Product details
Overview
BUK9217-75B,118 from Nexperia is a logic-level N-channel TrenchMOS FET in DPAK (SOT428) package, designed for automotive-critical 12 V/24 V/42 V power switching. It delivers 64 A continuous drain current at 25 °C mounting base temperature, features 13.4 mΩ RDS(on) at VGS = 10 V and 25 °C, supports gate drive down to 5 V, and is qualified to AEC-Q101 with 185 °C junction rating.
For engineers reviewing the BUK9217-75B,118 datasheet, BUK9217-75B,118 pinout, BUK9217-75B,118 application, or BUK9217-75B,118 equivalent, key selection criteria include logic-level gate compatibility, avalanche ruggedness (147 mJ), thermal resistance (0.95 K/W j-mb), and automotive-grade reliability for high-temperature load control.
Technical Context
This device uses TrenchMOS technology to achieve low on-resistance while maintaining robust switching performance under thermally demanding conditions. Its gate threshold voltage ranges from 1.1–2.0 V at 25 °C and drops to 0.4 V at 185 °C, enabling stable turn-on across full automotive temperature range.
The integrated source-drain diode exhibits 0.85–1.2 V forward voltage at 25 A and 25 °C, with 96 ns reverse recovery time and 138 nC recovered charge - critical for inductive load commutation in motor and solenoid drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 75 V maximum drain-source voltage - supports 42 V automotive systems with margin against transients. |
| ID (continuous) | 64 A at Tmb = 25 °C - enables high-current loads like starter relays or HVAC blowers without external heatsinking. |
| RDS(on) | 13.4 mΩ typ. at VGS = 10 V, 25 °C - reduces conduction loss to ≤1.7 W at 30 A, improving efficiency and thermal headroom. |
| EAS | 147 mJ non-repetitive avalanche energy - sustains unclamped inductive switching events (e.g., solenoid de-energization) without failure. |
| Rth(j-mb) | 0.95 K/W junction-to-mounting-base thermal resistance - allows direct PCB copper pad mounting for effective heat transfer in space-constrained modules. |
| VGS(th) | 1.5 V typ. at 25 °C, 0.4 V min. at 185 °C - ensures reliable turn-on with standard 5 V microcontroller GPIOs across full operating temperature range. |
| QGD | 14 nC gate-drain charge - limits Miller-induced shoot-through risk during high-speed switching in half-bridge configurations. |
Pinout & Package
Package: DPAK (SOT428), plastic single-ended surface-mounted package with 3 leads (lead 2 cropped); mounting base (mb) electrically connected to drain for low-inductance thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Logic-level input controlling channel conduction; requires ≤5 V for full enhancement; low gate charge (35 nC total) enables fast switching with minimal driver effort. |
| 2 (D) | Drain | Main high-side power terminal; internally bonded to mounting base for direct thermal coupling to PCB copper area. |
| 3 (S) | Source | Power return path and reference for gate drive; also serves as cathode of integrated body diode for freewheeling current. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive safety-critical applications including engine control, braking, and ADAS subsystems. |
| 185 °C junction rating | Enables operation in under-hood environments (e.g., near exhaust manifolds or turbochargers) without derating. |
| Low RDS(on) at 5 V drive | 14.4 mΩ typ. at VGS = 5 V and 25 °C - eliminates need for gate boosters in 5 V MCU-based designs. |
| Integrated avalanche ruggedness | 147 mJ EAS - protects against inductive kickback in motor/solenoid circuits without external snubbers. |
| Thermally optimized DPAK | 0.95 K/W Rth(j-mb) - achieves >90% of TO-220 thermal performance in 30% footprint area. |
Applications
| Engine Control Module Loads | Body Control Module Switching |
|---|---|
Use Scenario: Driving fuel injectors, ignition coils, and idle air control valves in ICE powertrain systems. IC Role / Device Role / Timing Role: High-side power switch with precise PWM timing control and fast turn-off (<160 ns total switching time) to meet emission and torque response requirements. Use Value: Low RDS(on) minimizes I²R heating during extended duty cycles; 185 °C rating ensures reliability near hot engine blocks. |
Use Scenario: Controlling headlights, fog lamps, power windows, and seat heaters in vehicle body electronics. IC Role / Device Role / Timing Role: Robust load switch handling inrush currents up to 256 A peak (IDM) and sustaining 64 A continuous loads. Use Value: Avalanche energy rating absorbs lamp filament cold-resistance surges; AEC-Q101 compliance guarantees long-term field reliability. |
| Electric Power Steering (EPS) | Start-Stop System Actuators |
Use Scenario: Managing assist motor phase current and clutch engagement in 12 V EPS modules. IC Role / Device Role / Timing Role: Half-bridge high-side switch with tight gate charge matching (QGD = 14 nC) to minimize cross-conduction risk. Use Value: Fast switching (tr = 102 ns, tf = 58 ns) enables high-frequency PWM for smooth torque delivery; low Coss (290–348 pF) reduces switching losses. |
Use Scenario: Activating starter solenoids and battery disconnect switches during automatic engine restart. IC Role / Device Role / Timing Role: High-current DC switch handling repeated 256 A pulsed loads with <10 µs pulse width. Use Value: Peak current rating (IDM = 256 A) and thermal stability (Tj up to 185 °C) prevent thermal runaway during frequent start-stop cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N4F7AG | 40 V VDS, 220 A ID, 1.4 mΩ RDS(on) - higher current, lower voltage rating. | Optimized for 12 V EV auxiliary systems; unsuitable for 24/42 V truck or commercial vehicle applications. | Select only when system voltage ≤16 V and peak current >150 A is required; verify gate drive compatibility with 4.5 V threshold. |
| IRF3205PBF | 55 V VDS, 110 A ID, 8.0 mΩ RDS(on) - no AEC-Q101 qualification, 175 °C max Tj. | Industrial-grade only; lacks automotive qualification and high-temperature endurance for under-hood use. | Acceptable for non-safety-critical 12 V industrial controls; avoid in automotive ECUs or modules requiring ASIL-compliant components. |
Compared with STL220N4F7AG and IRF3205PBF, BUK9217-75B,118 uniquely balances 75 V rating, AEC-Q101 compliance, 185 °C operation, and logic-level 5 V drive - making it the only viable choice for 24/42 V automotive power switching where qualification and thermal margin are mandatory.

FAQ
Is BUK9217-75B,118 suitable for 42 V stop-start systems?
Yes. Its 75 V VDS rating provides 33% margin above 42 V nominal systems, and its 256 A peak drain current (IDM) handles starter solenoid inrush. The 147 mJ avalanche energy rating protects against load dump transients common in 42 V architectures.
What is the maximum gate-source voltage for safe operation?
The absolute maximum VGS is ±15 V per the datasheet limiting values table. Operation beyond this risks permanent gate oxide damage. For reliable logic-level drive, keep VGS between 4.5 V and 10 V - where RDS(on) remains stable and gate leakage stays below 100 nA.
Can BUK9217-75B,118 be used in parallel configurations?
Yes, but with design precautions. Its positive temperature coefficient for RDS(on) (increasing with Tj) promotes current sharing. Use matched gate resistors (≤10 Ω), symmetrical PCB layout, and individual Kelvin source connections to minimize imbalance and ensure thermal uniformity across paralleled devices.
Does the mounting base require electrical isolation from the PCB?
No - the mounting base is internally connected to the drain terminal, so it must be routed to the same net as the drain. Use a large, unbroken copper pour tied directly to the drain net for optimal thermal dissipation; do not isolate or float the base, as this defeats the 0.95 K/W thermal path design.
