sidac (79 v to 330 v) e9 general description the sidac is a silicon bilateral voltage triggered switch with greater power-handling capabiliti es 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 continues until the current is interrupted or drops below the minimum holding current of the device. teccor?s sidacs feature glass-passivated junctions to ensure a rugged and dependable device capable of withstanding harsh environments. variations of devices covered in this data sheet are available for custom design applications. consult the factory for more informa- tion. r o h s applications ? high-voltage lamp ignitors ? natural gas ignitors ? gas oil ignitors ? high-voltage power supplies ?xenon ignitors ? overvoltage protector ? pulse generators ? fluorescent ligh ting ignitors ? hid lighting ignitors features ?rohs compliant ? ac circuit oriented ? glass-passivated junctions ? high surge current capability to-92 type 70 do-214 surface mount to-202 do-15x product specification 1 of 3 4008-318-123 sales@twtysemi.com http://www.twtysemi.com

(8) for best sidac operation, the load impedance should be near or less than switching resistance. (9) see package outlines for lead form configurations. when ordering special lead forming, add type number as suffix to part number. (10) do not use electrically conne cted mounting tab or center lead. (11) the k2401f1 sidac is designed to ensure good commutation at higher switching frequencies, as requ ired in ignitor circuits for high intensity discharge (hid) lighting. a typical circuit for a metal halide lamp ignitor is shown in figure e9.17. with proper component selection this circuit will produce th ree pulses for ignition of osram lamp types such as hqi-t70w, hqi-t150w, and hqi-t250w which require a minimum of three pulses at 4 kv magnitude and >1 s duration each at a minimum repetition rate of 3.3 khz. v-i characteristics type part no. i t(rms) v drm v bo i drm i bo i h to-92 do-15x (10) to-202 do-214 (6) (7) (8) amps volts (1) volts amps (2) amps (3) (4) mamps see ?package dimensions? section for variations.
