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

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.
