Product details
Overview
BUK754R3-75C from NXP Semiconductors is a standard-level N-channel TrenchMOS FET in TO-220AB (SOT78A) package, rated for 75 V VDS, 100 A continuous drain current at Tmb = 25 °C, and 3.7–4.3 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C. It serves as a high-current power switch in automotive load control circuits including motors, lamps, and solenoids operating at 12 V, 24 V, or 42 V.
For engineers reviewing the BUK754R3-75C datasheet, BUK754R3-75C pinout, BUK754R3-75C application, or BUK754R3-75C equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C junction temperature rating, low on-resistance with standard gate drive, avalanche energy rating of 630 mJ, and thermal resistance of 0.45 K/W from junction to mounting base.
Technical Context
This device uses TrenchMOS technology to achieve low RDS(on) while maintaining robustness under thermally demanding conditions. Its gate threshold voltage ranges from 1 V at Tj = 175 °C to 4.4 V at Tj = −55 °C, enabling stable turn-on across automotive temperature extremes.
The FET features unclamped inductive switching capability with 630 mJ non-repetitive avalanche energy and supports peak drain currents up to 769 A in pulsed operation. Internal drain and source inductances are specified at 3.5–4.5 nH and 7.5 nH respectively, supporting fast switching with controlled ringing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 75 V maximum - supports 42 V automotive systems with ≥75 % safety margin against transients. |
| RDS(on) | 3.7–4.3 mΩ at VGS = 10 V, Tj = 25 °C - enables <1 W conduction loss at 50 A DC load current. |
| ID (continuous) | 100 A at Tmb = 25 °C - defined by package thermal limits, not silicon capability. |
| Ptot | 333 W at Tmb = 25 °C - requires heatsink mounting for sustained high-power operation. |
| Rth(j-mb) | 0.45 K/W - enables efficient heat transfer to external heatsink, critical for automotive under-hood use. |
| EDS(AL)S | 630 mJ non-repetitive avalanche energy - protects against inductive kickback in motor/solenoid switching. |
| VGS(th) | 2–4.4 V typical range (Tj = 25–−55 °C) - ensures reliable turn-on with standard 12 V gate drivers. |
Pinout & Package
Package: TO-220AB (SOT78A), plastic single-ended package with heatsink-mounted mounting base connected to drain terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Standard-level MOSFET control input; accepts 10 V logic-compatible drive for full enhancement. |
| 2 (D) | Drain | Main high-side power path; electrically tied to mounting base for direct heatsink coupling. |
| 3 (S) | Source | Power return node; referenced to system ground in low-side switch configurations. |
| Mounting base (mb) | Drain connection | Integral thermal and electrical path to heatsink; must be isolated from chassis if drain is not grounded. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP110N75F7 | 75 V VDS, 110 A ID, 3.2 mΩ RDS(on), D2PAK package, no AEC-Q101 certification | Higher current rating but lacks automotive qualification; suitable for industrial motor drives only | Select when higher peak current is needed and automotive qualification is not required |
| IRFB4115PBF | 150 V VDS, 110 A ID, 5.2 mΩ RDS(on), TO-220AB, AEC-Q101 compliant | Higher voltage rating increases cost and gate charge; lower RDS(on) not realized due to higher VGS(th) | Choose only if system transient protection requires >75 V rating; otherwise BUK754R3-75C offers better efficiency at 12–42 V |
Compared with STP110N75F7 and IRFB4115PBF, the BUK754R3-75C delivers optimal balance of low on-resistance, automotive qualification, and thermal performance specifically for 12–42 V automotive loads-without over-specifying voltage or sacrificing qualification status.

FAQ
What is the maximum continuous drain current rating for BUK754R3-75C?
The BUK754R3-75C has a maximum continuous drain current of 100 A at mounting base temperature (Tmb) = 25 °C, limited by package thermal dissipation rather than silicon capability. At Tmb = 100 °C, the rating remains 100 A per Figure 1 in the datasheet, reflecting its robust thermal design. This value applies under standard gate drive (VGS = 10 V) and proper heatsinking.
Is BUK754R3-75C qualified for automotive applications?
Yes, the BUK754R3-75C is explicitly qualified to AEC-Q101 standards for use in automotive critical applications. Its design includes 175 °C maximum junction temperature, enhanced package robustness, and rigorous testing for temperature cycling, humidity, and mechanical shock-making it suitable for engine control, body electronics, and ADAS power stages.
What is the thermal resistance from junction to mounting base for BUK754R3-75C?
The BUK754R3-75C has a maximum thermal resistance of 0.45 K/W from junction to mounting base (Rth(j-mb)). This low value enables efficient heat transfer to an external heatsink, which is essential for sustaining high-current operation in thermally demanding automotive environments such as under-hood fan or solenoid drivers.
Does BUK754R3-75C support avalanche operation?
Yes, the BUK754R3-75C is rated for non-repetitive drain-source avalanche energy of 630 mJ under specified test conditions (ID = 100 A, Vsup ≤ 75 V, RGS = 50 Ω, VGS = 10 V, Tj(init) = 25 °C, unclamped). This ruggedness protects against inductive kickback during turn-off in motor, lamp, and solenoid switching applications.
What package type does BUK754R3-75C use, and how is the mounting base connected?
The BUK754R3-75C uses the TO-220AB package (SOT78A), a plastic single-ended package with three leads and a metal mounting base. The mounting base is electrically connected to the drain terminal (Pin 2), enabling direct thermal coupling to a heatsink while also serving as the primary high-current drain path in PCB layouts.
