Overview
The PS2801C-1-V-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs light emitting diode and an NPN silicon phototransistor within a compact 4-pin SSOP package. The device provides high isolation voltage of 2500 Vrms, ensuring robust electrical separation between input and output circuits. Key electrical parameters include a collector-emitter breakdown voltage (VCEO) of 80 V, a typical rise time of 5 µs, and a fall time of 7 µs. The current transfer ratio ranges from 50% to 400% at a forward current of 5 mA. It operates within a temperature range of -55°C to +100°C and features a maximum DC forward current of 30 mA.
Feature Summary
- High isolation voltage capability for safe signal transmission across potential barriers
- Compact plastic SSOP package designed for high-density surface mount applications
- Integrated shield effect to minimize interference from ambient light sources
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in measurement and testing equipment
- Power supply feedback loops for circuit protection
Procurement Notes
Verify the specific suffix 'V-A' against the official Renesas datasheet to confirm pinout compatibility and tape/reel specifications. Confirm RoHS compliance status as indicated in the product documentation. Check for any recent lifecycle changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a single-channel isolation solution with moderate switching speed is required. Ensure the application voltage does not exceed the 80 V collector-emitter rating. Consider the 4-pin SSOP footprint constraints during PCB layout design. Verify that the required current transfer ratio falls within the specified 50% to 400% range for the given operating conditions.
Part Context
This part belongs to the PS2801C series of high isolation voltage SSOP photocouplers. The series includes variants such as PS2801C-1 and PS2801C-4, differing primarily in channel count. The PS2801C-1-V-A specifically denotes the single-channel version with specific packaging and compliance attributes defined by the manufacturer's ordering nomenclature.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult the official Renesas cross-reference guide or contact technical support for verified alternatives if this component is unavailable.
