PS2501L-1-F3-H-A

Overview

The PS2501L-1-F3-H-A is a single-channel optically coupled isolator manufactured by Renesas Electronics Corporation. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN silicon phototransistor within a compact surface-mount package. The device provides high-voltage isolation of 5000Vrms between input and output circuits, ensuring signal integrity in electrically noisy environments. Key electrical characteristics include a maximum collector-emitter voltage of 80V and a peak forward current rating of 50mA. The component operates reliably across a wide temperature range from -55°C to +100°C, making it suitable for industrial applications requiring robust galvanic isolation.

Feature Summary

• Integrates a GaAs light emitting diode with an NPN silicon phototransistor for efficient optical coupling
• Provides high dielectric strength with 5000Vrms isolation voltage capability
• Designed for surface-mount assembly using a compact four-terminal SMD configuration
• Operates effectively across extended industrial temperature ranges

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission in noisy electrical environments
• Power supply feedback loops for circuit protection

Procurement Notes

Verify the specific suffix 'H' against the official Renesas datasheet to confirm lead-free compliance or specific packaging variations. Confirm that the part status remains valid for new designs, as related PS2501 series components may carry NRND status. Ensure compatibility with standard surface-mount reflow profiles during procurement planning.

Selection Notes

Select this component when a single-channel transistor-output isolator is required in a surface-mount form factor. The 5000Vrms rating supports high-voltage separation needs. Verify that the NPN phototransistor output type aligns with the destination logic interface requirements. Consider the operating temperature range if the application involves extreme environmental conditions.

Part Context

This part belongs to the PS2501 family of optocouplers, which are widely used for electrical isolation. The 'L' designation typically indicates a specific lead-free or RoHS-compliant variant, while the 'F3' and 'H' suffixes denote specific tape-and-reel packaging and manufacturing revisions. This family shares core architectural similarities with through-hole DIP versions but offers advantages in automated PCB assembly processes.

Replacement Considerations

Direct substitutes include other single-channel transistor-output optocouplers with comparable 5000Vrms isolation ratings. Verify pinout compatibility and physical footprint dimensions before substitution. Check if alternative manufacturers offer equivalent CTR specifications and switching speeds to ensure functional parity.
