Product details
Overview
BUK6215-75C,118 from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS FET in DPAK (SOT428) package, designed for high-reliability 12 V automotive power switching. It delivers 57 A continuous drain current at 25 °C mounting base temperature, 12.5 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C, and supports operation up to 175 °C junction temperature - enabling use in engine management, electric power steering, and Start-Stop micro-hybrid systems.
For engineers reviewing the BUK6215-75C,118 datasheet, BUK6215-75C,118 pinout, BUK6215-75C,118 application, or BUK6215-75C,118 equivalent, key selection criteria include logic-level gate drive compatibility, avalanche ruggedness (94 mJ unclamped), thermal resistance (1.17 K/W j-mb), and automotive-grade qualification per AEC-Q101.
Technical Context
This device implements a trench-gate MOSFET architecture optimized for low conduction loss and fast switching in 12 V automotive systems. Its gate threshold voltage (VGS(th)) ranges from 1.8 V to 2.8 V at 25 °C, ensuring reliable turn-on with standard 5 V or 3.3 V logic drivers. The integrated source-drain diode exhibits 0.8–1.2 V forward voltage at 25 A and 25 °C, supporting bidirectional current handling in motor control and solenoid drive.
Thermal design centers on the mounting base (mb), which is internally connected to the drain and serves as the primary heat path. With Rth(j-mb) = 1.17 K/W and Ptot = 128 W at Tmb = 25 °C, it enables high-power density layouts when soldered to a thermally enhanced PCB copper area. Dynamic parameters - including QGD = 18.8 nC and tf = 69 ns - support efficient PWM operation in transmission control and lamp dimming circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 75 V maximum - supports full 12 V automotive battery transient protection (e.g., load dump up to +75 V). |
| ID (continuous) | 57 A at Tmb = 25 °C - enables direct replacement of mechanical relays in high-current loads like fuel pumps and HVAC blowers. |
| RDS(on) | 12.5 mΩ typ. at VGS = 10 V, ID = 15 A, Tj = 25 °C - reduces conduction loss to ≤2.8 W at 15 A, minimizing heatsink requirements. |
| EAS | 94 mJ non-repetitive avalanche energy - provides robustness against inductive kickback in solenoid and motor commutation without external snubbers. |
| Tj max | 175 °C - allows operation in under-hood environments where ambient temperatures exceed 125 °C. |
| Rth(j-mb) | 1.17 K/W - defines thermal bottleneck between die and PCB copper; requires ≥250 mm² 2-oz copper pad for rated power dissipation. |
| QG(tot) | 61.8 nC at VGS = 10 V - determines gate driver current requirement (~62 mA avg. for 1 µs turn-on time). |
Pinout & Package
Package: SOT428 (DPAK), plastic single-ended surface-mounted package with 3 leads (one lead cropped); mounting base (mb) is electrically connected to drain and serves as primary thermal interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Controls channel conduction; accepts logic-level (≥4.5 V) or standard 10 V gate drive; input capacitance Ciss = 2920–3900 pF. |
| 2 (D) | Drain | Main high-side power terminal; internally bonded to mounting base (mb) - must be soldered to thermal pad for rated power handling. |
| 3 (S) | Source | Power return path; referenced to system ground in low-side switch configurations; source inductance LS = 7.5 nH affects switching ringing. |
| mb | Mounting Base | Electrically tied to drain; primary thermal path to PCB; not a signal pin - requires minimum 250 mm² copper area for 128 W dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine bay and transmission control modules - ensures reliability over 15-year vehicle lifetime. |
| Logic- and standard-level gate drive compatible | VGS(th) = 1.8–2.8 V enables direct drive from MCU GPIOs or automotive CAN/LIN transceiver outputs without level-shifting. |
| 175 °C junction rating | Supports continuous operation in thermally constrained locations such as ECU housings near exhaust manifolds or turbochargers. |
| 94 mJ unclamped avalanche energy | Withstands repetitive inductive switching events in motor drives without derating - eliminates need for external clamping diodes in many designs. |
| Low RDS(on) at 4.5 V gate drive | 15.3 mΩ typ. at VGS = 4.5 V - maintains <3 W conduction loss at 15 A even with degraded gate drive voltage during cold-cranking. |

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 |
|---|---|---|---|
| STL220N4F7AG | 75 V VDS, 220 A ID, 3.7 mΩ RDS(on) - larger die, higher current, lower RDS(on), but TO-263 package (not DPAK). | Requires larger PCB footprint and different thermal layout; suited for next-gen 48 V mild-hybrid systems, not drop-in for existing DPAK footprints. | Select only if board redesign permits TO-263 and system demands >100 A continuous current. |
| IRF1404ZPBF | 40 V VDS, 202 A ID, 4.7 mΩ RDS(on) - lower voltage rating, no AEC-Q101 qualification, TO-220AB package. | Not suitable for 12 V automotive transients; lacks automotive qualification and high-temperature reliability data. | Acceptable only for non-automotive industrial motor control where 40 V rating and commercial qualification suffice. |
Compared with STL220N4F7AG and IRF1404ZPBF, BUK6215-75C,118 uniquely balances DPAK-compatible form factor, AEC-Q101 compliance, 75 V rating, and 12.5 mΩ RDS(on) - making it the only qualified solution for space-constrained, thermally demanding 12 V automotive power stages without package or qualification compromise.

FAQ
Is BUK6215-75C,118 pin-compatible with other DPAK-packaged N-channel MOSFETs?
Yes - it uses the standard SOT428 (DPAK) outline with 3 leads (G-D-S) and mounting base tied to drain. Pin 1 is gate, Pin 2 is drain/mounting base, Pin 3 is source. Mechanical footprint matches JEDEC TO-252, enabling PCB reuse across qualified DPAK MOSFETs.
What gate resistor value is recommended for optimal switching performance?
A 10 Ω external gate resistor is specified in the datasheet for characterization (td(on) = 16.6 ns, tf = 69 ns). For EMI-sensitive applications, 22–47 Ω reduces dV/dt; for high-frequency PWM (>50 kHz), ≤5 Ω minimizes switching loss while maintaining stability with typical 1–2 A gate drivers.
Does BUK6215-75C,118 require a heatsink in automotive applications?
No discrete heatsink is required if the mounting base is soldered to ≥250 mm² of 2-oz copper on the PCB with ≥6 thermal vias (0.3 mm diameter, 1 mm pitch). At Tmb = 100 °C, continuous current derates to 41 A - sufficient for most 12 V solenoid and motor control loads.
Can BUK6215-75C,118 be used in synchronous rectification topologies?
No - it is a standard-level enhancement-mode MOSFET with no integrated Schottky body diode optimization. Its source-drain diode has 51 ns reverse recovery time and 117 nC recovered charge, making it unsuitable for high-frequency synchronous rectification where fast recovery and low Qr are critical.
