Overview
The PS2501-1-M-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. The device provides electrical isolation of 5000Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 80V, a maximum forward current of 80mA, and a typical rise/fall time of 3µs/5µs. The Current Transfer Ratio ranges from a minimum of 80% to a maximum of 240% at a forward current of 5mA.
Feature Summary
- Integrates a GaAs light emitting diode and an NPN silicon phototransistor for signal transmission
- Provides high-voltage electrical isolation between input and output circuits
- Features fast switching characteristics suitable for digital signal applications
Applications
- Industrial control systems requiring galvanic isolation
- Measurement and testing equipment interfaces
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'M' against the official Renesas datasheet to confirm package dimensions and marking variations. Confirm component status as active or NRND before procurement planning. Ensure compliance with RoHS directives if required by the target application environment.
Selection Notes
Select this component when a single-channel transistor output optocoupler with 5000Vrms isolation is required. Consider the CTR range of 80% to 240% for logic interface compatibility. Verify that the 80V collector-emitter voltage rating meets the load requirements of the destination circuit.
Part Context
This part belongs to the PS2501 series of optocouplers, which are designed for general-purpose isolation applications. The series includes variants with different channel counts and packaging options. The PS2501-1-M-A specifically denotes a single-channel device in a PDIP package with specific manufacturing markings associated with the 'M' suffix.
Replacement Considerations
Cross-reference with PS2501-1-A or PS2501-1-W-A for similar performance profiles. Verify pinout compatibility and isolation voltage ratings before substitution. Check for any changes in Current Transfer Ratio specifications between original and replacement parts.
