PS2501L-2-E3-A

Overview

The PS2501L-2-E3-A is a two-channel transistor output optocoupler manufactured by CEL. It features an isolation voltage of 5000 Vrms and utilizes DC input with NPN phototransistor outputs. The device operates within a temperature range of -55°C to +100°C. Key electrical parameters include a collector-emitter saturation voltage of 300 mV maximum, a collector current of 50 mA, and a forward voltage of 1.4 V. The component is housed in an 8-SMD surface mount package.

Feature Summary

Provides high-voltage electrical isolation between input and output circuits
Integrates two independent channels for dual-signal transmission
Utilizes NPN phototransistor output configuration for digital switching

Applications

Industrial control systems requiring signal isolation
Power supply feedback loops
Microcontroller interface circuits

Procurement Notes

Verify the specific suffix E3-A against official datasheets to confirm lead-free compliance and package variant. Confirm availability status as distribution data indicates limited stock or obsolete status for related PS2501 variants. Ensure the supplier provides valid traceability documentation matching the manufacturer's specifications before finalizing procurement orders.

Selection Notes

Select this component when dual-channel isolation is required in a compact surface-mount footprint. Compare the 5000 Vrms isolation rating against system safety requirements. Evaluate the 50 mA collector current capability against load demands. Consider the -55°C to +100°C operating range for environmental suitability compared to standard industrial temperature grades.

Part Context

This part belongs to the PS2501 series of high-isolation voltage photo couplers from CEL. The series includes both DIP and SMD variants, such as the PS2501L-2-E4-A. The product line is designed for applications demanding robust galvanic isolation. Related components include single-channel versions like the PS2501AL-1-F3-W-A.
