FEATURES
BIDIRECTIONAL CROWBAR PROTECTION BETWEEN TIP AND GND, RING AND GND AND BETWEEN TIP AND RING. PEAK PULSE CURRENT : IPP = 30A for 10/1000µs surge. HOLDING CURRENT : IH = 150mA. AVAILABLEIN SO8 PACKAGES. LOW DYNAMIC BREAKOVER VOLTAGE. DESCRIPTION
Dedicated to telecommunication equipment protection, these devices provide a triple bidirectional protection function. They ensure the same protection capability with the same breakdown voltage both in longitudinal mode and transversal mode. A particular attention has been given to the internal wire bonding. Dynamic characteristics have been defined for several types of surges, in order to meet the SLIC maximum ratings.
