Overview
The PS2581AL2-F3-Q-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80V and a collector current of 50mA. The device provides 5000Vrms isolation voltage between input and output. Key electrical parameters include a forward voltage of approximately 1.17V, a saturation voltage of 300mV, and a typical rise/fall time of 3µs/5µs. The component operates within a temperature range of -55°C to +100°C and is housed in a surface-mount DIP-4 gull wing package.
Feature Summary
- Provides high-voltage isolation capability for signal transmission between isolated circuits
- Utilizes an NPN phototransistor output stage for digital switching applications
- Designed for wide operating temperature ranges suitable for industrial environments
Applications
- Industrial control systems requiring galvanic isolation
- Signal interface circuits in automation equipment
- Power supply feedback loops for noise immunity
Procurement Notes
Verify the specific suffix Q-A against the official Renesas datasheet to confirm compliance with any special quality or reliability requirements associated with that designation. Confirm the package type matches the design footprint, as variations exist within the PS2581 family. Check for recent Product Change Notices regarding manufacturing site or material updates. Ensure the component status is reviewed, as some variants may be marked as Not Recommended for New Designs.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation with moderate speed characteristics. Compare the 80V collector-emitter voltage rating against the load requirements. Verify that the 50mA collector current capacity exceeds the maximum expected load current. Consider the thermal dissipation limits if operating at the upper end of the temperature range. Ensure the 5000Vrms isolation rating meets the safety standards of the target application.
Part Context
This part belongs to the PS2581 series of transistor output optocouplers from Renesas. The series includes through-hole and surface-mount variants with different lead configurations. The AL2 designation typically indicates specific performance characteristics such as higher Current Transfer Ratio compared to standard versions. The F3 suffix denotes the surface-mount gull-wing package style.
Replacement Considerations
Direct substitutes include other PS2581AL2 variants with compatible pinouts, such as PS2581AL2-F3-A. Verify that replacement parts match the 80V Vceo and 50mA Ic specifications. Cross-reference with equivalent offerings from other manufacturers only if they meet the exact isolation voltage and package dimensions.
