The QSZ4 is a combined PNP and NPN transistor pair in a TSMT5 package, designed for DC/DC converter and motor driver applications. Each element has a collector-emitter voltage rating of ±30 V, a collector current rating of ±4 A (single pulse, 1 ms), and a total power dissipation of 1.25 W. The junction temperature range is −55°C to +150°C. The PNP transistor has a maximum VCE(sat) of −370 mV at −1.5 A and −75 mA, while the NPN has a maximum VCE(sat) of 370 mV at 1.5 A and 75 mA. Both devices exhibit a DC current gain (hFE) from 270 to 680 at 200 mA and 2 V. The TSMT5 package dimensions are consistent with ROHM's standard for this footprint, and each lead has identical dimensions. The part meets the AEC-Q200 reliability standard and is rated for operation in automotive and industrial environments.
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.
