Product details
Overview
BUK72150-55A,118 from Nexperia is a standard-level N-channel TrenchMOS FET in DPAK (SOT428) package, rated for 55 V drain-source voltage, 11 A continuous drain current at 25 °C mounting base temperature, and 36 W total power dissipation. It delivers 127 mΩ typical RDS(on) at VGS = 10 V and Tj = 25 °C, with AEC-Q101 qualification and 175 °C junction rating for automotive load switching.
For engineers reviewing the BUK72150-55A,118 datasheet, BUK72150-55A,118 pinout, BUK72150-55A,118 application, or BUK72150-55A,118 equivalent, key selection criteria include its 55 V VDS, thermally robust DPAK mounting base, gate compatibility with standard 10 V drive, and avalanche energy rating of 16 mJ under unclamped conditions.
Technical Context
This MOSFET employs TrenchMOS technology to achieve low on-resistance while maintaining stable threshold voltage across temperature (VGS(th) = 2–4 V at 25 °C, down to 1 V at 175 °C). Its gate charge profile-QG(tot) = 5.5 nC, QGD = 2.7 nC-supports fast switching with minimal drive loss in 12 V/24 V DC systems.
The device features integrated source-drain diode with 1.25–1.5 V forward voltage at 10 A and 32 ns reverse recovery time, enabling efficient freewheeling in inductive loads. Thermal resistance from junction to mounting base is 4.1 K/W, allowing direct heatsinking via the exposed drain pad (pin 2 and mounting base).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V maximum - supports 24 V automotive systems with ≥2× voltage margin against transients. |
| ID (continuous) | 11 A at Tmb = 25 °C - enables direct control of high-current solenoids, lamps, and small motors without external heatsink. |
| RDS(on) | 127 mΩ typ @ VGS = 10 V, ID = 5 A, Tj = 25 °C - limits conduction loss to ≤7.1 W at 10 A, reducing thermal stress. |
| EAS | 16 mJ non-repetitive avalanche energy - sustains unclamped inductive turn-off events common in motor and relay drivers. |
| Tj max | 175 °C - ensures reliable operation in engine bay and under-hood environments per AEC-Q101 requirements. |
| QGD | 2.7 nC - minimizes Miller-induced switching delay and improves controllability during hard commutation. |
| Rth(j-mb) | 4.1 K/W - enables efficient heat transfer to PCB copper or external heatsink via the mounted base (drain-connected). |
Pinout & Package
Package: SOT428 (DPAK), plastic single-ended surface-mounted package with 3 leads (lead 2 cropped); mounting base electrically connected to drain for thermal and electrical integration.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 | Drain (D) / Mounting Base | Main power output terminal and thermal interface; electrically tied to exposed copper pad for low-inductance, low-thermal-resistance heatsinking. |
| 3 | Source (S) | Power return path; referenced to system ground in low-side switch configuration; carries full load current and reverse recovery current. |
Key Features
| Feature | Design Value |

FAQ
Is BUK72150-55A,118 suitable for high-frequency PWM applications?
Yes-its 2.7 nC gate-drain charge and 5.5 nC total gate charge enable clean, fast switching up to 100 kHz in motor and LED drivers. Measured turn-on delay is 3 ns and fall time is 10 ns with 5.6 Ω external gate resistor, minimizing switching losses in thermally constrained layouts.
What is the role of the mounting base (pin 2) in thermal management?
The mounting base is electrically connected to the drain and serves as the primary thermal interface. With Rth(j-mb) = 4.1 K/W, it transfers heat directly to PCB copper pours or external heatsinks-eliminating reliance on lead-frame conduction and improving thermal stability over TO-220 alternatives.
Does BUK72150-55A,118 require a gate resistor for safe operation?
A gate resistor is recommended to control dV/dt and prevent oscillation. Typical values range from 5.6 Ω to 22 Ω depending on drive strength and layout parasitics. The device's 2.5 nH internal drain inductance and 7.5 nH source inductance make controlled gate drive essential for EMI reduction in automotive environments.
Can BUK72150-55A,118 replace mechanical relays in automotive applications?
Yes-it is widely used as a solid-state relay replacement for loads up to 11 A, offering silent operation, longer lifetime, and immunity to contact wear. Its 16 mJ avalanche rating handles inductive kickback from coils and solenoids without external suppression components, meeting ISO 7637-2 pulse test requirements when properly laid out.
