PS2805C-1-V-A

Overview

The PS2805C-1-V-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates an AlGaAs light-emitting diode and an NPN silicon phototransistor within a compact SSOP-4 surface-mount package. The device provides electrical isolation with a rated insulation voltage of 2500 Vrms. Key electrical parameters include a collector-emitter voltage (VCEO) of 80 V, a maximum forward current (If) of 5 mA, and a typical forward voltage (Vf) of 1.2 V. The unit supports AC input response and features a current transfer ratio ranging from 50% to 400%. Operating temperatures span from -55°C to +100°C.

• Hybrid integrated circuits

Procurement Notes

Verify the specific suffix 'V' against official Renesas documentation to confirm compliance with regional safety standards such as VDE or BSI, as these certifications are often option-dependent. Confirm the component lifecycle status, as similar PS2805C variants may carry Not Recommended for New Designations. Ensure the selected package matches the required PCB footprint and that the manufacturer's datasheet explicitly lists this exact part number before finalizing procurement plans.

Selection Notes

Select this component when a single-channel isolation solution with high collector-emitter voltage is required in a small form factor. The AC input response makes it suitable for direct coupling with AC signals without additional conditioning. Consider the thermal dissipation limits of the SSOP-4 package under continuous operation. Verify that the required current transfer ratio falls within the specified range for the target application load conditions.

Part Context

This component belongs to the PS2805C series of optical coupler isolators produced by Renesas Electronics. The series utilizes AlGaAs LEDs paired with NPN phototransistors to achieve reliable signal transmission across isolated barriers. The PS2805C-1 variant specifically denotes a single-channel configuration housed in a 4-pin SSOP package, distinguishing it from multi-channel counterparts like the PS2805C-4.
