Quad common cathode configuration for general-purpose switching applications
Fast switching speed with a maximum reverse recovery time of 4 ns
Low forward voltage drop of 0.72 V at 5 mA
Low reverse leakage current of 100 nA at 70 V

Applications

General-purpose switching circuits
High-speed signal processing
DC-DC converter output rectification

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact package type and packing quantity. Confirm RoHS compliance status and environmental specifications such as halogen-free requirements before finalizing procurement orders. Ensure the component matches the required automotive or industrial qualification standards if applicable to the design.

Selection Notes

Select this component when a compact quad common cathode arrangement is required for high-speed switching tasks. The SOT-353 package provides space efficiency while maintaining a 500 mA current rating. Consider the 4 ns reverse recovery time for applications demanding rapid signal transitions and low capacitive loading.
