STMicroelectronics announces high-gain, low-loss bipolar power transistor providing high-efficiency edge.Business Editors/High Tech Writers Geneva--(BUSINESS WIRE)--Aug. 6, 2001 STMicroelectronics (NYSE NYSE See: New York Stock Exchange : STM (Scanning Tunneling Microscope) A microscope that can image down to the atomic level. An STM uses a piezoelectric tube with a tiny sharp tip at the end that is moved within nanometers of the object being sampled. ) has introduced the first in a family of very high-gain bipolar power transistors that feature extremely low saturation voltage, making it well suited for highly efficient low-voltage switching applications. Typical uses for the STT STT State Street Corporation (stock symbol) STT Suomen Tietotoimisto (Finnish National News Agency) STT Secure Transaction Technology STT Surface Tension Transfer (welding) 818A/B A/B Airborne A/B Afterburner (jet engines) A/B Air Blast A/B Answerback A/B Auto-brake A/B Air Bus A/B Afterburning low-voltage, high-gain power transistors include power management in portable equipment and switching regulators in battery chargers. The STT818A/B high-gain PNP power transistor, using an inter-digitated layout, harnesses the latest low-voltage epitaxial planar technology. As a result, the bipolar transistor exhibits a typical collector-emitter saturation voltage of 0.25V (for IC=2A and IB=20mA), thus capping conduction losses. With a minimum DC current gain (hFE) of 100 and a typical value of 200, the STT818A minimizes current requirements. The STT818A also carries a continuous collector current (Ic) of 3A. The STT818A/B high-gain PNP power transistor comes in a SOT23-6L package in tape-and-reel format.
