Product details
Overview
BUK7L06-34ARC,127 from Nexperia (formerly Philips Semiconductors) is an N-channel TrenchMOS power MOSFET in TO-220 (SOT78C) package, rated for 34 V VDS, 5.1 mΩ RDS(on) at 10 V VGS, and 75 A continuous drain current at Tmb = 100 °C - designed for high-current 12 V automotive load switching including motors, lamps, and solenoids.
For engineers reviewing the BUK7L06-34ARC,127 datasheet, BUK7L06-34ARC,127 pinout, BUK7L06-34ARC,127 application, or BUK7L06-34ARC,127 equivalent, this part delivers Q101-compliant ruggedness, integrated gate resistor (11 Ω), 175 °C junction rating, and 1.0 J non-repetitive avalanche energy - critical for under-hood automotive power control where thermal stability and clamping reliability are mandatory.
Technical Context
This device implements a standard-level gate threshold architecture (VGS(th) = 2.2–3.8 V at 25 °C) with internal gate resistor (11 Ω) to dampen ringing and reduce EMI in high-di/dt switching. Its TrenchPLUS process enables low RDS(on) while maintaining robust avalanche capability (EDS(CL)S = 1.0 J).
Thermal design centers on mounting-base interface: Rth(j-mb) = 0.33–0.6 K/W enables efficient heatsink coupling, and the metal mounting base is electrically connected to drain - requiring isolation in PCB layout. The device supports pulsed peak currents up to 590 A (tp ≤ 10 µs) under defined conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 34 V DC - maximum drain-source blocking voltage; defines safe operation in 12 V automotive systems with load-dump transients. |
| RDS(on) | 5.1 mΩ typ @ VGS = 10 V, Tj = 25 °C - enables <1 W conduction loss at 45 A, critical for thermally constrained motor drivers. |
| ID cont | 75 A @ Tmb = 100 °C - package-limited continuous current; sets maximum steady-state load capacity with proper heatsinking. |
| Ptot | 250 W @ Tmb = 25 °C - total power dissipation limit; requires thermal derating above 25 °C mounting base temperature. |
| EDS(CL)S | 1.0 J non-repetitive - clamped inductive switching energy handling; ensures survival during relay coil or motor turn-off events. |
| VESD | 8 kV HBM - electrostatic discharge robustness per human body model; reduces risk of field failure during assembly and service. |
| Rth(j-mb) | 0.33 K/W typ - junction-to-mounting-base thermal resistance; determines minimum heatsink requirement for target Tj. |
| Qg(tot) | 82 nC - total gate charge; defines driver strength needed for fast switching (e.g., <200 ns td(off) with RG = 10 Ω). |
Pinout & Package
Package: TO-220 variant SOT78C - plastic single-ended package with isolated mounting base (electrically connected to drain), 3 leads, and one mounting hole for heatsink attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; accepts 0–20 V DC; internal 11 Ω resistor limits dV/dt-induced shoot-through and simplifies gate drive layout. |
| 2 (D) | Drain | Main power input; electrically tied to mounting base - requires insulated heatsink or thermal pad with dielectric barrier. |
| 3 (S) | Source | Power return path; referenced to system ground in low-side switch configuration; carries full load current. |
| Mounting base (mb) | Drain extension | Integral thermal and electrical connection to drain; primary heat transfer path to heatsink; must be isolated from chassis ground unless drain is grounded. |
Key Features
| Feature | Design Value |
|---|---|
| Q101 qualified | AEC-Q101 compliant for automotive use - validated for temperature cycling, humidity, and mechanical stress per automotive reliability standards. |
| 175 °C rated junction | Extended thermal operating range enables deployment in under-hood environments without derating at elevated ambient temperatures. |
| Integrated gate resistor | 11 Ω on-chip resistor suppresses gate oscillation and reduces external component count in high-frequency PWM applications. |
| Clamping diodes | On-die ESD and clamping structures protect gate and source-drain paths - eliminates need for external TVS in many 12 V load circuits. |
| TrenchPLUS technology | Optimized trench gate structure delivers lower RDS(on) × Qg figure-of-merit than planar MOSFETs - improves efficiency in high-duty-cycle switching. |

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 |
|---|---|---|---|
| STP75NF34 | Higher RDS(on) (7.5 mΩ), no integrated gate resistor, same TO-220 package. | Lacks built-in gate damping; requires external gate resistor for EMI control in high-speed switching. | Choose when cost sensitivity outweighs layout simplicity and EMI performance requirements. |
| IRF1404ZPBF | Lower voltage rating (40 V), higher RDS(on) (4.7 mΩ typ), no AEC-Q101 qualification. | Not automotive-qualified; unsuitable for production vehicles but acceptable for industrial prototypes. | Choose only for non-automotive 12 V systems where qualification is not mandated and thermal margin is sufficient. |
Compared with STP75NF34 and IRF1404ZPBF, the BUK7L06-34ARC,127 provides superior automotive readiness (Q101 + 175 °C), integrated gate resistance for cleaner switching, and higher avalanche ruggedness - making it the preferred choice for production-grade automotive power switching where reliability and regulatory compliance are non-negotiable.

FAQ
What is the maximum continuous drain current for BUK7L06-34ARC,127?
The BUK7L06-34ARC,127 supports 75 A continuous drain current at mounting base temperature (Tmb) = 100 °C, limited by package thermal constraints. At Tmb = 25 °C, the absolute maximum is 147 A but remains capped at 75 A due to package limitations - a key design boundary for heatsink sizing and system thermal management.
Does BUK7L06-34ARC,127 have an integrated gate resistor, and what is its value?
Yes, the BUK7L06-34ARC,127 includes an internal gate resistor of 11 Ω. This resistor damps gate oscillations during fast switching, reduces EMI, and simplifies gate driver design - eliminating the need for an external series gate resistor in most 12 V automotive applications.
Is BUK7L06-34ARC,127 qualified for automotive use?
Yes, the BUK7L06-34ARC,127 is AEC-Q101 qualified and rated for 175 °C junction temperature. It meets automotive reliability standards for temperature cycling, humidity, and mechanical stress - making it suitable for under-hood and body-control applications in production vehicles.
What is the avalanche energy rating of BUK7L06-34ARC,127?
The BUK7L06-34ARC,127 is rated for 1.0 J of non-repetitive drain-source clamped energy (EDS(CL)S) under specified test conditions (ID = 75 A, VDS ≤ 34 V, VGS = 10 V, starting at Tj = 25 °C). This ensures survivability during inductive load turn-off events like motor or solenoid de-energization.
How is the mounting base electrically connected in BUK7L06-34ARC,127?
In the BUK7L06-34ARC,127, the mounting base is electrically connected to the drain (pin 2). This requires dielectric isolation between the heatsink and system chassis/ground unless the drain node is intentionally grounded - a critical layout consideration for safety and noise immunity.
