Overview
The TLP127 is a mini flat coupler from 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. Key electrical parameters include a collector-emitter voltage of 300V (min), isolation voltage of 2500Vrms (min), and current transfer ratio of 1000% (min). The device supports DC input and offers UL recognition under file no. E67349.
Feature Summary
- Integrates a GaAs infrared LED with a Darlington phototransistor containing a built-in base-emitter resistor.
- Provides high collector-emitter voltage capability suitable for various switching applications.
- Features low leakage current characteristics typical of the series.
Applications
- Programmable controllers
- DC-output modules
- Telecommunication equipment
Procurement Notes
Verify the exact suffix configuration against official Toshiba documentation to ensure correct package type and lead-free status. Confirm that the specific variant matches the required isolation voltage and current transfer ratio specifications for the target circuit design before finalizing procurement orders.
Selection Notes
Select this component when a compact surface-mount solution with high gain is required. The integrated base-emitter resistor simplifies drive circuitry by reducing storage time effects. Ensure the application voltage does not exceed the 300V collector-emitter rating and consider the thermal dissipation limits within the SOP-6 package.
Part Context
This part belongs to the TLP12x series of mini flat couplers manufactured by Toshiba Semiconductor and Storage. These devices are characterized by their small outline packages suitable for automated surface mount assembly processes. The series provides reliable optical isolation between control and load circuits in industrial and consumer electronics.
Replacement Considerations
TLP126TPRF is listed as a discontinued alternative in public records; verify current availability and parameter compatibility if considering substitution.
