Typical Applications
BSC360N15NS3GATMA1 is suitable for 6 applications: 48V Telecom Bus Converter, Synchronous Rectification in Isolated DC-DC, Solar Micro-Inverter Power Stage, Motor Drive Half-Bridge, Hot-Swap and ORing Controller, Automotive 48V Mild-Hybrid Bus Converter.
48V Telecom Bus Converter
The BSC360N15NS3GATMA1's 150 V VDS rating and 36 mOhm RDS(on) suit primary-side switching in isolated 48 V telecom bus converters, where rectified input voltages reach 75 V and PFC stages push the rail up to 400 V. Synchronous rectification on the secondary side benefits from the device's low gate charge and fast switching transitions, enabling LLC and active-clamp topologies at 200-500 kHz. The SuperSO8 footprint simplifies thermal layout, with a single exposed drain pad sinking heat into 1-2 square inches of inner-layer copper.
Recommended
Synchronous Rectification in Isolated DC-DC
In isolated DC-DC stages using push-pull, half-bridge, or full-bridge topologies, the BSC360N15NS3GATMA1 functions as the synchronous rectifier MOSFET on the secondary side, replacing lossy Schottky diodes. With 36 mOhm RDS(on), conduction loss at 20 A is 14.4 W versus 25-30 W for a typical Schottky, a 40-50% efficiency improvement. The OptiMOS 3 process minimizes body-diode reverse recovery, reducing dead-time losses and EMI spikes across the isolation barrier.
Recommended
Solar Micro-Inverter Power Stage
Micro-inverters and string inverters with 100-150 V DC bus rails use the BSC360N15NS3GATMA1 in H-bridge and totem-pole stages, switching at 50-100 kHz to drive toroidal or EI transformers. The 33 A continuous drain current supports single-module micro-inverter outputs up to 1.5 kW per phase, while the 150 V rating absorbs transient ringing from transformer leakage inductance. Infineon's OptiMOS 3 reliability data and 100% Rg testing support the long-life requirement of solar installations.
Recommended
Motor Drive Half-Bridge
The BSC360N15NS3GATMA1 is well-matched to 100-150 V brushed and stepper motor half-bridge drives, where the 33 A continuous rating and 36 mOhm RDS(on) minimize heat generation in PWM switching at 20-50 kHz. The low gate charge reduces driver losses, enabling compact gate-drive designs around IRS2302 or IRS2114 half-bridge drivers. The SuperSO8 footprint allows high-density PCB layouts for multi-axis CNC and robotics motion controllers.
Recommended
Hot-Swap and ORing Controller
Hot-swap controllers and ORing circuits in 48 V server backplanes benefit from the BSC360N15NS3GATMA1's 36 mOhm RDS(on) and 150 V avalanche rating. The device handles inrush currents during board insertion while the controller's soft-start regulates the gate ramp. Its low conduction loss reduces the steady-state heat dissipation in always-on ORing applications, where two supplies share a load.
Recommended
Automotive 48V Mild-Hybrid Bus Converter
Mild-hybrid automotive 48 V bus converters use the BSC360N15NS3GATMA1 as the primary switching element in bidirectional DC-DC stages between 12 V and 48 V rails. The 150 V VDS handles 48 V bus transients up to 70 V during load-dump events, and the SuperSO8 package supports AEC-Q101-like manufacturing flow though this specific part is not AEC-qualified. Designers should select the automotive-grade variant for production deployments requiring full Q101 compliance.

Key Differentiators
- Lowest RDS(on) in Infineon's 150 V SuperSO8 OptiMOS 3 family (vs BSC520N15NS3G)
- OptiMOS 3 process gives best-in-class figure of merit (vs SiR872ADP-T1-GE3)
- Pin-compatible with industry-standard SO-8 5x6 footprint (vs DPAK/TO-252 alternatives)
Design Notes
Estimated: at ID = 20 A continuous and RDS(on) = 40 mOhm (hot), conduction loss is 16 W. With SuperSO8 mounted on 1 square inch of 2 oz copper top-layer plus 9-via array to bottom layer, expected theta_JA is approximately 45-50 C/W, giving a junction rise of 720-800 C above ambient. A 25°C ambient yields Tj near 100°C, well inside the 150°C limit. For sustained > 20 A loads, add a top-side heatsink or expand copper to 2 square inches to halve theta_JA.
The exposed bottom pad is the drain and primary thermal path. Use a continuous copper pour under the device spanning at least 1 square inch, with a 5x6 thermal via array (0.3 mm drill, 1.0 mm pitch) connecting top, inner, and bottom layers. Solder paste stencil aperture should be 1:1 with the pad to ensure proper void-free solder joint, which directly impacts both thermal resistance and electrical connection to drain.
Place the gate driver within 10 mm of the gate pin to minimize gate-loop inductance. Use a 10 ohm gate resistor with a small ferrite bead to dampen parasitic ringing; the BSC360N15NS3GATMA1's low Qg keeps switching losses acceptable. Keep the source return path direct to the driver ground Kelvin pin to avoid source-inductance-induced turn-on glitches. A 100 kohm gate-source pull-down resistor prevents inadvertent turn-on during power-up.
Do not exceed 150 V VDS even for transient spikes: ringing from transformer leakage inductance can easily double the nominal bus voltage. Add an RC snubber (10-22 ohm + 1-2 nF) across the drain-source to absorb leakage energy. Confirm VGS stays below the +/- 20 V absolute maximum rating, especially during avalanche events where the gate can couple from drain via Cgd. Below 6 V VGS the device operates in the Miller plateau and RDS(on) rises sharply, so drive the gate with at least 10 V for full enhancement.
Compliance Information
