12 Amp Standard SCR
SRR6012xx Series
RoHS
Description
Excellent unidirectional switches for phase control and
general switching applications such as heating, motor
control controls, converters / rectifiers and capacitive
discharge ignitions.
Sensitive gate SCRs are easily triggered with microAmps
of current as furnished by sense coils, proximity switches,
and microprocessors.
Standard phase control SCRs are triggered with few
milliamperes of current at less than 1.5V potential.

Design Considerations
High Temp Storage
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,
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.
