Product details
Overview
BUK7107-55ATE,118 from NXP Semiconductors is a standard-level N-channel TrenchPLUS MOSFET in D2PAK (SOT426) package, rated for 55 V VDS, 140 A continuous drain current at Tmb = 25 °C, and 7 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C. It integrates ESD protection diodes and a calibrated temperature-sensing diode, and is AEC-Q101 qualified for automotive power switching.
For engineers reviewing the BUK7107-55ATE,118 datasheet, BUK7107-55ATE,118 pinout, BUK7107-55ATE,118 application, or BUK7107-55ATE,118 equivalent, this device supports high-current, thermally monitored switching in EPAS, fan control, and variable valve timing systems where robust avalanche energy (460 mJ), low gate charge (116 nC), and junction-to-mounting-base thermal resistance (0.55 K/W) are critical selection criteria.
Technical Context
This MOSFET employs TrenchMOS technology with integrated TrenchPLUS diodes for ESD protection and precision temperature sensing via a forward-biased diode (VF(TSD) = 658 mV typ at 25 °C, -1.54 mV/K tempco). Its gate threshold voltage (VGS(th)) ranges from 2 V to 4 V at 25 °C and remains functional down to 1 V at 175 °C, enabling reliable turn-on with standard 10 V gate drive.
The device features low parasitic inductance (LD = 2.5 nH, LS = 7.5 nH), fast switching (tr = 115 ns, tf = 111 ns), and unclamped avalanche ruggedness of 460 mJ - critical for inductive load handling in automotive motor drives without external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V maximum drain-source voltage - defines safe operating ceiling for 48 V automotive systems and transient overvoltage tolerance. |
| RDS(on) | 5.8 mΩ typical at VGS = 10 V, ID = 50 A, Tj = 25 °C - enables <1 W conduction loss at 40 A, reducing heatsink requirements. |
| ID (continuous) | 140 A at Tmb = 25 °C - supports high-power loads like electric power steering motors when mounted on thermally optimized PCBs. |
| EAS | 460 mJ non-repetitive avalanche energy - allows safe operation during inductive flyback events without external clamping. |
| VESD | 6 kV HBM - eliminates need for external ESD protection in assembly and end-use environments. |
| Tj max | 175 °C - enables operation in under-hood automotive locations with minimal derating. |
| QG(tot) | 116 nC total gate charge - balances switching speed and driver power consumption in 20–100 kHz PWM applications. |
Pinout & Package
Package: D2PAK (SOT426), plastic single-ended surface-mounted package with 5 leads (one cropped); mounting base (mb) electrically connected to drain and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | G (Gate) | Control terminal; requires ≤20 V gate-source voltage; 116 nC total charge dictates driver strength requirement. |
| 2 | A (Anode) | Anode of integrated ESD protection diode - connects internally to gate for bidirectional electrostatic discharge clamping. |
| 3 | D (Drain) | Main power output node; electrically tied to mounting base for low-inductance, high-current return path and thermal conduction. |
| 4 | K (Cathode) | Cathode of integrated ESD protection diode - connects internally to gate, completing bidirectional clamp circuit. |
| 5 | S (Source) | Power return reference; isolated from mounting base; used for current sensing and gate drive referencing. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated temperature-sensing diode | Calibrated forward voltage (658 mV typ at 25 °C) with -1.54 mV/K coefficient - enables real-time junction temperature monitoring without external sensors. |
| TrenchPLUS ESD protection | Built-in anode-cathode diode pair across gate - provides 6 kV HBM robustness, eliminating discrete TVS components in gate drive circuits. |
| AEC-Q101 qualification | Validated for automotive critical applications including EPAS and engine control - ensures reliability under extended temperature cycling and vibration stress. |
| Low RDS(on) × QG figure-of-merit | 5.8 mΩ × 116 nC = 673 mΩ·nC - optimizes trade-off between conduction loss and switching loss in high-frequency motor control. |
| Mounting-base thermal interface | Rth(j-mb) = 0.55 K/W - enables direct thermal coupling to heatsinks or copper planes, supporting >200 W dissipation with proper layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N4LF8AG | 40 V VDS, 220 A ID, 1.2 mΩ RDS(on), no integrated temperature diode, PowerFLAT 5x6 package | Limited to 36 V systems; lacks on-die thermal sensing; higher current but lower voltage rating | Select when higher current and lower RDS(on) are prioritized over thermal monitoring and 48 V compatibility. |
| IRFB4115PBF | 150 V VDS, 110 A ID, 6.5 mΩ RDS(on), TO-220AB package, no ESD diodes or temperature sensor | Higher voltage margin but larger footprint; requires external ESD protection and thermal sensor | Choose for industrial 100–120 V applications where automotive qualification is not required and board space permits TO-220 mounting. |
Compared with STL220N4LF8AG and IRFB4115PBF, the BUK7107-55ATE,118 uniquely combines 55 V rating, AEC-Q101 qualification, integrated ESD protection, and calibrated temperature sensing in a thermally optimized D2PAK package - making it the only option among the three suitable for thermally aware, safety-critical 48 V automotive switching without added components.

FAQ
What is the maximum continuous drain current for BUK7107-55ATE,118 at 100 °C mounting base temperature?
At Tmb = 100 °C, the maximum continuous drain current is 75 A, as specified in Table 4 (Limiting Values) of the datasheet. This derating reflects thermal constraints of the D2PAK package and junction-to-mounting-base thermal resistance (0.55 K/W), not silicon limitations.
Does BUK7107-55ATE,118 require external gate resistors for ESD protection?
No. The device integrates TrenchPLUS diodes connecting gate to source and drain, providing 6 kV HBM ESD protection per IEC 61000-4-2. External gate resistors are still recommended for switching control (e.g., 10 Ω for turn-on/turn-off shaping), but not for ESD clamping.
How is the temperature-sensing diode calibrated and what accuracy can be expected?
The diode exhibits a typical forward voltage of 658 mV at 25 °C and a temperature coefficient of -1.54 mV/K. Calibration is factory-trimmed; datasheet specifies ±10 mV hysteresis and ±0.1 V absolute accuracy over -55 °C to 175 °C, enabling ±2–3 °C junction temperature measurement with proper bias current (250 µA).
Can BUK7107-55ATE,118 be used in high-frequency PWM applications above 50 kHz?
Yes - its 116 nC total gate charge, 115 ns rise time, and 111 ns fall time support operation up to 100 kHz. However, switching losses increase significantly above 50 kHz; thermal design must account for combined conduction and switching dissipation, especially given its 272 W Ptot limit at Tmb = 25 °C.
