PS2801C-1-M-A

Overview

The CEL PS2801C-1-M-A is a single-channel transistor output optocoupler housed in a plastic SSOP package. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN silicon phototransistor. The device provides high isolation voltage of 2500 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a forward current of 5 mA, and a typical forward voltage of 1.2 V. The Current Transfer Ratio ranges from 100% to 400% at 5 mA input. 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 SSOP package design suitable for space-constrained printed circuit boards
• Integration of GaAs LED and NPN phototransistor for reliable optical coupling

Applications

• Industrial control systems requiring galvanic isolation
• Measurement equipment needing signal separation
• Power supply circuits for feedback loop isolation

Procurement Notes

Verify the specific suffix 'M-A' against the manufacturer's latest datasheet to confirm pinout and packaging variations. Ensure compliance with RoHS directives if required by your application standards. Cross-reference the part number with official Renesas or CEL documentation to avoid counterfeit components. Check for any end-of-life notices or recommended alternative parts before finalizing procurement plans.

Selection Notes

Select this component when a single channel of isolation is sufficient for the circuit design. Consider the 80 V collector-emitter voltage rating to ensure it meets the load requirements. Verify that the 100% to 400% CTR range aligns with the switching speed and drive current capabilities of the interfacing logic. The SSOP-4 package requires appropriate footprint design for surface mount assembly.
