Overview
The PMBT3946YPN is a general-purpose NPN/PNP double transistor manufactured by Nexperia, housed in a SOT363 (SC-88) surface-mount package. It features a maximum collector-emitter voltage of 40 V and a continuous collector current of 200 mA per transistor. The device has a total power dissipation of 350 mW at 25 °C ambient temperature. Key electrical characteristics include a DC current gain (hFE) ranging from 100 to 300 for the NPN transistor and 100 to 300 for the PNP transistor at specified conditions. Transition frequencies are rated at 300 MHz for the NPN and 250 MHz for the PNP transistor.

Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm availability and exact specifications. Confirm RoHS compliance status directly with the supplier or through the latest product data sheet before finalizing procurement decisions.
Selection Notes
Select this component when space-constrained designs require dual complementary transistors in a single package. Ensure the operating voltage does not exceed 40 V and the collector current remains within the 200 mA limit. Consider the thermal resistance values if high-power dissipation is expected in the application.
Part Context
This part belongs to the PMBT3946 series of general-purpose double transistors. Complementary configurations include the PMBT3904YS for NPN/NPN pairs and the PMBT3906YS for PNP/PNP pairs. The SOT363 package allows for efficient PCB layout in portable and automotive devices requiring minimal footprint.
Replacement Considerations
Direct substitutes may include PMBT3946YPN,115 or PMBT3946YPN,125 from Nexperia, provided the pinout and electrical ratings match the design requirements. Verify compatibility with existing footprints and thermal management strategies.
