Overview
The PS2501AL-1-E3-H-A is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN phototransistor output with a maximum collector-emitter voltage of 70 V and a collector current rating of 30 mA. The device provides high isolation capability with an insulation voltage of 5000 Vrms. Electrical characteristics include a forward voltage of 1.4 V at a forward current of 30 mA, and a maximum collector-emitter saturation voltage of 300 mV. The unit operates within a temperature range of -55°C to +100°C and has a power dissipation rating of 150 mW.
Feature Summary
- Provides electrical isolation between input and output circuits using light transmission
- Features an NPN phototransistor output stage for digital signal switching applications
- Designed for surface mount installation in gull-wing packages
Applications
- Industrial control systems requiring circuit isolation
- Microprocessor interface circuits for signal coupling
- Solid-state relay driver applications
Procurement Notes
Verify the specific suffix E3 against the manufacturer datasheet to confirm compliance details and package variations. Confirm availability status as lifecycle changes may affect supply chain stability. Ensure the ordering part number matches the required tape and reel configuration for automated assembly processes.
Selection Notes
Select this component when a single channel of isolation with NPN output is required. Verify that the 70 V collector-emitter voltage meets the load requirements. Check that the 30 mA output current capability is sufficient for the driven circuit. Ensure the operating temperature range aligns with the environmental conditions of the final application.
Part Context
This part belongs to the PS2501A series of transistor output optocouplers from CEL. The series offers various packaging options including DIP and SMD configurations. The AL designation typically indicates specific performance characteristics or material composition within the product line. This model represents a surface mount variant designed for modern PCB assembly techniques.
Replacement Considerations
Direct replacements must match the 5000 Vrms isolation voltage and NPN output type. Verify pinout compatibility for the 4-SMD gull-wing package. Cross-reference with other manufacturers' PS2501 equivalents ensuring identical electrical parameters such as 30 mA collector current and 70 V breakdown voltage.
