Procurement Notes

Verify the specific suffix LXHF(CT) against official Toshiba documentation to confirm packaging type and reel specifications. Ensure compliance with RoHS directives and AEC-Q101 automotive qualification requirements for your target application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components during sourcing.

Selection Notes

Select this component when a single NPN digital transistor with integrated biasing is required for automotive-grade designs. Compare the 4.7 kOhm input resistance and 50 V voltage rating against circuit requirements. Consider the SOT-23 package constraints and 100 mA current limit relative to load demands. Evaluate thermal dissipation needs against the 100 mW power rating for proper heat management.

Part Context
