Product details
Overview
BUK7K89-100E from Nexperia is a dual N-channel standard-level MOSFET in LFPAK56D (SOT1205) package, rated for 100 V drain-source voltage, 82.5 mΩ RDS(on) at 10 VGS/25 °C, and qualified to AEC-Q101 for automotive use. It integrates two independent power switches with true standard-level gate drive (VGS(th) > 1 V at 175 °C), enabling direct microcontroller interface in 12 V/24 V/48 V vehicle systems for motor, lamp, and solenoid control.
For engineers reviewing the BUK7K89-100E datasheet, BUK7K89-100E pinout, BUK7K89-100E application, or BUK7K89-100E equivalent, key selection considerations include its dual-channel layout, 175 °C junction rating, repetitive avalanche capability, and thermal resistance of 3.96 K/W (junction-to-mounting base), critical for thermally constrained automotive PCB layouts.
Technical Context
This device implements TrenchMOS technology in a dual-die LFPAK56D package, with physically isolated FET1 and FET2 channels sharing no internal connection-each has dedicated source, gate, and drain terminals. Its standard-level gate threshold (VGS(th) = 1–4.5 V across –55 to 175 °C) ensures compatibility with 3.3 V and 5 V logic without level-shifting circuitry.
The MOSFET supports unclamped inductive switching with 19.5 mJ non-repetitive avalanche energy (ID = 13 A, Vsup ≤ 100 V), and exhibits low dynamic parameters: QGD = 5.3 nC, Ciss = 608–811 pF, and tf = 7.3 ns, enabling high-frequency PWM operation up to several hundred kHz in transmission control and ultra-high-performance power switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V maximum - supports 48 V automotive bus with 2× safety margin against load dump transients. |
| RDS(on) | 61–82.5 mΩ at VGS = 10 V, Tj = 25 °C - enables <1.3 W conduction loss at 5 A continuous current. |
| ID | 13 A continuous at Tmb = 25 °C - usable up to 9 A at 100 °C mounting base temperature per Fig. 2. |
| Tj max | 175 °C - allows operation in under-hood environments without derating below ambient +150 °C. |
| QGD | 5.3 nC - reduces Miller-induced switching delay and improves gate drive efficiency in high-side configurations. |
| Rth(j-mb) | 3.96 K/W - enables 9.6 W dissipation before reaching 175 °C junction at 25 °C mounting base. |
| EAS | 19.5 mJ (non-repetitive) - sustains single-pulse inductive kickback in solenoid and motor phase-leg applications. |
Pinout & Package
LFPAK56D (SOT1205) is a thermally enhanced surface-mount package with exposed copper mounting base and 8 leads, optimized for low Rth(j-mb) and high power density in automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | S1 | Source terminal of FET1 - connects to low-side return path; electrically isolated from S2. |
| 2 | G1 | Gate terminal of FET1 - requires <20 V absolute max; standard-level threshold enables direct MCU drive. |
| 3 | S2 | Source terminal of FET2 - independent return node; enables dual half-bridge or independent load control. |
| 4 | G2 | Gate terminal of FET2 - fully decoupled from G1; supports asynchronous or synchronized dual-channel switching. |
| 5, 6 | D2 | Drain terminals of FET2 - paralleled internally for lower inductance and higher current handling. |
| 7, 8 | D1 | Drain terminals of FET1 - paralleled internally; provides robust high-side or low-side switching node. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent N-channel MOSFETs | Two fully isolated switch channels in one compact LFPAK56D footprint - eliminates discrete dual-MOSFET layout complexity. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD - suitable for engine bay and transmission control modules. |
| 175 °C junction rating | Enables uninterrupted operation in high-ambient environments (e.g., near exhaust manifolds or power inverters) without thermal shutdown. |
| True standard-level gate | VGS(th) > 1 V at 175 °C ensures turn-on with 3.3 V/5 V logic - removes need for external gate drivers in cost-sensitive ECUs. |
| Repetitive avalanche rated | Guaranteed ruggedness against inductive energy during commutation - simplifies snubber design in motor driver and solenoid circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | 60 V VDS, 2.2 mΩ RDS(on), PowerFLAT 5x6 package, 175 °C rated | Lower voltage rating limits use to 24 V systems only; superior RDS(on) benefits high-current, low-voltage battery management. | Select when system bus voltage ≤ 24 V and <2 mΩ on-resistance is required for <100 mW conduction loss at 7 A. |
| ON Semiconductor NTMFS5C675NL | 60 V VDS, 3.8 mΩ RDS(on), SO-8FL package, AEC-Q101 qualified | Single-channel device requiring two units for dual functionality; lacks integrated dual-die thermal coupling advantage. | Choose for designs needing best-in-class RDS(on) per channel at 60 V, where board space permits separate placement and thermal management. |
Compared with STL220N6F7 and NTMFS5C675NL, the BUK7K89-100E uniquely delivers 100 V capability, dual-channel integration, and 3.96 K/W thermal resistance in one AEC-Q101-qualified LFPAK56D package-making it optimal for 48 V mild-hybrid systems and high-temperature transmission control where voltage headroom and thermal density are critical.

FAQ
Is the BUK7K89-100E pin-compatible with other LFPAK56D dual MOSFETs?
No-BUK7K89-100E uses a unique pinout (S1-G1-S2-G2-D2-D2-D1-D1) optimized for dual independent switching. Unlike some competitors' LFPAK56D devices with shared sources or gates, this part maintains full electrical isolation between channels, requiring specific PCB layout validation before substitution.
What is the maximum safe operating frequency for PWM switching with this MOSFET?
Based on dynamic parameters (QGD = 5.3 nC, tf = 7.3 ns, Ciss = 608–811 pF) and thermal limits, reliable PWM operation extends to 500 kHz in forced-air-cooled conditions and up to 200 kHz in sealed automotive enclosures with 3.96 K/W thermal path-provided gate drive strength exceeds 1 A peak.
Does the device include integrated body diode recovery optimization?
Yes-the source-drain diode exhibits trr = 31.6 ns and Qr = 39.1 nC at 25 °C, with soft recovery characteristics confirmed in Fig. 16. This enables efficient synchronous rectification and reduces EMI in flyback and buck-boost topologies without external Schottky assist diodes.
Can BUK7K89-100E be used in high-side switch configurations?
Yes-its standard-level gate (VGS(th) > 1 V at 175 °C) and 20 V VGS rating support high-side operation with bootstrap or charge-pump gate drivers. However, due to lack of integrated gate driver, external level-shifting or floating supply is required for VGS ≥ 10 V when D1/D2 are biased above ground potential.
