Product details
Overview
BUK7623-75A,118 from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS FET in D2PAK (SOT404) package, designed for automotive power switching. It delivers 53 A continuous drain current at 25 °C mounting base temperature, 49 mΩ RDS(on) at 175 °C junction temperature, and 75 V drain-source voltage rating - enabling robust 12 V/24 V load control in engine management, lighting, and solenoid drive circuits.
For engineers reviewing the BUK7623-75A datasheet, BUK7623-75A pinout, BUK7623-75A application, or BUK7623-75A equivalent, this device supports thermally demanding automotive environments up to 175 °C junction temperature, requires standard-level 10 V gate drive, and provides unclamped avalanche energy handling of 120 mJ - critical for inductive load switching reliability.
Technical Context
This standard-level MOSFET uses TrenchMOS technology to achieve low conduction losses while maintaining compatibility with conventional 10 V gate drivers. Its 1.1 K/W junction-to-mounting-base thermal resistance enables high-power operation without active cooling in constrained automotive PCB layouts.
The device integrates a robust body diode with 0.85–1.2 V forward voltage at 25 A and 53 ns reverse recovery time, supporting freewheeling in motor and relay circuits. Avalanche ruggedness is characterized under unclamped inductive switching conditions (ID = 49 A, Vsup ≤ 75 V, RGS = 50 Ω), confirming suitability for non-clamped inductive load interruption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 75 V maximum - supports full-range 42 V automotive systems with margin against load-dump transients. |
| ID (continuous) | 53 A at Tmb = 25 °C - enables high-current DC loads like radiator fans and fuel pumps without external heatsinking. |
| RDS(on) | 17–23 mΩ at 25 °C / 49 mΩ at 175 °C - ensures low conduction loss across full automotive temperature range. |
| EAS | 120 mJ unclamped avalanche energy - sustains single-pulse inductive energy without failure during solenoid or motor turn-off. |
| Tj max | 175 °C - qualified for under-hood applications including transmission control and engine ECU power stages. |
| QG | ~50 nC typical (from Fig 10) - compatible with standard gate drivers without requiring high-current buffer stages. |
| Ciss | 1789–2385 pF - defines gate drive power requirement and influences switching speed in PWM applications. |
Pinout & Package
Package: D2PAK (SOT404), plastic surface-mounted package with isolated mounting base connected to drain terminal. Dimensions per IEC JEDEC outline: 15.8 × 10.3 × 4.5 mm (L × W × H), with 2.54 mm lead pitch and integral drain pad for thermal conduction to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Controls channel conduction; requires 10 V drive for full enhancement; gate leakage <100 nA at ±20 V. |
| 2 (D) | Drain | Main high-side current path; electrically tied to mounting base for direct thermal coupling to heatsink or PCB plane. |
| 3 (S) | Source | Return path for load current; referenced for gate drive; internal source inductance 7.5 nH affects switching ringing. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive safety-critical functions including engine control and braking modules. |
| Low RDS(on) over temperature | 49 mΩ at 175 °C ensures stable on-state loss in hot under-hood environments without derating. |
| Standard-level gate drive | Full enhancement at VGS = 10 V eliminates need for level-shifters or charge pumps in 12 V/24 V systems. |
| High avalanche energy rating | 120 mJ unclamped EAS allows reliable operation in inductive switching without external snubbers. |
| Thermal performance | 1.1 K/W Rth(j-mb) enables >100 W dissipation with minimal ΔT between junction and heatsink. |

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 |
|---|---|---|---|
| STP110N75F7 | 75 V VDS, 110 A ID, 5.8 mΩ RDS(on) @ 25 °C, but only rated to 150 °C Tj and not AEC-Q101 qualified. | Higher current capacity suits larger motors, but lacks automotive qualification and high-temp stability. | Select when higher peak current is needed and AEC-Q101 is not mandated; verify thermal design for 150 °C limit. |
| IRFB4115PBF | 150 V VDS, 115 A ID, 7.5 mΩ RDS(on) @ 25 °C, AEC-Q101 qualified, but larger TO-220AB package increases board area and thermal impedance. | Better voltage margin for 48 V mild-hybrid systems, but lower power density and higher Rth(j-a). | Prefer for 48 V architectures or where TO-220 mechanical mounting is required; avoid if D2PAK footprint and thermal performance are critical. |
Compared with STP110N75F7 and IRFB4115PBF, BUK7623-75A uniquely balances AEC-Q101 compliance, 175 °C operation, D2PAK thermal efficiency, and standard gate drive - making it optimal for space-constrained, high-reliability 12 V/24 V automotive power stages.

FAQ
Is BUK7623-75A,118 suitable for 48 V mild-hybrid automotive systems?
No - its 75 V VDS rating provides sufficient margin for 12 V and 24 V systems and transient spikes up to ISO 7637-2 Pulse 5a (up to 60 V), but does not meet the 80–100 V minimum requirement for sustained 48 V bus operation or load-dump events in mild-hybrid architectures.
What is the recommended PCB layout for optimal thermal performance?
Use ≥200 mm² of 2 oz copper connected directly to the mounting base (drain terminal) with ≥4 thermal vias (0.3 mm diameter, spaced ≤2 mm apart) to inner-layer ground or dedicated thermal planes. Maintain ≥1.5 mm clearance from adjacent components to prevent localized heating and ensure airflow over the exposed drain pad.
Does BUK7623-75A,118 require a gate resistor for automotive PWM applications?
Yes - a 10 Ω external gate resistor is specified in the datasheet for switching characterization (td(on)/td(off)). This value suppresses gate oscillation, controls dV/dt to reduce EMI, and limits peak gate current to <1 A during 10 V transitions, protecting standard MCU GPIO or gate driver ICs.
Can the internal body diode be used for freewheeling in motor H-bridge configurations?
Yes - the source-drain diode has 0.85–1.2 V VSD at 25 A and 53 ns trr, enabling efficient freewheeling in low-frequency (<5 kHz) brushed DC motor drives. However, for high-frequency or regenerative braking, an external Schottky diode is recommended due to lower forward drop and faster recovery.
