Product details

Overview

BUK624R5-30C from Nexperia is a 30 V, 110 A, logic-level N-channel TrenchMOS power MOSFET in SOT1205 (LFPAK56) package with R_DS(on) of 4.5 mΩ at V_GS = 10 V and 6.2 mΩ at V_GS = 4.5 V, designed for high-efficiency DC-DC conversion and motor control in automotive body electronics.

For engineers reviewing the BUK624R5-30C datasheet, BUK624R5-30C pinout, BUK624R5-30C application, or BUK624R5-30C equivalent, key selection criteria include low R_DS(on) at 4.5 V drive, AEC-Q101 qualification, SOA robustness under repetitive avalanche, and LFPAK56 thermal performance in space-constrained PCB layouts.

Technical Context

This MOSFET uses Nexperia's TrenchMOS technology to achieve low on-resistance and fast switching with minimal gate charge (Q_G = 52 nC typ, Q_GD = 14 nC typ). It supports 100% rated current at T_c = 25 °C and features guaranteed avalanche energy rating (E_AS = 470 mJ).

The device integrates an integrated ESD protection diode (HBM Class 3B), operates over -55 °C to +175 °C junction temperature range, and meets automotive-grade reliability standards including AEC-Q101 stress testing and zero defect manufacturing controls.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30 V - maximum drain-source voltage for 12 V automotive rail systems with load dump margin
R_DS(on) @ V_GS = 10 V	4.5 mΩ - enables <1 W conduction loss at 10 A continuous drain current
R_DS(on) @ V_GS = 4.5 V	6.2 mΩ - ensures full enhancement with standard 3.3 V/5 V logic-level microcontroller GPIOs
I_D (continuous)	110 A - supports high-current solenoid and pump drivers without external heatsinking at T_c = 25 °C
Q_G	52 nC - reduces gate drive power and enables efficient 100 kHz+ PWM switching in buck converters
E_AS	470 mJ - sustains repetitive inductive turn-off events in motor commutation without derating

Pinout & Package

SOT1205 (LFPAK56) package: copper-clip leadframe with exposed drain pad for low thermal resistance (R_th(j-c) = 0.9 K/W) and high power density mounting.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current path from source to load	Connected to exposed copper pad - must be soldered to large PCB copper area for thermal management
Source (S)	Reference node for gate drive and current return	Two parallel pins provide low-inductance return path for high di/dt switching
Gate (G)	Control terminal for channel conduction	Logic-level compatible; requires <1 µF local decoupling near driver IC to suppress ringing

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive applications including engine bay and chassis modules
LFPAK56 package	Thermal resistance 3× lower than DPAK; enables 25% higher current density in same footprint
Repetitive avalanche rated	Guaranteed E_AS = 470 mJ allows safe operation in inductive load switching without snubbers
Low Q_GD/Q_G ratio	0.27 - improves hard-switching efficiency and reduces Miller-induced shoot-through risk

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPB017N10N5	100 V V_DSS, 17.5 mΩ R_DS(on) @ 10 V, larger TO-263 package	Higher voltage margin but 3.9× higher R_DS(on); suited for 24 V industrial systems	Select when system voltage exceeds 16 V or board layout allows larger thermal pad
STL220N3LLH6	30 V V_DSS, 2.2 mΩ R_DS(on) @ 10 V, PowerFLAT 5x6 package, no AEC-Q101	Lower on-resistance but unqualified for automotive; limited to commercial temperature range	Choose only for cost-sensitive non-automotive applications where -40 °C operation is not required

Compared with IPB017N10N5 and STL220N3LLH6, BUK624R5-30C uniquely balances automotive qualification, logic-level drive, and LFPAK56 thermal performance for 12 V body electronics-offering best-in-class R_DS(on) per mm² among AEC-Q101 30 V MOSFETs.

FAQ

What is the maximum pulsed drain current (I_DM) rating for BUK624R5-30C?

The BUK624R5-30C has a specified I_DM of 440 A at T_c = 25 °C with pulse width ≤ 10 µs and duty cycle ≤ 1%. This rating reflects its ability to handle short-duration inrush or fault currents in solenoid and motor startup scenarios without thermal runaway.

Does BUK624R5-30C require a gate resistor for automotive PWM applications?

Yes-a 10 Ω to 22 Ω gate series resistor is recommended to dampen ringing and limit peak gate current during 100–500 kHz PWM switching. This prevents overshoot beyond ±20 V absolute maximum gate voltage and ensures reliable operation with standard automotive gate drivers.

Can BUK624R5-30C be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(on) enables stable current sharing. Parallel operation requires matched gate drive routing, symmetrical PCB copper pour, and individual gate resistors. Derating to 90% of total rated current per device is advised for thermal margin.

Is the drain-source diode body diode optimized for reverse recovery in freewheeling applications?

No-the intrinsic body diode has t_rr ≈ 55 ns and Q_rr ≈ 120 nC, making it unsuitable for high-frequency freewheeling. External Schottky or SiC diodes are recommended for synchronous rectification or fast-recovery requirements above 100 kHz.
