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
