SK625LDTP Littelfuse

Thyristors 25 Amp Standard SCRs RoHS SK625xD 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 Electrically isolated package LD -Package Voltage capability up and UL Recognized for to 1600 V 2500V RMS Surge capability up to 250 A Applications Agency Recognitions Typical applications are AC solid-state switches, industrial Agency Agency File Number power tools, line rectification 50/60Hz. Internally constructed isolated packages are offered for E71639 ease of heat sinking with highest isolation voltage.
