Product details

Overview

BUK625R2-30C from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS FET in DPAK (SOT428) package, designed for automotive power switching with 30 V V_DS, 4.4 mΩ R_DS(on) @ 10 V_GS/25 °C, 90 A continuous drain current, and 175 °C junction rating-used in electric power steering and start-stop micro-hybrid systems.

For engineers reviewing the BUK625R2-30C datasheet, BUK625R2-30C pinout, BUK625R2-30C application, or BUK625R2-30C equivalent, key selection criteria include gate drive compatibility (standard/logic-level), thermal robustness in constrained mounting-base environments, avalanche energy handling (153 mJ), and automotive-grade reliability validation per AEC-Q101.

Technical Context

This intermediate-level gate-drive MOSFET employs TrenchMOS technology to achieve low on-resistance while maintaining stable threshold voltage (1.8–2.8 V) across -55 to 175 °C. Its optimized charge profile delivers Q_G(tot) = 54.8 nC and Q_GD = 16.2 nC at 10 V_GS, enabling fast switching with controlled dV/dt in high-current automotive loads.

The device integrates a monolithic source-drain diode with V_SD = 0.8–1.2 V @ 25 A and t_rr = 45 ns, supporting synchronous rectification and freewheeling in motor control. Thermal resistance R_th(j-mb) = 1.17 K/W ensures efficient heat transfer to the PCB-mounted base, critical for sustained 81 A operation at 100 °C mounting temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V maximum - defines safe blocking capability in 12 V automotive battery systems with load-dump transients.
R_DS(on)	4.4 mΩ typical @ V_GS = 10 V, I_D = 15 A, T_j = 25 °C - enables <1 W conduction loss at 50 A, reducing heatsink requirements.
I_D (continuous)	90 A @ T_mb = 25 °C - limited by package thermal capacity; derates to 81 A at T_mb = 100 °C per Figure 1.
E_AS	153 mJ non-repetitive avalanche energy - supports unclamped inductive turn-off in solenoid and motor control without external snubbers.
T_j max	175 °C - allows operation in under-hood environments where ambient exceeds 125 °C with proper thermal design.
Q_G(tot)	54.8 nC @ V_DS = 24 V, I_D = 25 A - determines gate driver current demand and switching loss trade-off in PWM applications.
C_iss	2600–3470 pF @ V_DS = 25 V - influences high-frequency gate drive stability and EMI filtering requirements.

Pinout & Package

Package: SOT428 (DPAK), plastic single-ended surface-mounted package with 3 leads (one lead cropped); mounting base (mb) electrically connected to drain for low-inductance thermal and power path.

Pin/Terminal	Circuit Role	Design Meaning
1	G (Gate)	Control terminal; accepts standard (10 V) or logic-level (4.5–5 V) drive; threshold V_GS(th) = 1.8–2.8 V ensures reliable turn-on with MCU GPIO.
2	D (Drain)	Main power output; internally bonded to mounting base (mb) - requires direct thermal pad connection to PCB copper for R_th(j-mb) = 1.17 K/W performance.
3	S (Source)	Power return and reference node; internal source inductance L_S = 7.5 nH impacts high-speed switching ringing and layout sensitivity.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive use including temperature cycling, HTRB, and UHAST - eliminates need for additional qualification testing in Tier-1 designs.
175 °C junction rating	Enables operation in high-ambient under-hood locations (e.g., near engine block or transmission) without derating beyond datasheet curves.
Logic-level gate compatibility	R_DS(on) = 7.1 mΩ @ V_GS = 4.5 V ensures full enhancement with 3.3 V/5 V MCUs - avoids level-shifter complexity in compact ECUs.
Mounting-base thermal path	Low R_th(j-mb) = 1.17 K/W allows >80% of total power dissipation to be routed through PCB copper, reducing reliance on external heatsinks.
Integrated source-drain diode	V_SD = 0.8–1.2 V and t_rr = 45 ns support efficient freewheeling in brushed DC motor drives without discrete diode addition.

Applications

Electric Power Steering (EPS)

Start-Stop Micro-Hybrid Systems

Use Scenario: High-current H-bridge phase leg switching for brushless EPS motor commutation under transient torque demands up to 150 A peak.

IC Role / Device Role / Timing Role: Low-side and high-side power switch; handles bidirectional current with integrated body diode recovery during PWM dead-time.

Use Value: 4.4 mΩ R_DS(on) minimizes conduction loss at 90 A continuous, while 153 mJ avalanche rating absorbs inductive kickback during fault shutdown.

Use Scenario: 12 V battery main contactor replacement in start-stop systems, cycling thousands of times over vehicle lifetime.

IC Role / Device Role / Timing Role: Solid-state relay replacement; switches battery to starter motor and auxiliary loads with precise timing control and zero arcing.

Use Value: AEC-Q101 qualification and 175 °C rating ensure reliability across extreme thermal cycles; 81 A @ 100 °C T_mb supports sustained cranking loads.

Transmission Control Solenoids

LED Headlamp Dimming Drivers

Use Scenario: Proportional current control of electro-hydraulic solenoids regulating line pressure and shift timing in automatic transmissions.

IC Role / Device Role / Timing Role: PWM-controlled high-side or low-side switch; operates at 100–500 Hz with tight duty-cycle resolution.

Use Value: Low Q_GD = 16.2 nC and fast t_f = 66 ns enable clean PWM edges, minimizing solenoid coil heating and improving position accuracy.

Use Scenario: High-efficiency dimming driver for adaptive LED headlamps requiring >100 W per channel with thermal margin in sealed housings.

IC Role / Device Role / Timing Role: Synchronous buck switch; handles 5–10 A continuous LED current with high-frequency (200–500 kHz) switching.

Use Value: C_iss = 2600–3470 pF and Q_G(tot) = 54.8 nC allow stable gate drive with standard 1 A drivers; R_DS(on) < 5 mΩ reduces thermal load in confined optics modules.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N3LLH6	30 V, 220 A, R_DS(on) = 1.7 mΩ @ 10 V - larger die, higher current, TO-263 package; Q_G(tot) = 105 nC.	Requires higher gate drive strength; better suited for high-power inverters than space-constrained EPS modules.	Select when >120 A continuous current or lower R_DS(on) is required; verify PCB thermal relief for TO-263 footprint.
IRF3205PBF	55 V, 110 A, R_DS(on) = 8.0 mΩ @ 10 V - non-automotive grade, 175 °C rated but not AEC-Q101 qualified.	Lacks automotive reliability validation; unsuitable for safety-critical EPS or transmission control per ISO 26262.	Acceptable only for non-safety 12 V industrial motor controls; avoid in OEM automotive production.

Compared with STL220N3LLH6 and IRF3205PBF, BUK625R2-30C offers optimal balance of AEC-Q101 compliance, DPAK-mounting flexibility, and 4.4 mΩ conduction loss - making it preferred for thermally constrained, high-reliability automotive modules where gate drive simplicity and qualification traceability are mandatory.

FAQ

Is BUK625R2-30C suitable for logic-level gate drive from a 3.3 V microcontroller?

Yes - BUK625R2-30C achieves R_DS(on) = 7.1 mΩ @ V_GS = 4.5 V and 15 A, confirming full enhancement with 3.3 V logic-level sources when used with appropriate gate resistor and layout. V_GS(th) ranges from 1.8–2.8 V, ensuring reliable turn-on even at elevated temperatures.

What is the maximum continuous drain current at 100 °C mounting base temperature?

The datasheet specifies I_D = 81 A continuous at T_mb = 100 °C and V_GS = 10 V (Figure 1). This derating reflects thermal limits of the DPAK package; operation above this requires active cooling or reduced duty cycle per SOA curves in Figure 3.

Does BUK625R2-30C include an integrated body diode, and what are its key parameters?

Yes - it features a monolithic source-drain diode with forward voltage V_SD = 0.8–1.2 V @ 25 A and reverse recovery time t_rr = 45 ns (T_j = 25 °C). Q_r = 61 nC supports efficient freewheeling in motor and solenoid applications without external diodes.

How does the mounting base connection affect PCB layout and thermal design?

The mounting base (mb) is electrically tied to the drain and serves as the primary thermal path. It must be soldered to a large, low-thermal-resistance copper pour (≥200 mm² recommended) with ≥4 thermal vias to inner ground planes to achieve the specified R_th(j-mb) = 1.17 K/W and prevent junction overheating.
