TLP290(GR-TP,SE

Transistor, Photovoltaic Output Optoisolators Overview

The TLP290(GR-TP,SE is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a GaAs infrared emitting diode optically coupled to a phototransistor within a 4-pin SOIC package. The device supports AC or DC input currents up to 50 mA and provides an isolation voltage of 3750 Vrms. Key electrical parameters include a collector-emitter voltage of 80 V, a typical rise time of 2 µs, and a fall time of 3 µs. The GR rank ensures a minimum current transfer ratio of 100% at 5 mA input current.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (GR-TP,SE) to confirm the current transfer ratio grade and tape-and-reel packaging format. Ensure compatibility with existing PCB footprints, as the SOIC-4 package dimensions are standardized but pin configurations must be validated against schematic requirements. Confirm that the 3750 Vrms isolation rating meets the safety standards required for the target application environment.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when direct AC drive capability is required without additional rectification circuitry. The GR rank is appropriate for designs demanding a minimum current transfer ratio of 100%, ensuring robust signal transmission. Consider the 80 V collector-emitter voltage limit for load switching applications. Verify that the 50 mA maximum forward current aligns with the driving source capabilities and thermal management constraints of the system.
