Overview
The TLP127(TAIKO-TPL,F) is a single-channel optocoupler featuring a gallium arsenide infrared LED and a Darlington phototransistor with an integrated base-emitter resistor. It provides high current transfer ratios, typically 1000% minimum, and supports collector-emitter voltages up to 300V. The device offers isolation voltages of 2500Vrms and operates within a temperature range of -55°C to 100°C. Key electrical parameters include a forward voltage of approximately 1.15V at 10mA, a maximum DC forward current of 50mA, and output currents up to 150mA. Rise and fall times are typically 40µs and 15µs respectively under standard test conditions.
Feature Summary
- Integrates a GaAs infrared LED with a Darlington phototransistor for high gain
- Includes an internal base-emitter resistor to ensure reliable turn-off
- Provides robust electrical isolation between input and output circuits
- Supports high collector-emitter voltage for versatile switching applications
Applications
- Programmable logic controllers (PLCs)
- DC-output modules in industrial automation
- Telecommunication equipment signal isolation
- Power supply control and feedback loops
Procurement Notes
Verify the specific suffix 'TAIKO' against official Toshiba Semiconductor and Storage documentation to confirm package type and compliance status. Ensure the component matches the required SOP-6 or equivalent surface-mount footprint. Cross-reference datasheet revisions to confirm electrical characteristics remain consistent with design requirements before finalizing procurement orders.
Selection Notes
Select this component when high current transfer ratio and reliable latching behavior are required due to the Darlington configuration. The integrated base-emitter resistor simplifies circuit design by preventing false triggering from noise. Consider the slower switching speed compared to transistor outputs when designing for high-frequency applications. Ensure adequate thermal management if operating near maximum power dissipation limits.
Part Context
This part belongs to Toshiba's mini flat coupler series, designed for surface mount assembly. It represents a compact solution for galvanic isolation in space-constrained PCB layouts. The series is widely recognized in industrial and telecommunications sectors for its reliability and standardized pin configurations, facilitating easy integration into existing designs.
Replacement Considerations
Public confirmed substitute part numbers: TLP126TPRF, TLP182(TPL,E). Verify compatibility regarding isolation voltage, current transfer ratio, and package dimensions before substitution.
