Overview
The TLP127(PSION-TPR,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 phototransistor featuring an integrated base-emitter resistor. The device provides a collector-emitter voltage (VCEO) of 300V and supports an output current of 150mA. Key electrical parameters include a forward voltage drop of 1.15V, isolation voltage of 2500Vrms, and a DC reverse voltage of 5V. Operating temperatures range from -55°C to +100°C.
Feature Summary
- Integrates a gallium arsenide infrared LED with a Darlington phototransistor having an internal base-emitter resistor.
- Features high collector-emitter voltage capability suitable for demanding switching applications.
- Designed specifically for compact surface mount assembly processes.
Applications
- Programmable controllers
- DC-output modules
- Telecommunications equipment
Procurement Notes
Verify the specific suffix 'PSION-TPR' against official Toshiba documentation to confirm pinout and package dimensions, as non-standard suffixes may indicate regional or distributor-specific variations. Ensure compatibility with SOP-4 or MFSOP footprints depending on the exact mechanical drawing provided in the datasheet. Confirm RoHS compliance status directly from the manufacturer's latest release notes.
Selection Notes
Select this component when high gain is required due to the Darlington output structure, which offers higher current transfer ratios compared to standard transistor outputs. The integrated base-emitter resistor simplifies circuit design by reducing external component count. Verify that the 300V load voltage rating meets the system requirements and that the 2500Vrms isolation voltage satisfies safety standards for the intended application environment.
Part Context
This part belongs to Toshiba's TLP127 series of mini flat couplers. The series is characterized by small outline packages suitable for automated surface mounting. Variants within the series typically share the same optoelectronic core but differ in packaging styles such as SOP or MFSOP, and tape/reel configurations indicated by suffixes like TPR or F.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with generic Darlington output optocouplers only if electrical parameters and package dimensions match exactly, subject to rigorous validation.
