Overview
The PS2505-1XSM is a single-channel optocoupler manufactured by Isocom Components, featuring an infrared LED input and a Darlington transistor output. It utilizes a surface-mount SOP-8 package for compact integration. The device provides high isolation voltage of 5300Vrms between input and output circuits. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 60μs, and a typical fall time of 53μs. It operates within a temperature range of -30°C to +100°C and supports a maximum input current of 50mA.
Feature Summary
- High isolation voltage capability for safe circuit separation
- Darlington output configuration for enhanced current transfer ratio
- Surface-mount packaging for automated assembly efficiency
Applications
- Logic-to-logic isolation in noisy environments
- Line receiver applications
- Programmable current level sensors
- Motor and servo machine digital control interfaces
Procurement Notes
Verify the specific suffix 'SM' confirms the surface-mount SOP-8 package variant rather than through-hole DIP. Confirm that the Darlington output type matches the target circuit requirements for switching speed and saturation voltage. Ensure compliance with RoHS directives if required by the end application standards.
Selection Notes
Select this component when high current gain from the Darlington pair is necessary to drive loads directly. Consider the slower switching speeds inherent to Darlington outputs compared to standard transistors. Verify that the SOP-8 footprint aligns with the PCB layout constraints and thermal management needs of the design.
Part Context
Isocom Components specializes in providing alternatives to discontinued or industry-standard optocouplers. The PS2505 series serves as a replacement for similar devices from other manufacturers, offering tailored parameter selections to meet specific customer circuit design requirements while maintaining global industry certification standards.
Replacement Considerations
Potential substitutes include PS2501-1XSM for transistor output variants or PS2502-1XSM for comparable Darlington configurations. Verify pinout compatibility and electrical characteristics before substitution.
