Photoelectric Coupler HENGTUO HT-817S1-DTP1 with High Current Transfer Ratio and RoHS Certification
Product Overview
The HT-817X is a photoelectric coupler designed for general use in electronic applications. It comprises a light-emitting diode and a phototransistor, available in a 4-pin DIP package with wide-lead spacing and SMD options. Key features include a high current transfer ratio (CTR MIN. 50% at IF = 5mA, VCE = 5V), high input-output isolation voltage (Viso = 5,000Vrms), and a wide operating temperature range of -55 to 110. The device is certified with UL 1577, VDE DIN EN60747-5-5, and CQC, and is RoHS and MSL1 compliant. Typical applications include programmable controllers, switching power supplies, intelligent meters, and home appliances such as air conditioners, fans, and water heaters.
