SCR  
RoHS  
S4040xQx Series  
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  
• Surge capability up to  
520 A  
• Glass – passivated  
junctions  
•

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 th
e
T
hyristor. 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.
