Overview
The PS2761B-1Y-V-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output housed in a compact SOP-4 surface-mount package. The device provides high isolation with a rated insulation voltage of 3750 Vrms, ensuring reliable signal transmission across isolated circuits. Key electrical parameters include a maximum collector-emitter voltage of 70 V and a maximum collector current of 50 mA. The input side operates with a forward current of 5 mA and a forward voltage of 1.1 V. The component supports a wide operating temperature range from -55°C to +110°C and exhibits switching times of 5 µs for both rise and fall durations.
Feature Summary
- Provides galvanic isolation between input control signals and output loads via optical coupling.
- Features a compact SOP-4 surface-mount package designed for automated assembly processes.
- Delivers high dielectric strength with a 3750 Vrms insulation rating for safety-critical applications.
Applications
- Industrial automation control systems requiring signal isolation
- Power supply feedback loops for voltage regulation
- Microcontroller interface circuits for noise immunity
Procurement Notes
Verify the specific suffix 'V' against the official Renesas datasheet to confirm if it denotes a specific tape-and-reel packaging variant or a distinct electrical parameter set compared to standard versions. Ensure the requested part number matches the exact ordering code in the manufacturer's current catalog to avoid receiving non-conforming inventory or obsolete stock.
Selection Notes
Select this component when a single-channel isolation solution with moderate speed (5 µs) and high voltage tolerance is required. The SOP-4 package is suitable for space-constrained PCB layouts. Compare the 70 V collector-emitter voltage limit against the load requirements to ensure adequate headroom. Consider the 5 mA forward current requirement for drive circuit design compatibility.
Part Context
This device belongs to the PS2761B series of transistor output optocouplers. The series is characterized by its small footprint and robust isolation capabilities, making it a common choice for general-purpose digital signal isolation in consumer and industrial electronics where board space is limited but safety standards must be met.
Replacement Considerations
Direct substitutes may include other PS2761B variants with compatible pinouts and electrical ratings. Verify that any replacement maintains the same SOP-4 package dimensions and 3750 Vrms isolation rating to ensure mechanical and electrical compatibility without redesigning the host circuit.
