Overview
The PS2505-2SMT&R is a surface-mount optically coupled isolator manufactured by Isocom Components. It features two infrared light-emitting diodes connected in inverse parallel and NPN silicon phototransistors within a space-efficient dual in-line plastic package. The device provides high isolation voltage of 5.3 kVrms and 7.5 kVpk. It supports AC or polarity-insensitive input signals. All electrical parameters are 100% tested during manufacturing. The component is designed for signal transmission between systems with different potentials and impedances, ensuring reliable optical isolation in compact electronic designs.
Feature Summary
- Dual-channel configuration with inverse parallel LED inputs
- High dielectric isolation capability for safety compliance
- AC input compatibility without polarity constraints
- Surface-mount packaging for automated assembly
Applications
- Computer terminal interfaces
- Industrial system controllers
- Telephone exchange equipment
- Signal transmission between isolated circuits
Procurement Notes
Verify the specific suffix SMT&R confirms surface-mount tape-and-reel packaging format. Confirm that the part number corresponds to the dual-channel variant rather than single or quad configurations. Ensure the manufacturer designation matches Isocom Components official documentation. Check for any custom electrical selection requirements if standard parameters do not meet circuit specifications. Validate compliance with relevant safety standards such as UL recognition before integration.
Selection Notes
Select this component when dual-channel isolation is required in a compact surface-mount footprint. Consider the 5.3 kVrms isolation rating for applications demanding high dielectric strength. Evaluate the AC input feature for polarity-insensitive driving circuits. Compare current transfer ratio requirements against application needs. Assess thermal management capabilities given the plastic package construction and power dissipation limits.
Part Context
The PS2505 series represents Isocom's high-density optocoupler lineup featuring AC-input response types. This specific model integrates two phototransistor channels within a single dual-in-line package. The series is engineered for industrial and telecommunications environments requiring robust signal isolation. Isocom Components offers various packaging options including through-hole and surface-mount variants within this family.
Replacement Considerations
PS2505-2 is the standard through-hole equivalent. PS2505-2SM indicates surface-mount without reel packaging. PS2505-4-E3-XXX and PS2505-4-E4-600 are related quad-channel variants. Verify pinout compatibility and isolation voltage ratings when substituting with other manufacturers' parts.
