Product details
Overview
BUK7Y8R7-60EX from Nexperia is a standard-level N-channel TrenchMOS power MOSFET in LFPAK56 (SOT669) package, rated for 60 V VDS, 8.7 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C, and qualified to AEC-Q101 for automotive use. It delivers 87 A continuous drain current at Tmb = 25 °C and supports thermally demanding environments up to 175 °C junction temperature - deployed in 12 V automotive motor and solenoid control circuits.
For engineers reviewing the BUK7Y8R7-60EX datasheet, BUK7Y8R7-60EX pinout, BUK7Y8R7-60EX application, or BUK7Y8R7-60EX equivalent, key selection criteria include its true standard-level gate (VGS(th) > 1 V at 175 °C), repetitive avalanche rating, 1.02 K/W Rth(j-mb), and LFPAK56 mounting base thermal interface - critical for high-reliability automotive power switching.
Technical Context
This MOSFET uses TrenchMOS technology to achieve low on-resistance with robust switching performance: QGD = 14 nC and tf = 19 ns enable fast, controlled turn-off in high-frequency PWM loads. Its gate threshold voltage remains functional across full automotive temperature range (–55 °C to 175 °C), with VGS(th) ≥ 1 V even at maximum junction temperature.
The device integrates a source-drain diode with VSD = 0.83 V at IS = 20 A and Tj = 25 °C, and supports unclamped inductive switching via 76.2 mJ non-repetitive avalanche energy (EAS) - enabling robust operation in relay and solenoid drive where back-EMF suppression is essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum drain-source blocking voltage compatible with 12 V automotive systems with load dump transients. |
| RDS(on) | 5.27–8.7 mΩ at VGS = 10 V, ID = 20 A, Tj = 25 °C - Enables <1 W conduction loss at 40 A, reducing heatsink requirements. |
| ID (continuous) | 87 A at Tmb = 25 °C - Supports high-current actuator drivers without parallel devices. |
| Ptot | 147 W at Tmb = 25 °C - High power dissipation capability enabled by low Rth(j-mb) = 1.02 K/W. |
| VGS(th) | ≥1 V at Tj = 175 °C - Ensures reliable gate turn-on using standard 5 V or 3.3 V microcontroller outputs under worst-case thermal stress. |
| EAS | 76.2 mJ (unclamped, single-pulse) - Withstands inductive kickback from 12 V solenoids and motors without external snubbers. |
| QGD | 14 nC - Limits Miller-induced shoot-through risk in half-bridge configurations with moderate gate drive strength. |
Pinout & Package
LFPAK56 (SOT669) is a surface-mount plastic package with exposed mounting base connected to drain, optimized for high thermal conductivity and mechanical robustness in automotive PCBs. The 4-lead configuration provides dual-source terminals for low-inductance current return paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Source | Primary low-side current return path; electrically tied to pins 2 and 3. |
| 2 | Source | Parallel source connection to reduce bond wire inductance and improve current sharing. |
| 3 | Source | Third source terminal enhancing thermal and electrical connection to PCB copper pour. |
| 4 | Gate | Control input requiring ≤20 V absolute max; driven directly by MCU GPIO or dedicated gate driver. |
| Mounting Base (mb) | Drain | Exposed metal pad soldered to PCB thermal pad; carries full drain current and provides primary heat transfer path to board. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per ISO 10605. |
| Repetitive avalanche rated | Rated for repeated inductive switching events without degradation - enables simplified protection in transmission control modules. |
| 175 °C maximum junction temperature | Permits operation in engine bay locations with minimal derating, supporting compact ECU designs. |
| True standard-level gate | VGS(th) > 1 V at 175 °C ensures compatibility with legacy 5 V logic and avoids need for level-shifting circuitry. |
| Low Rth(j-mb) | 1.02 K/W enables direct PCB thermal coupling - eliminates need for bolted heatsinks in many 12 V actuator applications. |
Applications
| Engine Cooling Fan Control | Automatic Transmission Solenoid Driver |
|---|---|
|
Use Scenario: PWM-controlled 12 V brushless cooling fan operating in ambient temperatures up to 125 °C near engine block. IC Role / Device Role / Timing Role: Low-side power switch handling 40–60 A peak currents with 20 kHz switching frequency. Use Value: 8.7 mΩ RDS(on) limits conduction loss to <2 W at 60 A, while 175 °C rating prevents thermal shutdown during sustained high-load conditions. |
Use Scenario: Driving linear solenoids in 8-speed automatic transmission valve body under stop-start cycling. IC Role / Device Role / Timing Role: High-current, high-reliability switch delivering precise current pulses with fast turn-off (tf = 19 ns) to minimize hydraulic lag. Use Value: Repetitive avalanche rating absorbs solenoid back-EMF without clamping diodes, reducing BOM count and PCB area. |
| Electric Power Steering (EPS) Motor Phase Switch | Body Control Module (BCM) Lamp Driver |
|
Use Scenario: Half-bridge phase leg in 12 V EPS motor inverter, subject to vibration, thermal cycling, and EMI. IC Role / Device Role / Timing Role: N-channel high-side or low-side switch with gate drive compatible with standard 5 V isolated drivers. Use Value: QGD = 14 nC and Ciss = 2375–3159 pF support stable commutation at 10–15 kHz without excessive gate drive power. |
Use Scenario: Switching halogen and LED headlamps, fog lamps, and interior lighting in BCM with diagnostic feedback. IC Role / Device Role / Timing Role: Robust low-side driver with integrated current sensing capability via RDS(on) monitoring. Use Value: 87 A continuous rating allows single-device control of multiple lamps; VGS(th) stability at 175 °C ensures fail-safe open-circuit detection during overtemperature events. |
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), PowerFLAT 5x6 package, 175 °C rated, but requires gate drive ≥10 V for full performance. | Lower RDS(on) improves efficiency in high-duty-cycle EPS applications, but higher gate charge (QG = 105 nC) increases driver complexity. | Select when ultra-low conduction loss dominates over switching speed and gate drive simplicity. |
| IRF1404ZPBF | 40 V, 3.8 mΩ RDS(on), TO-220AB package, not AEC-Q101 qualified, 175 °C rated, higher Rth(j-c) = 1.25 K/W. | Limited to 12 V systems without load dump margin; lacks automotive qualification and LFPAK56 thermal interface. | Acceptable only for non-safety-critical aftermarket or industrial 12 V controls where qualification and board-level thermal performance are secondary. |
Compared with STL220N6F7 and IRF1404ZPBF, BUK7Y8R7-60EX uniquely balances AEC-Q101 compliance, standard-level gate drive, low thermal resistance, and proven avalanche ruggedness - making it optimal for production automotive modules where reliability, thermal management, and system-level integration are co-constrained.

FAQ
Is BUK7Y8R7-60EX pin-compatible with other LFPAK56 MOSFETs?
Yes - BUK7Y8R7-60EX uses the standard SOT669 footprint with identical 4-pin layout (pins 1–3 = source, pin 4 = gate, mounting base = drain). Mechanical compatibility is confirmed per Nexperia's package outline drawing sot669_po, enabling drop-in replacement within same thermal pad design rules.
What is the maximum safe operating temperature for PCB layout?
The mounting base must be soldered to a minimum 200 mm² copper thermal pad with ≥4 thermal vias (0.3 mm diameter, filled) to sustain 147 W at Tmb = 25 °C. Under real-world conditions with 70 °C ambient and 2-layer board, derate to ≤65 W to maintain Tj ≤ 150 °C per thermal simulation data in Figure 4.
Does BUK7Y8R7-60EX require a gate resistor for automotive EMI compliance?
Yes - a 5 Ω series gate resistor is recommended (per datasheet Fig. 13 test condition) to limit dV/dt and suppress ringing during 20–100 kHz PWM switching. This value balances EMI reduction against tf degradation (from 19 ns to ~25 ns), preserving solenoid response time while meeting CISPR 25 Class 5 limits.
Can BUK7Y8R7-60EX replace BUZ70 in existing designs?
No - BUZ70 is a TO-220 device with different pinout, thermal path, and 100 V rating. While both are N-channel MOSFETs, BUK7Y8R7-60EX has lower voltage rating (60 V), superior RDS(on), and LFPAK56 packaging. Direct replacement requires PCB redesign, thermal analysis, and validation of avalanche energy margin in the target inductive load.
