Renesas Electronics Corporation Discrete Semiconductor Products - Transistors - Bipolar (BJT) - Single 2SB1578-T1-AZ

The 2SB1578 is a PNP silicon epitaxial transistor for low-frequency power amplifiers and mid-speed switching, used in DC/DC converters and motor drivers. It comes in a compact package with a maximum collector current of -5.0 A (DC) and -7.0 A (pulse), a collector-emitter voltage rating of -60 V, and a power dissipation of 2.0 W on a 7.5 cm² × 0.7 mm ceramic board. The junction temperature is rated to 150°C. DC current gain ranges from 50 to 400 depending on operating conditions. Collector saturation voltage is -180 mV to -300 mV at -2.0 A collector current and -0.2 A base current. Turn-on time is 0.6 µs, storage time 0.55 µs, and fall time 0.05 µs under specified test conditions. It is assigned the 'Standard' quality grade and has a complementary pair, the 2SD2425.
