Vishay Semiconductor HEXFRED
Ultrafast Diodes & Rectifiers
Vishay Semiconductors HEXFRED Ultrafast Diodes & Rectifiers feature extremely low values of peak recovery current (IRRM) and does not exhibit any tendency to "snap-off" during the tb portion of recovery. These HEXFRED features combine to offer designers a rectifier with lower noise and significantly lower switching losses in both the diode and the switching transistor. These advantages can help to significantly reduce snubbing, component count and heatsink sizes. The HEXFRED is ideally suited for applications in power supplies and power conversion systems (such as inverters), motor drives, and many other similar applications where high speed, high efficiency is needed.
