FQN1N50CBU-VB Product details
Back to previous pageProduct introduction：
Still worried about high leakage current and insufficient reliability in high-voltage auxiliary power supplies? Let VBsemi FQN1N50CBU-VB solve your problems! This TO92-packaged N-MOSFET, though compact in size, can withstand 650V high voltage, paired with a 1A current capability, specifically designed for high-voltage low-power scenarios. The Planar process provides stable switching characteristics and excellent voltage resistance performance. The 6667mΩ on-resistance is a reasonable level for high-voltage devices, effectively balancing losses and cost, making it a 'worry-free choice' for high-voltage auxiliary circuits and small appliance power supplies.
