Specific Test Conditions
di/dt — Critical rate-of-rise of on-state current
dv/dt — Critical rate-of-rise of off-state voltage at rated VDRM;
TJ ≤ 100 °C
dVq/dt — Critical rate-of-rise of turn-off voltage at 8 kHz
IBO — Breakover current 50/60 Hz sine wave
IDRM — Repetitive peak off-state current 50/60 Hz sine wave; V = VDRM
IH — Dynamic holding current 50/60 Hz sine wave; R = 100 Ω
IT(RMS) — On-state RMS current TJ ≤ 125 °C 50/60 Hz sine wave
ITSM — Peak one-cycle surge current 50/60 Hz sine wave (non-
repetitive)
RS — Switching resistance
50/60 Hz sine wave
VBO — Breakover voltage 50/60 Hz sine wave
VDRM — Repetitive peak off-state voltage
VTM — Peak on-state voltage; IT = 1 A
General Notes
All measurements are made at 60 Hz with a resistive load at an
ambient temperature of +25 °C unless otherwise specified.
Storage temperature range (TS) is -65 °C to +150 °C.
The case (TC) or lead (TL) temperature is measured as shown on
the dimensional outline drawings in the “Package Dimensions” sec-
tion 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 maxi-
mum;
≥1/16" (1.59 mm) from case.
Electrical Specification Notes
(1) See Figure E9.5 for VBO change versus junction temperature.
(2) See Figure E9.6 for IBO versus junction temperature.
(3) See Figure E9.2 for IH versus case temperature.
(4) See Figure E9.13 for test circuit.
(5) See Figure E9.1 for more than one full cycle rating.
(6) TC ≤ 90 °C for TO-92 Sidac
TC ≤ 105 °C for TO-202 Sidacs
TL ≤ 100 °C for DO-15X
TL ≤ 90 °C for DO-214
(7) See Figure E9.14 for clarification of sidac operation.
(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.
