Technical content
LTV-356T is a small shape chip optoelectronic coupling device, suitable for surface mount production. LTV-356T is a optocoupler composed of a GaAs light- emitting diode and a phototransistor. Its volume is smaller than dip, and it is suitable for high-density surface mount applications, such as programmable logic controller. Characteristic Current conversion ratio (CTR) range: 50 ~ 600% (if = 5mA, VCE = 5V) Input output isolation voltage (VISO = 3750 VRMs) Collector Emitter Breakdown Voltage BVCEO ≥ 80V Working temperature: - 55 - 110 °C Switching power supply, smart meter Industrial control, measuring instruments Office equipment, such as copiers Such as household appliances, fans, etc Para meter Symbol Rating Company Input Forward current I F 50 mA Forward pulse current IFP 1 A Reverse voltage VR 6 V power waste P 70 mW Junction temperature Tj 125 °C Outpu t Collector power consumption PC 150 mW Collector current I C 50 mA Collector Emitter Voltage VCEO 80 V Emitter collector voltage VECO 7 V Junction temperature Tj 125 °C Total power consumption Ptot 200 mW Isolation voltage Viso 3750 Vrms working temperature Topr - 55~+110 °C Storage temperature Tstg - 55~+125 °C welding temperature Tsol 260 °C www.umw-ic.com 1 UTD Semiconductor Co.,Limited UMW R LTV-356T Structural schematic diagram 1.
