The OptiMOS technology uses charge-compensated superjunction structures to achieve the very low specific on-resistance (RDS(on) x Area) that enables high-efficiency power conversion. The 36A continuous current rating and 175C maximum junction temperature support demanding applications. The SuperSO-8 (PG-TDSON-8) package features an exposed die pad for efficient heat dissipation to the PCB, with a junction-to-mounting base thermal resistance of approximately 1.5 K\/W. The 38 nC gate charge supports switching frequencies up to several hundred kHz.","working_principle":"The BSC109N10NS3G uses Infineon's OptiMOS superjunction technology where alternating N and P columns in the drift region provide lateral depletion during the blocking state, supporting the 100V rating with a thinner drift region than conventional MOSFETs. This thinner drift region reduces on-resistance to 10.9 mOhm. The device is constructed with a vertical DMOS cell structure where the current flows vertically from the source (top) through the channel and drift region to the drain (bottom\/die pad). The SuperSO-8 package bonds the die pad directly to the PCB copper for thermal management. The 38 nC total gate charge determines the switching speed and gate drive power: P_gate = Qg x VGS x f_sw. At 100 kHz switching frequency with 10V gate drive, the gate drive power is approximately 38 mW.","pin_description":"
