Product details
Overview
BUK7M67-60EX from Nexperia is an AEC-Q101 qualified N-channel standard-level MOSFET in LFPAK33 (SOT1210) package, rated for 60 V VDS, 67 mΩ RDS(on) at 10 V VGS and 25 °C, and 175 °C junction operation-designed for automotive load switching including transmission control, lamp drivers, and solenoid interfaces.
For engineers reviewing the BUK7M67-60EX datasheet, BUK7M67-60EX pinout, BUK7M67-60EX application, or BUK7M67-60EX equivalent, this device requires attention to its true standard-level gate threshold (>1 V at 175 °C), repetitive avalanche rating, and mounting-base thermal resistance (4.27 K/W) when evaluating for thermally constrained 12 V automotive power stages.
Technical Context
This MOSFET uses TrenchMOS technology and features a monolithic structure with integrated source-drain diode, enabling robust unclamped inductive switching. Its gate threshold voltage remains functional up to 175 °C, supporting operation in engine bay environments without gate drive derating.
The LFPAK33 package provides low-inductance, high-current source connections via three parallel source pins and a drain-connected mounting base, delivering 31 W total power dissipation at Tmb = 25 °C and supporting peak drain current of 58 A in pulsed conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum drain-source blocking voltage compatible with 12 V automotive battery systems with load dump transients. |
| RDS(on) | 67 mΩ (typ. 54 mΩ) at VGS = 10 V, ID = 5 A, Tj = 25 °C - Enables <1 W conduction loss at 12 A continuous drain current under nominal conditions. |
| ID | 14 A continuous at Tmb = 25 °C - Sustains high-current loads such as HVAC blower motors or headlamp drivers without external heatsinking. |
| EAS | 4 mJ non-repetitive avalanche energy - Supports reliable operation in inductive load switching without external snubbers in compact automotive modules. |
| Rth(j-mb) | 4.27 K/W - Enables direct thermal coupling to PCB copper or metal-core substrates, reducing thermal path complexity in space-constrained ECUs. |
| QGD | 2.5 nC - Low gate-drain charge minimizes Miller-induced turn-off delay and improves switching controllability in PWM-driven solenoid valves. |
| VGS(th) | >1 V at Tj = 175 °C - Ensures gate turn-on margin remains intact under extreme under-hood temperatures without requiring elevated gate drive. |
Pinout & Package
LFPAK33 (SOT1210) is a surface-mount plastic package with exposed drain mounting base, optimized for high-power density and low thermal resistance. It features 4 terminals plus mounting base: three source pins (pins 1–3), one gate pin (pin 4), and drain connected to the metal mounting base (mb).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source | Three parallel low-inductance source connections reduce common-source inductance and improve switching stability in high-di/dt applications. |
| 4 | Gate | Single gate input with 6.7 nC total gate charge-compatible with standard 3.3 V/5 V logic-level drivers without level-shifting. |
| mb | Drain / Mounting Base | Exposed copper drain pad soldered directly to PCB thermal plane; serves as primary heat extraction path and high-current drain return. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability across temperature cycling, humidity, and mechanical shock per JESD47 requirements. |
| Repetitive avalanche rating | Enables repeated unclamped inductive switching without degradation-critical for transmission solenoid drivers with frequent on/off cycles. |
| 175 °C maximum junction temperature | Permits placement near heat sources (e.g., powertrain ECUs) without thermal derating of current or voltage ratings. |
| Standard-level gate drive | VGS(th) >1 V at 175 °C ensures compatibility with existing 10 V gate drivers while maintaining noise immunity in noisy vehicle electrical systems. |
| Low Rth(j-mb) | 4.27 K/W enables >25 W dissipation on 25 mm² 2-oz copper pad-reducing need for external heatsinks in compact body control modules. |
Applications
| Transmission Solenoid Control | Lamp Driver Module |
|---|---|
|
Use Scenario: High-speed, high-cycle switching of hydraulic solenoids in automatic transmission valve bodies. IC Role / Device Role / Timing Role: Power switch controlling 12 V solenoid coils with 50–200 ms on-time and 10 A peak current. Use Value: Repetitive avalanche capability eliminates need for external flyback diodes; 175 °C rating supports placement inside sealed transmission control units. |
Use Scenario: PWM dimming and on/off control of LED headlamps and daytime running lights in modern lighting modules. IC Role / Device Role / Timing Role: Low-loss, fast-switching load switch operating at 100–500 Hz with <10 ns rise/fall times. Use Value: 67 mΩ RDS(on) limits conduction loss to <1.3 W at 14 A, enabling fanless design; low QGD ensures clean PWM edge integrity. |
| Engine Cooling Fan Driver | Body Control Module Load Switch |
|
Use Scenario: Variable-speed control of brushless DC cooling fans using phase-controlled or PWM-based drive circuits. IC Role / Device Role / Timing Role: High-current half-bridge low-side switch handling 10–15 A continuous, with 58 A pulsed surge tolerance. Use Value: 31 W Ptot at Tmb = 25 °C allows direct PCB mounting on aluminum-backed boards; thermal resistance supports stable operation at 100 °C ambient. |
Use Scenario: Centralized power distribution for door locks, window lifts, and mirror actuators in body control units. IC Role / Device Role / Timing Role: Protected load switch with overcurrent and thermal shutdown coordination via microcontroller GPIO. Use Value: Standard-level gate simplifies interface with 3.3 V/5 V MCUs; three-source-pin layout reduces PCB trace inductance during fault current interruption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | 60 V, 2.2 mΩ RDS(on), PowerFLAT 5x6 package, 175 °C rated, but gate threshold is 2.5–3.5 V (enhanced level). | Requires higher gate drive voltage; better suited for high-efficiency motor drives than solenoid control where low-threshold margin matters. | Select only if lower RDS(on) justifies redesign of gate driver and thermal layout. |
| ON Semiconductor NTMFS4C09NT1G | 60 V, 9.2 mΩ RDS(on), SO-8FL package, 150 °C max junction, no AEC-Q101 certification stated in datasheet. | Lacks automotive qualification and 175 °C rating-unsuitable for under-hood deployment without additional validation. | Acceptable only for non-safety-critical cabin applications with ambient <105 °C and no AEC compliance requirement. |
Compared with STL220N6F7 and NTMFS4C09NT1G, BUK7M67-60EX uniquely balances AEC-Q101 compliance, true standard-level gate behavior at 175 °C, and LFPAK33's superior thermal performance-making it optimal for space- and temperature-constrained automotive power switches where gate drive simplicity and reliability are prioritized over ultra-low RDS(on).

FAQ
Is BUK7M67-60EX pin-compatible with other LFPAK33 MOSFETs?
Yes-BUK7M67-60EX uses the standard LFPAK33 (SOT1210) footprint with identical pin 1–4 assignment and mounting base connection. All Nexperia LFPAK33 N-channel MOSFETs share this mechanical and thermal layout, enabling drop-in replacement within the same voltage and RDS(on) class when thermal and electrical margins permit.
What is the maximum continuous drain current at 100 °C mounting base temperature?
Per Figure 2 in the datasheet, the continuous drain current is 10.2 A at Tmb = 100 °C and VGS ≥ 10 V. This reflects thermal derating due to reduced heat transfer efficiency at elevated board temperatures, and must be verified against actual PCB copper area and airflow in the target application.
Does BUK7M67-60EX require a gate resistor for automotive EMI compliance?
A gate resistor of 5 Ω is used in the datasheet's switching time test conditions (Figure 14), and typical designs use 4.7–10 Ω to balance EMI suppression and switching speed. Lower values increase dV/dt and radiated emissions; higher values slow switching and raise dynamic losses-optimal value depends on layout, load inductance, and CISPR 25 Class 5 requirements.
Can BUK7M67-60EX replace BUK7M100-60E in existing designs?
No-BUK7M100-60E has 100 mΩ RDS(on), while BUK7M67-60EX is 67 mΩ. Substituting the lower-RDS(on) part increases peak current and avalanche stress during inductive turn-off unless gate drive and snubber networks are re-validated. Thermal performance also improves, requiring review of PCB copper and thermal relief.
