STH110N10F7-2-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power DC-DC converter or motor drive module. Faced with a 100V bus voltage and a load current of up to 140A, ordinary MOSFETs either suffer from excessive conduction losses or frequent thermal runaway. The VBsemi STH110N10F7-2-VB is designed for this exact purpose—it combines 100V withstand voltage, 140A current capacity, and an ultra-low on-resistance of just 4mΩ in a standard TO263 (D2PAK) package, enabling efficient and reliable high-power power supply designs without the painful trade-off between heat dissipation and size.
