It accepts DC input and delivers a transistor output with a current transfer ratio (CTR) of 100% to 300% at a forward current of 5mA. ## CTR range and drive margin With a CTR spanning 100% to 300% at 5mA forward current, this optocoupler provides a wide operating margin for the LED drive circuit. A minimum CTR of 100% means the output transistor can sink at least as much current as the LED forward current, which simplifies gain budgeting in logic-level isolation interfaces. The 300% maximum gives headroom for LED aging or temperature variation without saturating the output stage. ## Switching speed and output ratings Rise and fall times are 4µs and 5µs typical, placing this part in the general-purpose speed class — adequate for 10-100 kHz switching in relay drivers, AC mains zero-crossing detectors, and status feedback loops. The output transistor can handle up to 80V and 50mA continuous, with a Vce saturation maximum of 300mV at rated current. The 60mA absolute maximum forward current on the input side sets the LED drive limit. ## Temperature range and environment Rated for operation from -40°C to 115°C, the PS2381-1Y-V-L-AX covers industrial temperature requirements and can be used in outdoor telecom cabinets, factory-floor sensors, and engine-bay electronics where ambient temperatures stay below 115°C. The 5000Vrms isolation rating supports reinforced insulation for safety-critical applications per IEC 60950-1 and similar standards. ## Lifecycle and compliance For dual-sourcing or drop-in replacement evaluation, the NEPOC family includes several 4-pin gull-wing optocouplers with similar pinouts — confirm CTR and isolation voltage against your BOM requirements.","metaTitle":"PS2381-1Y-V-L-AX NEPOC Optocoupler, 5000Vrms Isolation","metaDescription":"PS2381-1Y-V-L-AX NEPOC optocoupler: 5000Vrms isolation, transistor output, 100%-300% CTR @5mA, -40°C to 115°C, 4-LSOP gull wing.
