Overview
The PS2801C-4-F3-A is a quad-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and utilizes a GaAs infrared LED for input isolation. The device is housed in a compact SSOP-16 surface-mount package with a 1.27 mm pin pitch, designed for high-density applications. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum forward current of 50 mA, and a typical rise time of 3 µs. It provides an isolation voltage of 2500 Vrms and operates within a temperature range of -55°C to +100°C.
Feature Summary
- Provides four independent channels for signal isolation within a single compact package.
- Features high isolation voltage capability suitable for safety-critical circuit separation.
- Includes environmental light shielding to ensure stable operation under varying lighting conditions.
Applications
- Programmable logic controllers
- Measurement instruments
- Power supply units
Procurement Notes
Verify the specific suffix 'F3' against the manufacturer's latest documentation to confirm tape and reel packaging specifications. Ensure that the component designation matches the exact datasheet revision required for your design. Cross-reference the part number with official Renesas databases to confirm availability status and any potential lifecycle changes before finalizing procurement plans.
Selection Notes
Select this component when multiple isolated channels are required in a space-constrained environment. The quad configuration reduces board area compared to discrete solutions. Consider the 80 V collector-emitter voltage rating for low-voltage switching applications. Verify that the 3 µs rise time meets the speed requirements of the target interface signals.
Part Context
This part belongs to the PS2801 series of transistor output optocouplers from Renesas. The series is characterized by its small SSOP footprint and high isolation performance. The PS2801C-4 variant specifically offers four channels, distinguishing it from single or dual-channel counterparts in the same family. It is designed for general-purpose industrial and commercial isolation tasks.
Replacement Considerations
Consult the official Renesas replacement guide for verified substitute part numbers. Generic equivalents may not match the specific isolation voltage or channel count requirements. Do not assume cross-compatibility with other manufacturers without verifying pinout and electrical parameter alignment.
