APPLIACTION NOTES
• 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 W for 1 ms. The response time of
TVS diode clamping action is effectively instantaneous
(1 x 10-9 s bi-directional); 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.
