PBSS5320X is a PNP low VCEsat (BISS) transistor produced by Philips Semiconductors. It has a SOT89 (SC-62) package, low collector-emitter saturation voltage VCEsat, high collector current capability: IC and ICM, higher efficiency leading to less heat generation, and reduced printed-circuit board requirements. Applications include power management, DC/DC converters, supply line switching, battery charger, LCD backlighting, etc.
