40 Amp High Temperature Low Tq SCR
RoHS
HS4040xAQx Series
Description
The HS4040xAQx series of SCRs offer fast turn-off time
(tq) characteristics required for applications such as power
inverters, switching regulator, and high frequency pulse
circuits.
These fast turn-off time SCRs offer high dv/dt and
high
di/dt characteristics required in higher frequency
(>1000 PPS) switching circuits and a higher temperature
environment.

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,
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.
