General Description
The Teccor line of thyristor SCR semi-conductors are half-wave,
unidirectional, gate-controlled rectifiers which complement Tec-
cor's line of sensitive SCRs. Teccor offers devices with ratings of
1 A to 70 A and 200 V to 1000 V, with gate sensitivities from
10 mA to 50 mA. If gate currents in the 12 µA to 500 µA ranges
are required, see “Sensitive SCRs” section of this catalog.
Three packages are offered in electrically isolated construction
where the case or tab is internally isolated to allow the use of
low-cost assembly and convenient packaging techniques.
The Teccor line of SCRs features glass-passivated junctions to
ensure long-term reliability and parameter stability. Teccor’s
glass offers a rugged, reliable barrier against junction contamina-
tion.
Variations of devices covered in this data sheet are available for
custom design applications. Consult the factory for more informa-
tion.
