The Nexperia PMST3904 is an NPN switching transistor designed for general amplification and switching applications. This AEC-Q101 qualified component is housed in a very small SOT323 (SC-70) surface-mounted device (SMD) plastic package, offering a collector current capability of up to 200 mA and a collector-emitter voltage of 40 V. Its PNP complement is the PMST3906.
