Overview
The PS2505-1XSMT&R is a surface-mount optocoupler from Isocom Components, featuring one channel with an NPN silicon phototransistor output. It utilizes infrared LEDs connected in inverse parallel for AC or polarity-insensitive input. The device offers high isolation voltage of 5.3 kVrms and 7.5 kVpk. Key electrical parameters include a minimum current transfer ratio of 50% and a maximum forward voltage of 1.65V. Typical switching times are 4µs rise and 3µs fall. It operates within a temperature range of -30°C to 100°C.
Feature Summary
- AC or polarity insensitive input configuration using inverse parallel LEDs
- High isolation voltage capability for safe signal transmission between different potentials
- Space-efficient surface mount packaging design
Applications
- Computer terminals
- Industrial systems controllers
- Telephone sets and exchanges
- Signal transmission between systems of different potentials and impedances
Procurement Notes
Verify the specific suffix 'SMT&R' confirms tape-and-reel packaging availability when ordering. Confirm that the 'X' designation aligns with the required lead spread or package variant specifications for your PCB layout. Ensure the component meets all relevant safety certifications such as UL recognition if required for your final product compliance.
Selection Notes
Select this component for applications requiring AC input response without additional rectification circuitry. The surface mount format is suitable for automated assembly processes. Consider the 5.3 kVrms isolation rating for robust noise immunity in industrial environments. Verify that the phototransistor output current capabilities match the load requirements of the receiving circuit.
Part Context
This part belongs to the PS2505 series of high-density optically coupled isolators manufactured by Isocom Components. The series is designed for space-constrained applications while maintaining high reliability. It serves as a replacement for legacy through-hole variants, offering similar electrical performance in a compact surface-mount footprint suitable for modern electronics manufacturing.
Replacement Considerations
Direct substitutes include other PS2505 series variants such as PS2505-1SM or PS2505-1SMT&R from compatible manufacturers. Cross-reference pinouts and isolation voltages to ensure compatibility. Verify that alternative parts support AC input operation and meet the same thermal and electrical specifications.
