Overview
The PS2801C-1-P-A is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN phototransistor output and provides an insulation voltage of 2500 Vrms. The device operates within a temperature range of -55°C to +100°C. It is supplied in bulk packaging.
Feature Summary
- Provides high isolation voltage for signal transmission between isolated circuits
- Contains a single channel with NPN phototransistor output configuration
- Operates reliably across a wide industrial temperature range
Applications
- Signal isolation in industrial control systems
- Interface circuits requiring electrical isolation
- General purpose optocoupler applications
Procurement Notes
This component is listed as obsolete or end-of-life. Availability is restricted, and Mouser indicates that the product is not currently sold in certain regions. Verification of current stock status and alternative sourcing channels is required before procurement planning.
Selection Notes
Select this part only if legacy compatibility is mandatory due to its obsolete status. Verify that the single-channel NPN output and 2500 Vrms isolation meet system requirements. Consider newer Renesas equivalents like the PS2801 series for new designs, as support for this specific CEL-manufactured variant may be limited.
Part Context
The PS2801C-1-P-A belongs to the broader PS2801 family of optocouplers. While the family includes variants from Renesas Electronics (such as PS2801-4-A), this specific part number is attributed to CEL. It shares the core function of optical isolation but differs in manufacturer and potentially detailed specifications compared to the Renesas SSOP versions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements from other manufacturers should be verified against official datasheets.
