SI085N10YL-TP-VB Product details
Back to previous pageProduct introduction：
Imagine this: You are designing a compact industrial control module and need a MOS transistor that can withstand 100V high voltage while stably outputting 4.3A current in a limited space. Ordinary devices are either too large or have high switching losses. VBsemi SI085N10YL-TP-VB is designed for this – it packs 100V withstand voltage, 4.3A current carrying capacity, and an on-resistance of only 100mΩ into the small SOT23-3 package, allowing high-voltage power supply design to balance performance and space.
