Product details

Overview

BUK724R5-30C from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS FET in DPAK (SOT428) package, designed for automotive 12V power switching. It delivers 75 A continuous drain current at T_mb = 100 °C, 30 V V_DS, and 3.8 mΩ R_DS(on) @ 10 V_GS/25 A/25 °C, with avalanche energy rating of 329 mJ - enabling robust motor, lamp, and solenoid load control in engine bay environments up to 175 °C junction temperature.

For engineers reviewing the BUK724R5-30C datasheet, BUK724R5-30C pinout, BUK724R5-30C application, or BUK724R5-30C equivalent, this device is selected for high-reliability 12V automotive PWM power stages where standard-level gate drive (10 V), thermal resilience, and unclamped avalanche ruggedness are critical design requirements.

Technical Context

This MOSFET employs Nexperia's TrenchMOS technology to achieve low on-resistance and fast switching with controlled Q_G (62 nC) and Q_GD (21 nC). Its gate threshold voltage (2–4 V @ 25 °C) ensures reliable turn-on with standard 10 V logic drivers while maintaining safe margin against spurious conduction at elevated temperatures.

The device integrates a monolithic source-drain diode with 0.85 V forward drop @ 20 A and 40 ns reverse recovery time, supporting freewheeling in inductive loads. Thermal resistance from junction to mounting base is 0.65 K/W typical, enabling high-power dissipation when soldered to a thermally optimized PCB copper plane.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V maximum drain-source voltage - supports full 12V automotive battery transient range including load dump spikes up to 30 V.
R_DS(on)	3.8 mΩ typical @ V_GS = 10 V, I_D = 25 A, T_j = 25 °C - enables <1 W conduction loss at 50 A, reducing heatsink requirements.
I_D (cont)	75 A @ T_mb = 100 °C - defines usable continuous current under real-world board-mount thermal conditions.
E_AS	329 mJ non-repetitive avalanche energy - allows safe operation during inductive turn-off transients without external snubbers.
R_th(j-mb)	0.65 K/W typical junction-to-mounting-base thermal resistance - confirms direct thermal path to PCB copper, critical for automotive under-hood reliability.
Q_GD	21 nC gate-drain charge - determines Miller plateau duration and influences switching loss and dV/dt immunity in hard-switched PWM.
V_GS(th)	2–4 V @ T_j = 25 °C - ensures clean turn-on with 5 V or 10 V gate drivers while retaining noise margin at high temperature.

Pinout & Package

Package: SOT428 (DPAK), plastic single-ended surface-mounted package with 3 leads (lead 2 cropped); mounting base (mb) is electrically connected to drain and serves as primary thermal interface.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control terminal; requires 10 V drive for full enhancement; threshold 2–4 V enables compatibility with standard microcontroller GPIOs.
2 (D)	Drain	Main high-side power terminal; internally bonded to mounting base - must be connected to PCB copper pour for thermal management.
3 (S)	Source	Power return path and reference for gate drive; low-inductance layout essential to minimize switching oscillation.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive-grade reliability across -55 °C to +175 °C, including temperature cycling, humidity, and mechanical shock testing.
Avalanche rugged	Rated for 329 mJ unclamped inductive energy - eliminates need for external clamping diodes in solenoid/motor driver designs.
Standard-level gate drive	Optimized for 10 V gate drive; avoids requirement for charge pump or level-shifter circuits in 12 V systems.
175 °C max junction temperature	Enables operation in high-ambient locations (e.g., near engine block) without derating beyond datasheet curves.
Low internal inductance	L_D = 2.5 nH, L_S = 7.5 nH - reduces voltage overshoot and ringing during fast switching transitions.

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
STL220N3LLH6	30 V, 220 A rated, 1.8 mΩ R_DS(on), PowerFLAT 5x6 package, higher current but larger footprint and no AEC-Q101 certification in base variant.	Targeted at higher-current industrial motor drives; lacks automotive qualification unless specified as STL220N3LLH6AK.	Select only if >100 A continuous current is required and AEC-Q101 is not mandated for the subsystem.
IRF1404ZLPbF	40 V, 195 A, 3.8 mΩ R_DS(on), TO-220AB package, non-automotive grade, 175 °C rating but no avalanche energy spec.	Used in cost-sensitive 12V/24V industrial power supplies; lacks automotive qualification and defined E_AS.	Acceptable for non-automotive 12V systems where qualification and avalanche safety are secondary to cost and availability.

Compared with STL220N3LLH6 and IRF1404ZLPbF, the BUK724R5-30C uniquely combines AEC-Q101 qualification, verified 329 mJ avalanche capability, and DPAK thermal performance - making it the only choice for production automotive power switches requiring both functional safety and thermal resilience in constrained layouts.

FAQ

Is BUK724R5-30C suitable for high-frequency PWM above 100 kHz?

Yes - with Q_G(tot) = 62 nC and Q_GD = 21 nC, the device supports efficient switching up to 500 kHz in well-designed gate-drive circuits. Layout must minimize source inductance (L_S = 7.5 nH) to prevent oscillation; recommended gate resistor is 5–10 Ω for 10 V drive.

What is the maximum allowable mounting base temperature for continuous 75 A operation?

The datasheet specifies 75 A continuous drain current at T_mb = 100 °C. Operation above this requires derating per Figure 1; at T_mb = 125 °C, continuous current drops to ~55 A. Junction temperature must remain ≤175 °C, enforced by R_th(j-mb) = 0.65 K/W typical.

Does the source-drain diode support bidirectional current in battery disconnect applications?

Yes - the integrated body diode has 0.85 V forward voltage at 20 A and 40 ns reverse recovery time, enabling use in reverse-polarity protection and regenerative braking paths. However, its 75 A continuous rating applies only in forward conduction; reverse blocking is limited to V_DS = 30 V.

Can BUK724R5-30C replace older BUZ70-series MOSFETs in legacy automotive designs?

Yes - it shares identical DPAK (SOT428) footprint and pinout, offers lower R_DS(on) (3.8 mΩ vs. ~5.5 mΩ), improved avalanche rating (329 mJ vs. 220 mJ), and full AEC-Q101 qualification. Gate threshold remains compatible (2–4 V), allowing drop-in replacement with enhanced thermal and ruggedness margins.
