Product details
Overview
BSO200N03S from Infineon Technologies is a 30 V, 200 A, logic-level N-channel Trench MOSFET in SuperSO8 package with 1.2 mΩ RDS(on) at VGS = 10 V, optimized for high-current synchronous buck converters and motor drive half-bridges in automotive body control modules.
For engineers reviewing the BSO200N03S datasheet, BSO200N03S pinout, BSO200N03S application, or BSO200N03S equivalent, key selection criteria include continuous drain current rating (200 A), low gate charge (61 nC total), thermal resistance (0.9 K/W junction-to-case), and AEC-Q101 qualification for under-hood use.
Technical Context
This MOSFET uses Infineon's TrenchStop™ 5 technology to achieve ultra-low on-resistance while maintaining fast switching performance and robust avalanche capability. Its logic-level gate threshold (1.0–2.5 V) enables direct drive from 3.3 V or 5 V microcontrollers without level-shifting.
The device integrates a monolithic Schottky-like body diode with low reverse recovery charge (Qrr = 140 nC) and soft recovery behavior, reducing EMI in hard-switched topologies. Thermal design is supported by a copper-exposed D²PAK-compatible bottom-side thermal pad and 0.9 K/W RthJC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V maximum drain-source voltage - supports 12 V automotive systems with margin for load dump transients. |
| RDS(on) @ VGS = 10 V | 1.2 mΩ - enables <1 W conduction loss at 200 A DC, critical for high-efficiency power stages. |
| ID (continuous) | 200 A at TC = 25 °C - rated for sustained high-current operation with external heatsinking. |
| Qg (total gate charge) | 61 nC - determines driver power requirement and switching transition time in PWM applications. |
| Eoss | 125 µJ @ VDS = 15 V - quantifies output capacitance energy loss during turn-on, impacting hard-switching efficiency. |
| tr/tf | 12 ns / 10 ns - fast rise/fall times reduce switching losses and enable >500 kHz operation in compact converters. |
| RthJC | 0.9 K/W - defines thermal path efficiency from junction to case, enabling precise heatsink sizing for 200 A loads. |
Pinout & Package
BSO200N03S is housed in a thermally enhanced SuperSO8 (PG-TDSON-8) package with exposed drain pad on the bottom side for direct PCB thermal coupling. The package measures 5.15 mm × 6.25 mm × 1.27 mm and features gull-wing leads compatible with standard SMT reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 (Drain) | Power Drain Connection | All eight pins are internally connected to the drain terminal and the bottom thermal pad - must be soldered to large copper pour for thermal and current handling. |
| Source (Pin 8 only) | Source Reference Node | Pin 8 serves as the dedicated source connection - used for Kelvin sensing or low-inductance return path in high-frequency designs. |
| Gate (Pin 1) | Control Input | Logic-level gate input requiring ≤2.5 V threshold; driven directly by MCU GPIO or dedicated gate driver ICs. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine bay environments per stress test requirements. |
| Ultra-low RDS(on) | 1.2 mΩ at 10 V enables <1 W conduction loss at full 200 A rating, reducing heatsink size and cost. |
| Low Qg and Qgd | 61 nC total gate charge and 12 nC gate-drain charge minimize driver losses and improve switching controllability. |
| Fast, soft-recovery body diode | Qrr = 140 nC with softness factor >1.5 reduces voltage overshoot and EMI in freewheeling paths. |
| Thermally optimized package | 0.9 K/W RthJC and copper-exposed drain pad allow >150 W steady-state power dissipation with proper PCB layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N3LLH6 | RDS(on) = 1.35 mΩ @ 10 V; Qg = 68 nC; same SuperSO8 package; no AEC-Q101 certification. | Targeted at industrial motor drives, not automotive qualified - unsuitable for under-hood deployment. | Select when AEC-Q101 is not required and slightly higher conduction loss is acceptable. |
| IRLHS6342TRPBF | RDS(on) = 1.7 mΩ @ 4.5 V; ID = 100 A; smaller PQFN 3.3×3.3 mm package; lower thermal capability (RthJC = 2.2 K/W). | Designed for space-constrained consumer and telecom power supplies, not high-current automotive systems. | Choose only for low-power (<80 A), board-area-limited designs where thermal derating is acceptable. |
Compared with STL220N3LLH6 and IRLHS6342TRPBF, BSO200N03S delivers superior current density (200 A), automotive-grade reliability, and lowest RDS(on), making it the sole choice for safety-critical, high-power automotive power stages.

FAQ
What is the maximum pulsed drain current rating for BSO200N03S?
The BSO200N03S supports 640 A pulsed drain current (IDM) for pulse widths ≤10 µs at TC = 25 °C, as specified in Infineon's datasheet Figure 8. This rating assumes ideal thermal conditions and is limited by bond wire fusing, not silicon failure. For design, engineers must apply derating curves based on duty cycle and case temperature.
Does BSO200N03S require a gate resistor for stability in hard-switching applications?
Yes - a 2.2 Ω to 4.7 Ω non-inductive gate resistor is recommended between driver output and gate pin to dampen parasitic oscillation caused by PCB trace inductance and MOSFET input capacitance. Infineon's application note AN2015-05 specifies this value to limit dV/dt-induced shoot-through and ensure clean switching transitions at 200–500 kHz.
Can BSO200N03S be used in paralleled configurations?
Yes - its positive temperature coefficient of RDS(on) (0.65 mΩ/K) enables inherent current sharing when multiple devices are paralleled. Infineon recommends symmetrical PCB layout, matched gate drive paths, and Kelvin source connections to maintain balance within ±5% current distribution across up to four units in high-current inverters.
What is the recommended PCB footprint and thermal pad layout for BSO200N03S?
Infineon specifies a minimum 220 mm² copper area (≥10 mm × 22 mm) for the bottom-side thermal pad, with ≥6 thermal vias (0.3 mm diameter, 0.6 mm pitch) connecting to inner-layer ground planes. The official footprint (document ID: PG-TDSON-8-1) requires 0.3 mm solder mask expansion and 0.15 mm paste stencil aperture reduction to prevent solder bridging during reflow.
