Thyristor Product Catalog
(10) See Figure E4.12 for tgt versus IGT.
(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 16 A to 40 A devices and
100 mA for 6 A to 12 A devices.
(13) See Figure E4.1 through Figure E4.4 for maximum allowable case
temperature at maximum rated current.
(14) Pulse width
≤10 s; IGT ≤ IGTM
(15) For 6 A to 12 A devices, RL = 60 ; 16 A and above, RL = 30
(16) 40 A 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 A to 12 A devices and 500 mA for 16 A to 40 A
devices with gate pulse having rise time of
≤0.1 s.
(20) Minimum non-trigger VGT at 125 °C is 0.2 V.
Gate Characteristics
Teccor triacs may be turned on in the following ways:
In-phase signals (with standard AC line) using Quadrants I
and III
Application of unipolar pulses (gate always negative), using
Quadrants II and III with negative gate pulses
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 (
≤1 s rise time).
If QIV and QI operation is required (gate always positive), see
Figure AN1002.8, “Amplified Gate” Thyristor Circuit.
Definition of Quadrants
Electrical Isolation
Teccor’s isolated alternistor packages withstand a minimum high
potential test of 2500 V ac rms from leads to mounting tab, over
the operating temperature range of the device. The following iso-
lation table shows standard and optional isolation ratings.
* UL Recognized File E71639
** For 4000 V isolation, use V suffix in part number.
* UL Recognized Product per UL File E71639
** For 4000 V isolation, use V suffix in part number.
