Overview
The PS2802-1-A is a single-channel NPN Photodarlington output optocoupler manufactured by Renesas Electronics. It features a 4-pin SSOP surface-mount package with an 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 40V, a maximum forward current of 50mA, and a typical forward voltage of 1.1V. The current transfer ratio ranges from 200% at 1mA input. Switching characteristics specify rise and fall times of 200µs each.
Feature Summary
- High isolation voltage capability for safe signal transmission between circuits
- Darlington output configuration provides high current gain
- Compact surface-mount packaging suitable for automated assembly
Applications
- Industrial control systems requiring galvanic isolation
- Signal interface in microcontroller-based designs
- Power supply feedback loops
Procurement Notes
Verify the specific suffix and revision level against the official datasheet before ordering. Confirm availability status as this component may be subject to limited supply or end-of-life restrictions. Ensure the selected variant matches the required pinout and insulation standards for your application design.
Selection Notes
Select this component when high current transfer ratio is needed in a small footprint. Consider the 200µs switching speed limitations compared to standard phototransistors. Verify that the 40V collector-emitter voltage meets the load requirements. Check for alternative packages if higher channel counts are required.
Part Context
This part belongs to the PS2802 series of optocouplers from Renesas. The series includes variants with different channel counts and output types. The PS2802-1-A specifically denotes a single-channel device with NPN Darlington output. It is designed for general-purpose isolation applications where moderate speed and high gain are prioritized.
Replacement Considerations
Check for PS2802-1-K-A or PS2802-1-V-F3-A as potential functional equivalents within the same family. Verify pin compatibility and electrical specifications before substitution. Consult the manufacturer's cross-reference guide for approved replacements.
