PS2815-4-V-A

Overview

The PS2815-4-V-A is a four-channel phototransistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output configuration with a high current transfer ratio (CTR) suitable for AC input applications. The device provides electrical isolation with a rated insulation voltage of 2500 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a maximum collector current of 40 mA, and a forward voltage of 1.4 V at a forward current of 50 mA. Power dissipation is rated at 120 mW, and the unit operates within a temperature range of -55°C to +100°C.

Feature Summary

• Four independent channels integrated into a single package for multi-signal isolation
• High current transfer ratio optimized for direct AC line sensing applications
• NPN phototransistor output structure providing standard switching capabilities

Applications

• AC power line monitoring and detection circuits
• Multi-channel signal isolation in industrial control systems
• Solid-state relay driver interfaces requiring high CTR

Procurement Notes

Verify component availability status prior to design finalization, as supply constraints may apply. Confirm that the specific suffix denotes the correct packaging format required for assembly processes. Ensure compliance with RoHS directives and check for any regional distribution restrictions or end-of-life notifications associated with this specific part number variant before committing to production volumes.

Selection Notes

Select this component when multiple isolated channels are required for AC input monitoring within a compact footprint. The high CTR specification makes it suitable for applications demanding reliable switching from low drive currents. Consider the 40 V collector voltage limit and 120 mW power dissipation rating against thermal management requirements in dense PCB layouts compared to lower channel count alternatives.

Part Context

This part belongs to the PS2815 series of high CTR optocouplers designed specifically for AC input detection. It shares the family's core isolation architecture but differs in channel count and specific electrical characteristics compared to single-channel variants like the PS2811 or other multi-channel models such as the PS2801. The series targets cost-effective isolation solutions for consumer and industrial AC mains interfacing.
