Product details
Overview
BUK653R4-40C from Nexperia is an N-channel TrenchMOS intermediate-level power MOSFET in TO-220AB (SOT78A) package, rated for 40 V VDS, 100 A continuous drain current at Tmb = 25 °C, and 3.05 mΩ typical RDS(on) at VGS = 10 V and Tj = 25 °C. It serves as a high-current, thermally robust switching element in automotive power control circuits.
For engineers reviewing the BUK653R4-40C datasheet, BUK653R4-40C pinout, BUK653R4-40C application, or BUK653R4-40C equivalent, key selection considerations include its AEC Q101 qualification, 175 °C junction rating, avalanche energy capability (368 mJ), gate drive compatibility with standard and logic-level sources, and thermal resistance of 0.74 K/W from junction to mounting base.
Technical Context
This device uses advanced TrenchMOS technology to achieve low on-resistance and high avalanche ruggedness. Its gate threshold voltage ranges from 1.8 V to 2.8 V at 25 °C, enabling reliable turn-on with both 5 V and 10 V gate drivers while maintaining stable operation up to 175 °C junction temperature.
The internal structure supports unclamped inductive switching with non-repetitive avalanche energy of 368 mJ under specified conditions (ID = 100 A, Vsup ≤ 40 V). Dynamic parameters include 125 nC total gate charge and 42 nC gate-drain charge, defining switching speed and driver requirements in high-frequency power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V maximum - defines safe blocking voltage in 12 V automotive systems with load dump transients. |
| ID (continuous) | 100 A at Tmb = 25 °C - enables high-power motor and solenoid control without external parallel devices. |
| RDS(on) | 3.05 mΩ typ @ VGS = 10 V, Tj = 25 °C - minimizes conduction loss and heatsink requirements in thermally constrained designs. |
| EAS | 368 mJ non-repetitive avalanche energy - supports robust operation during inductive turn-off without snubbers in transmission or EPS systems. |
| Tj max | 175 °C - allows sustained operation in under-hood environments where ambient temperatures exceed 105 °C. |
| Rth(j-mb) | 0.74 K/W - enables efficient heat transfer to external heatsinks, critical for high-duty-cycle automotive switching. |
| VGS(th) | 1.8–2.8 V @ Tj = 25 °C - ensures compatibility with both 3.3 V logic-level and 5/10 V standard gate drivers. |
Pinout & Package
Package: TO-220AB (SOT78A), plastic single-ended package with heatsink-mounted mounting base connected to drain; 3-lead configuration with 1 mounting hole.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; requires ≥10 V for full enhancement; threshold range 1.8–2.8 V enables flexible driver selection. |
| 2 (D) | Drain | Main high-side power path; electrically tied to mounting base for direct heatsink coupling and low-inductance layout. |
| 3 (S) | Source | Power return node; referenced to system ground in low-side switch configurations; carries full load current. |
Key Features
| Feature | Design Value |
|---|---|
| AEC Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per AEC Q101 standards. |
| 175 °C junction rating | Enables uninterrupted operation in engine bay locations where ambient exceeds 105 °C and thermal derating margins are tight. |
| Intermediate gate drive | Operates efficiently with both 5 V logic-level and 10 V standard gate drivers-no level-shifting required in most 12 V vehicle architectures. |
| Low RDS(on) × QG figure of merit | 3.05 mΩ × 125 nC = 381 mΩ·nC - balances conduction and switching losses for high-efficiency PWM control in EPS and transmission modules. |
| Unclamped avalanche ruggedness | 368 mJ energy handling capacity - eliminates need for external clamping diodes in inductive load switching like solenoids and fuel injectors. |

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, 220 A, 1.9 mΩ RDS(on), PowerFLAT 5x6 package - lower RDS(on) but surface-mount only; no mounting base. | Suitable for space-constrained PCBs but lacks TO-220AB heatsink interface; requires thermal vias and copper area instead of bolted heatsink. | Select when board-level thermal management is preferred over mechanical heatsinking and higher current is needed. |
| IRF1404ZPBF | 40 V, 184 A, 3.8 mΩ RDS(on), TO-220AB - higher RDS(on), no AEC Q101 qualification, 175 °C rating not guaranteed. | Acceptable for industrial motor drives but not certified for automotive safety-critical functions like EPS or transmission control. | Select only for non-automotive applications where AEC Q101 is not mandated and higher conduction loss is tolerable. |
Compared with STL220N4F7AG and IRF1404ZPBF, the BUK653R4-40C uniquely combines AEC Q101 qualification, TO-220AB mechanical heatsinking, and optimized RDS(on)/QG balance for thermally demanding 12 V automotive power switching-making it the only drop-in solution for production EPS and start-stop modules requiring validated automotive reliability.

FAQ
What is the maximum continuous drain current rating for BUK653R4-40C?
The BUK653R4-40C supports 100 A continuous drain current at mounting base temperature (Tmb) of 25 °C, limited by package thermal capacity-not silicon capability. At Tmb = 100 °C, it maintains the same 100 A rating due to its robust thermal design and low Rth(j-mb) of 0.74 K/W. Derating curves in Figure 1 confirm this flat current profile up to 100 °C.
Is BUK653R4-40C qualified for automotive use?
Yes, the BUK653R4-40C is fully AEC Q101 qualified and designed for high-performance automotive applications. It meets stress test requirements for temperature cycling, humidity, mechanical shock, and high-temperature operating life. The datasheet explicitly states qualification to AEC Q101 and suitability for 12 V automotive systems, EPS, and transmission control.
What is the gate threshold voltage range of BUK653R4-40C?
The BUK653R4-40C has a gate-source threshold voltage (VGS(th)) of 1.8 V minimum to 2.8 V maximum at Tj = 25 °C and ID = 1 mA. At elevated temperature (Tj = 175 °C), VGS(th) drops to 0.8 V minimum, ensuring stable turn-on behavior across the full automotive temperature range.
Can BUK653R4-40C be driven directly by a 3.3 V microcontroller?
No-while the BUK653R4-40C has a low VGS(th), its RDS(on) rises significantly at VGS < 4.5 V: 4.5–6.0 mΩ at 4.5 V vs. 3.05 mΩ at 10 V. Driving with 3.3 V yields incomplete enhancement and excessive conduction loss. A gate driver or level shifter is required for reliable full-enhancement operation.
What is the thermal resistance from junction to mounting base for BUK653R4-40C?
The BUK653R4-40C has a maximum thermal resistance of 0.74 K/W from junction to mounting base (Rth(j-mb)). This value reflects direct thermal conduction through the drain-connected mounting base to an external heatsink, enabling efficient heat dissipation in high-power automotive applications such as motor control and solenoid drivers.
