| STTH212 High voltage ultrafast diode Main product characteristics A K IF(AV) VRRM Tj VF (typ) trr (max) 2A 1200 V 175C 1.0 V 75 ns DO-201AD STTH212 Features and benefits Low forward voltage drop High reliability High surge current capability Soft switching for reduced EMI disturbances Planar technology SMB STTH212U SMC STTH212S Description The STTH212, which is using ST ultrafast high voltage planar technology, is specially suited for free-wheeling, clamping, snubbering, demagnetization in power supplies and other power switching applications. Housed in axial, SMB, and SMC packages, this diode will reduce the losses in high switching freqency operations.
