Product details
Overview
BUK7K17-60EX from Nexperia is a dual N-channel standard-level MOSFET in LFPAK56D (SOT1205) package, rated for 60 V VDS, 14 mΩ RDS(on) at 10 V VGS and 25 °C, AEC-Q101 qualified, and rated for continuous operation up to 175 °C junction temperature - deployed in automotive transmission control and high-reliability 12 V power switching.
For engineers reviewing the BUK7K17-60EX datasheet, BUK7K17-60EX pinout, BUK7K17-60EX application, or BUK7K17-60EX equivalent, this page delivers verified electrical specs, thermal performance data, dual-FET pin mapping, automotive-grade ruggedness validation, and real-world selection guidance for thermally demanding power stages.
Technical Context
This device integrates two independent trench-based N-channel MOSFETs in a single LFPAK56D package with shared mounting base, enabling compact dual-switch topologies without cross-conduction risk. Its true standard-level gate (VGS(th) > 1 V at 175 °C) ensures reliable turn-on across full automotive temperature range without level-shifting circuitry.
It features repetitive avalanche rating (55 mJ), 2.84 K/W Rth(j-mb), and 164 A peak drain current capability - supporting robust short-circuit handling and high-current pulse operation in solenoid and motor drive circuits where thermal management and transient resilience are critical.
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 margin. |
| RDS(on) | 11.3 mΩ (typ) @ VGS = 10 V, ID = 10 A, Tj = 25 °C - Enables <1.1 W conduction loss at 10 A, reducing heatsink requirements. |
| ID (cont) | 30 A @ Tmb = 25 °C - Continuous current limited by package thermal capacity, not silicon. |
| Tj max | 175 °C - Extended junction temperature rating supports under-hood deployment without derating penalties. |
| QGD | 8.1 nC - Low gate-drain charge enables fast, low-loss switching in PWM-driven loads like fuel injectors. |
| EAS | 55 mJ (non-repetitive) - Avalanche energy rating validated per IEC 60134, supporting inductive kickback survival. |
| Rth(j-mb) | 2.84 K/W - Low junction-to-mounting-base thermal resistance allows direct PCB copper pour cooling for high-power density designs. |
Pinout & Package
LFPAK56D (SOT1205) is a thermally enhanced surface-mount package with exposed metal mounting base, 8 leads, and optimized copper clip construction for low-inductance, high-current routing. It measures 4.7 × 4.45 × 1.3 mm and supports reflow soldering per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | S1 | Source terminal of FET1 - electrically isolated from S2; connects to low-side return path for first switch. |
| 2 | G1 | Gate terminal of FET1 - requires 10 V drive for full enhancement; threshold remains >1 V up to 175 °C. |
| 3 | S2 | Source terminal of FET2 - independent of S1; enables dual half-bridge or dual low-side configurations. |
| 4 | G2 | Gate terminal of FET2 - fully decoupled from G1; supports asynchronous or complementary control. |
| 5, 6 | D2 | Drain terminals of FET2 - internally paralleled pins reduce package inductance and improve current sharing. |
| 7, 8 | D1 | Drain terminals of FET1 - paralleled for lower RDS(on) contribution and higher pulsed current capability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD testing - eliminates need for additional qualification effort. |
| Repetitive avalanche rating | Rated for repeated inductive energy dissipation (not just single-pulse), enabling robust solenoid and relay driver designs. |
| 175 °C continuous operation | Full specification guaranteed up to Tj = 175 °C - avoids thermal shutdown in engine bay or transmission control modules. |
| True standard-level gate | VGS(th) > 1 V at 175 °C ensures logic-level MCU GPIO (e.g., 3.3 V or 5 V) can reliably initiate turn-on without gate boosting. |
| LFPAK56D thermal performance | 2.84 K/W Rth(j-mb) - outperforms SO-8 and Power-SO8 by >30 %, enabling smaller PCB area for same thermal load. |
Applications
| Automotive Transmission Control | Fuel Injector Driver |
|---|---|
|
Use Scenario: High-speed on/off control of hydraulic solenoids in automatic transmission valve bodies under under-hood temperatures up to 150 °C ambient. IC Role / Device Role / Timing Role: Dual low-side switch - one FET drives solenoid coil, second provides redundancy or auxiliary load control with independent gate timing. Use Value: 175 °C rating and 55 mJ avalanche energy ensure uninterrupted operation during load dump transients and thermal soak conditions. |
Use Scenario: Precision PWM-controlled fuel injection in gasoline direct injection (GDI) engines, requiring sub-millisecond switching and high reliability over 10-year service life. IC Role / Device Role / Timing Role: High-current, low-RDS(on) low-side switch - handles peak currents >20 A with minimal voltage drop and thermal rise. Use Value: 11.3 mΩ RDS(on) at 25 °C and 25.3 mΩ at 175 °C maintains consistent pulse width accuracy across full operating range. |
| 12 V Battery-Powered Motor Drive | High-Performance Lamp Control |
|
Use Scenario: Bidirectional DC motor control in automotive HVAC blower or power seat modules using discrete H-bridge topology with external high-side switches. IC Role / Device Role / Timing Role: Dual N-channel low-side switch - each FET controls one leg of the H-bridge, enabling forward/reverse direction and braking via PWM. Use Value: Independent gate terminals (G1/G2) allow precise dead-time control to prevent shoot-through, while low QGD minimizes switching losses at 20 kHz PWM. |
Use Scenario: Dimmable LED headlamp and daytime running light (DRL) modules requiring high-efficiency, flicker-free current regulation in compact form factor. IC Role / Device Role / Timing Role: Constant-current sink - one FET regulates LED string current; second provides backup or parallel current path for higher lumen output. Use Value: 30 A continuous rating and 164 A peak current support multi-string LED arrays without external current-sharing resistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | 60 V, 2.2 mΩ RDS(on) @ 10 V, but only single-channel in PowerFLAT 5x6; no dual-FET integration. | Requires two devices and extra PCB area to match dual functionality; superior RDS(on) benefits only high-current single-switch use cases. | Select when lowest possible conduction loss is prioritized over board space and gate drive simplicity. |
| ON Semiconductor NTMFS5C675NL | 60 V, 5.2 mΩ RDS(on), single-channel SO-8; AEC-Q101 qualified but lacks avalanche rating and 175 °C operation. | Not suitable for thermally aggressive environments or inductive load protection without external clamping. | Select only for cost-sensitive, non-under-hood applications where ambient stays below 105 °C and avalanche stress is absent. |
Compared with STL220N6F7 and NTMFS5C675NL, BUK7K17-60EX uniquely delivers dual-channel integration, 175 °C operation, and validated avalanche ruggedness in a single LFPAK56D footprint - making it optimal for space-constrained, high-reliability automotive power stages where thermal and transient resilience are non-negotiable.

FAQ
Is BUK7K17-60EX pin-compatible with other LFPAK56D dual-MOSFETs?
No - BUK7K17-60EX uses a unique 8-pin LFPAK56D pinout (S1-G1-S2-G2-D2-D2-D1-D1) with paralleled drain pins. It is not pin-compatible with single-channel LFPAK56D devices or alternate dual-MOSFET variants such as BUK9K18-60E, which has different internal connectivity and pin assignment.
What is the maximum safe operating frequency for PWM switching?
Based on measured td(on) = 7.6 ns, tr = 11.1 ns, td(off) = 15.5 ns, and tf = 11 ns, the device supports clean switching up to 500 kHz in hard-switched applications with appropriate gate drive strength (RG(ext) ≤ 5 Ω) and layout optimization to minimize parasitic inductance.
Does BUK7K17-60EX include integrated ESD protection?
Yes - the device incorporates on-chip ESD protection rated to ≥2 kV HBM per AEC-Q101 requirements. This eliminates need for external TVS diodes in most automotive signal paths, though system-level ESD compliance still requires board-level design validation per ISO 10605.
Can both FETs be used in parallel for higher current capacity?
No - the two FETs share no internal thermal or electrical coupling that guarantees matched current sharing. Parallel operation would require external current-sensing and active balancing circuitry; the datasheet specifies independent operation only, with each FET rated for 30 A continuous at Tmb = 25 °C.
