Overview
The TLP127(YASK-TPL,F) is a mini flat coupler manufactured by Toshiba Semiconductor and Storage, designed for surface mount assembly. It integrates a gallium arsenide infrared emitting diode with a Darlington photo transistor featuring an integral base-emitter resistor. The device provides high isolation voltage of 2500Vrms and a collector-emitter voltage of 300V. Key electrical parameters include a minimum current transfer ratio of 1000%, a maximum forward current of 50mA, and a typical rise time of 40us. It operates within a temperature range of -55°C to 100°C.
Feature Summary
- Integrates a GaAs infrared LED with a Darlington phototransistor having a built-in base-emitter resistor for high gain.
- Provides robust electrical isolation suitable for safety-critical applications with high breakdown voltage capabilities.
- Features a compact small outline package optimized for automated surface mount technology processes.
Applications
- Programmable controllers
- DC-output modules
- Telecommunication equipment
Procurement Notes
Verify the specific suffix 'YASK' against official Toshiba documentation to confirm it denotes a valid manufacturing or packaging variant distinct from standard TPL or U designations. Ensure that any requested substitute components match the original pinout, isolation ratings, and electrical characteristics precisely to maintain system integrity.
Selection Notes
Select this component when high current transfer ratio and strong isolation are required in a compact form factor. The integrated base-emitter resistor simplifies circuit design by reducing external component count. Consider the switching speed limitations inherent to Darlington outputs when designing for high-frequency signal transmission applications.
Part Context
This part belongs to Toshiba's mini flat coupler series, which focuses on providing reliable optocoupling solutions in space-constrained environments. The TLP127 model specifically targets applications needing high isolation and significant output drive capability, distinguishing it from faster but lower-gain logic output variants within the broader product family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative devices by matching critical specifications such as isolation voltage, current transfer ratio, and package dimensions before implementation.
