General
TLP188 consists of phototransistors optically coupled to an infrared LED. The TLP188 is housed in the very small and thin SO6(4pin) package and that guarantees high temperature operation(Ta = 110  max). With the high breakdown voltage between the collector and emitter(VCEO = 350 V), TLP188 is suitable for use in programmable logic controllers (PLCs), and home appliances, include air conditioners.

Features
(1) Collector-emitter voltage: 350 V (min)
(2) Current transfer ratio: 50 % (min)
   Rank GB: 100 % (min)
(3) Isolation voltage: 3750 Vrms (min)
(4) Operating temperature: -55 to 110 
