Overview
The PS2503L-1-M-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor in a DIP-4 Gull Wing package. Key electrical parameters include a 5000 Vrms isolation voltage, a collector-emitter saturation voltage of 250 mV maximum, and a current transfer ratio ranging from 100% to 200% at 1 mA forward current. The device supports a maximum collector current of 30 mA and operates within a temperature range of -55°C to +100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using optical coupling technology.
- Features fast switching capabilities with typical rise and fall times suitable for general-purpose applications.
- Designed for surface mount installation in a compact four-pin gull wing package.
Applications
- General-purpose signal isolation in industrial control systems
- Interface circuits for microcontrollers and logic devices
- Power supply feedback loops requiring galvanic isolation
Procurement Notes
Verify the specific suffix 'M-A' against official datasheets to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status and lead-free certification requirements prior to ordering. Ensure the supplier provides valid traceability documentation for the component batch.
Selection Notes
Select this component when a single-channel isolation solution with moderate speed and high isolation voltage is required. Compare the 250 mV saturation voltage and 30 mA collector current limits against load requirements. Consider the operating temperature range and package dimensions for PCB layout compatibility.
Part Context
This part belongs to the PS2503L series of transistor output optocouplers. The series typically includes variants with different packaging options such as standard DIP or surface mount configurations. The L-series designation often indicates specific insulation characteristics or package variations within the manufacturer's portfolio.
Replacement Considerations
Check for direct substitutes like PS2503L-1-A or PS2503-1 if pinout and electrical specifications match. Verify that alternative components meet the same isolation voltage and current transfer ratio requirements before substitution.
