BO — Breakover current 50/60 Hz sine wave
(8) For best sidac operation, the load impedance should be near or
less than switching resistance.
DRM — Repetitive peak off-state current 50/60 Hz sine wave; V = VDRM
H — Dynamic holding current 50/60 Hz sine wave; R = 100 Ω
T(RMS) — On-state RMS current TJ ≤ 125 °C 50/60 Hz sine wave
(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.
