NCE Power Super Junction Distributor | 500 V to 650 V

BeiLuo supplies genuine NCE Power Super Junction MOSFETs, the high-voltage switches that make efficient offline power conversion possible. A Super Junction structure uses charge balance to lower on-resistance sharply for a given voltage, so a 500 V or 650 V switch conducts with much less loss than a conventional planar device. NCE Power's SJ-III and SJ-IV platforms cover 500 V to 650 V and beyond, with on-resistance values from about 70 milliohm in the higher-current parts, in packages that include TO-220F, TO-252, TO-251, TO-263 and TO-247. The SJ-III TF series adds an enhanced body diode reverse-recovery characteristic on top of the low on-resistance, ultra-low gate charge and fast switching of the platform, which reduces the reverse-recovery loss and EMI that a super-junction body diode can otherwise introduce in full-bridge, half-bridge and LLC resonant converters. That makes the family a strong fit for power-factor correction, switch-mode power supplies, UPS, PC power, telecom power and LED lighting. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you match the voltage class, on-resistance, package and body-diode behavior to your topology, then confirms stock and lead time. Selecting a Super Junction MOSFET means matching the voltage and current to your converter, choosing an on-resistance that meets the loss and thermal budget, and confirming the package for your cooling and board.
