Product details
Overview
BUK7K52-60EX from Nexperia is a dual N-channel standard-level MOSFET in LFPAK56D (SOT1205) package, rated 60 V VDS, 45 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 BUK7K52-60EX datasheet, BUK7K52-60EX pinout, BUK7K52-60EX application, or BUK7K52-60EX equivalent, this device supports thermally demanding automotive loads requiring repetitive avalanche capability, true standard-level gate drive (VGS(th) > 1 V at 175 °C), and dual independent channel control in a compact surface-mount footprint.
Technical Context
This dual MOSFET integrates two electrically isolated N-channel TrenchMOS devices in a single LFPAK56D package, sharing no internal connection between channels - each FET features independent source, gate, and drain terminals with matched static and dynamic characteristics. Its 4.68 K/W Rth(j-mb) enables high-power dissipation when mounted on a thermally optimized PCB copper area.
The device operates as a standard-level gate device: VGS(th) ranges from 1.0 V (min at 175 °C) to 4.5 V (max at –55 °C), ensuring reliable turn-on with 5 V–10 V logic-level drivers while maintaining robust noise immunity. Avalanche ruggedness is specified at 11.6 mJ (single-pulse, ID = 15.4 A), supporting inductive load switching without external snubbers in validated designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum drain-source blocking voltage; supports 12 V automotive systems with ≥3× supply margin against transients. |
| RDS(on) | 45 mΩ max at VGS = 10 V, ID = 5 A, Tj = 25 °C - Enables <1.1 W conduction loss at 5 A, critical for thermal management in sealed modules. |
| ID (continuous) | 15.4 A at Tmb = 25 °C - Sustains high-current motor/solenoid drive without forced cooling when properly heatsinked. |
| Tj max | 175 °C - Qualified for under-hood automotive environments; enables operation where ambient exceeds 125 °C with appropriate derating. |
| QGD | 3.5 nC typ - Low gate-drain charge minimizes Miller-induced shoot-through risk in half-bridge configurations. |
| EAS | 11.6 mJ - Repetitive avalanche energy rating allows safe clamping of inductive kickback in transmission valve drivers. |
| Rth(j-mb) | 4.68 K/W - Junction-to-mounting-base thermal resistance enables direct thermal coupling to chassis or copper pour for high-power density layouts. |
Pinout & Package
LFPAK56D (SOT1205) is a thermally enhanced plastic surface-mount package with exposed mounting base, 8 leads, and dual-drain/dual-source layout optimized for low-inductance, high-current routing and efficient heat transfer to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | S1 | Source terminal of FET1 - referenced ground node for first channel; electrically isolated from S2. |
| 2 | G1 | Gate terminal of FET1 - controls turn-on/turn-off of first channel; requires standard-level drive (≥5 V). |
| 3 | S2 | Source terminal of FET2 - independent return path for second channel; not internally connected to S1. |
| 4 | G2 | Gate terminal of FET2 - fully independent control input; enables asynchronous or complementary switching. |
| 5 & 6 | D2 | Drain terminals of FET2 - paralleled pins reduce current density and package inductance for high di/dt loads. |
| 7 & 8 | D1 | Drain terminals of FET1 - paralleled pins provide low-impedance high-current path for first channel. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent N-channel MOSFETs | Two fully isolated FETs in one package - eliminates board space and interconnect inverter/driver pairs for dual-load control. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD - required for powertrain and chassis applications. |
| 175 °C junction rating | Enables placement near hot components (e.g., engine control units) without thermal derating penalties typical of 150 °C parts. |
| True standard-level gate | VGS(th) > 1 V at 175 °C ensures guaranteed turn-on with 5 V microcontroller outputs even at maximum operating temperature. |
| Repetitive avalanche rated | 11.6 mJ single-pulse EAS supports unclamped inductive switching in solenoid and motor phase control without external protection. |
Applications
| Transmission Solenoid Control | Engine Cooling Fan Drive |
|---|---|
|
Use Scenario: Precise PWM-controlled activation of hydraulic solenoids in automatic transmission valve bodies. IC Role / Device Role / Timing Role: Dual-channel high-side switch - one FET drives solenoid coil, the other handles diagnostic feedback or auxiliary valve. Use Value: 45 mΩ RDS(on) limits self-heating during 100% duty-cycle hold; 175 °C rating sustains operation inside sealed transmission control module. |
Use Scenario: High-current DC brushless fan motor commutation in engine bay cooling systems. IC Role / Device Role / Timing Role: Half-bridge upper-arm switch - paired with external low-side FET to form synchronous buck or 3-phase driver stage. Use Value: Low QGD (3.5 nC) reduces gate drive power and improves switching timing accuracy; avalanche rating absorbs back-EMF spikes. |
| 12 V Battery Disconnect Switch | Electric Power Steering (EPS) Motor Phase |
|
Use Scenario: Solid-state replacement for mechanical relays in battery management systems for start-stop vehicles. IC Role / Device Role / Timing Role: Dual-pole main power switch - both FETs conduct in parallel to halve effective RDS(on) and thermal load. Use Value: Parallel drain pins (pins 5/6 and 7/8) reduce package resistance and inductance, minimizing voltage overshoot during fast turn-off. |
Use Scenario: High-reliability phase-leg switching in 12 V EPS motor inverters subject to vibration and thermal cycling. IC Role / Device Role / Timing Role: Independent phase switch - each FET controls one motor winding end; isolation prevents cross-conduction faults. Use Value: AEC-Q101 qualification and 175 °C rating ensure functional safety compliance (ISO 26262 ASIL-B ready) without derating. |
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) at 10 V, but single-channel only; requires two devices for dual function. | Lacks integrated dual topology - increases PCB area, gate drive complexity, and thermal asymmetry vs. monolithic BUK7K52-60EX. | Select when ultra-low RDS(on) is prioritized over integration and board space; verify dual-device thermal coupling. |
| ON Semiconductor NTMFD4C03NT1G | 40 V VDS, 3.3 mΩ RDS(on), LFPAK56 package - lower voltage rating, higher current capability. | Not suitable for 60 V transient-tolerant automotive systems; limited to 24 V or lower nominal rails. | Choose only for 12–24 V non-transient-critical applications where peak VDS remains <45 V; avoid in transmission or EPS. |
Compared with STL220N6F7 and NTMFD4C03NT1G, BUK7K52-60EX uniquely delivers dual-channel integration, 60 V rating, and AEC-Q101 qualification in one thermally optimized package - reducing system BOM count, layout complexity, and qualification effort for 12 V automotive power switching.

FAQ
Is BUK7K52-60EX pin-compatible with earlier BUK7K52-60E?
Yes - BUK7K52-60EX is a direct replacement for BUK7K52-60E with identical pinout (SOT1205), electrical specifications, and thermal performance. The 'X' suffix denotes updated manufacturing process and extended traceability per Nexperia's product change notification policy, with no functional or mechanical changes.
Can both FETs be paralleled for higher current handling?
No - the two FETs are electrically isolated with separate sources and gates; paralleling requires matched gate drive, current sharing resistors, and careful layout to avoid imbalance. For higher current, use the device in dual-load configuration or select a single-channel part with lower RDS(on).
What is the maximum recommended PCB copper area for thermal performance?
Nexperia specifies a minimum footprint for Rth(j-a) = 95 K/W, but optimal thermal performance uses ≥200 mm² of 2 oz copper connected directly to the exposed mounting base (pin 1–4 side). Thermal vias (≥8 × 0.3 mm) to inner ground planes further reduce Rth(j-mb) by ~15%.
Does BUK7K52-60EX include integrated gate protection diodes?
No - it has no built-in gate protection. External Zener clamps (e.g., 12 V, 0.5 W) between G1–S1 and G2–S2 are required to limit VGS to ±20 V under ESD or inductive coupling events, especially in high-noise automotive environments.
