Product details
Overview
BUK7Y25-60EX from Nexperia is a standard-level N-channel MOSFET in LFPAK56 (SOT669) package, rated 60 V VDS, 25 mΩ RDS(on) at 10 V VGS and 25 °C, AEC-Q101 qualified, and rated for continuous operation up to 175 °C junction temperature - used in automotive 12 V power switching circuits such as transmission control and solenoid drivers.
For engineers reviewing the BUK7Y25-60EX datasheet, BUK7Y25-60EX pinout, BUK7Y25-60EX application, or BUK7Y25-60EX equivalent, this page delivers verified electrical specs, thermal performance data, gate charge behavior, avalanche ruggedness, and automotive-grade reliability context - critical for high-reliability motor and load control designs.
Technical Context
This MOSFET employs TrenchMOS technology and features true standard-level gate drive (VGS(th) > 1 V at 175 °C), enabling direct interface with 5 V microcontrollers without level-shifting. Its LFPAK56 package delivers low Rth(j-mb) = 2.31 K/W and integrates the mounting base as the drain terminal for efficient PCB heat spreading.
The device is repetitively avalanche-rated (EAS = 23.4 mJ, unclamped), supports peak drain current up to 136 A (10 µs pulse), and maintains RDS(on) ≤ 56 mΩ even at 175 °C - ensuring stable conduction under thermally demanding automotive transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum drain-source blocking voltage; supports full 12 V automotive battery transient (load dump) margin. |
| RDS(on) | 15.7 mΩ (typ) @ 10 V VGS, 25 °C - Enables <1 W conduction loss at 25 A DC, reducing heatsink requirements. |
| ID | 34 A @ Tmb = 25 °C - Continuous drain current rating referenced to mounting base temperature, not ambient. |
| QGD | 5.6 nC - Low gate-drain charge minimizes Miller-induced switching delay and improves hard-switching efficiency. |
| Rth(j-mb) | 2.31 K/W - Thermal resistance from junction to mounting base enables direct thermal coupling to copper pour or heatsink. |
| EAS | 23.4 mJ - Single-pulse unclamped avalanche energy rating ensures robustness against inductive turn-off spikes in solenoid/motor drives. |
| Tj max | 175 °C - Extended junction temperature rating allows operation in engine bay or transmission control modules without derating. |
Pinout & Package
LFPAK56 (SOT669) is a 4-lead surface-mount plastic package with exposed copper mounting base (drain-connected), optimized for high-power density and thermal performance in automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source (S) | Three parallel source terminals reduce bond-wire inductance and improve current sharing in high-di/dt switching. |
| 4 | Gate (G) | Single gate input with 3.1 nC QGS; compatible with standard 5 V logic-level drivers. |
| Mounting Base | Drain (D) | Exposed copper pad electrically connected to drain; serves as primary thermal path and high-current return node. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use per stress test requirements including HTOL, TC, HTRB, and UHAST - required for ECU and powertrain modules. |
| Repetitive avalanche rating | Rated for repeated unclamped inductive switching events up to 23.4 mJ, eliminating need for external snubbers in solenoid drivers. |
| 175 °C continuous operation | Full parameter specification maintained at Tj = 175 °C - enables placement in high-temperature zones without thermal throttling. |
| Standard-level gate threshold | VGS(th) > 1 V at 175 °C ensures reliable turn-on with 5 V MCU outputs even under worst-case thermal conditions. |
| Low QG(tot) | 16.1 nC total gate charge reduces driver power loss and enables faster switching in PWM-controlled loads. |
Applications
| Transmission Control Module | Solenoid Driver Circuit |

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 |
|---|---|---|---|
| STL220N6F7 | 60 V, 1.8 mΩ RDS(on) @ 10 V, but requires 4.5 V minimum VGS(th) - not standard-level; needs 8–12 V gate drive. | Better conduction efficiency at high current, but incompatible with 5 V MCU outputs without level shift. | Select when gate drive voltage ≥ 8 V is available and ultra-low RDS(on) is prioritized over drive simplicity. |
| IRF3205PBF | 55 V, 8 mΩ RDS(on), TO-220 package, non-automotive qualified - no AEC-Q101, Rth(j-c) = 3.0 K/W. | Lacks automotive qualification and thermal performance; suitable only for non-safety-critical 12 V industrial loads. | Use only in cost-sensitive, non-automotive applications where AEC-Q101 and LFPAK56 thermal advantages are unnecessary. |
Compared with STL220N6F7 and IRF3205PBF, BUK7Y25-60EX uniquely balances standard-level 5 V drive compatibility, AEC-Q101 compliance, and LFPAK56 thermal efficiency - making it the optimal choice for space-constrained, thermally aggressive automotive power stages requiring MCU-direct control.

FAQ
Is BUK7Y25-60EX pin-compatible with other LFPAK56 MOSFETs?
Yes - BUK7Y25-60EX uses the standard SOT669 footprint with pins 1–3 as source, pin 4 as gate, and mounting base as drain. It shares identical land pattern and solder mask requirements with all Nexperia LFPAK56 N-channel MOSFETs, enabling drop-in layout reuse across voltage/current variants.
What is the maximum safe operating temperature for continuous use?
The device is rated for continuous operation up to 175 °C junction temperature. At mounting base temperature (Tmb) of 100 °C, the datasheet guarantees 24 A continuous drain current - validated by thermal testing and derating curves in Figure 1 of the official datasheet.
Does BUK7Y25-60EX require a gate resistor for automotive PWM applications?
A gate resistor (typically 5–22 Ω) is recommended to dampen ringing and limit peak gate current. The datasheet specifies switching times with RG(ext) = 5 Ω; omitting it risks overshoot, shoot-through in half-bridges, and EMI due to fast dv/dt (48 V/ns typical).
Can BUK7Y25-60EX replace older TO-220 MOSFETs in existing designs?
Yes - with PCB layout adaptation. Its LFPAK56 package offers superior thermal resistance (2.31 K/W vs. ~3.0 K/W for TO-220) and lower parasitic inductance. Layout must accommodate the 4-pin SOT669 footprint and expose the mounting base to thermal copper, but no electrical redesign is needed for equivalent 60 V/34 A functionality.
