Product details
Overview
BUK6Y12-30PX from Nexperia is an AEC-Q101 qualified N-channel automotive power MOSFET in LFPAK56 (SOT669) package, rated for 30 V VDSS, 120 A ID (TC = 25 °C), and 2.8 mΩ RDS(on) max at VGS = 10 V. It delivers high-current switching in engine control units, battery management systems, and 12 V ICE powertrain modules.
For engineers reviewing the BUK6Y12-30PX datasheet, BUK6Y12-30PX pinout, BUK6Y12-30PX application, or BUK6Y12-30PX equivalent, key selection criteria include its 120 A continuous drain rating at TC = 25 °C, 2.8 mΩ on-resistance, AEC-Q101 qualification, LFPAK56 thermal performance, and suitability for high-side load switching in automotive chassis and body electronics.
Technical Context
This MOSFET employs a trench-gate superjunction structure optimized for low conduction loss and fast switching with minimal gate charge (QG = 47 nC typ). Its 175 °C maximum junction temperature and robust avalanche rating (EAS = 520 mJ) support operation in thermally demanding under-hood environments.
The device features integrated ESD protection (HBM > 2 kV), operates with standard logic-level gate drive (VGS(th) = 1.0–2.5 V), and maintains stable RDS(on) across automotive temperature range (−40 °C to +175 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum drain-source blocking voltage for 12 V automotive rail switching |
| RDS(on) max | 2.8 mΩ @ VGS = 10 V - Enables <1 W conduction loss at 60 A, critical for thermal management in compact ECUs |
| ID continuous | 120 A @ TC = 25 °C - Supports high-current loads such as fuel pumps and cooling fans without external heatsinking |
| QG | 47 nC typ - Reduces gate drive power and enables efficient PWM control up to 100 kHz |
| EAS | 520 mJ - Withstands repetitive inductive switching stress in motor and solenoid drive applications |
| TJ max | 175 °C - Qualified for under-hood use including engine bay and transmission control modules |
| AEC-Q101 | Qualified - Meets automotive reliability requirements for zero-defect field performance over 15+ year vehicle lifetime |
Pinout & Package
BUK6Y12-30PX uses the LFPAK56 (SOT669) package: 5.0 × 6.0 × 1.0 mm, copper-clip bonded construction with exposed drain pad for superior thermal resistance (RθJC = 0.9 K/W) and mechanical ruggedness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | Main current path output | Exposed copper pad - soldered directly to PCB thermal plane for optimal heat dissipation |
| Source (S) | Current return path | Three internal source leads - low-inductance connection for stable switching and reduced ringing |
| Gate (G) | Control input | ESD-protected MOS gate - compatible with 3.3 V/5 V microcontroller outputs without level shifting |
Key Features
| Feature | Design Value |
|---|---|
| LFPAK56 clip-bond packaging | Reduces RθJC by 50 % vs. DPAK, enabling 120 A operation with minimal board area |
| 175 °C rated junction | Supports placement in high-temperature zones (e.g., near engine block or exhaust manifold) |
| Low QG/QGD ratio | Improves switching efficiency and reduces Miller-induced shoot-through risk in half-bridge configurations |
| Avalanche-rated (UIS) | Eliminates need for external snubbers in inductive load circuits like fuel injectors and ABS solenoids |
| Leadless, side-wettable flanks | Enables automated optical inspection (AOI) and ensures reliable solder joint formation in high-volume SMT lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPB017N10N5 | 100 V VDSS, 175 A ID, 1.7 mΩ RDS(on), TO-263 package | Higher voltage margin for future 48 V hybrid architectures; larger footprint and higher thermal mass | Select when designing for dual-voltage platforms or requiring >30 V transient tolerance |
| STL220N3LLH6 | 30 V VDSS, 120 A ID, 2.4 mΩ RDS(on), PowerFLAT 5x6 | Similar RDS(on) but lower EAS (380 mJ); no AEC-Q101 documentation publicly available | Prefer BUK6Y12-30PX where full AEC-Q101 traceability and 520 mJ UIS are required for safety-critical functions |
Compared with IPB017N10N5 and STL220N3LLH6, BUK6Y12-30PX offers the optimal balance of 30 V rating, 2.8 mΩ on-resistance, AEC-Q101 certification, and LFPAK56 thermal performance-making it the preferred choice for cost-sensitive, space-constrained 12 V automotive power switching where reliability and manufacturability are paramount.

FAQ
What is the maximum pulsed drain current (IDM) for BUK6Y12-30PX?
The BUK6Y12-30PX supports IDM = 480 A (tp ≤ 10 µs, duty cycle ≤ 1 %) per the official Nexperia datasheet. This rating enables safe handling of short-duration inrush currents in motor and solenoid applications without thermal runaway, provided PCB layout provides adequate copper area for transient heat dissipation.
Does BUK6Y12-30PX require a gate resistor for stability in automotive PWM applications?
Yes-a 10–22 Ω series gate resistor is recommended to dampen parasitic oscillation and limit peak gate current during fast switching. The device's low input capacitance (Ciss = 4900 pF) and gate threshold (1.0–2.5 V) make it sensitive to layout-induced ringing, especially in high-noise engine bay environments.
Can BUK6Y12-30PX be used in parallel configurations for higher current capacity?
Parallel operation is feasible due to its positive temperature coefficient of RDS(on), which promotes current sharing. However, strict matching of gate drive loop inductance and PCB copper balance is required. Nexperia recommends using individual gate resistors and Kelvin source connections to avoid thermal runaway in multi-device arrays.
Is the LFPAK56 package RoHS and REACH compliant?
Yes-the BUK6Y12-30PX LFPAK56 package meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin plating on terminals and halogen-free molding compound. Full compliance documentation is available through Nexperia's material declaration portal.
