Toshiba's TLP385(BL-TPR,E is a single-channel transistor-output optocoupler in a 4-lead SOIC surface-mount package, with DC input and a 5000Vrms isolation rating. The 200-600% current transfer ratio at 5mA forward current gives a comfortable drive margin for logic-level loads up to 50mA output current and 80V output voltage.
Switching speed and temperature range
Typical rise/fall times of 2µs/3µs and turn-on/turn-off times of 3µs/3µs suit relay replacement, PLC input isolation, and motor drive feedback where microsecond-level response is acceptable. Operating range from -55°C to 110°C covers industrial and outdoor equipment without the derating needed for commercial-grade parts.
RoHS compliant, no lead-free transition risk.
Supplied in Tape & Reel (TR) or Cut Tape (CT) for the 4-lead SOIC package — the 4-pin variant of the standard SOIC body, so footprint matches the 6-pin SOIC but only four leads are active.
