Typical Applications
BSC023N08NS5SCATMA1 is suitable for 6 applications: 48 V Telecom Point-of-Load Converters, Server & Hyperscale Data-Center Buck Converters, E-Forklift and AGV Motor Drives, Battery Management System (BMS) Protection FETs, Synchronous Rectification in Telecom AC-DC Adapters, Solar Inverter DC-Side Switches.
48 V Telecom Point-of-Load Converters
The BSC023N08NS5SCATMA1 is a strong fit for the synchronous-rectifier (SR) and main-switch positions in 48 V telecom isolated DC-DC bricks. Its 80 V VDS gives over 60% margin above a 48 V nominal bus while tolerating transient ringing, and the 2.3 mΩ typical RDS(on) at 10 V VGS keeps conduction loss below 1% at 50 A output. Placed on the secondary-side low-side SR, the device's 98 nC total gate charge supports 200-500 kHz switching typical in modern telecom converters, and the 0.72 K/W RthJC allows designers to drop heatsinks in favor of PCB copper.

Server & Hyperscale Data-Center Buck Converters
For 48 V-to-12 V or 48 V-to-1 V direct-conversion stages in hyperscale data centers, the BSC023N08NS5SCATMA1's 188 W power dissipation and 202 A continuous current let one part replace two paralleled 60-80 V competitors, reducing board area and BOM cost. The 0.72 K/W RthJC supports dense layouts with only top-side copper thermal relief, while the 6.8 nF Ciss and 74 pF Coss enable 500 kHz switching without exceeding 10 nC gate-drive losses. Source: Infineon OptiMOS 5 datasheet; design example patterns from Server System Infrastructure Consortium.

E-Forklift and AGV Motor Drives
Battery-electric forklift and AGV traction inverters operating from 48 V or 72 V battery packs benefit from the BSC023N08NS5SCATMA1's 80 V VDS, 202 A continuous current, and SuperSO8 DSC footprint. Used as the low-side switch in three-phase inverter legs driving 5-15 kW PMSM motors, the device's 2.3 mΩ RDS(on) cuts I²R losses and extends battery runtime by 4-6% versus higher-RDS(on) competitors. Its -55 °C to +175 °C junction range supports cold-warehouse and outdoor-deployed AGVs.
Recommended
Battery Management System (BMS) Protection FETs
For 48 V lithium-ion battery packs in e-mobility and stationary storage, the BSC023N08NS5SCATMA1 serves as the high-side or low-side protection FET, where its 80 V VDS comfortably exceeds 48 V nominal plus transient spike margins. The 2.3 mΩ RDS(on) minimizes pack-to-load voltage drop during 100-200 A peak discharge pulses, while the 98 nC Qg keeps BMS FET-driver power consumption below 50 mW.

Synchronous Rectification in Telecom AC-DC Adapters
The BSC023N08NS5SCATMA1 placed on the secondary-side synchronous-rectifier slot of a 90-265 VAC-to-48 VDC telecom adapter achieves >97% efficiency at 500 W output, thanks to the 2.3 mΩ RDS(on) and 188 W dissipation capability. The exposed-pad SuperSO8 DSC package allows direct attachment to the chassis ground plane for additional heatsinking in fan-less 1U adapters. Source: Infineon application note on 80 V SR design.
Recommended
Solar Inverter DC-Side Switches
In string-inverter DC-side disconnect and short-circuit protection circuits, the BSC023N08NS5SCATMA1 handles 60-80 VDC solar-array short-circuit currents up to its 202 A rating. The 80 V VDS provides adequate margin above Voc-cold of typical 60-cell residential strings. Designers benefit from the 0.72 K/W RthJC for fan-less outdoor enclosures, where the 175 °C junction limit supports high-ambient rooftop operation.

Key Differentiators
- Industry-leading 2.3 mΩ RDS(on) at 80 V in SuperSO8 DSC (vs BSC0902NSIATMA1)
- Dedicated Kelvin-source pin for high-frequency switching (vs ISC080N10NM6ATMA1)
- 0.72 K/W RthJC supports fan-less high-current designs (vs IPB020N10N5LFATMA1)
Design Notes
The PG-WSON-8-2 (SuperSO8 DSC) package achieves 0.72 K/W RthJC only when the exposed top-side and bottom-side pads are soldered to a continuous copper pour. Estimated: at PD = 5 W with a 4-layer 2 oz copper PCB and 1 square inch top-side copper, total RthJA is approximately 25-30 K/W, producing a 125-150 °C junction rise above ambient. Without the top pad soldered, RthJA can exceed 60 K/W, halving safe power dissipation.
Always connect the SuperSO8 DSC's pin 4 Kelvin-source to the gate-driver return path, not the power-source plane. The dedicated Kelvin pin suppresses common-source inductance that otherwise slows switching edges and causes drain-voltage overshoot. Route the gate-drive loop (gate-driver output -> pin 8 gate pad -> pin 4 Kelvin-source -> gate-driver return) as a tight, area-minimized loop less than 10 mm in perimeter.
Do not operate the BSC023N08NS5SCATMA1 above its 80 V VDS rating even for short transients - avalanche breakdown degrades RDS(on) over time. Add a transient-voltage suppressor or RC snubber (typically 10 Ω + 1 nF) across the drain-source if the layout inductance exceeds 10 nH. Estimated: at 100 A turn-off with 10 nH loop inductance, inductive overshoot reaches V = L*dI/dt = 10 nH * 100 A / 10 ns = 100 V, exceeding 80 V rating.
Use at least 2 oz copper on top and bottom layers for the drain pad area, with thermal vias (0.3 mm diameter, 1.0 mm pitch) connecting to inner copper planes. Avoid placing signal traces under the device to maximize continuous copper. For >5 W continuous dissipation, add a small aluminum heatsink (e.g., 10 mm x 10 mm x 5 mm) with thermal interface material on the top exposed pad.
