Product details
Overview
BUK764R0-75C,118 from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS FET in D2PAK (SOT404) package, rated for 75 V VDS, 100 A continuous drain current at Tmb = 25 °C, and 175 °C junction temperature. It delivers 3.4 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C, and is engineered for high-reliability automotive power switching of 12 V motor, lamp, and solenoid loads under thermally demanding conditions.
For engineers reviewing the BUK764R0-75C,118 datasheet, BUK764R0-75C,118 pinout, BUK764R0-75C,118 application, or BUK764R0-75C,118 equivalent, this device is selected for its avalanche robustness (630 mJ unclamped), standard-level gate drive compatibility (VGS(th) = 2–4 V), and thermal performance (Rth(j-mb) = 0.45 K/W) in automotive PWM and load-switching designs.
Technical Context
This FET uses advanced TrenchMOS technology to achieve low on-resistance and high avalanche energy capability. Its gate threshold voltage (2–4 V at Tj = 25 °C) ensures reliable turn-on with standard 10 V gate drivers, while its 175 °C maximum junction temperature supports operation in engine bay environments without derating.
The device features a monolithic source-drain diode with 0.85–1.2 V forward voltage and 83 ns reverse recovery time, enabling efficient freewheeling in inductive switching. Its dynamic parameters-including 142 nC total gate charge and 67 nC gate-drain charge-support predictable PWM timing in high-frequency automotive control circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 75 V - Maximum drain-source blocking voltage; enables use in 12 V automotive systems with transient overvoltage margin. |
| RDS(on) | 3.4 mΩ (typ.) at VGS = 10 V, Tj = 25 °C - Low conduction loss supports <1 W dissipation at 50 A, reducing heatsink requirements. |
| ID (cont) | 100 A at Tmb = 25 °C - High current capability meets peak demand in starter relays and HVAC blower motors. |
| EAS | 630 mJ (unclamped) - Avalanche ruggedness allows safe operation during inductive load turn-off without external snubbers. |
| Rth(j-mb) | 0.45 K/W - Low junction-to-mounting-base thermal resistance enables direct PCB copper pad cooling in space-constrained modules. |
| QG(tot) | 142 nC - Gate charge value determines required driver current for <150 ns turn-on/turn-off times in 20 kHz PWM applications. |
| VGS(th) | 2–4 V at Tj = 25 °C - Standard-level threshold ensures compatibility with 5 V or 3.3 V microcontroller GPIOs via level-shifting or buffer stages. |
Pinout & Package
Package: D2PAK (SOT404), plastic single-ended surface-mounted package with 3 leads (one lead cropped); mounting base electrically connected to drain.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; accepts 10 V logic-level drive; requires ≥100 mA peak current to charge 142 nC gate capacitance within 1 µs. |
| 2 (D) | Drain | Main high-side power terminal; internally bonded to mounting base for low-inductance, high-current path and thermal conduction. |
| 3 (S) | Source | Power return and reference node; connects to ground plane; internal source inductance (7.5 nH) impacts switching ringing in fast PWM. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability across -55 °C to +175 °C operating range, including temperature cycling and humidity testing. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N4F7AG | 40 V VDS, 220 A ID, 0.75 mΩ RDS(on), PowerFLAT 5x6 package | Limited to 12 V systems with lower transient margin; higher current but lower voltage rating than BUK764R0-75C,118 | Select when higher current density and smaller footprint are prioritized over 75 V surge tolerance. |
| IRF1404ZLPbF | 40 V VDS, 180 A ID, 3.8 mΩ RDS(on), TO-220AB package | Non-automotive grade (no AEC-Q101), larger through-hole package, no avalanche rating specified | Use only in non-safety-critical industrial 12 V loads where qualification and thermal performance are secondary. |

FAQ
Is BUK764R0-75C,118 suitable for high-frequency PWM above 50 kHz?
No-its 142 nC total gate charge and 133 ns rise time make it optimized for 10–25 kHz automotive PWM (e.g., fan control, solenoid actuation). At >50 kHz, switching losses increase significantly due to gate drive power demand and internal inductance effects; lower-QG FETs like PMT270UN are better suited.
Can BUK764R0-75C,118 be used in a high-side configuration with 12 V supply?
Yes-it supports standard-level gate drive and is commonly deployed in high-side switching with a dedicated gate driver (e.g., NCV8402) that provides VGS ≥ 10 V referenced to the source. The mounting base (drain) must be isolated from heatsink if floating, or grounded if used as low-side.
What is the maximum allowable PCB copper area for thermal performance?
For optimal Rth(j-mb) = 0.45 K/W, the datasheet specifies a minimum 100 mm² copper pad (2-layer, 70 µm thick) directly under the mounting base. Increasing to 200 mm² reduces thermal resistance by ~15%, but further gains diminish without forced airflow or thermal vias to inner layers.
Does BUK764R0-75C,118 include integrated ESD protection?
No-the device has no built-in ESD protection circuitry. External TVS diodes (e.g., PESD5V0S1BA) are required on gate and drain terminals to meet ISO 10605 and IEC 61000-4-2 standards in automotive harness environments.
