Overview
The PS2502-1-A is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN phototransistor output and utilizes a DIP-4 through-hole package. The device provides 5000 Vrms insulation voltage for signal isolation. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a typical current transfer ratio of 200%. It operates within a temperature range of -55°C to +100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes an NPN phototransistor for digital signal transmission
- Designed for robust performance in industrial control environments
Applications
- Industrial automation control systems
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific manufacturer source, as production rights for this part number have transitioned from California Eastern Labs (CEL) to Renesas Electronics. Confirm RoHS compliance status and lead times with authorized distributors, as availability may vary based on the current manufacturing entity and lifecycle stage.
Selection Notes
Select this component when a single-channel isolation barrier with moderate speed and high current transfer ratio is required. Ensure the application voltage does not exceed the 80 V collector-emitter rating. Consider the DIP-4 package constraints for PCB layout and verify thermal dissipation requirements against the specified power dissipation limits.
Part Context
This component belongs to the PS2502 series of Darlington output optocouplers. The series is characterized by high current transfer ratios suitable for driving loads directly. The PS2502-1-A specifically denotes the single-channel variant with standard DIP packaging, distinct from multi-channel or surface-mount versions within the same family.
Replacement Considerations
Cross-reference with PS2502L-1-A for surface-mount equivalents. Verify compatibility with PS2502-1-K-A regarding pinout and electrical characteristics before substitution.
