Product details
Overview
BUK7610-55AL,118 from Nexperia is an N-channel enhancement-mode TrenchMOS FET in D2PAK (SOT404) package, optimized for linear-mode operation in automotive systems. It delivers 75 A continuous drain current at 25 °C mounting base temperature, 8.5 mΩ typical RDS(on) at VGS = 10 V and Tj = 25 °C, and is AEC-Q101 qualified for critical automotive applications including DC motor control and clamped inductive switching.
For engineers reviewing the BUK7610-55AL,118 datasheet, BUK7610-55AL,118 pinout, BUK7610-55AL,118 application, or BUK7610-55AL,118 equivalent, key selection criteria include linear-mode thermal stability, avalanche ruggedness (1.1 J non-repetitive), 55 V VDS rating, and junction-to-mounting-base thermal resistance of 0.25 K/W - all validated for 175 °C operation.
Technical Context
This device uses Nexperia's General-Purpose Automotive (GPA) TrenchMOS technology to enable stable linear-mode conduction with low RDS(on) drift over temperature. Its gate threshold voltage ranges from 1 V (Tj = 175 °C) to 4.4 V (Tj = −55 °C), supporting robust turn-on margin across automotive ambient extremes.
The integrated source-drain diode exhibits 0.85 V forward voltage at 25 A and 25 °C, with 73 ns reverse recovery time and 430 nC recovered charge - enabling efficient unclamped inductive energy handling. Avalanche capability is rated at 1.1 J (non-repetitive) under defined test conditions (ID = 75 A, Vsup ≤ 55 V, RGS = 50 Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V maximum drain-source voltage - defines safe blocking capability for 12 V/24 V automotive bus transients. |
| RDS(on) | 8.5 mΩ typical at VGS = 10 V, ID = 25 A, Tj = 25 °C - enables low conduction loss in high-current power switches. |
| ID (cont.) | 75 A maximum continuous drain current at Tmb = 25 °C - limited by package thermal capacity, not die capability. |
| EAS | 1.1 J non-repetitive avalanche energy - supports single-event inductive load switching without failure. |
| Rth(j-mb) | 0.25 K/W typical junction-to-mounting-base thermal resistance - enables direct heatsink coupling for high-power linear operation. |
| QG(tot) | 124 nC total gate charge - determines driver strength requirement for fast switching in PWM or soft-start circuits. |
| VGS(th) | 2–4 V typical gate threshold voltage at 25 °C - ensures reliable turn-on with standard 5 V or 3.3 V logic-level drivers. |
Pinout & Package
Package: D2PAK (SOT404), plastic single-ended surface-mounted package with 3 leads (one lead cropped); mounting base electrically connected to drain.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Controls channel conduction; requires ≥10 V drive for full RDS(on) specification; max ±20 V rating. |
| 2 (D) | Drain | Main high-side current path; internally bonded to mounting base for low-inductance thermal/power path. |
| 3 (S) | Source | Reference node for gate drive; carries full load current; internal source inductance = 7.5 nH. |
| Mounting Base (mb) | Drain Extension | Electrically tied to drain pin; provides primary thermal interface to heatsink; critical for linear-mode thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive safety-critical applications per stress test requirements (HTOL, TC, UHAST, etc.). |
| 175 °C rated junction temperature | Enables operation in engine bay or transmission control environments without derating at peak ambient. |
| Stable linear-mode operation | Optimized TrenchMOS cell design minimizes RDS(on) thermal runaway during analog conduction. |
| Low RDS(on) × QG product | 124 nC × 8.5 mΩ = 1.05 μΩ·nC - balances switching loss and conduction loss in mixed-mode applications. |
| Integrated source-drain diode | 0.85 V VSD at 25 A supports freewheeling in H-bridge motor drives without external diode. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | 60 V VDS, 2.2 mΩ RDS(on) @ 10 V, but only AEC-Q100 qualified (not Q101); higher gate charge (190 nC). | Limited to non-safety-critical automotive functions due to lower qualification level; less suitable for linear mode. | Select when ultra-low RDS(on) dominates over avalanche ruggedness and linear stability. |
| IRFB4115PBF | 55 V VDS, 10.5 mΩ RDS(on), no AEC qualification; TO-220 package with higher Rth(j-a) (1.2 K/W). | Not suitable for automotive production; requires larger heatsink area and lacks automotive reliability validation. | Consider only for industrial prototypes where qualification is not required and board space permits TO-220 footprint. |
Compared with STL220N6F7 and IRFB4115PBF, BUK7610-55AL,118 uniquely combines AEC-Q101 qualification, 175 °C rating, and verified linear-mode stability - making it the only option qualified for safety-critical automotive linear switching where thermal runaway must be avoided.

FAQ
Is BUK7610-55AL,118 suitable for linear-mode operation?
Yes. It is explicitly designed and characterized for stable linear-mode operation, with data sheet figures showing RDS(on) vs. temperature, safe operating area (SOA) curves up to DC, and thermal resistance optimized for mounting base cooling. Its GPA TrenchMOS process minimizes thermal runaway risk.
What is the maximum continuous drain current at 100 °C mounting base temperature?
The datasheet specifies 75 A continuous drain current at both Tmb = 25 °C and Tmb = 100 °C - this reflects package-limited current, not die-limited, and remains constant across that range per Figure 4 and Table 4 limiting values.
Does the mounting base require electrical isolation from the heatsink?
Yes. The mounting base is electrically connected to the drain terminal (Pin 2), so if the heatsink is grounded or at a different potential, electrical isolation (e.g., mica washer or insulating pad) is mandatory to prevent short circuits and ensure functional safety compliance.
How does its avalanche ruggedness compare to standard industrial MOSFETs?
With 1.1 J non-repetitive EAS under defined test conditions (ID = 75 A, Vsup ≤ 55 V), BUK7610-55AL,118 exceeds most standard industrial MOSFETs in single-pulse energy handling - a result of AEC-Q101 qualification requirements and dedicated avalanche testing per automotive standards.
