PS2805C-1-V-F3-A

Overview

The PS2805C-1-V-F3-A is a single-channel transistor output optocoupler from Renesas Electronics, housed in a compact SSOP-4 surface-mount package. It integrates an aluminum gallium arsenide (AlGaAs) LED with an NPN silicon phototransistor for electrical isolation. The device supports AC input response and features a high collector-to-emitter voltage of 80 V. Key electrical parameters include a minimum current transfer ratio of 50%, a maximum forward current of 30 mA, and a typical rise/fall time of 5 μs/7 μs. It offers an insulation voltage of 2500 Vrms and operates within a temperature range of -55°C to +100°C.

Procurement Notes

Verify the specific suffix 'V' against official Renesas documentation to confirm its exact meaning regarding lead-free status or tape/reel specifications. Ensure compatibility with standard SMD reflow soldering profiles. Confirm that the component meets required safety certifications such as UL1577 or CSA standards for the intended application environment. Check for any obsolescence notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when a single channel of high-voltage isolation is required in a small footprint. It is appropriate for designs needing AC input response and moderate switching speeds. Compare the 80 V collector-emitter voltage and 30 mA current limits against load requirements. Consider the thermal dissipation capabilities and operating temperature range relative to the system's environmental conditions.

Part Context

This part belongs to the PS2805C series of optical couplers, which are designed for general-purpose isolation tasks. The series utilizes AlGaAs LEDs and NPN phototransistors to provide reliable signal transmission across isolated barriers. The PS2805C-1 variant specifically provides one isolated channel, distinguishing it from quad-channel versions like the PS2805C-4. The family is known for balancing performance with cost-effectiveness in industrial and consumer electronics.

Replacement Considerations
