THDT58S

THDT58S1 THDT58S Application Specific Discretes A.S.D.™ FEATURES CROWBAR PROTECTION DUAL ASYMMETRICAL TRANSIENT SUPPRESSOR PEAK PULSE CURRENT : - IPP = 75 A, 10/1000 µs for THDT58S. - IPP = 35 A, 10/1000 µs for THDT58S1. HOLDING CURRENT = 150 mA min BREAKDOWN VOLTAGE = 58 V. BREAKOVER VOLTAGE = 80V max SIP 3 TRANSIENT VOLTAGE SUPPRESSOR FOR SLIC PROTECTION DESCRIPTION This device has been especially designed to protect subscriber line card interfaces (SLIC) against transient overvoltages. Its ion-implanted technology confers its excellent electrical characteristics. This is why this device easily fulfils the main protection standards which are related to the overvoltages suppression on telecom lines. The product pinout is compatible with TO202 and TO220 packages.
