Product details
Overview
BUK7Y15-60EX from Nexperia is an AEC-Q101 qualified N-channel standard-level MOSFET in LFPAK56 (SOT669) package, rated for 60 V VDS, 9.6 mΩ RDS(on) at 10 V VGS and 25 °C, and 175 °C junction temperature - designed for automotive load switching in 12 V systems including solenoid, lamp, and transmission control.
For engineers reviewing the BUK7Y15-60EX datasheet, BUK7Y15-60EX pinout, BUK7Y15-60EX application, or BUK7Y15-60EX equivalent, this device delivers verified repetitive avalanche capability, true standard-level gate drive (VGS(th) > 1 V at 175 °C), and thermally robust LFPAK56 packaging optimized for high-power-density automotive PCB layouts.
Technical Context
This MOSFET uses TrenchMOS technology to achieve low on-resistance with stable threshold voltage across temperature. Its gate-source threshold voltage remains ≥1 V up to 175 °C, enabling reliable turn-on under extreme thermal stress without requiring elevated gate drive.
The device features a mounting base (mb) electrically connected to the drain, enabling direct thermal coupling to heatsinks or copper planes. Its 1.59 K/W junction-to-mounting-base thermal resistance supports high continuous power dissipation (94 W at Tmb = 25 °C) in compact automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum drain-source blocking voltage compatible with 12 V automotive battery transients (e.g., load dump up to 40 V, ISO 7637-2 Pulse 5a). |
| RDS(on) | 9.6 mΩ (typ) at VGS = 10 V, ID = 15 A, Tj = 25 °C - Enables <1.5 W conduction loss at 40 A, critical for thermally constrained engine bay locations. |
| ID | 53 A continuous at Tmb = 25 °C - Supports high-current loads such as starter relays or HVAC blowers without external heatsinking. |
| EAS | 42.6 mJ non-repetitive avalanche energy - Allows safe operation during inductive switching events (e.g., solenoid de-energization) without snubber circuits. |
| Tj(max) | 175 °C - Qualified per AEC-Q101 for under-hood applications where ambient temperatures exceed 125 °C. |
| QGD | 8.3 nC - Low gate-drain charge minimizes Miller-induced switching oscillation and enables fast, clean turn-off in PWM motor control. |
| Rth(j-mb) | 1.59 K/W - Enables efficient heat transfer from die to PCB copper or heatsink, reducing thermal derating in space-constrained modules. |
Pinout & Package
LFPAK56 (SOT669) is a 4-lead surface-mount plastic package with exposed mounting base for enhanced thermal and electrical performance. The base is internally connected to the drain terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source (S) | Three parallel source terminals reduce bond wire inductance and improve current sharing for high di/dt switching. |
| 4 | Gate (G) | Single gate input with standard-level threshold; compatible with 5 V or 3.3 V microcontroller GPIO when used with appropriate drive strength. |
| Mounting Base (mb) | Drain (D) | Exposed copper pad electrically tied to drain - serves as primary thermal path and high-current drain connection; must be soldered to large PCB copper area. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use across -55 °C to +175 °C, including temperature cycling, humidity, and mechanical shock testing. |
| Repetitive avalanche rating | Rated for repeated unclamped inductive switching events - eliminates need for external clamping diodes in solenoid/lamp drivers. |
| True standard-level gate | VGS(th) > 1 V at 175 °C ensures guaranteed turn-on with 5 V logic without gate boosting, simplifying driver design. |
| Thermal robustness | 175 °C max junction temperature and 1.59 K/W Rth(j-mb) enable sustained operation in engine compartment environments. |
| LFPAK56 package | Superior thermal resistance vs. SO-8 (≈3× better), lower parasitic inductance, and higher current capability in same footprint. |
Applications
| Engine Control Solenoid Driver | Automotive Lamp Dimming Module |

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 requires 4.5 V gate drive minimum. | Better conduction efficiency at high current, but less tolerant of marginal gate drive voltage at high temperature. | Select when ultra-low RDS(on) dominates and gate drive is stable ≥4.5 V; verify thermal interface for PowerFLAT vs. LFPAK56. |
| IRF3205PBF | 55 V, 8.0 mΩ RDS(on), TO-220 package, not AEC-Q101 qualified, 175 °C rated. | Lacks automotive qualification and has higher package inductance; unsuitable for safety-critical or vibration-prone locations. | Acceptable only for non-automotive industrial prototypes; avoid in production automotive designs due to missing AEC-Q101 validation. |
Compared with STL220N6F7 and IRF3205PBF, BUK7Y15-60EX uniquely combines AEC-Q101 qualification, true standard-level gate (≥1 V VGS(th) at 175 °C), and LFPAK56's superior thermal performance - making it the only choice for production-grade 12 V automotive switching where reliability, thermal margin, and gate drive simplicity are jointly critical.

FAQ
Is BUK7Y15-60EX suitable for high-frequency PWM motor control above 20 kHz?
Yes - with 17.8 ns turn-off delay and 10.9 ns fall time, plus low 8.3 nC QGD, it supports clean switching up to 50 kHz in brushed DC motor drives. However, gate drive strength ≥1 A peak is recommended to minimize switching losses and ensure full enhancement at high temperature.
What is the maximum allowable PCB copper area for the mounting base to achieve 94 W power dissipation?
To sustain 94 W at Tmb = 25 °C, the mounting base must be soldered to ≥400 mm² of 2 oz (70 µm) copper on an internal layer, with ≥4 thermal vias (0.3 mm diameter, filled) connecting to a solid ground plane - per Nexperia's AN11158 thermal design guidelines for LFPAK56.
Does BUK7Y15-60EX include integrated ESD protection on the gate?
No - the device has no built-in gate ESD protection diode. External 10 kΩ gate resistor and 12 V Zener clamp (e.g., PESD5V0S1BA) between gate and source are required to prevent damage from HBM >2 kV events during handling or system integration.
Can BUK7Y15-60EX replace BUZ70 in existing AEC-Q101-compliant designs?
No - BUZ70 is a TO-220 device with different thermal path, pinout, and 100 V rating. While both are automotive MOSFETs, BUK7Y15-60EX has lower voltage rating (60 V), LFPAK56 footprint, and distinct gate threshold behavior; redesign of layout, thermal interface, and drive circuitry is mandatory.
