Product details
Overview
BUK6E2R0-30C from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS FET in I2PAK (SOT226) package, designed for intermediate-level gate drive in automotive power switching. It delivers 120 A continuous drain current at 25 °C mounting base temperature, 30 V VDS, 1.9 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C, and operates up to 175 °C junction temperature-enabling use in electric power steering and start-stop micro-hybrid systems.
For engineers reviewing the BUK6E2R0-30C datasheet, BUK6E2R0-30C pinout, BUK6E2R0-30C application, or BUK6E2R0-30C equivalent, key selection criteria include its 306 W total power dissipation at Tmb = 25 °C, unclamped avalanche energy of 1.7 J, thermal resistance Rth(j-mb) = 0.49 K/W, and suitability for thermally demanding 12 V automotive subsystems requiring robust MOSFET switching.
Technical Context
This device employs advanced TrenchMOS technology to achieve low on-resistance and high avalanche ruggedness while meeting AEC-Q101 stress testing requirements for automotive reliability. Its gate threshold voltage (VGS(th)) ranges from 1.8 V to 2.8 V at 25 °C, enabling compatibility with standard 5 V and 10 V logic-level gate drivers.
The integrated source-drain diode supports freewheeling in inductive loads, with typical VSD = 0.8–1.2 V at 25 A and reverse recovery time trr = 70 ns. Dynamic parameters-including QG(tot) = 229 nC at VGS = 10 V and Ciss = 11.2–15.0 pF-support precise PWM timing control in motor and solenoid drive circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V maximum drain-source voltage - defines safe operating range in 12 V automotive systems with load dump transients. |
| RDS(on) | 1.9 mΩ typical at VGS = 10 V, ID = 25 A, Tj = 25 °C - enables <1.2 W conduction loss at 50 A, critical for thermal management in compact modules. |
| ID | 120 A continuous drain current at Tmb = 25 °C - supports high-current motor and lamp loads without external heatsinking beyond mounting base. |
| Ptot | 306 W total power dissipation at Tmb = 25 °C - reflects high thermal coupling to PCB or heatsink via metal mounting base. |
| EDS(AL)S | 1.7 J non-repetitive avalanche energy - provides single-event fault tolerance during inductive turn-off without external snubbers. |
| Rth(j-mb) | 0.49 K/W thermal resistance from junction to mounting base - allows direct thermal path design for sustained 175 °C operation in engine bay environments. |
| trr | 70 ns source-drain diode reverse recovery time - minimizes switching losses and EMI in high-frequency PWM control of solenoids and actuators. |
Pinout & Package
Package: I2PAK (SOT226), plastic single-ended package with metal mounting base connected internally to the drain terminal. The package provides low-inductance layout, high thermal conductivity, and mechanical robustness for automotive under-hood mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control input for MOSFET channel activation; requires ≤10 V drive for full enhancement; gate leakage <100 nA at ±20 V. |
| 2 (D) | Drain | Main high-side power terminal; electrically tied to mounting base for thermal and electrical integration into PCB heatsink planes. |
| 3 (S) | Source | Power return path and reference node for gate drive; internal source bond pad inductance LS = 7.5 nH limits high-dI/dt ringing. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and UIS testing-ensures long-term operation in safety-critical power steering and transmission control. |
| 175 °C maximum junction temperature | Enables deployment in high-ambient locations (e.g., near engines or inverters) without derating below rated current at elevated temperatures. |
| Low RDS(on) × QG figure-of-merit | 229 nC total gate charge at 10 V drive with 1.9 mΩ on-resistance - balances switching speed and conduction efficiency for 10–100 kHz motor control. |
| Integrated source-drain diode | Forward voltage VSD = 0.8–1.2 V at 25 A supports freewheeling in brushed DC motors and solenoids without discrete diode addition. |
| Mounting base as drain terminal | Eliminates need for isolated thermal interface; enables direct bolt-down to chassis or heatsink while maintaining electrical connection to drain circuit. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N3LLH6 | 30 V, 220 A, RDS(on) = 1.4 mΩ @ 10 V, PowerFLAT 8x8 package (no mounting base) | Lacks integral mounting base; requires external thermal interface; higher current rating but lower avalanche energy (1.2 J) | Preferred where PCB area is constrained and board-level heatsinking is feasible; not drop-in for I2PAK footprint. |
| IRF1404ZPBF | 40 V, 184 A, RDS(on) = 3.8 mΩ @ 10 V, TO-220AB package; not AEC-Q101 qualified | Higher VDS margin but double RDS(on); no automotive qualification; higher thermal resistance (Rth(j-c) = 0.75 K/W) | Suitable for non-automotive industrial motor drives; unsuitable for safety-critical automotive functions due to missing AEC-Q101 validation. |
Compared with STL220N3LLH6 and IRF1404ZPBF, BUK6E2R0-30C offers optimal balance of automotive qualification, low thermal resistance (0.49 K/W), and proven avalanche ruggedness (1.7 J) in a mechanically robust I2PAK package-making it uniquely suited for thermally aggressive, safety-relevant 12 V power switching where reliability trumps raw current rating.

FAQ
What is the maximum allowable gate-source voltage for BUK6E2R0-30C?
The absolute maximum VGS is ±16 V for DC operation and ±20 V for pulsed conditions per IEC 60134 limiting values. Exceeding these risks permanent gate oxide damage. Gate drive circuits must limit transient overshoot using clamping diodes or resistor-capacitor networks, especially in high-dV/dt automotive environments.
Can BUK6E2R0-30C be used in parallel configurations?
Yes, but only with careful attention to gate drive matching and current sharing. Its positive RDS(on) temperature coefficient (RDS(on) increases with Tj) promotes inherent current balancing. However, layout symmetry, matched gate resistors (<5 Ω), and individual gate routing are required to prevent oscillation and unequal stress between paralleled devices.
Is the mounting base electrically isolated from the drain?
No-the mounting base is internally connected to the drain terminal, as confirmed in Table 2 pinning information and Figure 17 package outline. This design enables direct thermal transfer to heatsinks but requires electrical isolation of the heatsink or PCB copper area from other circuit potentials to avoid short circuits.
What is the recommended PCB layout for optimal thermal performance?
Use ≥100 mm² of 2 oz copper connected directly to the mounting base pad, with ≥4 thermal vias (0.3 mm diameter, filled or plated) per mm² beneath the pad. Avoid routing signal traces under the device. Maintain ≥1.5 mm clearance from adjacent components to ensure free-air convection and minimize thermal coupling in dense automotive ECUs.
