TLP127(TPL,F)

Overview

The TLP127(TPL,F) is a surface-mount optocoupler featuring an integrated GaAs infrared LED and a Darlington phototransistor with a built-in base-emitter resistor. It provides one channel of isolation with a rated voltage of 2500 Vrms. The device supports a collector-emitter voltage (VCEO) of 300 V, a forward current (If) of 50 mA, and an output current of 150 mA. Key timing parameters include a rise time of 40 µs and a fall time of 15 µs at specified test conditions. The unit operates within a temperature range of -55 °C to +100 °C and dissipates up to 200 mW.

Feature Summary

Integrates a Darlington phototransistor with a built-in base-emitter resistor for simplified circuit design
Provides high isolation capability with a rated insulation voltage of 2500 Vrms
Features low leakage current in the nanoampere range for reliable signal integrity
Complies with IEC 61000-4-2 electrostatic discharge standards for enhanced robustness

Applications

Programmable logic controllers
DC-output modules
Telecommunications equipment

Procurement Notes

Verify the specific suffix configuration against the manufacturer's datasheet to ensure compatibility with required packaging and lead-free specifications. Confirm that the selected variant matches the intended surface-mount assembly process and thermal management requirements for the target application environment.

Selection Notes

Select this component when high current transfer ratio and simple drive circuits are required due to the integrated base resistor. Ensure the operating voltage does not exceed the 300 V collector-emitter limit. Consider the slower switching speed compared to logic output types when designing for high-frequency applications.

Part Context

This part belongs to Toshiba's Miniflat Coupler series, designed for compact surface-mount applications. It utilizes a plastic package to provide electrical isolation between input and output circuits. The series is engineered for general-purpose industrial and commercial electronics where reliable DC signal transmission is necessary.
