Product details

Overview

BUK9616-75B,118 from Nexperia is a logic-level N-channel TrenchMOS FET in D2PAK (SOT404) package, rated for 75 V drain-source voltage, 67 A continuous drain current at 25 °C mounting base temperature, and 157 W total power dissipation. It delivers 12 mΩ R_DS(on) at V_GS = 10 V and 25 °C, supports automotive AEC-Q101 qualification, and operates up to 175 °C junction temperature for engine bay and transmission control applications.

For engineers reviewing the BUK9616-75B,118 datasheet, BUK9616-75B,118 pinout, BUK9616-75B,118 application, or BUK9616-75B,118 equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) typ. 1.5 V), low R_DS(on) at 5 V gate drive (14 mΩ), avalanche energy rating (140 mJ), thermal resistance to mounting base (0.95 K/W), and automotive-grade reliability validation.

Technical Context

This device implements a trench-gate MOSFET architecture optimized for low conduction loss and fast switching in high-current DC loads. Its gate threshold voltage ranges from 0.5 V at 175 °C to 2.3 V at –55 °C, enabling robust turn-on across automotive temperature extremes while maintaining sub-1 µA gate leakage at ±15 V.

The integrated source-drain diode exhibits 0.85 V forward voltage at 25 A and 25 °C, with 96 ns reverse recovery time and 138 nC recovered charge-critical for inductive load commutation in motor and solenoid drivers. Dynamic parameters include 14 nC Q_GD, 35 nC Q_G(tot), and 3026 pF C_iss, supporting efficient gate driving in 12 V/24 V systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	75 V maximum - supports 42 V automotive bus transients per ISO 7637-2 without clamping.
I_D (continuous)	67 A at T_mb = 25 °C - enables direct replacement of mechanical relays in high-current body electronics.
R_DS(on)	12 mΩ @ V_GS = 10 V, 25 °C - reduces conduction loss to ≤0.5 W at 25 A, easing thermal design.
R_DS(on) @ 5 V	14 mΩ @ V_GS = 5 V, 25 °C - ensures full enhancement using standard microcontroller GPIOs without level-shifting.
E_AS	140 mJ non-repetitive avalanche energy - sustains unclamped inductive kickback from 24 V solenoids or motors during fault conditions.

T_j max	175 °C - qualified for under-hood environments including transmission control modules and EPS ECUs.

Pinout & Package

Package: D2PAK (SOT404), plastic single-ended surface-mounted package with 3 leads (lead 2 cropped); mounting base electrically connected to drain terminal for low-inductance thermal and electrical path.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Logic-level input requiring ≤10 V for full enhancement; gate charge Q_G(tot) = 35 nC enables fast switching with <10 Ω driver.
2 (D)	Drain	Not externally accessible - internally bonded to mounting base; primary high-side connection point for load return path.
3 (S)	Source	Low-side reference node; connects to ground plane; internal source inductance 7.5 nH minimizes ringing in PWM-driven loads.
Mounting Base	Drain (electrical & thermal)	Provides primary heat transfer path to heatsink/chassis; must be soldered to ≥200 mm² copper area for rated power handling.

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level power FET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N6F7	60 V V_DS, 220 A I_D, 1.2 mΩ R_DS(on) @ 10 V - higher current, lower voltage, smaller DFN package.	Targeted at compact 12 V battery management systems; not rated for 75 V transients or AEC-Q101.	Select when board space is constrained and 60 V rating suffices; avoid for 42 V systems or automotive safety-critical use.
IRF1405ZPBF	55 V V_DS, 169 A I_D, 5.3 mΩ R_DS(on) @ 10 V - TO-220 package, no AEC qualification, higher gate charge (130 nC).	Suitable for industrial motor drives but lacks automotive qualification and thermal performance at elevated temperatures.	Choose for cost-sensitive non-automotive applications where 55 V rating and TO-220 mounting are acceptable.

Compared with STL220N6F7 and IRF1405ZPBF, the BUK9616-75B,118 uniquely combines 75 V rating, AEC-Q101 compliance, 14 mΩ R_DS(on) at 5 V, and 0.95 K/W thermal resistance-making it the only drop-in solution for thermally demanding, safety-critical 24 V/42 V automotive power switching.

FAQ

Is BUK9616-75B,118 pin-compatible with other D2PAK-packaged N-channel FETs?

No-pin 2 is internally connected to the mounting base and not externally accessible. Only pins 1 (gate) and 3 (source) are usable; the drain is exclusively routed through the mounting base. This differs from standard 3-pin D2PAK layouts and requires PCB layout adaptation to accommodate base-soldered drain connection.

What is the maximum safe operating area (SOA) limitation at 100 °C mounting base temperature?

At T_mb = 100 °C, the continuous drain current is derated to 47 A per limiting values table. The SOA curve (Figure 3) shows that at V_DS = 30 V, the device supports ≤100 A for 10 ms pulses but only ≤25 A for DC operation-dictated by thermal resistance and power dissipation limits, not just current rating.

Does BUK9616-75B,118 require a gate resistor for automotive PWM applications?

Yes-a 5–10 Ω series gate resistor is recommended to dampen ringing caused by 7.5 nH internal source inductance and PCB trace inductance. Without it, fast switching (t_f = 57 ns) can induce >10 V overshoot on gate drive lines, risking gate oxide stress in 12 V/24 V systems with long harness traces.

How does the source-drain diode performance compare to discrete Schottky solutions?

The integrated body diode has V_SD = 0.85 V at 25 A and 25 °C, higher than typical Schottky diodes (0.3–0.5 V), but offers matched thermal tracking and eliminates parasitic inductance from external components. Its 96 ns t_rr and 138 nC Q_r are optimized for snubberless inductive flyback in automotive solenoid drivers.
