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-M-TPL against official Toshiba documentation to confirm lead time, packaging quantity, and RoHS compliance status. Ensure the ordering code matches the required tape and reel specifications for automated assembly processes.
Select this component for applications requiring high gain via the darlington configuration and robust electrical isolation. Consider the thermal derating requirements and maximum forward current limits when designing the input circuitry for reliable long-term operation.
This part belongs to the Toshiba mini-flat coupler series designed for surface mount assembly. It utilizes a gallium arsenide infrared LED paired with a darlington phototransistor to provide signal isolation in compact electronic designs.
