Overview
The PS2501-4GR is a four-channel optocoupler from the PS2501 series manufactured by Isocom Components. It features a DIP-16 package with through-hole mounting and AC input configuration. Key electrical parameters include a maximum forward voltage of 1.4V, typical rise time of 4μs, and typical fall time of 3μs. The device supports a maximum input current of 50mA and offers an isolation voltage of 5300Vrms. Operating temperatures range from -30°C to 100°C, with a minimum current transfer ratio of 80% and a maximum of 6%. It holds UL certification.
Feature Summary
- Four-channel optical coupling architecture for multi-circuit isolation
- AC input compatibility for direct signal interfacing
- High isolation voltage rating for safety compliance
- Through-hole DIP-16 packaging for standard board integration
Applications
- Industrial control systems
- Power supply protection circuits
- Smart metering devices
- Gas detection and monitoring equipment
Procurement Notes
Verify the specific suffix 'GR' against official manufacturer documentation to confirm pinout and material specifications. Ensure the selected variant matches the required AC input characteristics and DIP-16 form factor. Cross-reference datasheet values for isolation voltage and operating temperature ranges before finalizing procurement orders.
Selection Notes
Select this component when multi-channel isolation is required within a single package footprint. The AC input type distinguishes it from DC-input variants in the same series. Verify that the 5300Vrms isolation rating meets system safety standards. Confirm that the DIP-16 package dimensions align with the target PCB layout constraints.
Part Context
This part belongs to the PS2501 series of high-performance infrared optoelectronic devices. Isocom Components manufactures these components as alternatives to common commercial optocouplers. The series includes various channel counts and package types, with this specific model providing four channels in a 16-pin DIP configuration.
Replacement Considerations
PS2501-4X is a documented equivalent part number offering identical four-channel functionality and DIP-16 packaging. Verify pin compatibility and electrical parameter alignment before substitution.
