Overview
The PS2815-1-V-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and supports AC input response. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a maximum collector current of 40 mA, and a forward current of 50 mA. The device provides an isolation voltage of 2500 Vrms and operates within a temperature range of -55°C to +100°C. It is housed in a 4-SSOP package.
Feature Summary
- Supports AC input signal detection with low input current requirements
- Provides high current transfer ratio for efficient signal transmission
- Offers robust electrical isolation between input and output circuits
Applications
- AC mains voltage sensing circuits
- Microcontroller interface for isolated power supplies
- Solid-state relay driver applications
Procurement Notes
Verify the specific suffix 'V' against the official datasheet to confirm pinout and packaging variations. Confirm RoHS compliance status through the manufacturer's latest documentation. Check for obsolescence notices or lifecycle changes directly from Renesas Electronics before finalizing procurement plans.
Selection Notes
Select this component when AC input detection is required alongside galvanic isolation. Ensure the 40 V collector-emitter voltage rating exceeds the load voltage. Verify that the 4-SSOP package dimensions fit the target PCB layout constraints.
Part Context
This part belongs to the PS2815 series of photo couplers designed for general-purpose isolation. The series includes variants with different channel counts and package styles. The PS2815-1-V-A specifically addresses applications needing single-channel isolation with AC input capability.
Replacement Considerations
Consult the official replacement list for direct equivalents. Cross-reference pinouts and electrical ratings carefully when considering alternative manufacturers.
