THBT15011D

® THBTxxx11D TRIPOLAR OVERVOLTAGE PROTECTION FOR TELECOM LINE Application Specific Discretes A.S.D.™ 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. The ”4-point” configuration ensures a reliable protection, eliminating overvoltages introduced by the parasitic inductances of the wiring (Ldi/dt), especially for very fast transient overvoltages. Dynamic characteristics have been defined for several types of surges, in order to meet the SLIC maximum ratings.
