Overview
The PS2501-1XGRSMT&R is a single-channel optocoupler manufactured by Isocom Components. It features an infrared LED input coupled to an NPN phototransistor output, housed in a surface-mount package. The device provides high isolation voltage of 5000Vrms between input and output circuits. Key electrical parameters include a minimum current transfer ratio of 130% and a maximum forward voltage of 1.4V. It operates within a temperature range of -55°C to 100°C and supports a maximum forward current of 80mA.
Feature Summary
- Provides galvanic isolation for signal transmission between separate circuits
- Integrates an infrared LED with an NPN phototransistor output stage
- Designed for surface-mount assembly to facilitate automated manufacturing processes
Applications
- Industrial control systems requiring circuit isolation
- Power supply feedback loops for voltage regulation
- Communication interfaces needing noise immunity
Procurement Notes
Verify the specific suffix 'GRSMT&R' against official manufacturer documentation to confirm tape-and-reel packaging configuration and lead finish specifications. Ensure compliance with RoHS directives and check for any design-life notices or obsolescence warnings prior to procurement. Cross-reference pinout diagrams with target PCB layout requirements.
Selection Notes
Select this component when high isolation voltage and moderate speed are required for DC signal switching applications. Consider the NPN open-collector output structure for compatibility with standard logic levels. Evaluate thermal management needs given the operating temperature range and power dissipation limits during continuous operation.
Part Context
This part belongs to the PS2501 series of single-channel optocouplers from Isocom Components. The series is designed as a replacement for industry-standard devices, offering comparable performance characteristics. It utilizes standard semiconductor fabrication processes to ensure reliability and consistency across production batches.
Replacement Considerations
Public confirmed substitute part numbers: RV1S2281A (DC Input/Single Transistor Output), PS2561DL-1 (Same Package, 110°C Operating Ambient Temperature). Verify pinout compatibility and electrical parameter margins before substitution.
