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:
• Voltage capability up to 400 V
• Surge capability up to 520 A
• TO-220 and TO-263 packages
• RoHS compliant
• Glass – passivated junctions

Applications:
Fast turn-off time SCRs are ideal for multi phase voltage regulator circuits, DC/AC inverters, and higher frequency pulsing power supplies.
