The NCR420PAS-QX is an NPN bipolar junction transistor (BJT) from Nexperia, designed for surface-mount applications in the SOT-1118D (HUSON6) package. It features a maximum collector-emitter voltage of 40 V and a continuous collector current of 250 mA. The device supports a power dissipation of 530 mW and operates within a temperature range of -55 °C to +150 °C. Qualified to AEC-Q101 standards, it serves automotive-grade requirements.
Verify the specific suffix 'QX' against official Nexperia documentation to confirm the reel quantity and tape specifications. Ensure the ordering part number matches the required AEC-Q101 automotive grade designation. Confirm the SOT-1118D package variant aligns with the target PCB footprint before finalizing procurement orders.
Select this component when an NPN BJT with 40 V rating and 250 mA current capacity is required in a compact SMD form factor. The HUSON6 package offers space efficiency compared to larger through-hole alternatives. Consider the 530 mW power dissipation limit for thermal management in dense circuit layouts.
This device belongs to Nexperia's portfolio of discrete semiconductors tailored for robust industrial and automotive environments. The NCR series provides reliable switching performance, while the PAS-QX designation indicates specific automotive qualification and packaging configuration within the broader product line.
