PS8101-V-A

Overview

The CEL PS8101-V-A is a single-channel optoisolator featuring a GaAlAs LED input and a phototransistor output. It provides 3750 Vrms isolation voltage and supports a maximum supply voltage of 35V. The device operates within a temperature range of -55°C to 100°C, with a typical turn-on time of 500ns and turn-off time of 600ns. It delivers an output current of 8mA per channel and is housed in a compact SO-5 plastic package.

Feature Summary

• High common mode transient immunity for noise reduction
• Compact SO-5 small outline package design
• High isolation voltage rating for safety compliance

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops
• Microcontroller interface circuits

Procurement Notes

Verify the specific suffix (e.g., -F3, -F4) for tape-and-reel quantities if automated assembly is required. Confirm lead-free status and RoHS compliance against current regulatory requirements. Check manufacturer documentation for updated safety approvals such as UL or CSA before final integration.

Selection Notes

Select this component when high-speed response and robust isolation are critical. Ensure the input current does not exceed 25mA and the output voltage remains within 35V limits. Consider the operating temperature range for extreme environmental conditions.

Part Context

This part belongs to the NEPOC series of linear IC output optocouplers originally developed by NEC. It integrates a PIN photodiode and amplifier on one chip for high-speed performance. The product line emphasizes high density applications through its small package footprint.

Replacement Considerations

The PS8101-V-A is listed as obsolete. Substitutes include PS8101-V-F3-K-AX and PS8101-V-F4-AX-K from CEL or Renesas. Verify pin compatibility and electrical parameters before replacement.
