- ms MATCHED DIODES FOR TYPICAL PFC APPLICATION WITHOUT VOLTAGE BALANCE NETWORK. - a UL PENDING DEVICE : INSULATED VOLTAGE = 2500VRms). ## DESCRIPTION The TURBOSWITCH "H" is) an ultra high performance diode composed of two 300V dice in series . TURBOSWITCH "H" family drastically cuts losses in the associated MOSFET when run at high dir/at. ## ABSOLUTE RATINGS (limiting values for both diodes in series) |ABSOLUTE RATINGS (limiting values for both diodes in series)|ABSOLUTE RATINGS (limiting values for both diodes in series)|ABSOLUTE RATINGS (limiting values for both diodes in series)|ABSOLUTE RATINGS (limiting values for both diodes in series)| |---|---|---|---| |Symbol]Parameter
