Zetex Unveils ZXTD4591AM832 and ZXMC3AM832

Zetex plc (Chadderton, Oldham) introduced complementary dual bipolar and MOSFET parts, the ZXTD4591AM832 and ZXMC3AM832, in its 3mm x 2mm x 1mm micro leaded package (MLP). Used in push-pull circuit topologies, the transistor pairings create low-cost, high-performance power MOSFET gate drivers.

Providing the requisite high-pulse current and fast switching, the ZXTD4591AM832 offers a 40V rated NPN and PNP combination supporting a continuous collector current of 2.5A, and a maximum saturation voltage of 500mV. Specified up to 2A, the gain of the two transistors is also high, respectively 200 and 160 at 1A collector current.

The MOSFET-equivalent ZXMC3AM832 package, houses complementary 30V trench MOSFETs that combine low on-resistance with enhanced rise and fall times suiting high-efficiency power MOSFET driving. Maximum RDS(on) values for n- and p-channel devices are just 0.12 Ohms and 0.21 Ohms with drain current capabilities of 3.7A and 2.7A.
