Overview
The PS2501-2GRSM is a dual-channel optically coupled isolator manufactured by Isocom Components. It integrates a Gallium Arsenide (GaAs) infrared light emitting diode with two NPN silicon phototransistors on a single chip. The device utilizes a surface-mount SOP-8 package, designed for high-density mounting applications. Key electrical specifications include a maximum collector-to-emitter voltage of 80 V and an isolation voltage rating of 5300 Vrms. The typical rise time is 4 μs and the fall time is 3 μs. It operates within a temperature range of -30°C to 100°C.
Feature Summary
- Dual-channel configuration integrating two independent GaAs LED and NPN phototransistor pairs for compact signal isolation.
- High isolation voltage capability ensuring reliable separation between input and output circuits in noisy environments.
- Surface-mount SOP-8 packaging facilitates automated assembly and high-density PCB layout.
Applications
- Programmable logic controller (PLC) I/O modules
- Power supply feedback loops
- Telephone and fax equipment interfaces
Procurement Notes
Verify that the 'G' suffix in the part number corresponds to the specific tape-and-reel or tube packaging variant required for your manufacturing line. Confirm that the SOP-8 footprint matches your PCB design guidelines. Ensure compliance with RoHS directives if applicable to your region. Cross-reference the manufacturer's latest datasheet for any updates to mechanical dimensions or thermal characteristics before finalizing the bill of materials.
Selection Notes
Select this component when dual-channel isolation is required in a small form factor. The SOP-8 package is suitable for surface-mount technology lines. Consider the 80 V collector-emitter voltage limit for switching applications. Verify that the 5300 Vrms isolation rating meets the safety standards of the target system. Compare against standard industry replacements if lead times are critical.
Part Context
The PS2501 series represents a family of high-isolation voltage photocouplers from Isocom. The PS2501-2GRSM specifically denotes the dual-channel variant in a surface-mount package. This series is widely used as a replacement for discontinued multi-channel optocouplers. The GRSM designation typically indicates a specific packaging format, often related to reel or tube quantities, distinct from the through-hole DIP versions like the PS2501-2X.

FAQ
What is the difference between PS2501-2 and PS2501-2GRSM?
The PS2501-2 is the general part number for the dual-channel device. The PS2501-2GRSM specifies the surface-mount SOP-8 package variant, whereas other suffixes may indicate through-hole DIP packages.
Does the PS2501-2GRSM support AC input?
Yes, the internal GaAs LED can be driven by AC signals, similar to other variants in the PS2501 series, provided the forward voltage and current limits are respected.
