TLP127TPRUF

Overview

The TLP127TPRUF is a surface-mount optocoupler from Toshiba Semiconductor and Storage, housed in a compact SOP-6 package. It integrates an aluminum gallium arsenide infrared emitting diode with a Darlington phototransistor output featuring an integrated base-emitter resistor. The device provides high current transfer ratios suitable for driving loads directly. Key electrical characteristics include a collector-emitter voltage of 300V, an isolation voltage of 2500 Vrms, and a maximum forward current of 50 mA. Typical switching times are 40 µs rise and 15 µs fall.

Feature Summary

Integrates a GaAlAs infrared LED with a high-gain Darlington phototransistor for enhanced sensitivity.
Features an internal base-emitter resistor to simplify circuit design and reduce component count.
Provides robust electrical isolation between input and output circuits for noise immunity.
Designed for surface mount assembly to support automated manufacturing processes.

Applications

Programmable logic controllers
DC output modules
Telecommunications equipment

Procurement Notes

Verify the specific suffix configuration against official Toshiba documentation to ensure compatibility with required packaging and lead-free standards. Confirm that the selected variant matches the intended application requirements regarding isolation voltage and thermal performance. Cross-reference datasheet specifications for operating temperature ranges before finalizing procurement decisions.

Selection Notes

Select this component when high gain is required to drive loads directly without additional amplification stages. The integrated base resistor simplifies biasing networks compared to standard phototransistors. Ensure the system voltage does not exceed the 300V collector-emitter rating. Consider the switching speed limitations inherent to Darlington structures when designing for high-frequency applications.

Part Context

This device belongs to Toshiba's Miniflat Coupler series, designed for space-constrained surface mount applications. It serves as a general-purpose isolation component within the broader TLP12x family. The technology leverages GaAlAs LEDs for efficient light emission and reliable long-term operation in industrial environments.
