PS2561L-1-V-F3-A

Overview

The PS2561L-1-V-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80V and a maximum collector current of 50mA. The device provides high isolation with a rated insulation voltage of 5000 Vrms. Key electrical parameters include a forward current of 10mA, a typical forward voltage of 1.17V, and a saturation voltage of 300mV. Switching characteristics are defined by a rise time of 3µs and a fall time of 5µs. The component operates within a temperature range of -55°C to +100°C.

Feature Summary

• Provides galvanic isolation between input and output circuits using an LED and phototransistor configuration.
• Features a standard 4-pin surface-mount DIP package with gull-wing leads for automated assembly compatibility.
• Delivers high-voltage isolation capability suitable for separating low-voltage control logic from high-voltage loads.

Applications

• Signal isolation in industrial automation control systems
• Interface circuits connecting microcontrollers to power switching devices
• Solid-state relay driver applications requiring compact form factors

Procurement Notes

Verify the specific suffix F3-A against official Renesas documentation to confirm pinout orientation and tape-and-reel specifications. Confirm RoHS compliance status through the latest datasheet revision. Check for NRND (Not Recommended for New Designs) status if applicable to long-term supply planning. Ensure the ordering part number matches the exact package variant required for PCB layout constraints.

Selection Notes

Select this component when a single-channel isolation barrier is required with moderate speed switching capabilities. The 80V collector-emitter voltage rating suits low-to-medium voltage load driving tasks. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the 3µs/5µs switching times against system frequency requirements to ensure adequate response speeds without signal distortion or excessive delay.

Part Context

This device belongs to the PS2561L series of transistor output optocouplers from Renesas Electronics. The series is designed for general-purpose isolation applications where compact size and reliable performance are prioritized. The L-series typically denotes specific packaging and lead frame configurations optimized for surface-mount technology. This family supports various suffixes indicating different packaging quantities or material compositions.

Replacement Considerations

PS2561L-1-F3-A serves as a parameter-equivalent substitute within the same manufacturer lineup. Verify pin compatibility and electrical ratings before substitution. Other generic transistor output optocouplers may require circuit redesign due to differences in CTR, voltage ratings, or package dimensions.
