Overview
The PS2501-1GR is a single-channel optocoupler from the PS2501 series, manufactured by Isocom Components. It features an infrared LED input and an NPN phototransistor output housed in a surface-mount PDIP package with 4 pins. The device provides a high isolation voltage of 5300Vrms, ensuring reliable signal transmission between isolated circuits. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 4μs, and a typical fall time of 3μs. It operates within a temperature range of -30°C to 100°C and supports a maximum input current of 50mA.
Feature Summary
- Provides galvanic isolation between input and output circuits using infrared light transmission.
- Features an NPN phototransistor output for digital signal switching applications.
- Designed for surface-mount assembly to facilitate automated PCB manufacturing.
Applications
- High-voltage isolation interfaces
- Digital signal transmission across isolated grounds
- Industrial control system inputs
Procurement Notes
Verify the specific suffix 'GR' against official manufacturer documentation to confirm surface-mount packaging and tape-and-reel availability. Ensure the selected variant matches the required isolation voltage rating of 5300Vrms for your circuit design. Cross-reference the part number with authorized distributors to confirm current production status and lead times.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation. Compare the 5300Vrms isolation rating against system safety requirements. Consider the 4μs rise time for signal integrity in high-speed digital applications. Verify that the NPN output configuration aligns with the load requirements of the receiving circuit.
Part Context
The PS2501 series represents a family of general-purpose optocouplers designed for robust performance in industrial and commercial applications. This specific model utilizes a standard DIP footprint adapted for surface mount, offering compatibility with existing through-hole designs while enabling modern SMD assembly processes. The series is known for meeting international safety standards.
Replacement Considerations
Direct replacements may include other PS2501 variants such as PS2501-1 or PS2501-1X, provided the package type and electrical characteristics match. Verify pinout compatibility and isolation voltage ratings before substitution. Consult official datasheets for equivalent parts from other manufacturers if Isocom components are unavailable.
