Procurement Notes

Verify the specific ordering suffix against official Toshiba documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the AEC-Q101 automotive qualification status aligns with project requirements. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a single NPN configuration with a 1 kOhm base resistor is required. Ensure the 50 V voltage rating and 100 mA current limit meet the load demands. Consider the SOT-723 footprint constraints during PCB layout. Verify thermal management capabilities given the 150 mW power dissipation limit in the target application environment.

Part Context
