Overview
The PS2501-2SM is a high-density mounting phototransistor optically coupled isolator manufactured by Isocom Components. This component features a GaAs light emitting diode and an NPN silicon phototransistor configured for surface mount applications. It provides electrical isolation with a maximum forward voltage of 1.4V and supports a typical rise time of 4μs alongside a typical fall time of 3μs. The device operates within a temperature range of -30°C to 100°C and offers an isolation voltage of 5300Vrms. It is housed in a 16-pin PDIP SMD package, designed for robust signal transmission across isolated circuits.
Feature Summary
- Integrates a GaAs LED with an NPN silicon phototransistor for reliable optical signal transfer
- Provides high-voltage electrical isolation between input and output circuits
- Engineered for high-density surface mount PCB layouts
Applications
- Power supply units
- Telephone and fax equipment
- Programmable logic controllers
- FA/OA equipment
Procurement Notes
Verify the specific manufacturer source, as this part number may be produced by multiple entities including Renesas or Isocom. Confirm that the 16-pin configuration matches your design requirements, as standard variants often use fewer pins. Ensure compliance with RoHS standards and check for any specific tape-and-reel packaging requirements if automated assembly is planned.
Selection Notes
Select this component when high isolation voltage and fast switching speeds are required in a surface mount form factor. Consider the 16-pin layout for complex multi-channel or specialized interface needs compared to standard 4-pin or 8-pin alternatives. Evaluate thermal performance within the specified operating temperature range to ensure long-term reliability in industrial environments.
Part Context
This device belongs to the PS2501 series of high isolation voltage multi-photocouplers. The series includes various configurations such as single-channel and quad-channel options in both DIP and surface mount packages. These components are widely recognized for replacing legacy parts while offering enhanced performance metrics suitable for modern electronic designs.
Replacement Considerations
Compatible substitutes include the PS2501-2X from Isocom and the PS2501-2 from California Eastern Labs. Verify pinout compatibility and isolation ratings before substitution.
