E9 DO-15X DO-214 Surface Mount TO-92 Type 70 TO-202 Sidac (79 V to 330 V) RoHS E9 General Description The sidac is a silicon bilateral voltage triggered switch 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 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 information.

(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 connected mounting tab or center lead. (11) The K2401F1 sidac is designed to ensure good commutation at higher switching frequencies, as required 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 three 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 µs duration each at a minimum repetition rate of 3.3 kHz. General Notes +I • All measurements are made at 60 Hz with a resistive load at an ambient temperature of +25 °C unless otherwise specified. IT • Storage temperature range (TS) is -65 °C to +150 °C. IH • The case (TC) or lead (TL) temperature is measured as shown on the dimensional outline drawings in the “Package Dimensions” section of this catalog. • Junction temperature range (TJ) is -40 °C to +125 °C. • Lead solder temperature is a maximum of +230 °C for 10 s maximum; ≥1/16" (1.59 mm) from case.
