Alternistor Triacs
4-4
Teccor Electronics, Inc.
(972) 580-7777
General Notes
All measurements are made at 60Hz with a resistive load at an
ambient temperature of +25°C unless specified otherwise.
Operating temperature range (TJ) is -40°C to +125°C except 0°C to
+125°C for FastPaks.
Storage temperature range (TS) is -40°C to +125°C except -20°C to
+125°C for FastPaks.
Lead solder temperature is a maximum of 230°C for 10 seconds
maximum
≥ 1/16" (1.59mm) from case.
The case temperature (TC) is measured as shown on the dimen-
catalog.

See Figures
4.10 an
d 4.11 for surge rating with specific durations.
(11) See package outlines for lead form configurations. When ordering
special lead forming, add type number as suffix to part number.
(12) Initial on-state current = 400 mA(DC) for 15-40A devices and
100mA for 6-12 Amp devices.
(13) See Figures
4.1 throug
h 4.4 for maximum allowable case temper-
ature at maximum rated current.
(14) Pulse width
≤ 10s.
(15) For 6-12 Amp devices, RL = 60; 15 Amp and above, RL = 30
(16) 40 Amp pin terminal leads on K package can run 100°C to 125°C.
(17) Alternistor does not turn on in Quadrant IV.
(18) Tc = TJ for test conditions in off-state
(19) IGT = 200 mA for 6-12 Amp devices and 500 mA for 15-40 Amp
devices with gate pulse having rise time of
≤ 0.1 microsecond.
Gate Characteristics
Teccor triacs may be turned on in the following ways:
With in-phase signals (using standard AC line) Quadrants I and
III are used.
By applying unipolar pulses (gate always negative)—with nega-
tive gate pulses Quadrants II and III are used.
In all cases, if maximum surge capability is required, gate pulses
should be a minimum of one magnitude above minimum IGT rat-
ing with a steep rising waveform (
≤1s rise time).
Definition of Quadrants
Electrical Isolation
Teccor’s isolated Alternistor packages will withstand a minimum
high potential test of 2500 VAC (RMS) from leads to mounting
tab, over the operating temperature range of the device. See iso-
lation table below for standard and optional isolation ratings.
* For 4000V isolation, use V suffix in part number.
** UL Recognized File E71639
** UL Recognized Product per UL File E71639.
