STMicroelectronics has introduced five power-semiconductor bridges in popular configurations, housed in ST’s advanced ACEPACK™ SMIT package that eases assembly and enhances power density over conventional TO-style packages.
Engineers can choose from two STPOWER 650V MOSFET half bridges, a 600V ultrafast diode bridge, a 1200V half-controlled full-wave rectifier, and a 1200V thyristor-controlled bridge leg. All devices meet automotive-industry requirements and are suitable for electric vehicle on-board chargers (OBC) and DC/DC converters, as well as industrial power conversion.
ST’s ACEPACK SMIT surface mounted package delivers the easy handling of an insulated package with the thermal efficiency of an exposed drain. It allows direct-bonded copper (DBC) die attachment for efficient top-side cooling. The 4.6 cm2 exposed metal topside of the ACEPACK SMIT permits easy attachment of a planar heatsink. This creates a space-saving low profile that maximizes thermal dissipation for greater reliability at high power. The module and heatsink can be placed using automated inline equipment, which saves manual processes and boosts productivity (more info).
