Product details
Overview
BUK7Y6R0-60EX from Nexperia is a standard-level N-channel MOSFET rated for 60 V drain-source voltage, 4 mΩ typical RDS(on) at 10 VGS and 25 A, and qualified to AEC-Q101 for automotive use. It delivers 100 A continuous drain current at Tmb = 25 °C in LFPAK56 (SOT669) package, with true standard gate drive compatibility (VGS(th) > 1 V at 175 °C), enabling direct replacement of legacy logic-level drivers in high-reliability 12 V systems.
For engineers reviewing the BUK7Y6R0-60EX datasheet, BUK7Y6R0-60EX pinout, BUK7Y6R0-60EX application, or BUK7Y6R0-60EX equivalent, key selection criteria include its 175 °C junction rating, repetitive avalanche capability, low thermal resistance (0.77 K/W j-to-mb), and validated performance in thermally constrained motor/solenoid control circuits.
Technical Context
This MOSFET employs TrenchMOS technology in an LFPAK56 package, integrating a robust source-drain diode with 29 ns reverse recovery time and 29 nC recovered charge. Its gate threshold remains functional up to 175 °C, ensuring stable turn-on behavior across full automotive temperature range without requiring gate voltage boosting.
The device features a mounting-base-connected drain (mb) terminal for direct thermal coupling to heatsinks, and its 4-pin configuration places three parallel source terminals to minimize bond-wire inductance and resistive loss-critical for high-current switching transients and avalanche energy handling (127 mJ unclamped).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V maximum - supports full 12 V automotive battery transient margin (ISO 7637-2 Pulse 5a: +75 V) with safety headroom. |
| RDS(on) | 4 mΩ typ @ VGS = 10 V, ID = 25 A, Tj = 25 °C - enables <1 W conduction loss at 50 A, reducing thermal load in compact modules. |
| ID (cont) | 100 A @ Tmb = 25 °C - limited by package thermal capacity, not silicon, allowing high peak current delivery in short-duty-cycle applications. |
| EAS | 127 mJ non-repetitive avalanche energy - sustains unclamped inductive switching events (e.g., solenoid de-energization) without failure. |
| Rth(j-mb) | 0.77 K/W - enables efficient heat transfer to PCB copper or external heatsink, supporting >85 A continuous operation at Tmb = 100 °C. |
| QGD | 12.1 nC - low gate-drain charge improves switching speed and reduces Miller-induced shoot-through risk in half-bridge configurations. |
| VGS(th) | >1 V @ Tj = 175 °C - ensures reliable turn-on with standard 5 V or 12 V microcontroller GPIOs under worst-case thermal stress. |
Pinout & Package
LFPAK56 (SOT669) is a surface-mount plastic package with exposed mounting base (drain-connected) and four leads: three parallel source pins and one gate pin. Its low-profile design (max height 1.20 mm) and optimized copper clip construction deliver superior power density and thermal performance versus SO-8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 (S) | Source | Three parallel source terminals reduce effective source inductance and resistance, improving current sharing and EMI during fast switching. |
| 4 (G) | Gate | Single gate input with 45.4 nC total gate charge - compatible with standard gate drivers delivering ≥1 A peak output. |
| mb (mounting base) | Drain | Exposed copper pad electrically connected to drain; serves as primary thermal path and high-current return node for PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments including temperature cycling, humidity, and mechanical shock per JESD47. |
| Repetitive avalanche rated | Rated for repeated unclamped inductive switching without degradation - critical for transmission valve control and fuel injector drivers. |
| 175 °C junction rating | Enables operation in engine bay locations where ambient exceeds 125 °C, eliminating need for derating or forced cooling. |
| True standard-level gate | VGS(th) > 1 V at 175 °C ensures consistent turn-on with 5 V/12 V logic without gate boosters or level shifters. |
| Low RDS(on) × QG figure-of-merit | 4 mΩ × 45.4 nC = 182 mΩ·nC - balances conduction and switching losses for high-efficiency 10–100 kHz PWM motor control. |
Applications
| Engine Control Module (ECM) Solenoid Driver | Automotive HVAC Blower Motor Controller |
|---|---|
Use Scenario: Driving 12 V fuel injectors or transmission shift solenoids with 50–100 ms on-time pulses and high inductive kickback. IC Role / Device Role / Timing Role: High-side or low-side power switch handling 5–15 A DC loads with fast turn-off to suppress back-EMF. Use Value: 127 mJ avalanche energy rating absorbs unclamped inductive energy without snubbers; 175 °C rating ensures reliability near hot exhaust manifolds. |
Use Scenario: PWM-controlled blower motor in passenger cabin, operating continuously at 25–80 A with ambient up to 85 °C. IC Role / Device Role / Timing Role: Low-side switching element in H-bridge or single-FET topology, modulated at 10–25 kHz. Use Value: 0.77 K/W thermal resistance maintains Tj < 150 °C at 80 A with minimal heatsinking; 4 mΩ RDS(on) limits conduction loss to <26 W. |
| 12 V Starter Relay Replacement | Electric Power Steering (EPS) Assist Motor Switch |
Use Scenario: Solid-state replacement for electromechanical starter relays in start-stop systems, handling 100–200 A cranking surges. IC Role / Device Role / Timing Role: High-current, low-duty-cycle power switch activated for ≤500 ms during engine cranking. Use Value: 482 A peak drain current (10 µs pulse) and 195 W Ptot support brief high-power bursts without thermal runaway. |
Use Scenario: Torque assist motor control in EPS systems, requiring precise 1–5 kHz PWM with fault tolerance and thermal resilience. IC Role / Device Role / Timing Role: Half-bridge low-side switch in 3-phase inverter, synchronized with gate driver for torque ripple minimization. Use Value: Low QGD (12.1 nC) and fast switching (tf = 21 ns) reduce dead-time distortion; AEC-Q101 qualification ensures ASIL-B compliance readiness. |
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), 220 A ID, PowerFLAT 5x6 package; higher current but larger footprint and no AEC-Q101 certification. | Targeted at industrial motor drives, not automotive-qualified; lacks avalanche rating and 175 °C validation. | Select only if higher current and lower RDS(on) outweigh qualification requirements and board space constraints. |
| IRF1404ZPBF | 40 V, 3.8 mΩ RDS(on), TO-220 package; lower voltage rating and no automotive qualification or thermal performance data above 150 °C. | Suitable for 12 V non-automotive power supplies; cannot withstand ISO 7637-2 transients or extended 175 °C operation. | Use only in cost-sensitive, non-automotive designs where transient immunity and high-temperature reliability are not required. |
Compared with STL220N6F7 and IRF1404ZPBF, BUK7Y6R0-60EX uniquely combines AEC-Q101 qualification, 175 °C operation, 127 mJ avalanche ruggedness, and LFPAK56's superior thermal resistance-making it the only drop-in solution for thermally demanding, safety-critical automotive power switching.

FAQ
Is BUK7Y6R0-60EX pin-compatible with other LFPAK56 MOSFETs?
Yes - BUK7Y6R0-60EX uses the standard SOT669 footprint with identical pin 1–4 assignment (S, S, S, G) and mounting base connection. Mechanical compatibility is confirmed per Nexperia's package outline document sot669_po, enabling direct PCB layout reuse across qualified LFPAK56 N-channel devices.
What is the maximum safe operating temperature for continuous use?
The device is rated for continuous operation with junction temperature up to 175 °C, verified per AEC-Q101 stress testing. At Tmb = 100 °C, it supports 85 A continuous drain current; thermal design must ensure Rth(j-mb) ≤ 0.77 K/W and sufficient copper area under the mounting base to avoid exceeding this limit.
Does BUK7Y6R0-60EX require a gate resistor for automotive EMI compliance?
A gate resistor of 5 Ω is specified in the datasheet for switching characterization (Fig. 14), and recommended for EMI control in automotive applications. This value damps gate ringing, controls di/dt during turn-on/off, and aligns with CISPR 25 Class 5 radiated emission requirements when combined with proper PCB layout and shielding.
Can BUK7Y6R0-60EX replace logic-level MOSFETs in existing 5 V gate-drive designs?
No - BUK7Y6R0-60EX is a standard-level device requiring ≥10 VGS for full enhancement; its VGS(th) > 1 V at 175 °C ensures turn-on but does not guarantee low RDS(on) below 4.5 V. For 5 V logic drive, select Nexperia's BUK9Y series (logic-level) instead.
