Product Overview
The HT-10XX is a photoelectric coupler designed with a light-emitting diode and phototransistor, housed in a 4-pin LSOP 4 package. It offers high input-output isolation voltage of 5,000Vrms and an 8mm long creepage distance. Key features include a current transfer ratio (CTR) of MIN. 50% at IF = 5mA, VCE = 5V, and a wide operating temperature range of -55 to 110. This device is suitable for applications such as programmable controllers, switching power supplies, intelligent meters, and various home appliances including air conditioners, fans, and water heaters. It holds safety approvals from UL 1577, VDE DIN EN60747-5-5 (VDE 0884-5), and CQC11-471543-2022, and is RoHS and MSL1 compliant.
