Product details
Overview
BUK7226-75A/C1,118 from Nexperia is a standard-level N-channel TrenchMOS FET in DPAK (SOT428) package, rated for 75 V drain-source voltage, 45 A continuous drain current at 25 °C mounting base temperature, and 175 °C junction temperature. It features 22 mΩ typical RDS(on) at VGS = 10 V and ID = 25 A, 215 mJ non-repetitive avalanche energy, and AEC-Q101 qualification for automotive critical systems.
For engineers reviewing the BUK7226-75A/C1,118 datasheet, BUK7226-75A/C1,118 pinout, BUK7226-75A/C1,118 application, or BUK7226-75A/C1,118 equivalent, this page delivers verified electrical specs, thermal resistance (Rth(j-mb) = 1 K/W), gate charge (QG(tot) = 48 nC), safe operating area limits, and automotive-grade reliability data - all confirmed from Nexperia's official product data sheet Rev. 02 (22 February 2008).
Technical Context
This device uses Nexperia's General Purpose Automotive (GPA) TrenchMOS technology to deliver low on-state resistance with standard-level gate drive compatibility (VGS(th) = 2–4 V typ). Its 1 K/W junction-to-mounting-base thermal resistance enables high-power switching without external heatsink under moderate PCB copper area.
The FET supports unclamped inductive switching with 215 mJ single-pulse avalanche ruggedness and exhibits fast switching performance: td(on) = 14 ns, tr = 66 ns, QGD = 17 nC, and Ciss = 1789–2385 pF - optimized for 12 V, 24 V, and 42 V automotive load control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 75 V maximum - supports operation across 12 V, 24 V, and 42 V automotive battery architectures with margin. |
| ID (continuous) | 45 A at Tmb = 25 °C - capped by bondwire limit, not silicon capability; derates to 38 A at 100 °C mounting base. |
| RDS(on) | 22–26 mΩ typ at VGS = 10 V, ID = 25 A, Tj = 25 °C - enables <1.4 W conduction loss at 25 A. |
| EDS(AL)S | 215 mJ non-repetitive avalanche energy - withstands unclamped inductive turn-off events in motor/solenoid drives. |
| Rth(j-mb) | 1 K/W - allows efficient heat transfer to PCB copper or heatsink via mounting base (drain-connected tab). |
| QG(tot) | 48 nC - determines gate driver power requirement and switching speed in PWM applications. |
| Tj max | 175 °C - qualified for extended automotive ambient conditions including engine bay placement. |
Pinout & Package
Package: DPAK (SOT428), 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 ≥10 V for full enhancement; VGS rating ±20 V. |
| 2 (D) | Drain | Main high-side switching node; internally bonded to mounting base for thermal and electrical connection. |
| 3 (S) | Source | Return path for load current; referenced to system ground in low-side configurations. |
| Mounting base (mb) | Drain extension / thermal pad | Electrically tied to drain; must be soldered to large copper pour for thermal management per Rth(j-mb) = 1 K/W spec. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive safety-critical applications including engine control, body electronics, and ADAS power stages. |
| 175 °C junction rating | Enables reliable operation in high-ambient environments such as under-hood modules without derating penalties. |
| Standard-level gate drive | Operates fully enhanced with 10 V gate drive - compatible with common microcontroller GPIOs and automotive logic-level drivers. |
| Low RDS(on) × QG figure of merit | ~1.1 μΩ·nC - balances conduction efficiency and switching loss for medium-frequency (<100 kHz) power control. |
| Integrated source-drain diode | VSD = 0.85–1.2 V at IS = 25 A - provides freewheeling path in inductive loads without external diode. |

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 |
|---|---|---|---|
| STL220N4F7AG | 40 V VDS, 220 A ID, TO-263 package, 1.6 mΩ RDS(on); higher current, lower voltage, larger footprint. | Targeted at 12 V high-current inverters and starter relays - not suitable for 24/42 V systems. | Select only if system voltage ≤16 V and board space allows TO-263; BUK7226-75A/C1,118 remains optimal for 24/42 V BCM/fan use cases. |
| ON Semiconductor NTMFS5C673NL | 60 V VDS, 100 A ID, PowerTrench® 5x6 mm SO-8FL, 3.1 mΩ RDS(on); lower RDS(on) but lower voltage rating. | Designed for compact 12 V server/industrial SMPS - lacks AEC-Q101 qualification and 175 °C rating. | Use only in non-automotive industrial applications requiring smaller footprint; BUK7226-75A/C1,118 is required where automotive qualification and 75 V margin are mandatory. |
Compared with STL220N4F7AG and NTMFS5C673NL, the BUK7226-75A/C1,118 uniquely combines 75 V rating, AEC-Q101 qualification, 175 °C operation, and DPAK thermal performance - making it the only validated option for 24/42 V automotive load switching where voltage margin, reliability, and thermal design simplicity are jointly critical.

FAQ
What is the maximum continuous drain current rating for BUK7226-75A/C1,118?
The BUK7226-75A/C1,118 has a maximum continuous drain current of 45 A at mounting base temperature (Tmb) = 25 °C, limited by bondwire capacity-not silicon capability. At Tmb = 100 °C, the rating drops to 38 A per Figure 1 in the official datasheet. Derating must follow the normalized power dissipation curve in Figure 2.
Is BUK7226-75A/C1,118 qualified for automotive applications?
Yes, the BUK7226-75A/C1,118 is AEC-Q101 qualified and designed to the appropriate automotive standard for use in critical systems. It is rated for junction temperatures up to 175 °C and tested for reliability under automotive environmental stress conditions including thermal cycling, humidity, and vibration.
What is the thermal resistance from junction to mounting base for BUK7226-75A/C1,118?
The BUK7226-75A/C1,118 has a thermal resistance Rth(j-mb) of 1 K/W from junction to mounting base, as specified in Table 5 of the datasheet. This value assumes proper soldering of the mounting base (drain-connected tab) to a minimum footprint FR4 PCB copper area, enabling efficient heat transfer without additional heatsinks.
Does BUK7226-75A/C1,118 include an integrated body diode?
Yes, the BUK7226-75A/C1,118 integrates a source-drain diode with forward voltage VSD = 0.85–1.2 V at IS = 25 A and Tj = 25 °C (Table 6). This diode supports freewheeling in inductive loads and contributes to the device's avalanche ruggedness specification of 215 mJ.
What gate voltage is required to fully enhance BUK7226-75A/C1,118?
The BUK7226-75A/C1,118 is a standard-level MOSFET requiring VGS = 10 V for full enhancement. Its gate threshold voltage VGS(th) ranges from 2–4 V at Tj = 25 °C (Table 6), but RDS(on) is specified at 10 V. Operation below 10 V increases conduction losses significantly due to higher RDS(on).
