APPLICATION 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

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.
