SK225LDTP Littelfuse

Thyristors 25 Amp Standard SCRs RoHS SK225xD 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 R oHS compliant Electrically isolated package LD -Package Voltage capability up and UL Recognized for to 1200 V 2500V RMS Surge capability up to 300 A Agency Recognitions Applications Typical applications are AC solid-state switches, industrial Agency Agency File Number power tools, line rectification 50/60Hz. E71639 Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage.
