8 Amp High Temperature Sensitive & Standard SCRs
SJxx08xSx & SJxx08xx Series
RoHS
Description
This SJxx080xx high temperature SCR series is ideal for
uni-directional switch applications such as phase control
in heating, motor speed controls, converters/rectifiers and
capacitive discharge ignitions.
These SCRs have a low gate current trigger level of 6mA
or 15mA maximum at approximately 1.5V, with a sensitive
version of this series having a gate trigger current less than
200µA. The sensitive gate SCR version is easily triggered
by sense coils, proximity switches, and microprocessors.

Design Considerations
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.
