S4025NRP Littelfuse

Teccor brand Thyristors 20 / 25 Amp Standard SCRs RoHS Sxx20x & Sxx25x Series Description Excellent unidirectional switches for phase control applications such as heating and motor speed controls. Standard phase control SCRs are triggered with few milliamperes of current at less than 1.5V potential. Features & Benefits RoHS-compliant Surge capability up to 350 A Glass passiv ated junctions A vailable in isolated TO-220, non-isolated Voltage capability up TO-220 and TO-263 to 1000 V packages. Agency Approval Applications Typical applications are AC solid-state switches, industrial Agency Agency File Number power tools, exercise equipment, white goods and E71639* commercial appliances. * - L Package Only Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage.
