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 interference. 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.
