In a move to provide a low-cost alternative to synchronous rectification solutions, Vishay Intertechnology launched what’s said to be the industry's first 200V, 30A dual high-voltage TMBS Trench Schottky rectifier.
The V30200C offers several advantages over planar Schottky rectifiers. As operating voltages move to 100V and above, planar Schottky rectifiers tend to lose their advantage of high switching speed and low forward voltage drop to a substantial degree. The patented TMBS structure, however, diminishes minority carrier injections to the drift region, minimizing stored charges and improving switching speed.
With an very low VF of 0.648V typical at 15A and +125°C, and superior switching performance, the V30200C reduces power loss and improves the efficiency of switchmode power supplies and OR-ing diodes. To lower costs by reducing the component count and saving board space, the rectifier can be used as an alternative to synchronous rectification solutions while matching their efficiency and thermal performance.
The device is optimized for consumer and computer applications with power ratings from 80 to 200W, including high-power, high-efficiency telecom base station power supplies; OR-ing diodes for redundant switchmode power supplies in servers and industrial PCs; secondary rectification circuits for switchmode power supply adaptors in desktop PCs, servers, and notebook PCs; and adaptors for high-power plasma display panels (PDP) TVs, LCD TVs, and LCD monitors.
