For bidirectional types with VR 10 volts and less the ID limit is doubled * Bidirectional versions are UL approved under component across the line protection, ULV1414 file number E108274 (1.5KE200CA, 1.5KE220CA) + UL listed for Telecom applications protection, 497B, file number E136766 for both uni-directional and bi-directional devices APPLICATION This series of Silicon Transient Suppressors is used in applications where large voltage transients can permanently damage voltage-sensitive components. The TVS diode can be used in applications where induced lightning on rural or remote transmission lines presents a hazard to electronic circuitry (ref: R.E.A. specification P.E. 60). This Transient Voltage Suppressor diode has a pulse power rating of 1500 watts for one millisecond. The response time of TVS diode clamping action is effectively instantaneous (1 x 10-9 seconds bidirectional); therefore, they can protect integrated circuits, MOS devices, hybrids, and other voltage sensitive semiconductors and components. TVS diodes can also be used in series or parallel to increase the peak power ratings.
