PS2501A-1-L-A

Overview

The PS2501A-1-L-A is a single-channel transistor output optoisolator manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN silicon phototransistor within a surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a collector-emitter voltage of 80V, a maximum forward current of 50mA for the LED, and a typical rise/fall time of 3µs/5µs. The unit operates within a temperature range of -55°C to +100°C.

Feature Summary

High isolation voltage capability of 5000 Vrms for robust circuit separation
Integration of GaAs LED with NPN silicon phototransistor for efficient optical coupling
Surface mount gull-wing package design suitable for automated assembly

Applications

Industrial control systems requiring galvanic isolation
Signal transmission across isolated ground planes
Power supply feedback loops for noise immunity

Procurement Notes

Verify the specific suffix 'L-A' against official datasheets to confirm surface mount gull-wing configuration. Confirm end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans. Ensure compatibility with existing PCB footprints designed for this specific package variant.

Selection Notes

Select this component when surface mount technology is required for single-channel isolation applications. Compare performance metrics such as CTR and switching speed against through-hole alternatives if space constraints are critical. Verify that the 5000 Vrms isolation rating meets the safety standards of the target application environment.

Part Context

This part belongs to the PS2501 series of high isolation voltage optoisolators. The series includes both through-hole DIP variants and surface mount versions. The 'L' suffix typically denotes the lead bending type (gull-wing) for surface mounting, distinguishing it from standard DIP packages in the same family.
