Product details
Overview
BUK761R8-30C from Nexperia is an N-channel enhancement-mode TrenchMOS power FET in D2PAK (SOT404) package, rated for 30 V VDS, 1.5 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C, and 100 A continuous drain current at Tmb = 25 °C - designed for high-current automotive load switching including motors, lamps, and solenoids.
For engineers reviewing the BUK761R8-30C datasheet, BUK761R8-30C pinout, BUK761R8-30C application, or BUK761R8-30C equivalent, key selection criteria include its Q101 compliance, 175 °C junction rating, avalanche energy rating of 1.7 J, low-inductance internal layout (LD = 2.5 nH, LS = 7.5 nH), and standard-level gate drive compatibility with 10 V logic.
Technical Context
This device uses Nexperia's Ultra High-Performance (UHP) automotive TrenchMOS technology to achieve ultra-low on-resistance and robust avalanche ruggedness. Its gate threshold voltage ranges from 1 V at Tj = 175 °C to 4.4 V at Tj = −55 °C, ensuring reliable turn-on across automotive temperature extremes.
The integrated source-drain diode exhibits VSD = 0.85 V at IS = 25 A and Tj = 25 °C, with trr = 73 ns and Qr = 48 nC under defined conditions. Thermal resistance from junction to mounting base is 0.45 K/W, enabling high-power dissipation when mounted on a thermally optimized heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum blocking voltage for 12 V automotive systems with transient margin |
| RDS(on) | 1.5 mΩ (typ) at VGS = 10 V, ID = 25 A, Tj = 25 °C - Enables <1.5 W conduction loss at 100 A |
| ID (cont) | 100 A at Tmb = 25 °C - Limited by D2PAK package thermal capability |
| EDS(AL)S | 1.7 J - Non-repetitive avalanche energy supports inductive load turn-off without external snubbers |
| Tj max | 175 °C - Qualified per AEC-Q101 for under-hood automotive use |
| QG(tot) | 150 nC - Determines gate driver strength requirement for fast switching |
| Rth(j-mb) | 0.45 K/W - Low thermal resistance enables efficient heat transfer to PCB/heatsink |
Pinout & Package

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 |
|---|---|---|---|
| STL220N3LLH6 | 30 V, 2.2 mΩ RDS(on), 120 A ID, H2PAK-2 package, 175 °C rated | Higher RDS(on) but larger package footprint; lower gate charge (120 nC) | Preferred where gate drive efficiency is prioritized over conduction loss |
| IRF1404ZPBF | 40 V, 4.7 mΩ RDS(on), 202 A ID, TO-220AB package, 175 °C rated | Higher voltage rating and higher RDS(on); through-hole mounting only | Used when 40 V system margin or legacy through-hole assembly is required |
Compared with BUK761R8-30C, STL220N3LLH6 trades 0.7 mΩ higher on-resistance for reduced gate drive demand, while IRF1404ZPBF offers wider voltage headroom at the cost of significantly higher conduction loss and incompatible packaging - making BUK761R8-30C optimal for space-constrained, high-efficiency 12 V automotive switching.

FAQ
What is the maximum continuous drain current for BUK761R8-30C at 100 °C mounting base temperature?
The BUK761R8-30C supports 100 A continuous drain current at Tmb = 100 °C with VGS = 10 V, as specified in Table 4 of the datasheet. This rating is limited by package thermal capability rather than silicon limits, and derates linearly above 25 °C per Figure 1.
Is BUK761R8-30C suitable for high-frequency PWM switching applications?
Yes, BUK761R8-30C supports high-frequency PWM operation due to its low gate charge (QG(tot) = 150 nC) and fast switching times (td(on) = 52 ns, tf = 134 ns). Its low internal inductance (LS = 7.5 nH) further reduces ringing, making it suitable for PWM frequencies up to 20 kHz in motor and lighting control.
Does BUK761R8-30C have an integrated body diode, and what are its key parameters?
Yes, BUK761R8-30C includes an integrated source-drain diode with VSD = 0.85 V at IS = 25 A and Tj = 25 °C, reverse recovery time trr = 73 ns, and recovered charge Qr = 48 nC - enabling efficient freewheeling in inductive loads without external diodes.
What is the thermal resistance from junction to mounting base for BUK761R8-30C?
The thermal resistance from junction to mounting base (Rth(j-mb)) for BUK761R8-30C is 0.45 K/W, as specified in Table 5. This low value reflects the direct copper connection between the die and the exposed drain pad, enabling efficient heat transfer to the PCB or heatsink.
How does the gate-source threshold voltage of BUK761R8-30C vary with temperature?
The gate-source threshold voltage (VGS(th)) of BUK761R8-30C decreases with rising temperature: it is 1 V at Tj = 175 °C, 2–4 V at Tj = 25 °C, and up to 4.4 V at Tj = −55 °C. This negative temperature coefficient ensures stable turn-on behavior across the full automotive temperature range.
