PS2801C-1-V-F3-L-A

Overview

The PS2801C-1-V-F3-L-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN silicon phototransistor within a compact 4-pin SSOP package with a 1.27 mm pin pitch. The device provides high isolation voltage of 2500 Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum forward current of 30 mA, and a typical current transfer ratio of 150% at 5 mA. It operates within a temperature range of -55°C to +100°C.

Feature Summary

• High isolation voltage capability for safe signal transmission across potential barriers
• Compact and thin plastic SSOP package design suitable for space-constrained applications
• Integration of GaAs LED and NPN phototransistor for efficient optical coupling

Applications

• Industrial control systems requiring galvanic isolation
• Measurement and testing equipment signal interfaces
• Communication devices needing noise immunity

Procurement Notes

Verify the specific suffix 'V' and 'L' against official Renesas documentation to confirm lead-free status and RoHS compliance details. Confirm availability as this component may be subject to limited supply or end-of-life status depending on the current production cycle. Ensure the ordering part number matches the exact package and tape/reel configuration required for your assembly process.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed and high voltage tolerance is required. The 4-pin SSOP package is ideal for surface-mount applications where board space is limited. Consider the 2500 Vrms isolation rating for safety-critical interfaces. Verify that the NPN phototransistor output configuration aligns with the downstream circuit requirements.

Part Context

This part belongs to the PS2801 series of optocouplers from Renesas, which are designed for general-purpose isolation tasks. The series includes various channel counts and package options. The PS2801C variant specifically denotes the single-channel configuration with defined electrical characteristics distinct from multi-channel versions like the PS2801-4.

Replacement Considerations

Check for direct substitutes such as PS2801C-1-F3-A or PS2801C-1-V-F3-A if the 'L' suffix indicates a specific packaging or environmental variation. Ensure any replacement maintains the same 4-pin SSOP footprint and electrical ratings.
