The device provides an insulation voltage of 3750 Vrms and exhibits a current transfer ratio ranging from 50% to 300%. The rise time is specified as 3 µs.

Feature Summary

• Provides electrical isolation between input and output circuits using infrared LED and phototransistor technology.
• Features a compact SOP-4 surface mount package for automated assembly and space-constrained designs.
• Includes internal shielding to block external light interference and ensure signal integrity.

Applications

• Digital logic signal transmission and level shifting
• Power supply control and switching circuits
• Electrical isolation between systems and impedance transformation

Procurement Notes

Verify the component status before procurement, as the PS2701-1-A is listed as NRND (Not Recommended for New Designs). Confirm availability through authorized distributors or stockists, as standard manufacturing may be discontinued. Ensure that the specific pinout and electrical characteristics match the design requirements, as replacement components may require circuit adjustments.

Selection Notes

Select this component for applications requiring moderate speed and high isolation voltage in a small footprint. The 40 V collector-emitter voltage and 80 mA collector current suit low-to-medium power switching tasks. Consider the NRND status when designing new products; alternative models within the PS2701A series may offer better long-term supply stability while maintaining similar functional specifications.
