PS2501-1-W-A

Overview

The CEL PS2501-1-W-A is a single-channel transistor output optocoupler designed for high-voltage isolation applications. It features an NPN phototransistor output and operates with a DC input type. The device provides a robust isolation voltage of 5000Vrms, ensuring safety in demanding environments. Key electrical parameters include a maximum collector-emitter voltage of 80V, a collector current of 50mA, and a forward voltage of 1.17V at a typical forward current of 5mA. The unit is housed in a standard 4-DIP package with a lead pitch of 7.62mm (0.300 inches). It supports a wide operating temperature range from -55°C to +100°C and has a power dissipation rating of 150mW.

Feature Summary

• Provides 5000Vrms insulation voltage for reliable high-voltage isolation between input and output circuits.
• Utilizes an NPN phototransistor output configuration suitable for digital signal transmission.
• Engineered for operation across an extended industrial temperature range from -55°C to +100°C.

Applications

• Industrial control systems requiring galvanic isolation
• Automotive electronic circuits for noise immunity
• Power supply feedback loops for safety compliance

Procurement Notes

Verify the specific suffix 'W-A' against the manufacturer's latest datasheet to confirm pinout compatibility and package dimensions. Ensure that the required isolation voltage ratings align with your system's safety standards. Check for any RoHS compliance documentation if environmental regulations apply to your deployment. Confirm availability status as distribution channels may vary by region.

Selection Notes

Select this component when a single-channel transistor output is required with high isolation voltage capabilities. Consider the 80V collector-emitter voltage limit and 50mA output current capacity for load matching. The 4-DIP through-hole package is suitable for prototyping or PCB designs accommodating larger footprints. Evaluate the rise and fall times if high-speed switching is necessary for your application timing constraints.

Part Context

This part belongs to the CEL PS2501 series of NEPOC (New Opto Coupler) devices. The series includes variants such as the PS2501-1-M-A and PS2501L-1, which offer different packaging options like gull-wing leads for surface mount technology. The PS2501-1-W-A specifically denotes the standard DIP package variant within this family, maintaining consistent electrical characteristics across the series while differing in mechanical form factor.

Replacement Considerations

Cross-reference with other PS2501-1 variants from CEL, such as the PS2501-1-M-A, if surface mount or different tape-and-reel packaging is preferred. Verify that substitute components maintain the same 5000Vrms isolation rating and NPN output configuration to ensure circuit functionality remains unchanged without redesigning the isolation barrier.
