march 2006 rev 1 1/8 8 stth9012tv ultrafast recovery - 1200 v diode main product characteristics features and benefits ultrafast, so ft recovery very low conduction and switching losses high frequency and/or high pulsed current operation high reverse voltage capability high junction temperature insulated package: electrical insulation = 2500 v rms capacitance = 45 pf description the high quality design of this diode has produced a device with low leakage current, regularly reproducible characteristics and intrinsic ruggedness. these characteristics make it ideal for heavy duty applications that demand long term reliability. such demanding applications include industrial power supplies, motor control, and similar mission-critical systems that require rectification and freewheeling. these diodes also fit into auxiliary functions such as snubber, bootstrap, and demagnetization applications. the improved performance in low leakage current, and therefore thermal runaway guard band, is an immediate competitive advantage for this device. order codes i f(av) 2 x 45 a v rrm 1200 v t j 150 c v f (typ) 1.20 v t rr (typ) 50 ns part number marking STTH9012TV1 STTH9012TV1 stth9012tv2 stth9012tv2 k2 k1 a2 a1 k2 k1 a2 a1 a1 a2 k1 k2 a1 a2 k1 k2 stth9012tv2 STTH9012TV1 isotop www.st.com
