The Sxx15x and Sxx16x Seres provide excellent
unidirectional switching 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.
Features & Benefits
• RoHS-compliant
• Glass – passivated
junctions
• Voltage capability up
to 1000 V
• Surge capability up to
225 A
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.

Design Considerations
Careful selection of the correct device for the application’s
operating parameters and environment will go a long way
toward extending the operating life of the Thyristor. Good
design practice should limit the maximum continuous
current through the main terminals to 75% of the device
rating. Other ways to ensure long life for a power discrete
semiconductor are proper heat sinking and selection of
voltage ratings for worst case conditions. Overheating,
