nte6415 thru NTE6419 bidirectional thyristor diodes (sidac) description: the nte6415 through NTE6419 sidac devices are silicon bilateral voltage triggered switches with greater power handling capabilities than standard diacs. upon application of a voltage exceeding the sidac breakover voltage point, the sidac switches on through a negative resistance region to a low on?state voltage. conduction will continue until the current is interrupted or drops below the minimum holding current of the device. features: especially effective in ac circuits switching function directly with the ac power line applicable for various pulse generators applications: high voltage lamp ignitors natural gas ignitors gas oil ignitors high voltage power supplies xenon ignitors overvoltage protection pulse generators fluorescent lighting ignitors absolute maximum ratings: peak off voltage, v drm nte6415, nte6416 45v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . nte6417, nte6418, NTE6419 90v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . effective current (t a = +40 c, 50hz, sine wave, conducting angle = 180 ), i t 1a . . . . . . . . . . . . . . surge current (50hz, non?repeated 1 cycle sine wave, peak value), i tsm 13a . . . . . . . . . . . . . . . peak current (t a = +40 c, pulse width = 10 s, f = 1khz), i trm 20a . . . . . . . . . . . . . . . . . . . . . . . . . . current rise rate, di/dt 50a/ s . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . maximum operating junction temperature, t j +125 c . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . storage temperature range, t stg ?30 to +125 c . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . thermal resistance, junction?to?case, r thjc 15 c/w . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . lead temperature (during soldering, 5mm from case, 5sec max), t l +250 c . . . . . . . . . . . . . . . . . .
