Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required packaging format. Ensure compliance with RoHS directives and check for any end-of-life notices prior to procurement decisions.

Selection Notes

Select this component when a dual NPN configuration with integrated base resistors is required in a small outline package. Consider the 50 V voltage rating and 100 mA current capacity against circuit demands. Verify thermal management requirements given the 150 mW power dissipation limit in the SOT-563 form factor.

Part Context

This part belongs to ROHM's series of complex digital transistors designed for space-constrained applications. It consolidates discrete transistor and resistor functions into a single surface-mount device, reducing board space and assembly complexity compared to using separate components.
