Overview
The OCP-PCT114/E-TR is a single-channel transistor output optocoupler manufactured by Lumex Opto/Components Inc. It features a photovoltaic input configuration with a forward voltage of 1.2V. The device provides electrical isolation rated at 5000Vrms and utilizes surface mount packaging. Key performance metrics include a current transfer ratio ranging from 60% to 600% when tested at an input current of 2mA. The output channel supports a maximum continuous collector current of 50mA, making it suitable for applications requiring reliable signal transmission across isolated circuits.
Feature Summary
- Photovoltaic input configuration for high isolation voltage
- Transistor output stage capable of handling up to 50mA
- Wide current transfer ratio range for flexible gain control
- Surface mount package design for automated assembly
Applications
- Industrial process control systems
- Consumer electronics interface circuits
- Computer peripheral communication links
- General purpose signal isolation
Procurement Notes
Verify the specific suffix E-TR confirms the tape and reel packaging format required for automated pick-and-place manufacturing processes. Confirm that the 5000Vrms isolation rating meets the safety standards applicable to your target market. Ensure input drive currents remain within the specified limits to maintain the documented current transfer ratio performance characteristics.
Selection Notes
Select this component when a photovoltaic input is preferred over standard LED inputs for enhanced isolation capabilities. Consider the wide CTR range if variable gain compensation is necessary in the circuit design. Evaluate the surface mount footprint against available PCB space constraints. Compare the 50mA output capability against load requirements to ensure adequate drive strength for downstream components.
Part Context
This part belongs to the OCP series of optocouplers from Lumex Opto/Components Inc., designed for general-purpose isolation tasks. The series includes various output types and packaging options to suit different application needs. The E-TR designation specifically indicates the surface mount variant intended for high-volume production environments requiring consistent placement accuracy.
Replacement Considerations
The OCP-PCT114/C serves as a through-hole alternative within the same product family. Verify pinout compatibility and mechanical dimensions before substituting. Ensure the replacement option maintains the required 5000Vrms isolation rating and similar current transfer characteristics for equivalent circuit performance.
