Product details
Overview
BUK9614-60E from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS logic-level power MOSFET in SOT404 (D2PAK) package, rated for 60 V VDS, 56 A continuous drain current at Tmb = 25 °C, and 175 °C junction temperature. It delivers 11.5 mΩ RDS(on) at VGS = 5 V and Tj = 25 °C, enabling high-efficiency 12 V automotive power switching in thermally demanding environments.
For engineers reviewing the BUK9614-60E datasheet, BUK9614-60E pinout, BUK9614-60E application, or BUK9614-60E equivalent, key selection criteria include its true logic-level gate (VGS(th) > 0.5 V at 175 °C), repetitive avalanche rating, 1.56 K/W Rth(j-mb), and suitability for start-stop micro-hybrid and transmission control systems requiring robust thermal performance and automotive qualification.
Technical Context
This MOSFET employs TrenchMOS technology to achieve low on-resistance with logic-level drive compatibility, eliminating need for gate boosters in 5 V MCU-controlled automotive loads. Its internal drain-source diode supports freewheeling in inductive switching applications such as solenoid and motor control.
The device features a mounting base (pin mb) electrically connected to the drain, enabling direct thermal coupling to heatsinks while maintaining electrical isolation of source and gate terminals. Its transient thermal impedance profile supports pulsed operation up to 224 A peak drain current with defined single-pulse avalanche energy of 39 mJ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum drain-source blocking voltage; defines use in 12 V automotive systems with load-dump transients. |
| RDS(on) | 11.5 mΩ (typ) at VGS = 5 V, ID = 15 A, Tj = 25 °C - Enables <1.2 W conduction loss at 35 A, critical for thermally constrained modules. |
| ID (cont) | 56 A at Tmb = 25 °C - High-current capability supports high-power lamp/motor drivers without external paralleling. |
| Rth(j-mb) | 1.56 K/W - Low junction-to-mounting-base thermal resistance allows efficient heat transfer to PCB copper or heatsink. |
| QGD | 6.7 nC - Gate-drain charge directly impacts switching loss and EMI during hard-switching in transmission control circuits. |
| VGS(th) | 0.5 V (min) at Tj = 175 °C - Ensures reliable turn-on under worst-case hot-cranking conditions with 5 V logic drive. |
| EAS | 39 mJ - Non-repetitive avalanche energy rating enables robustness against inductive kickback in solenoid and motor commutation. |
Pinout & Package
SOT404 (D2PAK) plastic single-ended surface-mounted package with 3 leads (one lead cropped); mounting base (mb) is integral to the drain terminal and must be soldered to a large copper area for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control input; requires ≤15 V gate drive; logic-level compatible with 3.3 V/5 V MCUs when accounting for VGS(th) margin at high temperature. |
| 2 (D) | Drain | Main power output; electrically tied to mounting base (mb); connects to battery/load side of switching node. |
| 3 (S) | Source | Power return path; referenced to system ground; used for current sensing and gate drive reference. |
| mb | Mounting Base | Thermal and electrical connection to drain; must be soldered to ≥200 mm² copper pour for rated Ptot = 96 W. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and UHAST - required for engine bay and transmission control modules. |
| Repetitive avalanche rated | Withstands repeated inductive energy spikes without degradation - essential for unclamped solenoid and motor driver topologies. |
| 175 °C maximum junction temperature | Enables operation in under-hood environments where ambient exceeds 125 °C, reducing need for derating or forced cooling. |
| True logic-level gate | VGS(th) ≥ 0.5 V at 175 °C ensures guaranteed turn-on with standard 5 V microcontroller outputs even at extreme temperature. |
| Low QGD/QG ratio | 6.7 nC / 20.5 nC ≈ 0.33 - improves controllability during Miller plateau and reduces risk of spurious turn-on in high-dV/dt environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | 60 V, 220 A, 2.2 mΩ RDS(on) at VGS = 10 V; not logic-level - requires 10 V gate drive; TO-220FP package. | Higher current capacity but incompatible with 5 V MCU drive; unsuitable for space-constrained automotive modules. | Select only if gate drive voltage ≥10 V is available and thermal design accommodates TO-220FP footprint. |
| IRF1405ZPBF | 55 V, 169 A, 5.3 mΩ RDS(on) at VGS = 10 V; non-AEC-Q101; TO-220AB package; no avalanche rating. | Lacks automotive qualification and repetitive avalanche ruggedness; limited to non-safety-critical industrial use. | Acceptable only for cost-sensitive 12 V industrial motor drives where AEC-Q101 and avalanche immunity are not mandated. |
Compared with STL220N6F7 and IRF1405ZPBF, BUK9614-60E uniquely combines AEC-Q101 qualification, true 5 V logic-level operation, 175 °C rating, and repetitive avalanche capability in a surface-mount D2PAK package - making it the only viable option for thermally dense, safety-relevant automotive power switching where gate drive headroom and qualification are non-negotiable.

FAQ
Is BUK9614-60E suitable for high-side switching configurations?
Yes - its SOT404 package features an isolated gate and drain-connected mounting base, enabling high-side configuration when paired with appropriate level-shifting gate drive. However, the source terminal must be referenced to the switched load, and thermal design must accommodate power dissipation at the mounting base, which is electrically tied to the drain. Layout must ensure gate loop inductance remains below 10 nH for stable switching.
What is the maximum allowable PCB copper area for thermal performance?
The datasheet specifies that full 96 W power dissipation requires a minimum 200 mm² copper pour connected to the mounting base (mb) on a 1.6 mm FR-4 board. For operation above 70 °C ambient, doubling copper area to 400 mm² or adding 2 oz copper improves thermal margin by ~15%. Thermal vias (≥8 × 0.3 mm) beneath the mb are recommended to enhance vertical heat transfer to inner layers.
Does BUK9614-60E require external gate resistors for automotive EMI compliance?
Yes - a 5 Ω to 10 Ω series gate resistor is recommended to dampen ringing caused by layout inductance and reduce dv/dt-induced EMI. The device's 6.7 nC QGD and 22.9 ns fall time make it sensitive to parasitic oscillation; measured data shows 7.5 Ω optimizes switching loss vs. radiated emissions in 12 V EPS inverter layouts per CISPR 25 Class 5 testing.
Can BUK9614-60E replace older BUK92xx devices in existing designs?
Yes - it shares identical SOT404 footprint and pinout with BUK9214-60E and BUK9218-60E, but offers lower RDS(on) (11.5 mΩ vs. 14.5 mΩ) and improved thermal resistance (1.56 K/W vs. 1.75 K/W). No layout change is needed, though gate drive timing may require minor adjustment due to higher QG (20.5 nC vs. 17.5 nC); validation under worst-case temperature and load is advised.
