Overview
The PS2502-1XSMT&R is a surface-mount optocoupler manufactured by Isocom Components. It features a single channel configuration with a Darlington transistor output device. The component utilizes a DIP-style package with six pins for circuit integration. Key electrical specifications include a maximum forward voltage of 1.6V and a maximum input current rating of 50mA. The unit provides an isolation voltage of 5300Vrms to ensure signal integrity between circuits. Performance metrics indicate a typical rise time of 4µs and a typical fall time of 3µs. The minimum current transfer ratio is specified at 80%, while the maximum reaches 200%.
Feature Summary
- Provides high-gain signal transmission via a Darlington transistor output stage
- Ensures robust electrical isolation between input and output circuits
- Designed for compact surface-mount assembly on printed circuit boards
Applications
- Industrial control systems requiring galvanic isolation
- Power supply units for feedback loop monitoring
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix 'SMT&R' confirms the surface-mount tape-and-reel packaging format required for automated assembly lines. Confirm that the 'X' designation aligns with the intended Darlington output characteristics and pinout compatibility for your specific PCB layout design requirements.
Selection Notes
Select this component when high current gain is necessary to drive loads directly without additional amplification stages. The Darlington output structure offers superior sensitivity compared to standard phototransistor variants, making it suitable for low-input-current applications where maximum isolation performance is critical.
Part Context
This part belongs to the PS2502 series of optocouplers produced by Isocom Components. The series is characterized by its use of Darlington output configurations to achieve high current transfer ratios. These devices are engineered to replace legacy components in industrial and commercial equipment designs requiring reliable optical isolation.
Replacement Considerations
Cross-reference with other PS2502-series variants or equivalent Darlington output optocouplers from different manufacturers. Ensure pin compatibility and isolation voltage ratings match the original design specifications before substitution.
