march 2006 rev 1 1/11 11 STTH1512 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 packages: dop3i electrical insulation = 2500 v rms capacitance = 12 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) 15 a v rrm 1200 v t j 175 c v f (typ) 1.20 v t rr (typ) 53 ns part number marking STTH1512d STTH1512d STTH1512g STTH1512g STTH1512g-tr STTH1512g STTH1512w STTH1512w STTH1512pi STTH1512pi k a do247 STTH1512w d 2 pak STTH1512g dop3i STTH1512pi k k a a k a a a k to-220ac STTH1512d k www.st.com
