SI2392BDS-T1-GE3-VB Product details
Back to previous pageProduct introduction：
**You are designing a compact industrial control module that needs to stably distribute a 100V bus voltage to downstream loads, while facing challenges of tight PCB area and limited heat dissipation conditions. Ordinary MOSFETs either lack sufficient voltage rating or are too large. The VBsemi SI2392BDS-T1-GE3-VB is designed for this—it integrates 100V withstand voltage, 4.3A current capability, and a low 100mΩ on-resistance into the small SOT23-3 package, making high-voltage power supply design and high-density layout no longer contradictory.**
