The PBSS4230PAN,115 is a dual NPN low VCEsat Breakthrough In Small Signal (BISS) transistor manufactured by Nexperia. It is housed in a leadless DFN2020-6 (SOT1118) surface-mount package with dimensions of 2 x 2 x 0.65 mm. The device features a collector-emitter voltage (VCEO) of 30 V and a continuous collector current (IC) rating of 2 A per transistor. Peak collector current (ICM) reaches 3 A for single pulses up to 1 ms. The collector-emitter saturation resistance (RCEsat) is typically 145 mΩ at IC = 1 A and IB = 0.1 A. The transition frequency (fT) is typically 120 MHz.

Select this component when a dual NPN configuration with low saturation voltage is required in a compact footprint. The DFN2020-6 package offers thermal efficiency suitable for space-constrained designs. Ensure the application current does not exceed the 2 A continuous or 3 A peak ratings under specified thermal conditions.
This part belongs to the Nexperia BISS transistor family, designed for low power consumption and high efficiency. Complementary configurations include the NPN/PNP PBSS4230PANP and the PNP/PNP PBSS5230PAP. These devices utilize innovative mesh-emitter technology to minimize heat generation while maintaining high current handling capabilities.
Direct pin-compatible replacements within the same package are limited. Evaluate the PBSS4230PANP if a complementary NPN/PNP pair is needed instead of two NPN transistors. Verify thermal dissipation requirements against alternative packages like SOT363 or SOT723 if higher power handling is necessary.
