Product details
Overview
BUK7Y7R2-60EX from Nexperia is a standard-level N-channel MOSFET rated for 60 V drain-source voltage, 7.2 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C, and 100 A continuous drain current at Tmb = 25 °C. It uses TrenchMOS technology in LFPAK56 (SOT669) package and is AEC-Q101 qualified for automotive power switching applications including transmission control and solenoid drivers.
For engineers reviewing the BUK7Y7R2-60EX datasheet, BUK7Y7R2-60EX pinout, BUK7Y7R2-60EX application, or BUK7Y7R2-60EX equivalent, key selection criteria include its 175 °C junction rating, repetitive avalanche capability, true standard-level gate threshold (>1 V at 175 °C), and thermal resistance of 0.9 K/W from junction to mounting base.
Technical Context
This MOSFET employs TrenchMOS silicon architecture optimized for low conduction loss and fast switching in high-current DC power paths. Its gate threshold voltage remains functional up to 175 °C, enabling reliable operation in thermally demanding under-hood environments without requiring elevated gate drive.
The device integrates a robust intrinsic body diode with 27.1 ns reverse recovery time and 25.6 nC recovered charge, supporting synchronous rectification and freewheeling in inductive load circuits. Its 88.2 mJ non-repetitive avalanche energy rating supports unclamped inductive switching events common in motor and solenoid control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum drain-source blocking voltage; suitable for 48 V automotive systems with margin. |
| RDS(on) | 7.2 mΩ max at VGS = 10 V, ID = 25 A, Tj = 25 °C - Enables <1 W conduction loss at 50 A, reducing heatsink requirements. |
| ID (continuous) | 100 A at Tmb = 25 °C - Package-limited current capacity; derates to 72 A at Tmb = 100 °C. |
| EAS | 88.2 mJ - Non-repetitive avalanche energy; supports safe turn-off into inductive loads without external snubbers. |
| Rth(j-mb) | 0.9 K/W - Thermal resistance from junction to mounting base; enables efficient PCB copper pour cooling in high-power layouts. |
| VGS(th) | >1 V at Tj = 175 °C - Ensures gate turn-on remains functional across full automotive temperature range without special biasing. |
| QGD | 15.8 nC - Gate-drain charge; determines Miller plateau duration and influences switching loss in hard-switched topologies. |
Pinout & Package
LFPAK56 (SOT669) is a 4-lead surface-mount power package with exposed mounting base connected to drain. It delivers superior thermal and electrical performance versus SO-8, with 0.9 K/W junction-to-mounting-base thermal resistance and low-inductance source connections.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source (S) | Three parallel source terminals reduce package inductance and improve current sharing in high-di/dt switching. |
| 4 | Gate (G) | Single gate input with 50.8 nC total gate charge; requires ~5 Ω external gate resistor for controlled 10–20 ns rise/fall times. |
| Mounting Base | Drain (D) | Exposed copper pad electrically connected to drain; serves as primary thermal path and high-current return node. |
Key Features
| Feature | Design Value |

| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22 standards. |
| Repetitive avalanche rated | Rated for repeated unclamped inductive switching events up to specified EAS, enabling robust solenoid/motor control. |
| 175 °C maximum junction temperature | Supports operation in engine bay and transmission control modules without derating beyond ambient limits. |
| True standard-level gate | VGS(th) > 1 V at 175 °C ensures compatibility with 5 V or 3.3 V microcontroller GPIO without level-shifting. |
| Low RDS(on) × QG figure-of-merit | 7.2 mΩ × 50.8 nC = 366 mΩ·nC - Balances conduction and switching losses for high-efficiency 12–48 V DC-DC and load switching. |

FAQ
Is BUK7Y7R2-60EX pin-compatible with other LFPAK56 MOSFETs?
Yes - BUK7Y7R2-60EX uses the standard SOT669 footprint with identical pin assignment (pins 1–3 = source, pin 4 = gate, mounting base = drain). It is mechanically and electrically compatible with all Nexperia LFPAK56 N-channel MOSFETs, enabling drop-in replacement within the same voltage and current class when thermal and switching requirements align.
What is the maximum recommended gate resistor value for driving BUK7Y7R2-60EX in a 12 V automotive load switch?
For 12 V load switching with <20 ns rise/fall times and minimal overshoot, a 4.7 Ω to 10 Ω gate resistor is recommended. This range balances switching speed against ringing and EMI, given the device's 50.8 nC total gate charge and 15.8 nC gate-drain charge. Lower values increase dV/dt stress; higher values extend switching losses.
Does BUK7Y7R2-60EX require a gate driver IC in automotive applications?
No - its standard-level gate (VGS(th) > 1 V at 175 °C) allows direct drive from 3.3 V or 5 V microcontroller GPIOs. However, for high-frequency PWM (>10 kHz) or high-current loads (>30 A), a dedicated gate driver improves switching consistency, reduces MCU loading, and enhances noise immunity in noisy automotive environments.
How does the mounting base connection affect PCB layout for thermal performance?
The mounting base must be soldered to a minimum 25 mm² copper pour (2 oz. thickness) with ≥6 thermal vias (0.3 mm diameter) connecting to inner ground/power planes. This configuration achieves near-spec Rth(j-mb) = 0.9 K/W; insufficient copper area or via count increases junction temperature by 20–40 °C at 75 A, risking thermal shutdown or accelerated wear.
