Product details
Overview
BUK7609-75A,118 from Nexperia is an AEC-Q101 qualified N-channel TrenchMOS standard-level power MOSFET in D2PAK (SOT404) package, rated for 75 V VDS, 75 A continuous drain current at Tmb = 25 °C, and 175 °C junction temperature. It delivers 7.7 mΩ typical RDS(on) at 25 °C and supports automotive 12 V/24 V load switching including motors, lamps, and solenoids.
For engineers reviewing the BUK7609-75A datasheet, BUK7609-75A pinout, BUK7609-75A application, or BUK7609-75A equivalent, key selection criteria include its 175 °C thermal rating, 0.65 K/W Rth(j-mb), unclamped avalanche energy of 560 mJ, and compatibility with standard 10 V gate drive sources in thermally demanding environments.
Technical Context
This MOSFET uses TrenchMOS technology to achieve low on-resistance and high avalanche ruggedness. Its gate threshold voltage ranges from 1 V (Tj = 175 °C) to 4.4 V (Tj = −55 °C), enabling robust turn-on control across automotive temperature extremes.
The device features a source-drain diode with 0.85 V forward voltage at 25 A and 75 ns reverse recovery time, supporting inductive load commutation. Internal drain and source inductances are tightly controlled at 2.5 nH (mounting base) and 7.5 nH (lead), minimizing switching oscillation in high-dI/dt applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 75 V - Maximum blocking voltage for 42 V automotive systems with margin against transients. |
| ID (continuous) | 75 A at Tmb = 25 °C - Supports high-current loads like starter relays and HVAC blowers without external heatsink. |
| RDS(on) | 7.7 mΩ typ @ VGS = 10 V, ID = 25 A, Tj = 25 °C - Enables <1 W conduction loss at 40 A, reducing thermal design burden. |
| EAS | 560 mJ unclamped avalanche energy - Withstands inductive kickback from solenoid de-energization without failure. |
| Rth(j-mb) | 0.65 K/W - Enables direct mounting to PCB copper pour or heatsink for efficient thermal transfer in space-constrained modules. |
| QG | ~100 nC (from Fig 9) - Compatible with standard gate drivers (e.g., UCC27531) without requiring oversized drive capability. |
| VGS(th) | 2–4 V @ 25 °C - Ensures reliable turn-on with 3.3 V or 5 V logic-level controllers when used with gate boosting. |
Pinout & Package
Package: D2PAK (SOT404), plastic single-ended surface-mounted package with 3 leads (one lead cropped); mounting base (mb) electrically connected to drain.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; requires 10 V drive for full enhancement; gate leakage <100 nA ensures low standby current. |
| 2 (D) | Drain | Main power output; internally bonded to mounting base for low-inductance, high-current path to heatsink. |
| 3 (S) | Source | Power return; referenced to system ground; internal source inductance (7.5 nH) impacts high-speed switching ringing. |
| Mounting Base (mb) | Drain Connection | Exposed metal pad tied directly to drain; provides primary thermal path and must be soldered to ≥100 mm² copper area for rated power dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive safety-critical applications including engine control and chassis systems. |
| 175 °C maximum junction temperature | Enables operation in under-hood environments where ambient exceeds 125 °C without derating. |
| Low RDS(on) with TrenchMOS | 7.7 mΩ @ 25 °C reduces I²R losses by >30% vs. planar MOSFETs in same package, improving efficiency in battery-powered modules. |
| Standard-level gate drive | Guaranteed turn-on with 10 V gate-source voltage, eliminating need for charge pumps in 12 V systems. |
| High avalanche energy rating | 560 mJ unclamped EAS allows safe operation during inductive load interruption without snubber circuits. |
Applications
| Engine Control Module (ECM) Fuel Injector Driver | Automotive HVAC Blower Motor Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N4F7AG | 40 V VDS, 220 A ID, 1.4 mΩ RDS(on) - lower voltage, higher current, smaller DFN package. | Designed for 12 V battery management ICs; lacks AEC-Q101 qualification and 75 V rating. | Select only for 12 V systems with strict space constraints and no transient overvoltage risk. |
| IRF1404ZPBF | 40 V VDS, 195 A ID, 3.8 mΩ RDS(on) - legacy planar MOSFET, TO-220 package, no automotive qualification. | Higher RDS(on) drift with temperature; no avalanche rating specified; unsuitable for AEC-compliant designs. | Use only in non-automotive industrial prototypes where cost outweighs reliability and thermal performance. |
Compared with STL220N4F7AG and IRF1404ZPBF, BUK7609-75A uniquely combines 75 V rating, AEC-Q101 compliance, 175 °C operation, and 560 mJ avalanche ruggedness-making it the sole choice for production automotive power switching above 40 V.

FAQ
Is BUK7609-75A,118 suitable for high-frequency PWM switching above 100 kHz?
No-it is optimized for medium-frequency switching (≤50 kHz) in automotive power applications. Its 5068 pF Ciss and 107 ns rise time result in higher switching losses at >100 kHz; use dedicated high-speed MOSFETs like Nexperia's PMGD280UN for such cases.
Can BUK7609-75A,118 be used in high-side configuration with 12 V gate drive?
Yes-its standard-level gate drive requirement (10 V) and 20 V max VGS allow direct use with 12 V supply when paired with a floating gate driver (e.g., Texas Instruments UCC27211). No level-shifting is needed for 12 V rail operation.
What is the minimum PCB copper area required for thermal performance at full 75 A rating?
To sustain 75 A continuous current at Tmb = 25 °C, the mounting base must be soldered to ≥100 mm² of 2 oz copper on an inner layer, with thermal vias to internal planes. Without this, derating to ≤45 A is required per Figure 1.
Does BUK7609-75A,118 include integrated gate protection?
No-it has no built-in gate Zener or ESD protection diode. External 15 V gate clamp (e.g., BZX84-C15) and series gate resistor (≥10 Ω) are required to limit VGS to ±20 V and suppress ringing during fast switching.
