K

Teccor® brand Thyristors

15 and 16 Amp Standard SCRs

Description

Excellent unidirectional switches for phase control
applications such as heating and motor speed controls.

Standard phase control SCRs are triggered with few
milliamperes of current at less than 1.5V potential.

Applications

Typical applications are capacitive discharge systems for
strobe lights, nailers, staplers and gas engine ignition. Also
controls for power tools, home/brown goods and white
goods appliances.

Internally constructed isolated packages are offered for
ease of heat sinking with highest isolation voltage.
