Input side is DC-coupled; output side handles up to 80 V at 50 mA per channel. Rated isolation is 3750 Vrms, which covers reinforced insulation for 300 VAC working voltage in industrial PLC, motor drive, and SMPS feedback loops. The 50% minimum CTR at 500 µA forward current ensures the LED drive stays well within a standard 5 V logic output's sink capability — no extra buffer needed. That makes this part suitable for outdoor telecom cabinets, engine-bay electronics, and downhole instrumentation where ambient heat soaks past 105°C. Switching speed is modest — 2 µs rise, 3 µs fall typical — so it fits low-frequency isolation (DC to ~100 kHz) rather than high-speed digital or CAN bus. Turn-on and turn-off times are both 3 µs typical, symmetric enough for simple PWM feedback without dead-time compensation. ## Active production — no obsolescence pressure on this BOM line Toshiba lists the TLP293-4(V4LATPE as Active. The ROHS3 compliance covers current EU and China RoHS requirements — no exemption expiry to track. Available in Tape & Reel (TR) or Cut Tape (CT) for the SO-16 package. The current transfer ratio spans 50% minimum to 600% maximum at 500 µA forward current. That 12× spread means the LED current must be set so the minimum CTR still saturates the output transistor under worst-case load. A 500 µA LED drive with 50% CTR yields 250 µA output current — enough to pull a 10 kΩ pull-up low at 2.5 V, but marginal for a 1 kΩ load. Plan the pull-up resistor around the minimum CTR, not the typical. Vce saturation is 300 mV max, which adds about 0.3 V drop in the low state — fine for 5 V logic but check the VIL threshold if the receiver runs on 3.3 V.","metaTitle":"TLP293-4(V4LATPE Toshiba Quad Transistor Optocoupler","metaDescription":"Toshiba TLP293-4(V4LATPE quad DC-input phototransistor optocoupler. 3750Vrms isolation, 50-600% CTR at 500µA, SO-16.
