Alternistor Triacs

(6 A to 40 A)

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.
