Applications
• Programmable Logic Controllers (PLCs) • Air Conditioner Inverters
2.
General
TLP388 consists of phototransistors optically coupled to infrared LED.
The TLP388 is housed in the thin SO6L (4 pin) package and that guarantees high temperature operation (Ta = 125 max) .
With the high brakedown voltage between the collector and emitter (VCEO) 350 V, TLP388 is suitable for use in programmable logic controllers (PLCs), and home appliances, include air conditioners.
