ST offers ultrafast diodes from 200 to 1200 V with various VF/trr trade-offs to achieve the best performance for any application.
In PFC and solar inverters, ST has introduced the second generation of tandem diodes that offer a cost-efficient alternative to SiC technology.
All ST products are rated up to 175 °C operating junction temperature, as a result of the reduced leakage currents.
W series of ultrafast diodes for welding applications
ST's W series of ultrafast STTH rectifiers have been designed to offer the perfect trade-off between a low forward voltage (VF) and a short reverse recovery time (trr), leveraging a long experience with market leaders in the welding industry. The reduced conduction in the diodes significantly reduces power losses in the high-power secondary rectification stage. Using platinum doping, the new W series of high-current diodes, from 20 to 200 A, are ideal for the latest requirements in welding equipment.
