Product details

Overview

BUK7613-75B,118 from Nexperia is a standard-level N-channel TrenchMOS FET in D2PAK (SOT404) package, rated for 75 V drain-source voltage, 75 A continuous drain current at 25 °C mounting base temperature, and 157 W total power dissipation. It delivers 11.7 mΩ typical R_DS(on) at V_GS = 10 V and T_j = 25 °C, with AEC-Q101 qualification for automotive critical loads including 12 V/24 V motor and solenoid control.

For engineers reviewing the BUK7613-75B,118 datasheet, BUK7613-75B,118 pinout, BUK7613-75B,118 application, or BUK7613-75B,118 equivalent, key selection criteria include its 175 °C junction rating, low gate charge (Q_G(tot) = 40 nC), avalanche energy rating (125 mJ), and thermal resistance from junction to mounting base (0.95 K/W).

Technical Context

This device operates as a single N-channel enhancement-mode power switch with gate threshold voltage of 2–4 V at 25 °C and reduced to 1 V at 175 °C, enabling compatibility with standard 10 V gate drivers. Its trench-based MOSFET architecture supports fast switching (t_d(on) = 18 ns, t_f = 26 ns) while maintaining robust unclamped inductive switching capability.

The integrated source-drain diode exhibits 0.85–1.2 V forward voltage at 15 A and 25 °C, with reverse recovery time of 74 ns and recovered charge of 94 nC under defined test conditions. Thermal design is enabled by direct-mounting base (connected to drain) and low R_th(j-mb) of 0.95 K/W.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	75 V maximum - supports 42 V automotive systems with margin against load dump transients
I_D (continuous)	75 A at T_mb = 25 °C - enables high-current DC loads without external heatsink in moderate ambient
R_DS(on)	11.7 mΩ typ @ V_GS = 10 V, I_D = 25 A, T_j = 25 °C - minimizes conduction loss in 12 V/24 V power distribution
Q_G(tot)	40 nC - reduces gate drive power requirement and enables efficient PWM operation up to ~100 kHz
E_AS	125 mJ non-repetitive avalanche energy - sustains inductive turn-off stress in solenoid/motor circuits without snubber
T_j max	175 °C - allows operation in engine bay or under-hood environments without derating at elevated ambient
R_th(j-mb)	0.95 K/W - enables direct thermal coupling to PCB copper or heatsink via exposed drain pad

Pinout & Package

Package: SOT404 (D2PAK), plastic surface-mount package with exposed drain mounting base (mb), 3 leads (lead 2 cropped), footprint per Figure 16.

Pin/Terminal	Circuit Role	Design Meaning

2 (D)	Drain	Not externally accessible - internally connected to mounting base; primary high-side switching node
3 (S)	Source	Power return path and reference for gate drive; connects to system ground or low-side switch node
mb	Mounting Base	Electrically tied to drain; provides primary thermal path and mechanical anchoring to PCB/heatsink

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 uninterrupted operation in under-hood environments where ambient exceeds 125 °C
Low R_DS(on) × Q_G figure-of-merit	11.7 mΩ × 40 nC = 468 mΩ·nC - balances conduction and switching losses for high-efficiency 12–42 V DC switching
Unclamped avalanche ruggedness	125 mJ E_AS - eliminates need for external clamping diodes in inductive load driving
Standard-level gate drive	V_GS(th) 2–4 V range ensures reliable turn-on with 5 V or 10 V controllers without level-shifting circuitry

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
STL125N4LF6AG	40 V V_DS, 125 A I_D, 2.5 mΩ R_DS(on), PowerFLAT 5x6 package	Limited to 24 V systems; lower R_DS(on) but no avalanche rating specified	Select when higher current and lower conduction loss are prioritized over 42 V compatibility and unclamped inductive robustness
IRFB4115PBF	150 V V_DS, 115 A I_D, 11.5 mΩ R_DS(on), TO-220AB package	Higher voltage rating but larger through-hole package; not AEC-Q101 qualified	Select for industrial 48 V DC systems where automotive qualification is not required and manual assembly is acceptable

Compared with STL125N4LF6AG and IRFB4115PBF, BUK7613-75B,118 uniquely combines 75 V rating, AEC-Q101 compliance, 175 °C operation, and verified 125 mJ avalanche energy-making it the only drop-in solution for thermally constrained, safety-critical 12–42 V automotive switching where reliability under transient stress is mandatory.

FAQ

Is BUK7613-75B,118 suitable for high-frequency PWM motor control?

Yes - with 18 ns turn-on delay, 26 ns fall time, and 40 nC total gate charge, it supports efficient PWM operation up to approximately 100 kHz in 12–42 V motor drives. Its low R_DS(on) × Q_G figure-of-merit minimizes combined conduction and switching losses, and the 0.95 K/W junction-to-mounting-base thermal resistance enables stable thermal performance under sustained duty cycles.

Does BUK7613-75B,118 require a gate resistor for automotive solenoid driving?

A gate resistor is recommended: 10 Ω is specified in the datasheet for switching characterization (V_GS = 10 V, R_G(ext) = 10 Ω). This value balances EMI suppression and switching speed - reducing dV/dt-induced noise while maintaining <1 µs turn-off delay needed for precise solenoid timing in fuel injectors and transmission actuators.

Can BUK7613-75B,118 replace older BUZ70 or STP75NF75 in existing designs?

No direct replacement - BUK7613-75B,118 uses D2PAK (SOT404) packaging versus TO-220 for BUZ70 and STP75NF75, requiring PCB layout revision. Electrically, its 75 V rating matches STP75NF75 but differs from BUZ70's 100 V rating; R_DS(on) is lower (11.7 mΩ vs. ~14 mΩ), improving efficiency but demanding updated thermal validation due to higher power density.

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 54 A per Table 4. The SOA curve (Figure 3) shows that at V_DS = 30 V, the device supports ≤45 A DC; at V_DS = 60 V, it supports ≤12 A DC. Pulse operation (tp ≤10 µs) extends peak current to 304 A regardless of temperature, limited only by bond wire integrity and avalanche energy absorption.
