PS2501L-1-E3

Overview

The PS2501L-1-E3 is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN phototransistor output and operates in a surface-mount gull-wing DIP-4 package. The device provides high isolation voltage of 5000 VRMS. Key electrical parameters include a collector-emitter saturation voltage maximum of 300 mV, a collector current rating of 50 mA, and a forward voltage of approximately 1.17 V at a forward current of 80 mA. The current transfer ratio ranges from 80% to 260% at a forward current of 5 mA. It supports a wide operating temperature range from -55°C to +100°C.

Feature Summary

• High isolation voltage capability for robust signal separation
• Surface-mount compatible gull-wing package design
• Wide operating temperature range for industrial environments

Applications

• Industrial control systems requiring signal isolation
• Noise suppression in communication circuits
• Half-duplex data transmission interfaces

Procurement Notes

Verify the specific suffix E3 against the manufacturer's latest documentation to confirm RoHS compliance status and lead-free material composition. Ensure the gull-wing package variant matches the intended PCB footprint requirements. Confirm availability through authorized distributors as standard stock levels may vary. Cross-reference the part number with official Renesas or CEL datasheets to validate pinout configuration before integration into new designs.

Selection Notes

Select this component when a single-channel isolation solution with surface-mount convenience is required. The NPN phototransistor output suits applications needing digital switching or analog signal transmission within specified limits. Consider the 5000 VRMS isolation rating for safety-critical circuits. Evaluate the current transfer ratio specifications to ensure adequate signal gain for the target load conditions without exceeding maximum ratings.

Part Context

This component belongs to the PS2501 series of high-isolation voltage multi-photocouplers. The PS2501L variant specifically denotes the lead-bending type suitable for surface mount technology, distinguishing it from the through-hole DIP versions like the PS2501-1. The series is designed for general-purpose isolation in various electronic systems.

Replacement Considerations

Public confirmed substitute part numbers: PS2501L-1-F3-A (Renesas). Verify functional equivalence regarding pinout and electrical characteristics before substitution.
