Product Description
Product Overview
The PC-357X is a photoelectric coupler designed with an integrated light-emitting diode and phototransistor. Available in a 4-pin package with wide-lead spacing and SMD options, it offers high input-output isolation voltage (3,750Vrms) and a wide operating temperature range of -55 to 110. Key features include a minimum current transfer ratio (CTR) of 50% at IF = 5mA, VCE = 5V, and compliance with safety approvals such as UL 1577, VDE DIN EN60747-5-5, and CQC11-471543-2022. It is also RoHS and MSL1 compliant. The PC-357X is suitable for applications including programmable controllers, switching power supplies, intelligent meters, and various home appliances like air conditioners, fans, and water heaters.
