Procurement Notes

Verify the specific suffix LXHF against the manufacturer's official documentation to confirm RoHS compliance and halogen-free status. Ensure the ordering code matches the exact package variant required for your PCB footprint. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a dual NPN switch with fixed bias is required. Verify that the integrated resistor values meet the base drive requirements of your application. Consider the thermal performance and power dissipation limits relative to the expected operating conditions and ambient temperature.

Part Context

This part belongs to Toshiba's digital transistor series, which combines transistors and resistors into single packages. These devices are designed to reduce wiring complexity and improve switching speed compared to discrete resistor-transistor combinations. The series is widely used in consumer and industrial electronics for signal switching and level shifting.

Replacement Considerations

Check for direct pin-compatible alternatives from other manufacturers offering similar NPN dual configurations with comparable Vceo and Ic ratings. Verify that the replacement's internal resistor ratios match the original design requirements to ensure proper biasing.
