Productos<\/h2>\n

TLP184 from Toshiba is a phototransistor photocoupler with 3750Vrms isolation and high CTR (50-300%) in compact MFSOP-6. 8mm creepage meets IEC safety. GaAlAs LED and silicon phototransistor for fast response.<\/p>\n

Principio de funcionamiento<\/h2>\n

GaAlAs infrared LED emits light detected by phototransistor. LED current (IF) causes proportional collector current (IC = IF x CTR). Optical coupling provides electrical isolation with no electrical connection.<\/p>\n
