The SI5980DU-T1-GE3 is a single N-channel MOSFET manufactured by Vishay Siliconix. It utilizes TrenchFET technology and is housed in an 8-pin ChipFET package designed for surface mount applications. The device features a drain-source breakdown voltage of 60 V and a continuous drain current rating of 11.3 A. Its maximum on-resistance is specified at 19.5 mOhms, with a gate-source voltage limit of ±20 V. The component supports a junction temperature range from -55 °C to +150 °C and has a power dissipation capacity of 4.5 W.
This specific part number is listed as obsolete or end-of-life within available distribution records. Verification of current availability requires direct consultation with authorized manufacturers or distributors. Alternative sourcing strategies should be considered due to the discontinued status indicated in public supply chain data.
Designers requiring this component must verify compatibility with the 60 V drain-source voltage and 11.3 A current limits. The ChipFET-8 package dimensions and thermal characteristics must align with the target PCB layout. Since the part is marked obsolete, evaluating equivalent active components with matching electrical specifications is recommended for new designs.
The SI5980DU belongs to the Vishay Siliconix family of single N-channel MOSFETs utilizing TrenchFET technology. This series is characterized by low on-resistance and high efficiency. The specific model integrates these features into a compact surface-mount package suitable for various power management applications.
Public documentation lists SIS990DN-T1-GE3 as a recommended alternative for this component.
