TLP291-4(V4GBTPE

Transistor, Photovoltaic Output Optoisolators Overview

The TLP291-4(V4GBTPE is a quad transistor output optoisolator manufactured by Toshiba Semiconductor and Storage. It integrates four independent channels within a 16-SOIC package, providing 2500Vrms isolation voltage. The device features a maximum collector-emitter voltage of 80V and a continuous collector current of 50mA per channel. Typical switching times are 2µs for rise and 3µs for fall. The operating temperature range spans from -55°C to 110°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (V4GB) against official Toshiba documentation to confirm compliance requirements and material composition. Ensure the ordering code matches the exact package width and lead form specified in the datasheet. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS and halogen-free status if required by project specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are needed in a compact footprint. The 16-SOIC package facilitates automated assembly. Consider the 2500Vrms isolation rating for applications demanding basic insulation levels. Evaluate the 50mA output current capability against load requirements. Verify that the 80V collector voltage meets the circuit's maximum potential differences.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the TLP291 series of transistor output optocouplers. The quad configuration distinguishes it from single-channel variants like the TLP291. The V4GB suffix typically indicates specific regulatory approvals or material specifications defined by Toshiba. It serves as a solution for space-constrained designs requiring multiple isolated signals.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements must match the 16-SOIC package, 4-channel configuration, and 2500Vrms isolation rating. Verify pinout compatibility before substitution. Check that the replacement device offers equal or superior current transfer ratio and switching speed characteristics.
