ROHM Semiconductor GmbH PNP, SOT-457T, -12V -6A, Low VCE(sat) Transistor QST2

The QST2 is a PNP silicon transistor in the TSMT6 package, designed for low-frequency amplification and driver applications. It has a collector-emitter voltage rating of -12 V, a collector current of -3 A, and a collector-emitter saturation voltage of -250 mV at -3 A collector current and -60 mA base current. The device supports a maximum power dissipation of 1.25 W and a junction temperature range of -55 to +150 °C. It complies with RoHS standards. The TSMT6 package measures 2.8 mm × 1.6 mm × 0.92 mm with 6 pins. The transistor has a DC current gain (hFE) of 270 to 680 at -500 mA collector current and -2 V collector-emitter voltage, and a transition frequency of 250 MHz. The part is available in tape and reel packaging with 3000 pieces per reel.
