characteristic after reaching the current limit, and therefore

doesn’t protect against DC and low frequency stresses

(typically achieved through the use of a transformer or

capacitive coupling). This is analogousto comparing the shunt-

ing characteristics of a Transient Voltage Suppressor device to

device have limited or no foldback characteristic, and therefore

have relatively low short term surge energy limits. When used

together in a protection circuit, the surge must not exceed the

thermal capability of either device. The following three graphs

show the maximum surge duration with respect to voltage of the

three TCS-DL devices at both +25 °C and +85 °C.
