600V FRED added to a Family of popular SMPC4.6U packaged devices

Taiwan Semiconductor (TSC), a global supplier of discrete power electronics devices, LED drivers, analog ICs and ESD protection devices, announces an additional 600V Ultra fast diode to the family of SMPC4.6U devices.

The SMPC4.6U wettable flank package FRED device is designed to exceed stringent automotive requirements for reliability and manufacturability. Thermal resistance is reduced by exposed thermal pads increasing contact surface area to transfer heat into the PCB and reducing parasitic DC resistance. SMPC4.6U devices are 64% smaller than a SMC package with greatly improved power density, capable of high temperature operation. Applications in automotive power electronics, industrial and datacom. Samples and complete devices models are available.
