SUPPRESSOR PEAK PULSE CURRENT:
-IPP=75A, 10/1000μsfor THDT58S.
-IPP=35A, 10/1000μsfor THDT58S1. HOLDING CURRENT= 150 mA min BREAKDOWN VOLTAGE=58V. BREAKOVER VOLTAGE= 80V max
FEATURES
This device has been especially designed to
protect subscriber line card interfaces (SLIC)
against transient overvoltages.
Its ion-implanted technology confersits excellent
electrical characteristics.
Thisis why this device easily fulfils the main
protection standards which are related to the
overvoltages suppressionon telecom lines.
The product pinoutis compatible with TO202 and
TO220 packages.
