Littelfuse Inc. Q4025J681 is a snubberless Alternistor TRIAC designed for high-power AC switching applications. This single-phase device features a 400V off-state voltage and a continuous on-state current rating of 25A RMS. The Q4025J681 is housed in a TO-218X isolated tab package, facilitating efficient heat dissipation in through-hole mounting configurations. It is specified with a maximum gate trigger current (Igt) of 80mA and a maximum gate trigger voltage (Vgt) of 1.3V, ensuring reliable triggering characteristics. The holding current (Ih) is rated at a maximum of 100mA. For transient immunity, it offers a non-repetitive surge current capability of 208A at 50Hz and 250A at 60Hz. Operating across a temperature range of -40°C to 125°C (TJ), this component is suitable for use in industrial motor controls, lighting controls, and power switching circuits.
