General Description
Teccor offers bidirectional alternistors with current ratings from
6 A to 40 A and voltages from 200 V to 1000 V as part of Teccor's
broad line of thyristors. Teccor's alternistor is specifically
designed for applications that switch highly inductive loads.
A special chip offers the same performance as two thyristors
(SCRs) wired inverse parallel (back-to-back), providing better
turn-off behavior than a standard triac. An alternistor may be trig-
gered from a blocking to conduction 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-passivated
junctions offer a reliable barrier against junction contamination.
Teccor's TO-218X package is designed for heavy, steady power-
handling capability. It features large eyelet terminals for ease of
soldering heavy gauge hook-up wire. All the isolated packages
have a standard isolation voltage rating of 2500 V rms.
Variations of devices covered in this data sheet are available for
custom design applications. Consult the factory for further
information.
Features
• High surge current capability
• Glass-passivated junctions

General Notes
• All measurements are made at 60 Hz with a resistive load at an
ambient temperature of +25 °C unless specified otherwise.
• Operating temperature range (TJ) is -40 °C to +125 °C.
• Storage temperature range (TS) is -40 °C to +125 °C.
• Lead solder temperature is a maximum of 230 °C for 10 seconds
maximum ³1/16" (1.59 mm) from case.
• The case temperature (TC) is measured as shown in the dimen-
sional outline drawings. See “Package Dimensions” section.

(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 µs; IGT £ IGTM
(15) For 6 A to 12 A devices, RL = 60 W; 16 A and above, RL = 30 W
(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 µs.
(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 rating
with a steep rising waveform (£1 µs 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.
