Overview
The PS2805C-1-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates an AlGaAs infrared emitting diode and an NPN silicon phototransistor within a compact SSOP-4 plastic package. The device provides an isolation voltage of 2500 Vrms and supports a maximum collector-emitter voltage of 80 V. Key electrical parameters include a forward current of 30 mA, a forward voltage of 1.2 V, and a collector current of 30 mA. The current transfer ratio ranges from 100% to 400%. It operates within a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage capability of 2500 Vrms for reliable signal transmission across isolated circuits.
- Compact SSOP-4 surface mount package designed for high-density PCB applications with ambient light shielding.
- AC input response functionality suitable for direct interface with AC power sources without additional rectification.
Applications
- Programmable logic controllers
- Office automation equipment
- Measurement instruments
Procurement Notes
Verify the specific suffix F3-A against the official Renesas datasheet to confirm tape-and-reel packaging and lead-free compliance. Ensure the component matches the required channel count and pinout configuration for the target circuit design before procurement.
Selection Notes
Select this component when a single-channel isolation solution with high CTR and AC input compatibility is required. Compare the 80 V collector-emitter voltage rating against load requirements. Consider the SSOP-4 footprint constraints and thermal dissipation limits relative to adjacent components on the board.
Part Context
This part belongs to the PS2805C series of optical couplers from Renesas Electronics. The series utilizes AlGaAs LEDs for improved performance over standard GaAs devices. The PS2805C-1 variant specifically offers one channel in a four-pin package, distinguishing it from quad-channel counterparts like the PS2805C-4.
Replacement Considerations
Consult the official Renesas cross-reference documentation for verified substitutes. Generic optocouplers may not match the specific AC input response or AlGaAs LED characteristics required for equivalent performance.
