Product details

Overview

BUK6211-75C,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 74 A continuous drain current at 25 °C mounting base temperature, 9.3 mΩ R_DS(on) at V_GS = 10 V and T_j = 25 °C, and supports 175 °C junction operation - enabling use in electric power steering and engine management systems.

For engineers reviewing the BUK6211-75C,118 datasheet, BUK6211-75C,118 pinout, BUK6211-75C,118 application, or BUK6211-75C,118 equivalent, key selection criteria include its 75 V V_DS, logic-level gate drive compatibility (V_GS(th) typ. 2.3 V), avalanche ruggedness (127 mJ unclamped), thermal resistance (0.95 K/W j-mb), and automotive qualification status.

Technical Context

This device employs advanced TrenchMOS technology to achieve low on-resistance and fast switching with controlled Q_G (81 nC at V_GS = 10 V) and low C_iss (typ. 3938 pF). Its gate threshold voltage ranges from 0.8 V at 175 °C to 3.3 V at −55 °C, ensuring stable turn-on across automotive temperature extremes.

The integrated source-drain diode exhibits 0.8–1.2 V forward drop at 25 A and 25 °C, with 50.5 ns reverse recovery time and 105 nC recovered charge - supporting synchronous rectification and inductive load commutation in transmission control and start-stop systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	75 V - Maximum blocking voltage compatible with 12 V automotive battery transients (e.g., load dump up to 40 V + margin).
I_D (cont)	74 A at T_mb = 25 °C - Enables high-current motor/solenoid drivers without parallel devices in compact layouts.
R_DS(on)	9.3 mΩ typ. at V_GS = 10 V, T_j = 25 °C - Minimizes conduction loss (<0.5 W at 7.3 A) in thermally constrained ECU modules.
T_j max	175 °C - Allows sustained operation in under-hood environments where ambient exceeds 125 °C.
R_th(j-mb)	0.95 K/W - Enables efficient heat transfer to PCB copper or heatsink via exposed mounting base (drain-connected).
E_AS	127 mJ unclamped avalanche energy - Absorbs inductive kickback from solenoids or motors without external snubbers.
Q_G(tot)	81 nC at V_GS = 10 V - Matches standard gate drivers (e.g., UCC27531) with <1 µs turn-on time using 10 Ω external resistor.

Pinout & Package

BUK6211-75C,118 uses the SOT428 (DPAK) plastic surface-mount package with three leads and an exposed mounting base electrically connected to the drain terminal. The package features a single cropped lead and is optimized for high-power thermal dissipation through soldered mounting base contact.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Logic-level control input; threshold voltage 1.8–2.8 V enables direct MCU GPIO drive without level-shifting.
2 (D)	Drain	Main high-side power path; internally bonded to mounting base for low-inductance, high-current routing.
3 (S)	Source	Power return node; referenced to system ground in low-side switch configurations.
Mounting Base (mb)	Drain (common)	Exposed copper pad soldered to PCB thermal plane; provides primary thermal path (R_th(j-mb) = 0.95 K/W) and structural mechanical anchor.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive applications including power steering and engine control - ensures reliability over 15-year vehicle lifetime.
175 °C junction rating	Enables operation in under-hood locations (e.g., transmission control units) without derating at peak ambient temperatures.
Logic-level gate drive	V_GS(th) typ. 2.3 V allows direct interface with 3.3 V/5 V microcontrollers - eliminates need for gate driver ICs in cost-sensitive designs.
Low R_DS(on) × Q_G figure-of-merit	9.3 mΩ × 81 nC = 753 mΩ·nC - balances conduction and switching losses for high-efficiency PWM motor control.
Unclamped avalanche capability	127 mJ energy rating - sustains repetitive inductive switching events (e.g., fuel injector actuation) without failure.

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	40 V V_DS, 220 A I_D, 0.75 mΩ R_DS(on) - higher current, lower voltage rating.	Targeted at 48 V mild-hybrid systems; not suitable for 12 V load-dump transient immunity.	Select only if system operates below 35 V and requires >150 A capability; verify gate drive compatibility with 4.5 V logic levels.
IRF1404ZLPBF	40 V V_DS, 195 A I_D, 2.7 mΩ R_DS(on), no AEC-Q101 qualification.	Industrial-grade part lacking automotive qualification; unsuitable for safety-critical EPS or EMS functions.	Acceptable only for non-automotive 12 V industrial motor drives where AEC-Q101 is not mandated.

Compared with STL220N4F7AG and IRF1404ZLPBF, BUK6211-75C,118 uniquely combines 75 V rating, AEC-Q101 compliance, and logic-level gate drive - making it the only qualified option for 12 V automotive high-side/low-side switching where transient robustness and qualification are mandatory.

FAQ

Is BUK6211-75C,118 suitable for high-side switching configurations?

Yes - its 75 V V_DS rating and 175 °C junction capability support high-side use in 12 V systems. The mounting base is internally connected to the drain, so PCB layout must isolate the base pad from ground planes when used in high-side topology. Gate drive must provide sufficient voltage headroom above the source potential.

What is the maximum allowable gate-source voltage for continuous operation?

The absolute maximum DC V_GS is ±16 V per the datasheet limiting values table. Exceeding this risks permanent gate oxide damage. For reliable long-term operation, keep V_GS ≤12 V in normal use, especially at elevated temperatures where gate leakage increases.

Does BUK6211-75C,118 include integrated ESD protection?

No - the device does not feature on-chip ESD protection diodes. External TVS or RC snubbers are recommended on gate and drain lines in automotive environments to suppress ISO 10605 pulses and load-dump transients before they reach the MOSFET terminals.

How does R_DS(on) change at elevated junction temperatures?

R_DS(on) increases with temperature: at V_GS = 10 V and I_D = 25 A, it rises from 9.3 mΩ at 25 °C to 28.6 mΩ at 175 °C (typical). This 3× increase must be factored into worst-case conduction loss calculations for thermal design and SOA validation.
