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 r ural 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 semi-
conductors and components. TVS diodes can also be used in series or parallel to increase the peak power ratings.
