout compared to discrete components. Consider the 100 V reverse voltage rating for suitability in low-voltage digital logic interfaces and signal processing paths where minimal capacitance and fast response are critical.
Part Context
This part belongs to Nexperia's BAV series of small signal switching diodes, designed for general-purpose applications. The 'Q' designation indicates automotive grade qualification, while 'SRA' specifies the SOT-363 surface-mount package. This series is widely used in portable devices and automotive electronics due to its small footprint and reliable performance characteristics.
Replacement Considerations
Check for direct pin-compatible alternatives such as the BAV70WT or BAV99 variants if different packaging or slightly altered electrical characteristics are acceptable. Verify that any substitute maintains the quad common cathode topology and meets the 100 V reverse voltage requirement for equivalent circuit functionality.
