BSC118N10NSGATMA1 개요
A power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled switch that uses an insulated gate to modulate current flow between source and drain terminals. MOSFETs are core building blocks of modern switched-mode power conversion, sitting below passive components and above raw silicon in the power-electronics hierarchy: MOSFET -> power switch -> SMPS -> AC-DC or DC-DC converter. The OptiMOS 2 generation specifically targets high-frequency SMPS and synchronous rectification in telecom, server, and computing power rails.
Key features of the BSC118N10NSGATMA1 include N-channel normal-level enhancement mode operation, excellent gate-charge x RDS(on) figure of merit (FOM), very low on-state resistance, 150 C maximum operating junction temperature, Pb-free lead plating, full RoHS compliance, JEDEC qualification for the target application, and halogen-free construction. The advanced trench cell architecture enables the lowest RDS(on) in class, minimizing conduction loss in 48 V telecom bus converters and 24 V industrial point-of-load regulators.
Typical applications include high-frequency DC-DC converters, synchronous rectification in isolated half-bridge and full-bridge converters, telecom 48 V bus converters, server and datacom VRM stages, motor-drive low-side switches, and battery protection in e-mobility and power-tool packs. The PG-TDSON-8-1 footprint is one of the most common power MOSFET packages in 48 V and 24 V rails, simplifying PCB layout reuse across related rails.
When designing with this device, ensure the gate drive voltage swings fully above the threshold (typically 10 V) to achieve the rated RDS(on). For high-current paths, stitch the exposed drain pad directly to a large copper pour to keep thermal resistance below the 50 C/W range and avoid thermal runaway above 100 W dissipation.

48 V Telecom Bus DC-DC Converter
The BSC118N10NSGATMA1 is well suited for 48 V telecom bus converters where its 100 V VDS rating provides comfortable margin above the nominal 48 V rail plus transient spikes. Its 71 A continuous drain current at Tc handles peak loads in half-bridge and full-bridge topologies. The OptiMOS 2 cell architecture achieves low RDS(on) at 10 V gate drive, reducing conduction loss in the primary-side switch. Placed as the primary switch in a phase-shifted full-bridge, it minimizes duty-cycle loss and improves overall efficiency. According to the Infineon OptiMOS datasheet, designers should target 100 kHz to 500 kHz switching to balance switching loss against magnetic size.

Synchronous Rectification in Isolated DC-DC
In isolated half-bridge and forward-converter secondary-side synchronous rectification, the BSC118N10NSGATMA1's trench technology and excellent FOM reduce body-diode conduction loss. The 100 V VDS rating covers 48 V-to-low-voltage isolated bus applications. With 71 A Tc-rated current capability, it can replace Schottky diode pairs in 12 V and 5 V output rails. The exposed drain tab enables direct PCB copper heatsinking, critical for continuous rectification current. Designers should pair it with a gate driver that enforces anti-cross-conduction dead-time to maximize efficiency.

설계 노트
Estimated: at VDS=48 V, ID=11 A continuous (TA), conduction loss alone is approximately P = ID^2 x RDS(on). With a typical OptiMOS 2 RDS(on) of about 6-8 milliohm at VGS=10 V, this yields ~0.7-1.0 W. The PG-TDSON-8-1 footprint with at least 1 square inch of top-layer copper and thermal vias to inner planes keeps theta_JA near 50 C/W, limiting junction rise to about 50 C above ambient at 1 W dissipation. For continuous 71 A operation (TC reference), forced air cooling or a dedicated heatsink tab is required.
Place the gate drive loop area as small as possible - keep gate trace width below 0.5 mm and gate-source return within 5 mm to minimize parasitic inductance. According to the Infineon OptiMOS datasheet, excessive gate-loop inductance causes ringing that can breach the VGS(max) rating of +/-20 V. Stitch the exposed drain pad directly to a top-layer copper pour with at least 6 thermal vias (0.3 mm drill) to inner planes for optimal heat extraction.
Do not operate the BSC118N10NSGATMA1 below its fully-enhanced gate voltage of 10 V - partial enhancement inflates RDS(on) and can cause thermal runaway in high-current paths. Verify VGS off-state is below 1 V (logic-level signals require a gate driver). For avalanche-prone applications (solenoid, motor), add a TVS clamp or RCD snubber across drain-source to clamp VDS transients below 100 V. Per the datasheet, the device is qualified for target SMPS applications but repeated avalanche should still be characterized.
