BSP296NH6327XTSA1 Overview
An N-Channel enhancement-mode MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled semiconductor switch that conducts current between drain and source when the gate-source voltage exceeds the threshold. Small-signal/small-power MOSFETs sit in the discrete-semiconductor hierarchy below power MOSFETs and are typically used for loads up to a few amps, where their low gate charge and fast switching edges enable efficient DC-DC conversion, level shifting, and high-side/low-side switching in compact surface-mount designs.
Key electrical features include a 100 V drain-source breakdown rating, 1.2 A continuous drain current at 25 Β°C ambient, and a maximum on-resistance of 600 mΞ©. The device dissipates up to 1.8 W at Ta=25 Β°C with a standard 1 oz copper pad, and its SOT-223 footprint provides a usable drain tab for thermal relief. The gate is standard threshold-level driven, allowing direct interface with 5 V microcontrollers and standard logic-level gate drivers without pre-driver circuitry.
The BSP296N die uses an optimized trench cell geometry that minimizes RDS(on) * gate-charge figure-of-merit, balancing conduction loss and switching loss for sub-2 A loads. Its AEC-Q101 automotive qualification covers temperature range, humidity bias, and power-cycling stress, making it suitable for under-hood and chassis applications as well as industrial 24 V bus switching where 100 V drain headroom protects against inductive transients.
Typical applications include relay and solenoid replacement in automotive body modules, DC-DC converter high-side switches, motor-driver bridges for small fans and pumps, load switches in industrial 24 V PLC systems, and LED driver stages. The 100 V rating also supports offline-derived auxiliary rails up to 60 V continuous and provides ample margin for flyback converter primary switching.
When designing with this device, ensure the gate is driven fully enhanced (10 V recommended for lowest RDS(on)) and use a pull-down resistor to prevent unwanted turn-on during MCU reset. A gate-series resistor of 10-100 Ξ© controls ringing and limits inrush dV/dt. For thermal reliability at 1 A continuous load, allocate at least 100 mmΒ² of 1 oz copper on the drain tab.

Typical Applications
BSP296NH6327XTSA1 is suitable for 7 applications: Automotive Relay & Solenoid Replacement, Industrial 24V Load Switch, DC-DC Converter High-Side Switch, Small Motor Driver (Fans & Pumps), LED Driver Stage, Battery Protection & Power Path Switching, Audio Amplifier Output Stage (Class-D).
Automotive Relay & Solenoid Replacement
The BSP296NH6327XTSA1's 1.2 A continuous drain rating and 100 V VDS directly replace electromechanical relays in body-control modules, where solid-state switching eliminates coil current draw, contact bounce, and audible click. Placed as a low-side switch on the load's low side with the source tied to chassis ground, it switches solenoids, valves, and small motors at 10-100 kHz PWM. AEC-Q101 qualification supports under-hood and chassis deployment. Add a flyback diode or TVS clamp across inductive loads to clamp VDS within the 100 V rating during turn-off transients.
Recommended
Industrial 24V Load Switch
In industrial PLC and sensor systems, the BSP296NH6327XTSA1 serves as a high-side or low-side switch on 24 V DC buses, providing 1.2 A continuous current capability for actuators, solenoid valves, and relay coils. Its 100 V VDS rating gives 4x transient headroom over the 24 V nominal rail, surviving load-dump events and inductive kickback. Gate drive directly from a 5 V microcontroller GPIO via a 100 Ξ© gate resistor keeps the BOM minimal. Mount the drain tab to at least 100 mmΒ² of 1 oz copper for thermal reliability at sustained 1 A loads.
Recommended
DC-DC Converter High-Side Switch
The BSP296NH6327XTSA1 functions as the synchronous-rectifier or main switch in sub-2 A buck and boost converters operating from 24-60 V input rails. Its 100 V VDS rating supports wide-Vin telecom and industrial bus voltages, while the 600 mΞ© RDS(on) keeps conduction loss low at 1 A load. Low gate charge enables switching frequencies up to 500 kHz for compact inductor selection. Pair with a dedicated gate driver like the IRS2110SPBF for fastest turn-on/turn-off transitions and lowest switching loss.
Recommended
Small Motor Driver (Fans & Pumps)
H-bridge and half-bridge configurations using two BSP296NH6327XTSA1 devices drive small DC fans, water pumps, and blower motors in HVAC and appliance applications. Each MOSFET's 1.2 A rating handles motors up to ~10 W mechanical output at 12-24 V supply. The 100 V rating provides robustness against back-EMF spikes from motor inductance during PWM commutation. Use complementary P-channel devices from Infineon's BSP-series for the high-side leg to simplify gate drive from 5 V logic.
Recommended
LED Driver Stage
As a constant-current linear regulator switch or PWM dimmer for LED strings, the BSP296NH6327XTSA1 handles strings up to 1.2 A from 24-48 V supply rails. The 100 V VDS rating supports long LED chains without cascaded lower-voltage MOSFETs. Used in architectural, automotive interior, and signage lighting, it enables PWM dimming at >1 kHz without audible noise. The SOT-223 footprint is small enough for linear-LED strips but robust enough thermally when the drain tab is properly soldered to copper pour.
Recommended
Battery Protection & Power Path Switching
The BSP296NH6327XTSA1 serves as the power-path switch or discharge MOSFET in low-power battery management systems for 12-48 V battery packs, including e-bikes, power tools, and UPS modules. Its 100 V VDS rating covers multi-cell battery stacks up to 10S Li-ion, and its low RDS(on) minimizes conduction loss during discharge. The SOT-223 footprint allows compact protection PCBs. Pair with a battery monitor IC for overcurrent and overvoltage protection with sub-millisecond fault response.
Recommended
Audio Amplifier Output Stage (Class-D)
In sub-2 W Class-D audio amplifiers and headphone drivers, the BSP296NH6327XTSA1 functions as the half-bridge output switch on 12-24 V supplies. Its low gate charge and fast switching edges minimize switching loss in 250-500 kHz PWM loops, while its 100 V VDS rating provides margin against speaker back-EMF. The SOT-223 thermal pad handles continuous 1 W dissipation when properly soldered to copper pour. Complementary N-channel devices can be paired for full-bridge Class-D output stages.

Key Differentiators
- AEC-Q101 automotive qualification on the base die (vs Generic industrial-only N-channel SOT-223 MOSFETs)
- Higher VDS headroom (100 V) for industrial 24 V bus applications (vs NTDV5804N (also 100 V))
- Same-brand Tape & Reel variants (H6327 vs H6433) for production flexibility (vs Single-reel-only competitors)
Design Notes
Estimated: at continuous ID=1.2 A with RDS(on)=600 mOhm, conduction loss is ~0.86 W. With a SOT-223 ΞΈJA of approximately 50 C/W on minimum copper pad (per JEDEC EIA/JESD51), junction temperature rise above ambient would be ~43 C. For 1 A continuous load at 25 C ambient, allocate at least 100 mmΒ² of 1 oz copper pour on the drain tab to keep Tj below 100 C. Forced airflow is required for sustained operation at 1.2 A in enclosed housings.
Solder the drain tab (Pin 4) to a continuous copper pour that extends at least 5 mm beyond the package body on all sides. Use thermal vias (0.3 mm drill, 1 mm pitch) to connect the top pour to internal ground or floating copper planes for improved heat spreading. Per IPC-2222, the drain tab is electrically connected to Pin 2 (Drain), so do NOT connect the pour to circuit ground if used as a low-side switch (would short drain to source).
Always include a 10 kΞ© gate-to-source pull-down resistor to prevent floating-gate turn-on during MCU reset or power-up transients. Without it, the gate can charge through the gate-drain capacitance (Miller effect) when the drain voltage rises rapidly, causing partial turn-on and possible shoot-through in half-bridge configurations. Also add a TVS diode across inductive loads to clamp VDS within the 100 V maximum rating during turn-off transients.
Keep the gate-drive loop (gate-series resistor β MOSFET gate β source) as small as possible to minimize parasitic inductance and ringing. For switching applications above 100 kHz, use a 10-100 Ξ© gate resistor to dampen LC ringing between gate capacitance and trace inductance. Route the high-current drain and source paths with wide traces (β₯0.5 mm per amp) to minimize conduction loss and thermal stress.
