12 Amp Standard SCRs
Sxx12x Series
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.
Features & Benefits
• RoHS compliant
• Voltage capability up
to 1000 V
• Glass – passivated
junctions
• Surge capability up to
120 A
Applications
Main Features
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.

Design Considerations
1008 hours; -40°C
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 theThyristor. 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,
overvoltage (including dv/dt), and surge currents are
the main killers of semiconductors. Correct mounting,
soldering, and forming of the leads also help protect
against component damage.
