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.
