Alternistor Triacs
(6 A to 40 A) RoHS

E4
General Description
Teccor offers bidirectional alternistors with current ratings from Variations of devices covered in this data sheet are available for
6 A to 40 A and voltages from 200 V to 1000 V as part of Tec- custom design applications. Consult the factory for further
cor's broad line of thyristors. Teccor's alternistor is specifically information.
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- Features
term reliability and parameter stability. Teccor's glass-passivated
• RoHS Compliant
junctions offer a reliable barrier against junction contamination.
• High surge current capability
Teccor's TO-218X package is designed for heavy, steady power- • Glass-passivated junctions
handling capability. It features large eyelet terminals for ease of
• 2500 V ac isolation for L, J, and K Packages
soldering heavy gauge hook-up wire. All the isolated packages
• High commutating dv/dt
have a standard isolation voltage rating of 2500 V rms.
• High static dv/dt
