Description
The S4040xQx 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.
Features & Benefits
• RoHS compliant
• Glass – passivated
junctions
• Voltage capability up
to 400 V
• S urge capability up to
520 A
• TO-220 and TO-263
packages
Unit Applications
A
V
Fast turn-off time SCRs are ideal for multi phase voltage
regulator circuits, DC/AC inverters, and higher frequency
mA pulsing power supplies.

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.
