Product details
Overview
BUK7M12-60EX from Nexperia is an AEC-Q101-qualified N-channel standard-level MOSFET in LFPAK33 (SOT1210) package, rated for 60 V VDS, 12 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C, and 175 °C junction operation. It delivers 53 A continuous drain current at Tmb = 25 °C and supports ultra-high-performance power switching in automotive 12 V systems including transmission control and solenoid drivers.
For engineers reviewing the BUK7M12-60EX datasheet, BUK7M12-60EX pinout, BUK7M12-60EX application, or BUK7M12-60EX equivalent, key selection criteria include its true standard-level gate (VGS(th) > 1 V at 175 °C), repetitive avalanche rating, 1.82 K/W junction-to-mounting-base thermal resistance, and LFPAK33 package's high-power density with integrated drain mounting base.
Technical Context
This MOSFET employs TrenchMOS technology to achieve low RDS(on) while maintaining robustness under thermally demanding conditions. Its gate threshold voltage remains functional up to 175 °C, enabling reliable turn-on in high-temperature engine bay environments without requiring elevated gate drive.
The device features a monolithic mounting base connected directly to the drain, enabling efficient heat transfer to the PCB copper pour or heatsink. Its 8.5 nC QGD and 24.8 nC QG(tot) support fast, controlled switching in high-frequency PWM applications such as motor phase control and load switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum drain-source blocking voltage; suitable for 12 V automotive battery systems with load dump transients. |
| RDS(on) | 10–12 mΩ @ VGS = 10 V, ID = 15 A, Tj = 25 °C - Low conduction loss enables high-efficiency power switching with minimal thermal rise. |
| ID (continuous) | 53 A @ Tmb = 25 °C - High current capability supports high-power solenoid and motor loads without external heatsinking. |
| Ptot | 75 W @ Tmb = 25 °C - Total power dissipation limit defined at mounting base temperature, not ambient, reflecting real PCB thermal design. |
| Rth(j-mb) | 1.82 K/W - Thermal resistance from junction to mounting base; enables accurate thermal modeling when soldered to 2–4 oz copper pads. |
| QGD | 8.5 nC - Gate-drain charge determines Miller plateau duration; critical for optimizing gate driver sizing and EMI control. |
| VGS(th) | >1 V @ Tj = 175 °C - Ensures guaranteed turn-on with standard 5 V or 12 V logic-level gate drives even at peak under-hood temperatures. |
| EAS | 34.3 mJ - Non-repetitive avalanche energy rating; allows safe operation during inductive load switching without external snubbers. |
Pinout & Package
LFPAK33 (SOT1210) is a surface-mount, single-ended power package with an exposed copper mounting base (drain-connected) and three parallel source terminals for low-inductance, high-current return paths. The package measures 3.40 × 2.45 × 0.90 mm and supports reflow soldering per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source (S) | Three paralleled source terminals reduce package inductance and resistive drop; enable high di/dt switching and low-loss freewheeling. |
| 4 | Gate (G) | Single gate input with 24.8 nC total gate charge; requires ≥1 A peak gate driver for <20 ns switching transitions. |
| Mounting Base (mb) | Drain (D) | Exposed copper pad electrically connected to drain; serves as primary thermal path and high-current drain connection to PCB. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability across temperature, humidity, and mechanical stress cycles-required for engine control, transmission, and body electronics. |
| Repetitive avalanche rated | Withstands repeated inductive energy spikes without degradation; eliminates need for external clamping in solenoid and relay drivers. |
| 175 °C maximum junction temperature | Enables operation in under-hood locations where ambient exceeds 125 °C; reduces derating requirements vs. 150 °C-rated devices. |
| True standard-level gate | VGS(th) > 1 V at 175 °C ensures compatibility with 3.3 V/5 V microcontrollers and automotive logic without level-shifting circuitry. |
| LFPAK33 thermal performance | 1.82 K/W Rth(j-mb) provides ~2× better thermal resistance than comparable SO-8 packages-critical for compact, fanless designs. |
Applications
| Engine Control Module (ECM) Load Switching | Automotive Transmission Solenoid Driver |
|---|---|
Use Scenario: Switching 12 V fuel injector or ignition coil loads in engine control units exposed to under-hood temperatures up to 150 °C. IC Role / Device Role / Timing Role: High-side or low-side power switch controlling pulsed inductive loads with 10–20 kHz PWM frequency. Use Value: Repetitive avalanche rating absorbs flyback energy without snubber components; 175 °C rating prevents thermal shutdown during sustained high-load operation. |
Use Scenario: Driving linear or on/off transmission solenoids in automatic gearboxes where precise current regulation and fault tolerance are critical. IC Role / Device Role / Timing Role: Low-side switching element in closed-loop current-controlled H-bridge or half-bridge configurations. Use Value: 12 mΩ RDS(on) minimizes I²R heating during continuous 2–5 A solenoid hold current; three-source-pin layout reduces parasitic inductance for clean current ramping. |
| 12 V Battery Disconnect Switch | Electric Power Steering (EPS) Motor Phase Control |
Use Scenario: Solid-state replacement for mechanical relays in battery management systems, isolating auxiliary circuits during fault conditions. IC Role / Device Role / Timing Role: High-current, bidirectional (with external diode) or unidirectional isolation switch with fast turn-off for short-circuit protection. Use Value: 211 A peak drain current (IDM) supports high-energy fault clearing; mounting base enables direct thermal coupling to chassis ground for system-level thermal safety. |
Use Scenario: Half-bridge leg in 12 V EPS motor inverters requiring high efficiency, low EMI, and robustness against voltage transients. IC Role / Device Role / Timing Role: Low-side switch in three-phase inverter driving brushed or brushless assist motors up to 1 kW. Use Value: 8.5 nC QGD and 9.7 ns rise time enable <500 ns dead-time control; LFPAK33 package minimizes loop inductance to suppress voltage overshoot during commutation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | 60 V, 1.8 mΩ RDS(on) @ 10 V, but only rated to 150 °C junction; no AEC-Q101 qualification stated in datasheet. | Higher conduction efficiency at room temperature, but unsuitable for sustained 175 °C environments like exhaust proximity modules. | Select only if thermal margin permits lower max Tj and AEC-Q101 is not required by OEM specification. |
| ON Semiconductor NTMFS4C09NT1G | 60 V, 9.5 mΩ RDS(on) @ 10 V, AEC-Q101 qualified, but uses SO-8FL package with higher Rth(j-mb) (2.5 K/W). | Better RDS(on), but reduced thermal performance limits continuous current to ~42 A at Tmb = 25 °C vs. 53 A for BUK7M12-60EX. | Prefer when board space allows SO-8 footprint and lower RDS(on) outweighs thermal constraints. |
Compared with STL220N6F7 and NTMFS4C09NT1G, BUK7M12-60EX uniquely balances AEC-Q101 compliance, 175 °C operation, and LFPAK33's superior thermal resistance-making it optimal for space-constrained, high-temperature automotive power stages where reliability trumps marginal RDS(on) gains.

FAQ
Is BUK7M12-60EX pin-compatible with other LFPAK33 MOSFETs?
Yes-BUK7M12-60EX uses the standardized SOT1210 footprint with identical pin numbering (1–3 = Source, 4 = Gate, mounting base = Drain). All Nexperia LFPAK33 MOSFETs share this mechanical and thermal layout, enabling direct PCB footprint reuse across voltage/current grades.
What is the maximum recommended gate resistor for 100 kHz PWM operation?
For 100 kHz switching with <10 ns rise/fall times, a 2.2 Ω gate resistor is recommended when driven by a 1 A peak gate driver. This value balances switching speed (minimizing overlap loss) against ringing and EMI, given the device's 8.5 nC QGD and 1222 pF Ciss.
Does BUK7M12-60EX require a gate pull-down resistor in automotive applications?
Yes-a 10 kΩ gate-to-source pull-down resistor is strongly recommended to prevent unintended turn-on from ESD, CAN bus noise, or MCU reset states. This ensures fail-safe behavior during power-up, brown-out, or communication faults in safety-critical vehicle subsystems.
Can BUK7M12-60EX be used in synchronous rectification topologies?
No-it is a standard-level MOSFET with VGS(th) > 1 V at 175 °C, not optimized for self-driven synchronous rectification. Its gate threshold is too high and body diode recovery (19.5 ns trr) too slow for efficient 12 V secondary-side rectification; dedicated logic-level or trench Schottky alternatives are preferred.
