Product details
Overview
BUK6607-55C,118 from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS FET in D2PAK (SOT404) package, designed for automotive power switching with 55 V VDS, 100 A continuous drain current at Tmb = 25 °C, and 5.5 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C. It supports both logic-level (≥4.5 V) and standard gate drive, operates up to 175 °C junction temperature, and is used in electric power steering, start-stop micro-hybrid systems, and transmission control.
For engineers reviewing the BUK6607-55C,118 datasheet, BUK6607-55C,118 pinout, BUK6607-55C,118 application, or BUK6607-55C,118 equivalent, key selection criteria include avalanche ruggedness (128 mJ), thermal resistance (0.95 K/W j-to-mb), gate charge (82 nC at VGS = 10 V), and automotive qualification status - all critical for high-reliability 12 V/24 V vehicle subsystems.
Technical Context
This device implements a trench-gate MOSFET structure optimized for low RDS(on) and fast switching in thermally constrained automotive environments. Its dual gate-drive compatibility (logic- and standard-level) enables direct interfacing with microcontrollers and dedicated gate drivers without level-shifting circuitry.
The integrated source-drain diode exhibits 0.8–1.2 V forward voltage at 25 A and 48 ns reverse recovery time, supporting synchronous rectification and freewheeling in inductive load control. Avalanche energy rating (128 mJ unclamped) and 175 °C maximum junction temperature ensure robustness under transient overvoltage and high-temperature operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V - Maximum drain-source blocking voltage; defines safe operating range in 24 V automotive systems with load dump transients. |
| RDS(on) | 5.5 mΩ (typ.) at VGS = 10 V, Tj = 25 °C - Enables <1 W conduction loss at 40 A, critical for thermal management in compact ECUs. |
| ID (cont) | 100 A at Tmb = 25 °C - Continuous current capability limited by D2PAK package thermal performance, not die. |
| QG(tot) | 82 nC at VGS = 10 V - Determines gate driver power requirement and switching speed; impacts EMI and efficiency trade-offs. |
| Rth(j-mb) | 0.95 K/W - Junction-to-mounting-base thermal resistance; enables accurate heatsink sizing when mounted on PCB copper or metal-core substrate. |
| EAS | 128 mJ (unclamped) - Non-repetitive avalanche energy; ensures survival during inductive turn-off events without external snubbers. |
| Tj(max) | 175 °C - Maximum junction temperature; supports operation in engine bay locations with minimal derating. |
Pinout & Package
Package: D2PAK (SOT404), plastic single-ended surface-mounted package with 3 leads (one lead cropped); mounting base (mb) is electrically connected to drain and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Controls channel conduction; requires ≤16 V DC gate-source voltage; 82 nC total gate charge dictates driver strength needed. |
| 2 (D) | Drain | Main high-side power terminal; internally bonded to mounting base for low-inductance, high-current path and thermal conduction. |
| 3 (S) | Source | Power return node; referenced for gate drive; internal source inductance (7.5 nH) affects switching waveform integrity. |
| mb | Mounting Base | Electrically tied to drain; provides mechanical attachment and primary thermal interface to heatsink or PCB copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock per AEC standard. |
| Logic- and standard-level gate drive | Turns on fully at VGS ≥ 4.5 V (RDS(on) ≤ 10.2 mΩ), enabling direct MCU GPIO control without external level shifters. |
| 175 °C maximum junction temperature | Supports placement in high-ambient zones (e.g., near engines or inverters) with full electrical specification retention. |
| Low RDS(on) × QG figure of merit | 5.5 mΩ × 82 nC = 451 mΩ·nC - Balances conduction and switching losses for high-efficiency motor/solenoid control. |
| Integrated avalanche ruggedness | 128 mJ unclamped EAS eliminates need for external clamping diodes in inductive load switching applications. |

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, 2.2 mΩ RDS(on), TO-263 package; higher current but larger footprint and no AEC-Q101 documentation in public datasheet. | Targeted at higher-power traction inverters; lacks explicit automotive qualification evidence for safety-critical EPS use. | Select only if >150 A continuous current is required and board space allows TO-263; verify AEC-Q101 compliance via ST's official automotive qualification report. |
| IRF1405PBF | 55 V VDS, 169 A ID, 5.3 mΩ RDS(on), TO-220AB; non-automotive grade, 175 °C Tj, no avalanche rating published. | Suitable for industrial motor drives but not certified for automotive ECU deployment due to missing AEC-Q101 validation. | Acceptable for cost-sensitive non-automotive 12 V systems where qualification traceability is not mandated; avoid in OEM-tier designs. |
Compared with STL220N6F7AG and IRF1405PBF, BUK6607-55C,118 uniquely combines AEC-Q101 certification, D2PAK thermal performance (0.95 K/W), and documented 128 mJ avalanche ruggedness - making it the only drop-in solution for safety-critical automotive power switching where qualification, thermal density, and transient robustness are jointly required.

FAQ
Is BUK6607-55C,118 pin-compatible with other D2PAK MOSFETs?
Yes - it uses standard SOT404 (D2PAK) pinout: Pin 1 = Gate, Pin 2 = Drain (mounting base), Pin 3 = Source. Mechanical and electrical pin mapping matches industry-standard D2PAK footprints, enabling layout reuse across qualified automotive MOSFETs with identical package outline.
What is the maximum gate-source voltage rating for continuous operation?
The absolute maximum DC gate-source voltage is ±16 V per the datasheet limiting values table. Exceeding this risks permanent gate oxide damage. For reliable long-term operation, design gate drive circuits to clamp VGS within ±12 V, especially during transients or hot-plug events.
Does BUK6607-55C,118 require a gate resistor for automotive PWM applications?
Yes - a series gate resistor (typically 5–22 Ω) is required to damp ringing caused by LS (7.5 nH) and LD (3.5 nH) parasitics, and to limit peak gate current during fast switching. Without it, overshoot exceeding ±20 V VGS pulses may occur, risking gate oxide degradation over time.
Can BUK6607-55C,118 be used in synchronous rectification topologies?
Yes - its integrated source-drain diode has 48 ns trr and 86 nC Qr, enabling efficient synchronous rectification in 12 V/24 V DC-DC converters. However, body diode conduction should be minimized via precise timing control to avoid reverse recovery losses and thermal stress.
