The BAV70DW-AQ is a small signal diode array manufactured by Diotec Semiconductor, featuring two high-speed switching diodes with common cathodes. It is housed in an SOT-363 surface-mount package and complies with AEC-Q101 automotive standards. The device supports a repetitive peak reverse voltage of 100 V and a maximum average forward current of 150 mA per diode. Key electrical characteristics include a reverse recovery time of less than 4 ns, a junction capacitance of approximately 2 pF, and a power dissipation rating of 200 mW.
Verify the specific suffix -AQ to confirm AEC-Q101 qualification status against official manufacturer documentation. Ensure that the SOT-363 package dimensions and pinout configuration match the target PCB layout requirements. Confirm compliance with RoHS, REACH, and conflict mineral regulations as stated in the product datasheet before finalizing procurement specifications.
Select this component when automotive-grade reliability and high-speed performance are required in a compact surface-mount form factor. The dual common-cathode configuration allows for efficient space utilization in dense circuit designs. Consider the 150 mA average forward current limit and 100 V reverse voltage rating to ensure adequate headroom for the intended operating conditions.
This part belongs to the BAS16DW, BAV70DW, BAV756DW, and MMBD4448SDW family of SMD small signal diode arrays from Diotec Semiconductor. These devices share similar packaging and manufacturing technologies but differ in internal configurations and specific electrical ratings. The BAV70DW variant specifically provides a dual common-cathode arrangement optimized for general-purpose high-speed switching tasks.
