Overview
The PS2801A-1-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates an AlGaAs light-emitting diode and an NPN silicon phototransistor within a compact SSOP-4 surface-mount package. The device provides high isolation voltage of 2500 Vrms and supports a maximum collector-emitter voltage of 70 V. Key electrical parameters include a forward current of 30 mA, forward voltage of 1.4 V, and power dissipation of 60 mW. It operates reliably within a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- Compact SSOP-4 surface-mount package designed for high-density PCB layouts
- Integrated ambient light shielding to ensure stable operation in various environments
- Compliance with RoHS standards for environmentally friendly manufacturing
Applications
- Industrial control systems requiring galvanic isolation
- Signal interface circuits in measurement instruments
- Power supply feedback loops for noise immunity
- Solid-state relay driver applications
Procurement Notes
Verify the specific suffix F3 indicates tape and reel packaging configuration when sourcing components. Confirm that the part number aligns with current Renesas product lifecycle status, as availability may vary based on regional distribution channels and stock levels. Ensure all ordering documentation matches the exact manufacturer part number to avoid substitution errors.
Selection Notes
Select this component for applications requiring single-channel isolation with moderate speed requirements. The SSOP-4 package is suitable for space-constrained designs. Consider the 70 V collector-emitter voltage rating for low-voltage switching tasks. Evaluate thermal management needs given the 60 mW power dissipation limit in enclosed environments.
Part Context
This device belongs to the PS2801A series of high-isolation voltage photocouplers. It shares architectural similarities with other members like the PS2801A-4-A but differs in channel count and pin configuration. The series is characterized by its use of AlGaAs LEDs for improved coupling efficiency compared to older GaAs variants, offering enhanced performance in standard industrial optocoupler applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs before considering alternative sources or generic equivalents.
