Product details

Overview

BUK7607-30B,118 from Nexperia is a standard-level N-channel TrenchMOS FET in D2PAK (SOT404) package, rated for 30 V V_DS, 75 A continuous drain current at T_mb = 25 °C, and 175 °C junction temperature. It delivers 5.9 mΩ R_DS(on) at V_GS = 10 V and I_D = 25 A, T_j = 25 °C, and is AEC-Q101 qualified for automotive critical power switching applications including solenoids, lamps, and 12 V motor control.

For engineers reviewing the BUK7607-30B datasheet, BUK7607-30B pinout, BUK7607-30B application, or BUK7607-30B equivalent, this device supports thermally demanding automotive environments, requires standard 10 V gate drive, and provides robust unclamped avalanche energy handling (329 mJ) - key selection criteria for high-reliability 12 V load switching.

Technical Context

This MOSFET employs TrenchMOS technology to achieve low conduction losses and stable threshold voltage across temperature (V_GS(th) = 2–4 V at T_j = 25 °C). Its thermal resistance from junction to mounting base is 0.95 K/W, enabling high-power dissipation when mounted on heatsinked PCBs.

The device features fast switching dynamics (t_d(on) = 20 ns, t_f = 44 ns), low gate charge (Q_G(tot) = 36 nC), and integrated source-drain diode with V_SD = 0.85–1.2 V at I_S = 25 A, supporting bidirectional current paths in inductive load circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V maximum drain-source voltage - defines safe operating ceiling for 12 V automotive systems with transient spikes up to 30 V.
I_D (continuous)	75 A at T_mb = 25 °C - limited by package thermal capability, suitable for high-current solenoid or lamp drivers without forced cooling.
R_DS(on)	5.9 mΩ typical at V_GS = 10 V, I_D = 25 A, T_j = 25 °C - enables <1.5 W conduction loss at 25 A, reducing heatsink requirements.
E_AS	329 mJ non-repetitive avalanche energy - sustains unclamped inductive turn-off events in motor/solenoid circuits without failure.
T_j max	175 °C maximum junction temperature - supports operation in under-hood environments and enables extended thermal margin during overload conditions.
Q_G(tot)	36 nC total gate charge - determines gate driver strength requirement; compatible with standard automotive logic-level drivers (e.g., UCC27531).
R_th(j-mb)	0.95 K/W junction-to-mounting-base thermal resistance - enables direct thermal coupling to heatsinks or copper planes for efficient power dissipation.

Pinout & Package

Package: D2PAK (SOT404), plastic single-ended surface-mounted package with 3 leads (one lead cropped); mounting base electrically connected to drain terminal.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Controls channel conduction; requires 10 V nominal drive for full enhancement; gate leakage <100 nA ensures low standby power.
2 (D)	Drain	Main high-side power path; internally connected to mounting base - must be thermally and electrically tied to heatsink or ground plane.
3 (S)	Source	Power return path and reference for gate drive; internal source inductance 7.5 nH affects high-speed switching stability.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive safety-critical applications including engine control, body electronics, and ADAS power stages.
Low R_DS(on) at 10 V drive	5.9 mΩ typ. enables efficient 12 V load switching without requiring gate boosters or level shifters.
175 °C junction rating	Supports sustained operation in under-hood ambient temperatures up to 125 °C with sufficient thermal design margin.
Unclamped avalanche ruggedness	329 mJ energy rating allows reliable handling of inductive kickback from motors, solenoids, and relays.
Thermally optimized D2PAK	Mounting base directly bonded to drain enables <1 K/W thermal path to heatsink - critical for high-current automotive modules.

Applications

IC Role / Device Role / Timing Role: Low-side switching element in half-bridge configuration; handles 40–60 A peak currents during startup.

Use Value: 175 °C rating prevents thermal shutdown during hot-soak conditions; avalanche ruggedness absorbs back-EMF during abrupt stop commands.

Truck Headlamp Dimming Circuit

Commercial Vehicle Air Suspension Valve

Use Scenario: Switching high-intensity halogen or LED headlamps in heavy-duty trucks, where load currents exceed 30 A per channel.

IC Role / Device Role / Timing Role: Standard-level N-channel FET used in high-side configuration with gate driver IC (e.g., TPS28225).

Use Value: 75 A continuous rating supports dual-lamp operation; low Q_G enables clean PWM dimming at 200–500 Hz without shoot-through risk.

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
STL220N3LLH6	30 V, 220 A, 1.8 mΩ R_DS(on), PowerFLAT 5x6 package; higher current, lower R_DS(on), but no mounting base - requires external heatsink.	Preferred for space-constrained PCBs needing >100 A capability; unsuitable where mechanical mounting base is required for thermal interface.	Select when board area is limited and thermal interface can be engineered externally; not drop-in due to different footprint and thermal path.
IRF3205PBF	55 V, 110 A, 8.0 mΩ R_DS(on), TO-220AB package; higher voltage rating but larger package, no AEC-Q101 qualification.	Used in industrial 24 V systems; lacks automotive qualification and thermal performance at 175 °C.	Acceptable for non-automotive 12/24 V loads where qualification and junction temperature margin are not required.

Compared with STL220N3LLH6 and IRF3205PBF, the BUK7607-30B uniquely combines AEC-Q101 qualification, D2PAK mounting base for direct heatsinking, and optimal 30 V/75 A balance - making it the preferred choice for production automotive 12 V power modules where reliability, thermal integration, and qualification are mandatory.

FAQ

Is BUK7607-30B,118 suitable for high-side switching in 12 V automotive systems?

Yes - it supports high-side configuration when paired with an appropriate gate driver (e.g., TPS28225 or NCV8405) that provides 10 V gate voltage referenced to the drain potential. Its 30 V V_DS rating accommodates load-dump transients common in automotive 12 V networks, and its 175 °C junction rating ensures reliability under hood thermal stress.

What is the significance of the mounting base being connected to the drain terminal?

The mounting base is electrically tied to the drain, enabling direct thermal coupling to a heatsink while simultaneously serving as the primary high-current drain path. This eliminates need for separate thermal vias or solder pads, reduces parasitic inductance in high-current loops, and simplifies mechanical integration in automotive modules where chassis grounding is often drain-referenced.

Does BUK7607-30B,118 require a gate resistor for automotive PWM applications?

Yes - a series gate resistor (typically 10–22 Ω) is recommended to dampen ringing caused by gate-drain capacitance (Crss = 256–351 pF) and internal source inductance (7.5 nH), especially in high-frequency PWM (>1 kHz) or high-di/dt motor/solenoid switching. This prevents false turn-on and improves EMI performance in noisy automotive environments.

How does the 329 mJ avalanche energy rating translate to real-world circuit protection?

This rating means the device can absorb a single 329 mJ unclamped inductive energy spike - equivalent to interrupting 75 A through a 58 µH inductor at 30 V - without failure. In practice, it protects against worst-case solenoid or fan motor turn-off events where freewheeling diodes are absent or insufficient, eliminating need for external snubbers in many automotive designs.
