Selection Notes
Select this component when space-constrained designs require complementary NPN and PNP transistors in a single package. Ensure the application voltage does not exceed 40 V and current stays within 200 mA limits. Consider thermal derating if operating above 25 °C ambient temperature to maintain reliability within the 350 mW dissipation limit.
Part Context
This part belongs to the PMBT3946YPN family of dual transistors. Complementary configurations include the PMBT3904YS (NPN/NPN) and PMBT3906YS (PNP/PNP). The device is designed for high-volume manufacturing and offers consistent performance across temperature ranges suitable for consumer and industrial electronics.
Replacement Considerations
Direct replacements must match the SOT363 footprint and electrical ratings. Verify pinout compatibility as some dual transistors use different internal arrangements. Check hFE gain ranges and saturation voltages to ensure circuit functionality remains unchanged during substitution.
