Product Description

Product Overview

The HT-814X is a photoelectric coupler from Hengtuo Technology Co., LTD., designed with two light-emitting diodes and a phototransistor. Packaged in a 4-pin configuration, it offers wide-lead spacing and an SMD option. Key features include AC input response, a current transfer ratio (CTR) of a minimum of 20% at IF = 1mA and VCE = 5V, and high input-output isolation voltage (Viso = 5,000Vrms). It operates within a temperature range of -55 to 110 and holds safety approvals including UL 1577, VDE DIN EN60747-5-5, and CQC. The HT-814X is suitable for applications such as programmable controllers, switching power supplies, intelligent meters, and home appliances like air conditioners, fans, and water heaters.
