TLP290-4(GB,E)

Transistor, Photovoltaic Output Optoisolators Overview

The Toshiba TLP290-4(GB,E) is a quad-channel photocopler featuring a gallium arsenide infrared emitting diode optically coupled to a photo-transistor. Housed in a compact SO16 package, it supports high-density surface mounting with an operating temperature range of -55°C to 110°C. Key electrical specifications include a minimum collector-emitter voltage of 80V and a guaranteed current transfer ratio of 100% (Rank GB) at 5mA input. The device provides a minimum isolation voltage of 2500Vrms and holds UL, CSA, and VDE approvals for industrial safety compliance.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Quad-channel configuration integrating four independent GaAs IRED and photo-transistor pairs within a single SO16 package
• High current transfer efficiency with Rank GB classification ensuring a minimum 100%CTR at 5mA input current
• Robust electrical isolation rated at 2500Vrms minimum with mechanical creepage and clearance distances of 5.0mm
• Wide operational temperature stability guaranteed from -55°C to 110°C for demanding industrial environments

Transistor, Photovoltaic Output Optoisolators Applications

• Programmable logic controllers requiring multi-channel signal isolation
• AC/DC input modules for industrial automation systems
• Hybrid integrated circuits necessitating compact high-density mounting
• Power supply units requiring galvanic isolation between control and output stages

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix designation when ordering, as variations such as (E) indicate VDE approval under EN60747-5-2 standards. Confirm package type availability, noting that standard distribution may utilize tube packaging while tape-and-reel options exist for automated assembly. Ensure compatibility with required insulation thickness and clearance distances for final equipment certification.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are required in a limited footprint. The 100% CTR rank offers superior signal fidelity compared to standard 50% variants. Consider the SO16 package dimensions against board space constraints. Verify thermal management requirements given the wide operating range and potential power dissipation in high-density applications.

Transistor, Photovoltaic Output Optoisolators Part Context

The TLP290-4 belongs to Toshiba's TLP series of transistor-output optocouplers designed for industrial applications. It complements single-channel variants like the TLP290 by providing four isolated paths in one package. This family targets programmable controllers and hybrid ICs where space efficiency and reliable isolation are critical design parameters.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include the TLP290-4(GB) for non-VDE applications or other quad-channel optocouplers with matching SO16 footprints and 80V collector-emitter voltage ratings. Ensure pinout compatibility and verify that alternative devices meet the same 2500Vrms isolation and -55°C to 110°C temperature specifications.
