Procurement Notes

Verify the specific suffix 'T2R' corresponds to the required tape-and-reel packaging configuration. Confirm that the 30V rating aligns with the target circuit's voltage headroom requirements. Ensure the SOT-563 footprint matches the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when dual PNP switching with integrated base resistors is required. Consider the 22kOhm input resistance for drive current limitations. Evaluate the 150mW thermal dissipation against ambient conditions. Compare against similar ROHM series parts if different resistor values or voltage ratings are needed.

Part Context

This part belongs to ROHM's complex digital transistor family, specifically designed to replace multiple discrete components. It consolidates two transistors and associated biasing networks into a single compact package, reducing board space and assembly complexity compared to traditional discrete solutions.

Replacement Considerations

Check ROHM datasheets for alternative PNP digital transistors with matching 30V ratings and SOT-563 packages. Verify pin compatibility and electrical parameters such as hFE and input resistance before substituting.
