Overview
The PS2701-1-V-F3-H-A is a single-channel photovoltaic output optoisolator manufactured by CEL. It features a high isolation voltage of 3750Vrms and operates within a temperature range of -55°C to 100°C. The device utilizes a 4-SMD, Gull Wing package and supports DC input with transistor output. Key electrical specifications include a maximum collector-emitter voltage of 300mV, an output voltage rating of 40V, and a channel current capacity of 80mA. The typical rise and fall times are 3µs and 5µs respectively, with a minimum current transfer ratio of 50% at 5mA input.
Feature Summary
- High isolation voltage capability for safe signal transmission between circuits
- Photovoltaic output design providing galvanic isolation
- Compact surface-mount packaging suitable for automated assembly
Applications
- Industrial control systems requiring electrical isolation
- Medical equipment safety circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix variants carefully as they may indicate different packaging or testing conditions. Confirm availability status as this part number has been marked as discontinued by major distributors. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.
Selection Notes
Consider the 3750Vrms isolation rating when designing for high-voltage separation needs. Evaluate the 80mA output current capability against load requirements. Check the operating temperature range suitability for the intended environment. Verify package dimensions against board space constraints.
Part Context
This component belongs to the NEPOC series of optoisolators from CEL. It represents a specialized solution for applications demanding robust electrical isolation in a compact form factor. The photovoltaic output type distinguishes it from standard transistor or logic-output isolators.
Replacement Considerations
Check for direct pin-compatible substitutes from other manufacturers offering similar isolation voltages and package types. Verify that any replacement maintains the same current transfer ratio and switching speed characteristics.
