Product details
Overview
BUK7606-75B,118 from Nexperia is an AEC-Q101 qualified N-channel TrenchMOS FET in D2PAK (SOT404) package, designed for automotive power switching. It delivers 75 V VDS, 75 A continuous drain current at Tmb = 25 °C, and 4.8 mΩ typical RDS(on) at VGS = 10 V and Tj = 25 °C, enabling high-efficiency 12 V/24 V load control in thermally demanding environments up to 175 °C junction temperature.
For engineers reviewing the BUK7606-75B,118 datasheet, BUK7606-75B,118 pinout, BUK7606-75B,118 application, or BUK7606-75B,118 equivalent, key selection criteria include its standard-level gate drive compatibility (VGS(th) = 2–4 V), avalanche ruggedness (852 mJ), and mounting-base thermal resistance of 0.5 K/W - critical for automotive motor, lamp, and solenoid driver designs requiring robust transient handling and thermal stability.
Technical Context
This device implements a trench-gate MOSFET structure optimized for low conduction loss and high surge capability. Its gate threshold voltage (2–4 V at 25 °C) ensures reliable turn-on with standard 5 V or 12 V logic-level drivers, while the 175 °C maximum junction temperature rating supports operation in under-hood automotive environments without derating penalties.
The integrated source-drain diode exhibits 0.85–1.2 V forward voltage at 40 A and 25 °C, with 86 ns reverse recovery time and 253 nC recovered charge - parameters directly influencing commutation losses in inductive switching applications such as brushed DC motor control and solenoid actuation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 75 V - Maximum drain-source blocking voltage; defines safe operating range for 42 V automotive systems and 24 V industrial loads. |
| ID (continuous) | 75 A at Tmb = 25 °C - Package-limited current capacity; enables high-power switching without external heatsink in moderate-duty cycles. |
| RDS(on) | 4.8 mΩ typ @ VGS = 10 V, ID = 25 A, Tj = 25 °C - Low on-resistance minimizes conduction loss (Pcond ≈ 0.3 W @ 25 A), reducing thermal stress in sustained-load applications. |
| EAS | 852 mJ - Non-repetitive avalanche energy rating; allows safe clamping of inductive kickback in solenoid/motor circuits without external snubbers. |
| Rth(j-mb) | 0.5 K/W - Junction-to-mounting-base thermal resistance; enables direct thermal coupling to PCB copper or heatsink for efficient heat extraction in space-constrained modules. |
| QG(tot) | 91 nC - Total gate charge; determines gate driver power requirement and switching speed trade-off in PWM-controlled loads. |
Pinout & Package
Package: D2PAK (SOT404), plastic single-ended surface-mounted package with 3 leads (one lead 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; accepts standard-level gate drive (VGS(th) = 2–4 V); requires <10 Ω series resistance to limit ringing during fast switching. |
| 2 (D) | Drain | Main high-side power terminal; internally connected to mounting base; must be soldered to large copper area for thermal management. |
| 3 (S) | Source | Power return path and reference for gate drive; internal source inductance (7.5 nH) impacts high-di/dt switching behavior. |
Key Features

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 |
|---|---|---|---|
| STL220N6F7AG | 60 V VDS, 220 A ID, 1.2 mΩ RDS(on), PowerFLAT 5x6 package; higher current but lower voltage rating. | Not suitable for 42 V systems due to 60 V max rating; better for 12 V high-current inverters where space permits larger package. | Select only if 12 V-only operation and >150 A peak current are required; verify thermal interface compatibility with PowerFLAT footprint. |
| IRF1404ZLPbF | 40 V VDS, 180 A ID, 3.8 mΩ RDS(on), TO-220AB package; non-AEC qualified, higher RDS(on) at elevated temperature. | Lacks automotive qualification and 175 °C rating; unsuitable for safety-critical or high-temperature under-hood use. | Acceptable only for non-automotive 12 V industrial controls where AEC-Q101 compliance and extended temperature range are not mandated. |
Compared with STL220N6F7AG and IRF1404ZLPbF, the BUK7606-75B,118 uniquely balances 75 V rating, AEC-Q101 qualification, and D2PAK thermal performance - making it the only option among the three validated for 42 V mild hybrid switching and sustained 175 °C junction operation.

FAQ
What is the maximum continuous drain current for BUK7606-75B,118 at 100 °C mounting base temperature?
At Tmb = 100 °C, the maximum continuous drain current is 75 A per the limiting values table - capped by package thermal limits rather than silicon capability. This value remains constant from 25 °C to 100 °C mounting base temperature, as shown in Figure 1 of the datasheet, before decreasing above 100 °C due to thermal derating.
Does BUK7606-75B,118 require a gate driver IC for automotive 12 V microcontroller interfacing?
No - its gate threshold voltage (2–4 V at 25 °C) and low total gate charge (91 nC) allow direct drive from standard 5 V or 3.3 V automotive MCUs with appropriate series gate resistance (typically 10–22 Ω). However, for high-frequency PWM (>20 kHz) or high-di/dt loads, a dedicated gate driver improves switching efficiency and EMI performance.
How is the mounting base (mb) electrically connected in the D2PAK package?
The mounting base is internally connected to the drain terminal (Pin 2), forming a low-inductance, high-current path and serving as the primary thermal interface. It must be soldered to a large copper pour or heatsink; electrical isolation from chassis ground is required unless drain-referenced topology is intentionally used.
Can BUK7606-75B,118 replace mechanical relays in 24 V commercial vehicle applications?
Yes - its 75 A continuous current, 852 mJ avalanche energy, and AEC-Q101 qualification make it suitable for solid-state relay replacement in 24 V solenoid, compressor, and air-valve control. Designers must ensure adequate PCB copper area for thermal dissipation and include TVS protection on the gate for load dump transients per ISO 7637-2.
