PS2815-4

Overview

The PS2815-4 is a four-channel transistor output optocoupler manufactured by CEL. It features an isolation voltage of 2500 Vrms and utilizes NPN phototransistors for signal transmission. The device supports AC input response and offers a high current transfer ratio, typically 200% at ±1 mA forward current. It operates within a temperature range of -55°C to +100°C and is housed in a plastic SSOP package.

Feature Summary

• Four-channel configuration for multi-signal isolation
• AC input response capability
• High current transfer ratio performance
• Robust electrical isolation

Applications

• Industrial control systems requiring multi-channel isolation
• AC power monitoring circuits
• Signal interface between microcontrollers and high-voltage loads

Procurement Notes

Verify the specific suffix (e.g., -A, -L-A) as it denotes package or variant differences. Confirm lifecycle status, as this component may be obsolete or limited supply. Ensure the manufacturer designation matches requirements, as production has shifted between Renesas and CEL. Check RoHS compliance details for regulatory adherence.

Selection Notes

Select based on the requirement for four isolated channels in a compact form factor. Consider the high CTR for efficient drive requirements with low input current. Verify the operating temperature range suitability for the intended environment. Ensure the 2500 Vrms isolation rating meets safety standards for the application voltage levels.

Part Context

This component belongs to the PS2815 series of optocouplers designed for high-performance isolation. The series includes single-channel variants like the PS2815-1. These devices are engineered for applications demanding reliable signal transfer across potential barriers with minimal input current consumption.

Replacement Considerations
