12 Amp High Junction Temperature SCRs
SJxx12xx series
RoHS
Description
This SJxx12xx high junction temperature SCR series is
ideal for uni-directional switch applications such as phase
control in heating, motor speed controls, converters/
rectifiers, inrush current control and capacitive discharge
ignitions.
These SCRs have a low gate current trigger level of 6mA,
10mA or 20mA maximum at approximately 1.5V.

Design Considerations
High Temp Storage
Careful selection of the correct component 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 component 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.
