Product details
Overview
BUK7619-100B,118 from Nexperia is an N-channel enhancement-mode TrenchMOS power FET in D2PAK (SOT404) package, rated for 100 V VDS, 64 A continuous drain current at 25 °C, and 17 mΩ typical RDS(on) at VGS = 10 V. It serves as a high-current, automotive-grade switching device for 12 V/24 V load control in motor, lamp, and solenoid applications.
For engineers reviewing the BUK7619-100B,118 datasheet, BUK7619-100B,118 pinout, BUK7619-100B,118 application, or BUK7619-100B,118 equivalent, key selection considerations include its Q101 automotive qualification, 175 °C junction rating, unclamped avalanche energy of 222 mJ, thermal resistance Rth(j-mb) = 0.74 K/W, and standard-level gate drive compatibility.
Technical Context
This device employs Nexperia's High Performance Automotive (HPA) TrenchMOS technology, delivering low on-resistance with robust avalanche ruggedness. Its gate threshold voltage ranges from 2 V to 4 V at 25 °C and remains functional down to 1 V at 175 °C, enabling stable operation across wide temperature extremes.
The source-drain diode exhibits VSD = 0.85 V at 25 A and 25 °C, with reverse recovery time trr = 116 ns and recovered charge Qr = 130 nC - characteristics critical for inductive switching reliability in automotive power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - Maximum drain-source blocking voltage; supports 12 V/24 V/42 V automotive systems with margin against transients. |
| RDS(on) | 17 mΩ (typ) at VGS = 10 V, Tj = 25 °C - Enables low conduction loss in high-current switching paths (e.g., 64 A @ 25 °C). |
| ID | 64 A continuous at Tmb = 25 °C - Sustains high-load currents without external heatsink under moderate mounting base conditions. |
| EDS(AL)S | 222 mJ (unclamped) - Withstands single-pulse inductive energy spikes common in motor/solenoid turn-off events. |
| Rth(j-mb) | 0.74 K/W - Enables efficient heat transfer to PCB copper or heatsink; supports >150 W dissipation with modest thermal interface. |
| QG(tot) | 53 nC - Determines gate driver strength requirement; compatible with standard automotive gate drivers (e.g., UCC27531, TC4427). |
| VGS(th) | 2–4 V at 25 °C - Ensures reliable turn-on with standard 5 V or 12 V logic-level signals; retains functionality at elevated temperatures. |
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; requires ≥10 V for full enhancement; gate leakage <100 nA ensures low standby power. |
| 2 (D) | Drain | Main high-side power terminal; electrically tied to mounting base for thermal and electrical connection to heatsink/PCB plane. |
| 3 (S) | Source | Power return path; referenced to system ground in low-side switch configurations; forms cathode of integrated body diode. |
| Mounting base (mb) | Drain extension | Thermally and electrically connected to drain (Pin 2); must be soldered to large copper area or heatsink for thermal management. |
Key Features
| Feature | Design Value |
|---|---|

| 175 °C maximum junction temperature | Supports operation in under-hood environments without derating at ambient up to 125 °C when properly heatsinked. |
| Standard-level gate drive | Turns fully on with 10 V gate-source voltage - eliminates need for level-shifting circuitry in 12 V battery-referenced systems. |
| Low RDS(on) × QG figure-of-merit | ~900 mΩ·nC - balances conduction and switching losses for high-efficiency PWM control in motor drives. |
| Integrated body diode with soft recovery | trr = 116 ns, Qr = 130 nC - Reduces voltage overshoot and EMI during freewheeling in inductive loads. |

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 |
|---|---|---|---|
| STP110N10F7 | 100 V, 110 A, RDS(on) = 8.5 mΩ (typ), TO-220FP package, no AEC-Q101 certification | Higher current capability but larger footprint and non-automotive qualified; requires external heatsink | Preferred for cost-sensitive industrial mains-powered equipment where automotive qualification is unnecessary |
| IRF3205PBF | 55 V, 110 A, RDS(on) = 8 mΩ (typ), TO-220 package, legacy design with higher QG (71 nC) | Lower voltage rating unsuitable for 42 V systems; higher gate charge increases driver losses | Suitable only for 12 V/24 V non-automotive applications with ample gate drive strength and thermal margin |
Compared with STP110N10F7 and IRF3205PBF, BUK7619-100B,118 offers automotive-grade reliability in a surface-mount D2PAK package with optimized thermal resistance and avalanche ruggedness - making it the preferred choice for space-constrained, thermally demanding automotive and industrial power switching where qualification and robustness are mandatory.

FAQ
What is the maximum continuous drain current rating for BUK7619-100B,118 at 100 °C mounting base temperature?
The BUK7619-100B,118 supports 45 A continuous drain current at Tmb = 100 °C, as specified in Table 3 of the datasheet. This derating reflects thermal limitations of the D2PAK package and ensures safe operation within the 175 °C maximum junction temperature limit. The BUK7619-100B,118 maintains stable RDS(on) performance up to this temperature due to its TrenchMOS process.
Does BUK7619-100B,118 require a gate resistor for standard automotive microcontroller driving?
Yes - a series gate resistor (typically 10 Ω to 47 Ω) is recommended for BUK7619-100B,118 to control dV/dt and prevent oscillation during switching. The BUK7619-100B,118 has QG(tot) = 53 nC and Ciss = 2555 pF (typ), so a 22 Ω resistor with a 5 V MCU output limits peak gate current to ~230 mA and provides adequate damping. This value is validated in the datasheet's switching time test conditions (RG = 10 Ω).
Is BUK7619-100B,118 pin-compatible with other D2PAK-packaged N-channel MOSFETs?
No - BUK7619-100B,118 uses the standard 3-pin D2PAK (SOT404) outline with G-D-S pin order (Pin 1 = Gate, Pin 2 = Drain, Pin 3 = Source), but pin compatibility cannot be assumed across manufacturers or voltage classes. While physical footprint matches, electrical characteristics (e.g., RDS(on), QG, VGS(th)) differ significantly; PCB layout reuse requires verification of thermal and routing constraints specific to the BUK7619-100B,118's mounting base connection to drain.
What is the significance of the "118" suffix in BUK7619-100B,118?
The "118" suffix in BUK7619-100B,118 denotes the tape-and-reel packaging variant per Nexperia's ordering convention: it indicates 800 units per reel in 24 mm tape width, compliant with EIA-481-D standards. This differs from BUK7619-100B,115 (1,000 pcs/reel) and BUK7619-100B,119 (1,500 pcs/reel). The core die and electrical specs remain identical across all suffix variants.
Can BUK7619-100B,118 be used in high-frequency PWM applications above 100 kHz?
BUK7619-100B,118 supports PWM switching up to ~200 kHz in well-designed layouts, with td(on) = 19 ns, tr = 45 ns, td(off) = 85 ns, and tf = 34 ns. However, efficiency at high frequency depends heavily on gate drive strength and PCB parasitics. The BUK7619-100B,118's QG(tot) = 53 nC and Coss = 340–480 pF mean switching losses rise significantly above 100 kHz unless paired with a low-impedance gate driver and minimized loop inductance.
