Procurement Notes

Verify the specific ordering suffix '-13' confirms the Tape & Reel packing quantity of 10,000 units. Ensure the component meets RoHS 3 and Halogen-free requirements if mandated by your design specifications. Confirm that the SOT563 package dimensions align with your PCB footprint constraints. Validate that the -30V voltage rating is sufficient for your specific circuit's maximum operating conditions.

Selection Notes

Select this component when space-constrained designs require dual p-channel switching capabilities. The low input capacitance and fast switching speed make it suitable for high-frequency applications. Consider the RDS(on) values at your intended gate drive voltage (-4.5V or -10V) to ensure acceptable conduction losses. Verify thermal management capabilities given the junction-to-ambient resistance limits.

Part Context
