The TLP127 is a mini-flat coupler consisting of a gallium arsenide infrared emitting diode optically coupled to a darlington photo transistor with an integral base-emitter resistor. It provides a collector-emitter voltage of 300V and an isolation voltage of 2500Vrms. The device features a current transfer ratio of 1000% minimum and operates within a temperature range of -55°C to +100°C.
Verify the specific suffix MAT-L-TPL,F against official Toshiba documentation to confirm package type, tape/reel specifications, and lead-free status. Ensure compatibility with surface mount assembly processes and check for UL recognition file numbers if safety certification is required for the end application.
Select this component when high current transfer ratio and low saturation voltage are required for DC signal isolation. The integrated base-emitter resistor simplifies circuit design by reducing external component count. Verify thermal management requirements as power dissipation limits apply during operation.
This part belongs to the TLP127 series of mini-flat couplers manufactured by Toshiba Semiconductor and Storage. The series is designed for surface mount applications, offering compact packaging solutions for industrial and communication systems requiring reliable galvanic isolation.
