The TLP184 from Toshiba is a 1-channel photocoupler with 50-300% CTR, 3750Vrms isolation, and 10Mbps data rate in SO6L for digital signal isolation.
The TLP184 is a phototransistor optocoupler from Toshiba in SO6L (SOP-6 with base pin) package with 3750Vrms isolation. The input LED emits infrared light at 940nm when forward-biased (IF = 5-50mA typical). The phototransistor on the output side detects this light: photons generate electron-hole pairs in the base-collector region, creating a photocurrent that acts as base current. The transistor amplifies this by its hFE (typically 100-500), producing a collector current IC = CTR x IF, where CTR (Current Transfer Ratio) ranges from 50% to 300% depending on the bin. The base pin (pin 6) is a unique feature of the TLP184: it allows connecting an external resistor between base and emitter to control switching speed vs CTR. A base-emitter resistor (e.g., 1M-ohm) speeds up turn-off by providing a discharge path for stored base charge, reducing fall time from 50us to 5us at the cost of reduced CTR. Without the base resistor, the stored charge in the base causes slow turn-off (current tail). The 3750Vrms isolation rating meets IEC 60747-5-5 safety requirements for reinforced insulation at mains voltages up to 300Vrms. The SOP-6 footprint (5.2×7.4mm) is wider than SOP-4, providing increased creepage (7mm) and clearance (7mm). Applications include AC-DC power supply feedback, relay driving, and signal isolation.
