Overview
The TLP120(GR-TPL,F) is a mini flat coupler featuring a photo transistor optically coupled to two inverse-parallel connected gallium arsenide infrared emitting diodes. This configuration enables direct AC input current operation without external rectification. Key electrical parameters include a minimum collector-emitter voltage of 80 V, a minimum current transfer ratio of 50% (Rank GB: 100%), and a minimum isolation voltage of 3750 Vrms. The device is designed for surface mount assembly in small outline packages.
Feature Summary
- Dual inverse-parallel GaAs infrared emitting diodes enable direct AC input signal detection
- Integrated photo transistor output provides high-speed switching capability
- High insulation voltage rating ensures reliable signal isolation between circuits
Applications
- AC/DC input modules for programmable controllers
- Telecommunication equipment interface circuits
- Direct AC signal sensing applications
Procurement Notes
Verify the specific suffix GR-TPL,F against official Toshiba Semiconductor and Storage documentation to confirm package type and compliance status. Ensure the component matches the required isolation voltage and current transfer ratio ranks for your circuit design. Cross-reference ordering information with authorized distributors to avoid counterfeit parts.
Selection Notes
Select this component when direct AC input handling is required without additional rectifying components. The dual-diode input structure simplifies circuit design for AC signals. Verify that the 80 V collector-emitter voltage rating meets the load requirements. Consider the surface mount package constraints during PCB layout planning.
Part Context
This part belongs to the TLP120 series of mini flat couplers manufactured by Toshiba Semiconductor and Storage. The series is characterized by compact surface mount packaging and integrated dual-diode inputs for AC compatibility. It serves as a specialized optocoupler solution for industrial and telecommunications control systems requiring robust isolation.
