Isolation voltage is 5000Vrms. ## CTR spread: 50% to 400% — design margin, not a headache Current transfer ratio is 50% minimum to 400% maximum at 5mA forward current. Vce saturation is 300mV maximum. ## Switching speed and output drive Rise time is 4µs typical and fall time is 5µs typical. Strip packaging is used for this part.","metaTitle":"PS2381-1Y-V-AX Photocoupler, 5000Vrms Isolation","metaDescription":"PS2381-1Y-V-AX single-channel transistor output photocoupler with 5000Vrms isolation, 50-400% CTR at 5mA, DC input, -40°C to 115°C.
