Now available in the SOT23FF package, Zetex Semiconductors’ miniature bipolar NPN and PNP transistors are well suited for MOSFET gate driving in newer power supplies. The transistors provide lower saturation voltage, higher current gain hold-up, improved circuit efficiency and cooler operation. The footprint measures 2.5 mm × 3mm, with an off-board height of 1 mm. Operating from 20 through 100 V, the transistors drive MOSFET gates faster and more efficiently than CMOS IC alternatives. The ZXTN19020CFF and ZXTP19020CFF 20 V transistors have guaranteed gains of 100 at 7 A and 110 at 5 A, respectively. When connected in a common emitter configuration, they provide extremely fast switching: Propagation times are less than 2ns, and rise and fall times are 10 to 20nsecs. Thermal resistance figures are as low as 83°C/W, with a 1.5 W continuous rating. Immune to latch-up, the transistors offer an improvement in overall system reliability.
