Diode Arrays Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options and packaging format. The 'TR' designation indicates tape and reel packaging, while 'PBFREE' confirms lead-free composition. Confirm availability through authorized distributors as supply status may vary. Ensure the component matches the required SOT-563 footprint and pinout configuration for your PCB layout.

Diode Arrays Selection Notes

Select this component when a compact solution for dual opposing diodes is required in high-speed switching environments. The SOT-563 package offers space efficiency compared to discrete components. Consider the 120 V reverse voltage rating and low junction capacitance for circuit compatibility. Verify thermal resistance requirements against the 500 °C/W specification for your operating conditions.
