Full series of silicon-controlled rectifiers in standard TO-220A packages
America Semiconductor has introduced the ASCT625A Series of
silicon-controlled rectifiers (SCRs). The 25A, single-phase SCRs are
provided in a standard TO-220A package, and feature a high ability to
withstand the shock loading of large current. The robust parts additionally
provide high dv/dt capabilities and a strong resistance to electromagnetic
The devices are ideal for a broad range of high-reliability consumer and
industrial applications such as in solid-state relays, motorcycles, power
chargers and power tools.
The parts feature a repetitive peak off-state voltage and repetitive peak
reverse voltage of 600V. Additional electrical characteristics include a
maximum on-state voltage 1.6V, continuous DC gate trigger current of 40mA,
and peak surge (non-repetitive) on-state current of 300A. The rectifiers
also feature a maximum operating junction temperature range of -40C to 125C
and maximum storage junction temperature range of -40C to 150C. DC holding
current is 50mA.
