3750Vrms isolation in a compact 6-SOP package
The Toshiba TLP183(GRL,E is a single-channel transistor-output optocoupler with 3750Vrms isolation in a 6-SOP package (4.40mm width). The DC input and transistor output provide a CTR range of 100% to 200% at 5mA forward current.
The 100% to 200% CTR at 5mA means the output transistor can sink at least as much current as the LED drives, with headroom for degradation over the product life. At 5mA input, the output can saturate to 300mV max (Vce(sat)), keeping logic-level interfaces clean. Rise and fall times are 2µs and 3µs typical, with turn-on/off times of 3µs each — fast enough for 100 kHz switching supplies or low-speed serial isolation, but not for high-speed data links. The 50mA output current rating and 80V output voltage allow direct drive of small relays, solid-state relays, or PLC input modules without a buffer transistor.
The wide range also covers military/aerospace ground-support equipment, though the part lacks formal MIL-screening.
