SMTHDTXX Datasheet | STMicroelectronics

FEATURES UNDIRECTIONAL CROWBAR PROTECTION. PEAK PULSE CURRENT: IPP = 75 A , 10/1000 µs. HOLDING CURRENT = 150m A. BREAKDOWN VOLTAGE: SMTHDT58 = 58V. SMTHDT80 = 80V. SMTHDT120 = 120V. PACKAGES: SMTHDTxx = SURFACE MOUNT PACKAGE. DESCRIPTION : TRIBALANCED PROTECTION Dedicated protection devices for ISDN LINE CARD and high speed data tele lines. Used with the remended configuration using 3 ponents, they will provide = - Dual bidirectionnal protection, with fixed breakdown voltage in both mon and differential modes. - Low capacitancesfrom lines to ground. - Very good capacitance balance : ∆C= 30 p F.
