PS2701A-1-A

Overview

The PS2701A-1-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates with a maximum collector-emitter voltage of 70 V and a collector current of 30 mA. The device provides high isolation capability with an insulation voltage of 3750 Vrms. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.4 V, and a power dissipation of 80 mW. The current transfer ratio ranges from 50% to 300%. It supports a wide operating temperature range from -55°C to +100°C and utilizes a SOP-4 surface mount package.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using optical transmission.
• Integrates an NPN phototransistor for reliable signal switching in low-power applications.
• Features a compact SOP-4 surface-mount package designed for automated assembly processes.

Applications

• Industrial control systems requiring circuit isolation
• AC input detection circuits
• General-purpose signal isolation interfaces

Procurement Notes

Verify the specific suffix 'A' against official Renesas documentation to confirm pinout and electrical tolerances. Confirm RoHS compliance status through the manufacturer's datasheet. Check the product lifecycle status as components may be marked as NRND or obsolete. Ensure the SOP-4 package variant matches the design footprint requirements before procurement.

Selection Notes

Select this component when a single channel of isolation with moderate speed and high voltage tolerance is required. Compare the 70 V collector-emitter rating against system voltage peaks. Evaluate the 50 mA forward current requirement against available drive capabilities. Consider the SOP-4 package size constraints relative to other optocoupler families like PS2501 or PS2801.

Part Context

This part belongs to the PS2701A series of transistor output optocouplers. It shares architectural similarities with other Renesas optocouplers but differs in package type and specific electrical ratings. The series is designed for general-purpose isolation tasks in industrial and consumer electronics.

Replacement Considerations

PS2701A-1-F3-M-A offers similar isolation but different packaging and current ratings. PS2701A-1Y-V-F3-A provides comparable performance with specific tape-and-reel options. Verify pin compatibility and electrical limits before substituting.
