Overview
The PMBT3946YPN-QX is a dual NPN/PNP general-purpose transistor manufactured by Nexperia. It integrates one NPN and one PNP bipolar junction transistor within a single SOT363 (SC-88) surface-mount package. The device supports a maximum collector current of 200 mA and operates with a collector-emitter voltage of 40 V. Key electrical parameters include a gain-bandwidth product of 300 MHz, power dissipation of 350 mW, and a DC current gain minimum of 30. The component functions across an operating temperature range from -55°C to +150°C.
Feature Summary
- Dual configuration combining NPN and PNP transistors for board-space reduction
- Qualified according to AEC-Q101 standards for automotive reliability
- General-purpose switching and amplification capabilities
Applications
- General-purpose switching circuits
- Amplification stages in portable equipment
- Automotive digital applications
Procurement Notes
Verify the suffix 'QX' against official Nexperia documentation to confirm specific reel packaging or tape-and-reel specifications distinct from standard variants. Ensure the order matches the exact part number to guarantee AEC-Q101 qualification status and correct pinout alignment for the SOT363 package during assembly.
Selection Notes
Select this component when space-constrained designs require both NPN and PNP switching functions in a single footprint. The 40 V rating and 200 mA current capacity suit low-power signal processing tasks. Verify thermal management requirements given the 350 mW power dissipation limit in the small SMD plastic package.
Part Context
This part serves as the NPN/PNP complement to the PMBT3906YS (PNP/PNP) and PMBT3904YS (NPN/NPN) series. All variants share the same SOT363-3 package dimensions, facilitating design flexibility while maintaining consistent board layout constraints for mixed-polarity transistor pairs.
Replacement Considerations
Direct functional substitutes include PMBT3946YS and PMBT3946T, which offer identical NPN/PNP configurations in compatible packages. Verify pin compatibility and electrical ratings before substitution.
