Overview
The PS2801-1-F3-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and provides high isolation voltage of 2500 Vrms. The device operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a power dissipation of 180 mW. The input forward current is rated at 5 mA with a forward voltage of 1.1 V. The component is housed in a compact SSOP-4 package.
Feature Summary
- Provides high insulation voltage for effective signal isolation between circuits
- Utilizes a small and thin SSOP package design suitable for high-density mounting
- Features NPN phototransistor output configuration for digital signal transmission
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix K-A against official Renesas documentation to confirm pin pitch and packaging details. Confirm availability status as distribution channels may list this part as discontinued or limited stock. Ensure the ordering code matches the required lead time constraints for production schedules.
Selection Notes
Select this component when a single channel of isolation with 2500 Vrms rating is required in a compact form factor. Consider the 5 mA input drive requirement and 50 mA output capability for circuit design. Verify thermal management needs given the 180 mW power dissipation limit in the SSOP-4 package.
Part Context
This part belongs to the PS2801 series of transistor output optocouplers from Renesas. The series is designed for general-purpose isolation applications. The PS2801-1 variant specifically denotes a single-channel configuration. The F3 suffix typically indicates a specific tape and reel packaging option, while K-A may denote specific manufacturing codes or regional variants.
Replacement Considerations
Check for direct replacements such as PS2801-1-V-F3-P-A or PS2801A-1-F3-P-A. Verify pin compatibility and electrical parameter equivalence before substitution. Note that some variants may be discontinued or recommended for new designs differently.
