The QSZ2 is a monolithic complementary pair of NPN and PNP transistors in a SOT-25T package, designed for low-frequency amplifier and driver applications. The PNP transistor has a collector-emitter voltage rating of -30 V and a collector current of -1.5 A, while the NPN transistor ratings are 30 V and 1.5 A. Collector-emitter saturation voltage is -370 mV maximum for the PNP at -1 A collector current and -50 mA base current, and 350 mV maximum for the NPN at 1 A and 50 mA. Both transistors offer a DC current gain between 270 and 680. The junction temperature range is -55 to +150 °C. Power dissipation is rated at 1.25 W when mounted on a 25 mm × 25 mm × 0.8 mm ceramic board.
Devices integrating two transistors are available in ultra-compact packages, suitable for various applications such as pre-amplifier differential amplification circuits, high-frequency oscillators, driver ICs and so forth.
