功率肖特基二极管

意法半导体的功率肖特基二极管具有低压降和可忽略或零恢复的特点。 它们的电压和电流范围分别为15~200V和1~240A,因此满足了从OR-ing和48V转换器到电池充电器和焊接设备的所有应用需求。 改善了它们的雪崩特性,从而提高了稳定性。

最新器件包括60V、80V、120V中VF和IR与200V功率肖特基二极管。

它们提供多种封装选项,包括标准通孔和表面贴装以及新型PowerFLAT™封装,进一步改善了面向太阳能电池板接线盒的30V和45V旁路二极管的功率密度。 意法半导体引入的最新封装为窄引线TO-220AB封装,特别适于半薄型或薄型笔记本电脑适配器。 由于其引线更窄,所以该封装可以完全插入PCB内部。额定电压为60V、80V、100V和120V的功率肖特基整流器已经提供该封装,并且会有更多二极管采用这种封装。

New 200 V power Schottky diodes for LED lighting applications

ST’s STPS2200 2 A, 200 V power Schottky diode is ideal in flyback topologies used for LED bulbs for incandescent bulb replacement. Available in both SMB and SMBflat packages with a thickness of 1 mm, this component is key for PCB integration. For street lighting applications, the STPS2200 used as free-wheeling diode improves the efficiency of the driver circuit of buck topologies.
For higher power applications such as retrofit light tubes, the 2 x 10 A common-cathode STPS20200C provides a higher efficiency than standard ultrafast diodes and helps reduce power consumption in LED lighting SMPS, including forward topologies. The STPS20200C is available in a wide range of packages.
