Overview
The PS2501AL-1-F3-W-A is a single-channel optically coupled isolator manufactured by Renesas Electronics Corporation. It integrates a Gallium Arsenide (GaAs) infrared emitting diode with an NPN silicon phototransistor to provide electrical isolation. The device offers a high isolation voltage of 5000Vrms and supports a maximum collector-emitter voltage of 70V. It operates within a temperature range of -55°C to +100°C, featuring a typical current transfer ratio of up to 260% at 5mA input current. The component is housed in a 4-SMD gull-wing package suitable for surface mount applications.
Feature Summary
- Integrates a GaAs LED and NPN phototransistor for optical signal transmission
- Provides robust electrical isolation with 5000Vrms dielectric strength
- Supports wide operating temperature range from -55°C to +100°C
Applications
- Industrial control systems requiring galvanic isolation
- Measurement equipment input stages
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'W-A' against the official Renesas datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status through the manufacturer's latest documentation. Check product lifecycle status as availability may be limited or discontinued depending on the region and date of inquiry.
Selection Notes
Select this component when high isolation voltage and wide temperature operation are required in a compact surface-mount form factor. Ensure the input forward current and output collector current requirements align with the specified limits. Consider the rise and fall times for signal integrity in switching applications.
Part Context
This part belongs to the PS2501A(L)-1 series of single-channel optocouplers. It is designed for general-purpose isolation tasks where cost-effectiveness and reliability are prioritized. The series typically includes variants with different packaging options such as DIP and SMD configurations.
Replacement Considerations
Consult the official Renesas replacement guide for direct substitutes. Verify pinout compatibility and electrical parameters before integrating alternative components into existing designs.
