Photoelectric Coupler HENGTUO HT-817S1-CTP1-F with High Isolation Voltage and Wide Temperature Range

Product Overview

The HT-817X is a photoelectric coupler 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% at IF = 5mA, VCE = 5V), high input-output isolation voltage (Viso = 5,000Vrms), and a wide operating temperature range of -55 to 110. The product is certified with UL 1577, VDE DIN EN60747-5-5 (VDE 0884-5), and CQC11-471543-2022, and is RoHS and MSL1 compliant. Applications include programmable controllers, switching power supplies, intelligent meters, and home appliances such as air conditioners, fans, and water heaters.
