?FEATURES
@Excellent clamping voltage characteristic and fast response time (<50 ns) when subjected to impulse surges.
@No follow current.
@Any voltage rating within a V1mA range from 200 to 1,100V available. (V1mA : varistor voltage.)
@Bilateral and symmetrical V- I characteristics curve.
@The TNR can, therefore, be used both in AC and DC circuits, for protection of either positive or negative transients.
@Large withstanding peak current 8,000 to 25,000A(8/20Ms).
?APPLICATIONS
@Protection of semiconductors such as transistors, diodes, ICs, thyristors, triacs, etc.
@Protection of various equipment including:
@Surge absorption of relays and electromagnetic valves.
@Absorption of surges generated within equipment such as TVs.
?DIMENSIONS [mm (in.)]
?STANDARD RATINGS
*Broadcasting, communications equipment.
*Traffi c and railway signal systems.
*Automatic control devices for power distribution.
*Waterworks.
*Home entertainment equipment.
