Product details
Overview
BUK6207-55C,118 from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS FET in DPAK (SOT428) package, designed for automotive power switching with 55 V VDS, 90 A continuous drain current at Tmb = 25 °C, 6.6 mΩ typical RDS(on) at VGS = 10 V and Tj = 25 °C, and 175 °C maximum junction temperature - deployed in electric power steering and start-stop micro-hybrid systems.
For engineers reviewing the BUK6207-55C,118 datasheet, BUK6207-55C,118 pinout, BUK6207-55C,118 application, or BUK6207-55C,118 equivalent, this part supports logic-level and standard gate drive compatibility, delivers high avalanche ruggedness (143 mJ unclamped), and enables thermally demanding 12 V/24 V automotive load control where low conduction loss and robust thermal performance are critical.
Technical Context
This intermediate-level gate drive MOSFET uses Nexperia's TrenchMOS technology to achieve low RDS(on) while maintaining stable threshold voltage (VGS(th) = 1.8–2.8 V at 25 °C) and tight dynamic parameter control - including 82 nC total gate charge at VGS = 10 V and 44 ns rise time under standard test conditions.
Its thermal design centers on a low 0.95 K/W junction-to-mounting-base resistance and integrated mounting base (connected to drain), enabling direct heatsink attachment for high-power automotive loads; the device sustains repetitive avalanche operation up to 170 °C average junction temperature per IEC 60134 limiting values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V - Maximum drain-source blocking voltage; defines safe operating range in 24 V automotive systems with transient overvoltage margin. |
| ID (continuous) | 90 A at Tmb = 25 °C - Package-limited current handling capacity; requires thermal management above 25 °C mounting base temperature. |
| RDS(on) | 6.6 mΩ typ @ VGS = 10 V, ID = 25 A, Tj = 25 °C - Low conduction loss enabling <1 W dissipation at 40 A, critical for efficiency in motor/solenoid drivers. |
| EAS | 143 mJ unclamped - Non-repetitive avalanche energy rating; supports inductive load switching without external snubbers in solenoid and transmission control. |
| Tj max | 175 °C - Maximum junction temperature; allows operation in engine bay environments with minimal derating versus industrial-grade MOSFETs. |
| QG(tot) | 82 nC @ VGS = 10 V - Gate drive energy requirement; determines driver IC selection and switching loss in PWM-controlled 12 V/24 V loads. |
| Rth(j-mb) | 0.95 K/W - Junction-to-mounting-base thermal resistance; enables direct thermal path to heatsink, reducing thermal impedance by >50% vs. PCB-only cooling. |
Pinout & Package
Package: DPAK (SOT428), plastic single-ended surface-mounted package with 3 leads (one lead cropped); mounting base (mb) electrically connected to drain and thermally coupled to heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal accepting logic-level (≥4.5 V) or standard (10 V) gate drive; threshold voltage 1.8–2.8 V ensures reliable turn-on with automotive MCU GPIOs. |
| 2 (D) | Drain | Main high-side or low-side power path terminal; internally bonded to mounting base for simultaneous electrical connection and thermal conduction. |
| 3 (S) | Source | Reference node for gate drive and current sensing; source inductance 7.5 nH minimizes ringing during fast switching in motor control. |
| mb | Mounting Base | Electrically tied to drain; provides primary thermal interface to heatsink - not a signal pin but essential for power dissipation up to 158 W at Tmb = 25 °C. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive reliability including temperature cycling, humidity testing, and mechanical shock - required for safety-critical EPS and transmission modules. |
| Logic- and standard-level gate drive compatibility | VGS(th) range (1.8–2.8 V) and low QG enable direct drive from 3.3 V/5 V MCUs and compatibility with legacy 10 V gate drivers without level-shifting. |
| 175 °C junction temperature rating | Enables uninterrupted operation in under-hood environments (e.g., near engine blocks or exhaust manifolds) without thermal shutdown or parameter drift. |
| Integrated source-drain diode | VSD = 0.85–1.2 V @ IS = 25 A supports freewheeling in inductive loads; trr = 48 ns limits reverse recovery losses in PWM motor drives. |
| High avalanche ruggedness | 143 mJ unclamped EAS withstands inductive kickback from solenoids and brushed DC motors without external protection components. |
Applications
| Electric Power Steering (EPS) | Start-Stop Micro-Hybrid Systems |

| Transmission Control Solenoids | LED Headlamp Dimming Drivers |
|
Use Scenario: Precision current regulation for electro-hydraulic shift solenoids requiring fast, repeatable actuation timing. IC Role / Device Role / Timing Role: PWM-controlled power switch delivering 2–5 A at 12 V with <50 ns switching transitions to meet ISO 16750-2 transient immunity requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N5LF5AG | 60 V VDS, 220 A ID, 2.2 mΩ RDS(on) - higher current, lower RDS(on), but larger TO-263 package and 10 V gate drive only. | Targeted at high-power traction inverters; less suitable for space-constrained EPS modules due to footprint and gate drive mismatch. | Select when >120 A continuous current and <3 mΩ conduction loss are required; verify gate driver compatibility and PCB thermal layout for TO-263. |
| IRF1405ZPBF | 55 V VDS, 169 A ID, 5.3 mΩ RDS(on) - non-AEC-Q101, TO-220 package, no mounting base, higher thermal resistance (1.2 K/W). | Intended for industrial motor drives; lacks automotive qualification and thermal performance for under-hood deployment. | Acceptable only for non-automotive prototypes or cost-sensitive industrial controls where AEC-Q101 compliance and 175 °C operation are not required. |
Compared with STL220N5LF5AG and IRF1405ZPBF, BUK6207-55C,118 uniquely balances AEC-Q101 compliance, DPAK thermal efficiency, logic-level gate drive, and 55 V/90 A capability - making it optimal for production automotive modules where qualification, size, and thermal integration are co-constrained.

FAQ
Is BUK6207-55C,118 pin-compatible with other DPAK-packaged N-channel MOSFETs?
Yes - it uses the standard SOT428 (DPAK) outline with G-D-S pinning (pin 1 = gate, pin 2 = drain, pin 3 = source) and mounting base tied to drain. Mechanical compatibility is confirmed per JEDEC SC-63 and IEC 60134 outlines, though electrical parameters (RDS(on), QG, VGS(th)) differ across variants and require circuit validation.
What is the maximum allowable gate-source voltage for continuous operation?
The absolute maximum DC VGS is ±16 V per datasheet Table 4. Operation above ±16 V risks permanent gate oxide damage. For reliable long-term use, gate drive should be limited to 10 V to avoid accelerated degradation while ensuring full enhancement of the 6.6 mΩ RDS(on) spec.
Can BUK6207-55C,118 be used in high-frequency PWM applications above 100 kHz?
It supports switching up to ~200 kHz based on its 44 ns rise time and 78 ns fall time, but practical frequency limits depend on gate drive strength and thermal management. At >100 kHz, switching losses dominate; use with ≥2 A peak gate driver and minimize trace inductance to maintain clean edges and avoid oscillation.
Does the mounting base require electrical isolation from the heatsink?
No - the mounting base is electrically connected to the drain terminal, so heatsink isolation is mandatory unless the heatsink is referenced to drain potential. Use insulating thermal pads or ceramic washers rated for ≥55 V working voltage and 175 °C continuous operation to prevent short circuits.
