The SKT 100/04 D with Thyristor stud, 400V, Ifmax: 175A, 100A; Igt: 150mA, TO209,TO94 manufactured by Semikron is a two-terminal, sealed, zero-crossing, glass-passivated, Thyristor power control device. This Thyristor is suitable for operation in various industrial, commercial and residential applications for controlling power pulses of up to 100 amps and up to 400 volts. The semiconductor chip and stud are insulated by a glass layer which helps provide high current flow capabilities and also protection against contamination and accidental short circuits. Its SCRs—Silicon-controlled Rectifiers—are rated for an Ifm of 175 Amps and an Igt of 150mA. Its package type is TO209 or TO94.
