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
