TLP127(TPR,F)

Overview

The TLP127(TPR,F) is a single-channel DC-input optocoupler featuring an integrated GaAlAs infrared LED and a Darlington phototransistor output with a built-in base-emitter resistor. It provides high current transfer ratio for efficient signal transmission. The device offers 2500 Vrms isolation voltage and supports a collector-emitter voltage of 300V. Key electrical parameters include a forward voltage of 1.15V, maximum forward current of 50mA, and output current of 150mA. Rise and fall times are typically 40µs and 15µs respectively at 10mA drive and 100Ω load. Operating temperature range spans from -55°C to +100°C.

Feature Summary

Integrates a GaAlAs infrared LED with a Darlington phototransistor output structure
Includes a built-in base-emitter resistor on the phototransistor for simplified circuit design
Provides high isolation voltage capability for safe signal transmission between circuits
Features low leakage current characteristics suitable for sensitive detection applications

Applications

Programmable logic controllers (PLCs)
DC-output modules in industrial automation systems
Telecommunications equipment interface circuits
Signal isolation in measurement and control devices

Procurement Notes

Verify the specific suffix designation against the manufacturer's latest datasheet to confirm pinout compatibility and packaging type. Ensure that the selected variant matches the required isolation voltage ratings and thermal performance specifications for the intended operating environment. Cross-reference ordering codes with official Toshiba Semiconductor documentation to avoid substitution errors.

Selection Notes

Select this component when high gain is required due to the Darlington output configuration. Consider the slower switching speed compared to transistor outputs when designing for high-frequency applications. Verify that the input current limits are respected to maintain optimal current transfer ratio. Ensure the package style meets the PCB layout requirements for surface mount assembly.

Part Context

This part belongs to Toshiba's TLP127 series of small outline optocouplers designed for surface mount technology. The series utilizes a Miniflat or SOP-6 package format to provide compact isolation solutions. It represents a standard solution for general-purpose digital signal isolation where moderate speed and high gain are prioritized over rapid switching capabilities.
