Product details
Overview
BUK7M33-60EX from Nexperia is an AEC-Q101-qualified N-channel standard-level MOSFET in LFPAK33 (SOT1210) package, rated for 60 V VDS, 33 mΩ RDS(on) at 10 V VGS and 25 °C, 175 °C junction temperature, and repetitive avalanche capability-designed for automotive load switching in 12 V systems including transmission control and solenoid drivers.
For engineers reviewing the BUK7M33-60EX datasheet, BUK7M33-60EX pinout, BUK7M33-60EX application, or BUK7M33-60EX equivalent, this page delivers verified electrical specs, thermal performance data, gate charge characteristics, automotive qualification context, and real-world use cases in thermally demanding vehicle subsystems.
Technical Context
This device uses TrenchMOS technology to achieve low on-resistance with true standard-level gate drive (VGS(th) > 1 V at 175 °C), enabling direct interface with 5 V microcontrollers without level-shifting. Its LFPAK33 package provides 2.77 K/W typical Rth(j-mb), supporting high-power density mounting on PCB copper planes.
The MOSFET features fully characterized dynamic parameters-including 3.8 nC QGD, 10.9 nC QG(tot), and 472 pF Ciss-and is specified for unclamped inductive switching with 10.3 mJ single-pulse avalanche energy at 24 A, making it suitable for robust motor and lamp control transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V maximum drain-source voltage - supports full 12 V automotive battery transient margin (up to ISO 7637-2 Pulse 5a). |
| RDS(on) | 27–33 mΩ at VGS = 10 V, ID = 5 A, Tj = 25 °C - enables <1.5 W conduction loss at 20 A continuous current with proper heatsinking. |
| ID | 24 A continuous drain current at Tmb = 25 °C - validated for sustained operation in engine bay environments with board-level thermal management. |
| Ptot | 44 W total power dissipation at Tmb = 25 °C - defines maximum steady-state power handling before thermal derating begins. |
| QGD | 3.8 nC gate-drain charge - directly impacts switching speed and Miller-induced turn-off delay in hard-switched inductive loads. |
| Tj max | 175 °C maximum junction temperature - ensures reliable operation under under-hood thermal stress without derating gate threshold. |
| EAS | 10.3 mJ non-repetitive avalanche energy - quantifies ruggedness against inductive kickback in solenoid and motor commutation. |
Pinout & Package
LFPAK33 (SOT1210) is a surface-mount, single-ended power package with exposed mounting base connected to drain, optimized for low-inductance, high-current PCB routing and efficient thermal transfer to copper pour or heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source (S) | Three parallel source terminals reduce bond-wire inductance and improve current sharing in high-di/dt applications. |
| 4 | Gate (G) | Single gate input with 10.9 nC total gate charge - compatible with standard 5 V logic-level drivers and MCU GPIOs. |
| Mounting Base (mb) | Drain (D) | Exposed copper pad electrically connected to drain - serves as primary thermal path and high-current return node. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability across temperature, humidity, and mechanical stress per JESD47. |
| Repetitive avalanche rated | Rated for repeated inductive energy clamping without degradation - critical for transmission valve and fuel injector drivers. |
| 175 °C junction rating | Enables operation in under-hood locations without gate-threshold collapse or accelerated wear-out mechanisms. |
| Standard-level VGS(th) | VGS(th) > 1 V at 175 °C - guarantees turn-on margin with 5 V controllers even at peak temperature. |
| Low Rth(j-mb) | 2.77 K/W typical thermal resistance - allows >20 W dissipation with ≤55 °C temperature rise above mounting base. |
Applications
| Automotive Transmission Control | Engine Bay Solenoid Driver |
|---|---|
|
Use Scenario: High-duty-cycle PWM control of hydraulic pressure solenoids in automatic transmission valve bodies. IC Role / Device Role / Timing Role: Power switch regulating 12 V supply to solenoid coils with fast turn-on/turn-off timing (ns-scale td(on)/td(off)). Use Value: 3.8 nC QGD and 4.4 ns tr enable precise duty cycle control up to 20 kHz while limiting switching losses below 0.3 W at 15 A. |
Use Scenario: On/off switching of fuel injector or EGR valve solenoids in high-temperature engine compartments. IC Role / Device Role / Timing Role: Robust low-side switch handling 24 A peak pulsed current with repetitive avalanche tolerance. Use Value: 10.3 mJ EAS and 175 °C Tj rating ensure survival during repeated inductive flyback events without external snubbers. |
| 12 V Automotive Lighting | Electric Power Steering (EPS) Auxiliary Load |
|
Use Scenario: Dimmable headlamp or daytime running light (DRL) control using PWM-based current regulation. IC Role / Device Role / Timing Role: Low-RDS(on) power FET operating in linear or switching mode for LED current shaping. Use Value: 27 mΩ RDS(on) minimizes conduction loss (<0.6 W at 5 A), reducing thermal load on compact headlamp PCBs. |
Use Scenario: Switching auxiliary 12 V loads (e.g., cooling fan, sensor bias) in EPS control modules subject to vibration and thermal cycling. IC Role / Device Role / Timing Role: AEC-Q101-compliant discrete switch ensuring functional safety compliance for ASIL-B subsystems. Use Value: Q101 qualification and 2.77 K/W Rth(j-mb) support long-term reliability in sealed, convection-limited EPS enclosures. |
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, 2.2 mΩ RDS(on), 220 A ID, PowerFLAT 5x6 package - lower RDS(on) but higher gate charge (42 nC QG) and no AEC-Q101 documentation in public datasheet. | Targeted at high-current EPS main motor drives, not solenoid/valve control where fast switching and low QGD matter more than ultra-low RDS(on). | Select when system-level thermal budget allows larger package and gate driver can handle 4× higher QG. |
| IRF3205PBF | 55 V, 8 mΩ RDS(on), TO-220 package - lacks AEC-Q101 qualification, 175 °C rating, and repetitive avalanche spec; Rth(j-c) ≈ 1.5 K/W (vs. 2.77 K/W j-mb). | Suitable only for non-automotive industrial or consumer 12 V switching where qualification and thermal performance are secondary. | Use only in cost-sensitive, non-automotive designs with adequate heatsinking and no requirement for automotive reliability validation. |
Compared with STL220N6F7 and IRF3205PBF, BUK7M33-60EX uniquely balances AEC-Q101 compliance, 3.8 nC QGD for fast switching, 175 °C operation, and LFPAK33's superior thermal efficiency-making it the optimal choice for space-constrained, thermally aggressive automotive solenoid and transmission control nodes.

FAQ
Is BUK7M33-60EX pin-compatible with other LFPAK33 MOSFETs?
Yes-BUK7M33-60EX uses the standardized SOT1210 footprint with 1–3 as source, 4 as gate, and mounting base as drain. All Nexperia LFPAK33 N-channel MOSFETs share identical pinout and land pattern, enabling drop-in replacement within same voltage/current class, provided gate drive and thermal design accommodate RDS(on) and QG differences.
What is the maximum continuous drain current at 100 °C mounting base temperature?
Per Figure 2 in the datasheet, the continuous drain current is 17 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 used with PCB copper area ≥ 200 mm² for reliable operation.
Does BUK7M33-60EX require a gate resistor for automotive PWM applications?
Yes-a series gate resistor (typically 5–10 Ω) is recommended to damp ringing and control dV/dt during switching, especially in noisy 12 V automotive environments. The 3.8 nC QGD and 10.9 nC QG(tot) make it sensitive to parasitic oscillation without controlled gate drive impedance.
Can BUK7M33-60EX replace BUZ70 in existing designs?
No-BUZ70 is a TO-220 packaged 50 V MOSFET with ~100 mΩ RDS(on) and no AEC-Q101 rating. While both are N-channel switches, BUK7M33-60EX offers 3× lower RDS(on), automotive qualification, LFPAK33 thermal advantages, and different pinout-requiring PCB layout and thermal redesign, not direct substitution.
