Overview
The PS2801A-1-V-F3-M-A is a single-channel transistor output optocoupler manufactured by CEL (California Eastern Labs), part of the Renesas PS2801 series. It features an NPN phototransistor output and utilizes SSOP-4 surface-mount packaging with a 1.27 mm pin pitch. Key electrical specifications include a high isolation voltage of 2500 Vrms, a maximum collector-emitter voltage of 70 V, and a maximum collector current of 30 mA. The device operates within a temperature range of -55°C to +100°C, with a typical forward voltage of 1.4 V at 30 mA input current.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes a compact SSOP-4 package for space-constrained applications
- Features NPN phototransistor output for digital signal transmission
Applications
- Industrial control systems requiring circuit isolation
- Microcontroller interface circuits
- Power supply feedback loops
Procurement Notes
Verify the manufacturer designation carefully, as this component is associated with both CEL and Renesas Electronics due to corporate acquisitions. Confirm the specific suffix 'M-A' against official datasheets to ensure correct packaging and tape-and-reel specifications. Check RoHS compliance status directly from the supplier documentation prior to ordering.
Selection Notes
Select this component when a single-channel isolation solution with moderate speed and high voltage tolerance is required. Compare the 30 mA collector current limit against load requirements. Ensure the SSOP-4 footprint matches the PCB design constraints. Verify that the 2500 Vrms isolation rating meets the safety standards of the target application environment.
Part Context
This part belongs to the PS2801 family of high-isolation photocouplers. The series is characterized by small form factors and robust insulation capabilities. Variants within the family differ in channel count and specific electrical ratings, but generally share the same core technology and packaging styles designed for reliable signal transfer across isolated boundaries.
Replacement Considerations
Cross-reference with PS2801A-1-F3 or PS2801A-1-A for functional equivalents. Verify pin compatibility and electrical parameter overlaps before substitution. Note that Renesas may have updated naming conventions for these components.
