Overview
The PS2761B-1-V-F3-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor in a 4-pin SOP package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and an isolation voltage of 3750 Vrms. The device operates with a forward current of 5 mA and features a typical rise time of 4 µs and fall time of 5 µs. It supports a wide operating temperature range from -55°C to +110°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Integrates a GaAs LED with an NPN phototransistor for signal transmission
- Designed for compact surface-mount installation in space-constrained applications
Applications
- Industrial automation control systems
- Automotive electronic modules
- Power supply feedback loops
Procurement Notes
Verify the specific suffix K-A against official Renesas documentation to confirm tape-and-reel packaging and lead-free status. Confirm RoHS compliance details directly from the manufacturer datasheet. Check regional distribution restrictions as availability may vary by location. Ensure the component matches the required SOP-4 footprint for PCB integration.
Selection Notes
Select this component when high isolation voltage and fast switching speeds are required in a small form factor. Compare the 3750 Vrms isolation rating against system safety requirements. Evaluate the 50 mA collector current capacity against load demands. Consider the -55°C to +110°C temperature range for environmental suitability.
Part Context
This part belongs to the PS2761B series of single-channel optocouplers. The series is characterized by its use of GaAs LEDs and NPN phototransistors.
