Vishay Intertechnology, Inc.（NYSE 股市代号：VSH）在提供同步整流解决方案的低成本替代产品进程中宣布推出业界首款 200V、30A 双高压 TMBS® Trench 肖特基整流器。
V30200C 具有比平面肖特基整流器更出色的多种优势。当工作电压转向 100V 及更高时，平面肖特基整流器的高转换速度及低正向压降优势往往会大大折扣。但已获专利的 TMBS 结构可消除到漂移区的少数载流子注入，从而最大程度地减少存储的电荷，以及提高转换速度。
凭借在 15A 及 +125°C 时一般为 0.648V 的极低 VF以及出色的转换性能，V30200C 可降低功耗并提高开关模式电源与 OR-ing 二极管的效率。为通过减少元件数以及节省板面空间来降低成本，该整流器可替代同步整流解决方案，同时可与它们的效率及热性能相媲美。
该器件专为额定功率介于 80W～200W 的消费类及计算机应用而进行了优化，这些应用包括高功率、高效率电信基站电源；用于服务器及工业 PC 中的冗余开关模式电源的 OR-ing 二极管；用于台式电脑、服务器及笔记本电脑中的开关模式电源适配器的二级整流电路；用于高功率等离子 (PDP) 电视、液晶电视及液晶显示器的适配器。
V30200C 采用 TO-220AB、TO-263AB 及 TO-262AA 封装，并且符合 RoHS 2002/95/EC 及 WEEE 2002/96/EC。
Vishay Releases the Industry’s First 200-V Dual High-Voltage TMBS® Trench Schottky Rectifier
The 30-A V30200C Provides Extremely Low VF of 0.648 V In Three Packages to Replace Synchronous Rectification Solutions
In a move to provide a low-cost alternative to synchronous rectification solutions, Vishay Intertechnology, Inc. (NYSE: VSH) launched the industry’s first 200-V, 30-A dual high-voltage TMBS® Trench Schottky rectifier.
The V30200C offers several advantages over planar Schottky rectifiers. As operating voltages move to 100 V 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 extremely low VF of 0.648 V typical at 15 A 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 W to 200 W, 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.
