Alternistor Triacs
(6 – 40 Amps)

General Description
Teccor offers bidirectional alternistors with current ratings from
6 to 40 amperes with voltages from 200 to 800 volts as part of
Teccor's broad line of thyristors. Teccor's alternistor has been
specifically designed for applications which are required to switch
highly inductive loads. To accomplish this, a special chip has
been designed which effectively offers the same performance as
two thyristors (SCRs) wired inverse parallel (back-to-back);
hence, the alternistor has better turn-off behavior than a standard
triac. An alternistor may be triggered from a blocking to conduc-
tion state for either polarity of applied AC voltage with operating
modes in Quadrants I, II, and III.
This new chip construction provides two electrically separate
SCR structures, providing enhanced dv/dt characteristics while
retaining the advantages of a single chip device.
All alternistors have glass-passivated junctions to ensure long
term reliability and parameter stability. Teccor's glass offers a reli-
able barrier against junction contamination.
These alternistors are offered in four basic package configura-
tions: TO-218X, TO-218AC, FastPak, and TO-220AB. Teccor's
TO-218X package has been designed for heavy, steady power-
handling capability. The TO-218X features large eyelet terminals
for ease of soldering heavy gauge hook-up wire. All the isolated
packages have a standard isolation voltage rating of 2500V
RMS
.
Variations of devices covered in this data sheet are available for
custom design applications. Please consult factory for further
information.

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 I
GT
rat-
ing with a steep rising waveform (≤1µs rise time).

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.
