Overview
The TLP127(U,F) is a small outline optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates an aluminum gallium arsenide infrared emitting diode with a Darlington-connected phototransistor featuring an integrated base-emitter resistor. The device provides electrical isolation with a rated voltage of 2500 Vrms. Key electrical parameters include a collector-emitter breakdown voltage (VCEO) of 300 V, a forward voltage (Vf) of 1.3 V, and a maximum power dissipation of 200 mW. The unit operates within a temperature range of -55 °C to +110 °C.
Feature Summary
- Integrates an infrared LED with a Darlington phototransistor for high current transfer ratio
- Includes an internal base-emitter resistor to optimize switching speed and thermal stability
- Provides robust signal isolation between input and output circuits
Applications
- Programmable logic controllers
- DC output modules
- Telecommunications equipment
Procurement Notes
Verify the specific suffix configuration against the official datasheet to ensure compatibility with required packaging and lead-free standards. Confirm that the component meets all necessary regional regulatory certifications for the intended deployment environment before finalizing procurement orders.
Selection Notes
Select this component when high gain is required for driving loads directly without additional amplification stages. The integrated resistor simplifies circuit design by reducing external component count. Ensure the application voltage does not exceed the 300 V collector-emitter rating under all operating conditions.
Part Context
This device belongs to Toshiba's Miniflat Coupler series designed for surface mount assembly. It utilizes a compact plastic package to facilitate automated PCB placement while maintaining high isolation performance suitable for industrial control systems and communication interfaces requiring galvanic separation.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings if considering alternative manufacturers.
