Product Description

Product Overview

The HT-817X is a photoelectric coupler from Hengtuo Technology Co., LTD., designed with a light-emitting diode and a phototransistor. It is available in a 4-pin package with options for wide-lead spacing and SMD. Key features include a high current transfer ratio (CTR MIN. 50%), high input-output isolation voltage (Viso = 5,000Vrms), and a wide operating temperature range of -55 to 110. The HT-817X is certified with UL 1577, VDE DIN EN60747-5-5, and CQC11-471543-2022, and is RoHS and MSL1 compliant. It is suitable for applications such as programmable controllers, switching power supplies, intelligent meters, and home appliances including air conditioners, fans, and water heaters.
