Product details
Overview
BUK9K52-60E from Nexperia is a dual N-channel logic-level MOSFET in LFPAK56D (SOT1205) package, rated for 60 V VDS, 55 mΩ RDS(on) at VGS = 5 V and Tj = 25 °C, and qualified to AEC-Q101 for automotive use. It delivers 16 A continuous drain current at Tmb = 25 °C and supports thermally demanding applications up to 175 °C junction temperature.
For engineers reviewing the BUK9K52-60E datasheet, BUK9K52-60E pinout, BUK9K52-60E application, or BUK9K52-60E equivalent, this device is selected for high-reliability 12 V automotive power switching where dual-channel integration, true logic-level gate drive (VGS(th) > 0.5 V at 175 °C), and repetitive avalanche capability are required.
Technical Context
This dual MOSFET integrates two independent N-channel TrenchMOS devices in a single LFPAK56D package with shared thermal base. Each channel features identical static and dynamic characteristics, including matched RDS(on) (47.3 mΩ typ at 25 °C), QGD = 2.3 nC, and Ciss = 544–725 pF, enabling synchronous or independent control in compact space-constrained designs.
Its AEC-Q101 qualification confirms robustness under automotive stress conditions: 175 °C operation, 11.9 mJ single-pulse avalanche energy, and 64 A peak drain current. The true logic-level gate ensures reliable turn-on with standard 3.3 V/5 V microcontroller outputs even at elevated temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum drain-source blocking voltage compatible with 12 V automotive systems with load-dump margin. |
| RDS(on) | 47.3 mΩ (typ) at VGS = 5 V, Tj = 25 °C - Low conduction loss enabling efficient 16 A continuous switching at 25 °C mounting base. |
| ID | 16 A (continuous) at Tmb = 25 °C - Sustained current capability suitable for motor and solenoid drivers without forced cooling. |
| Tj max | 175 °C - Extended thermal rating allows operation in engine bay or transmission control modules without derating. |
| QGD | 2.3 nC - Low gate-drain charge minimizes switching losses and improves EMI behavior in high-frequency PWM applications. |
| Rth(j-mb) | 4.68 K/W - Low junction-to-mounting-base thermal resistance enables effective heat transfer to PCB copper or heatsink. |
| VGS(th) | > 0.5 V at Tj = 175 °C - Guaranteed turn-on with standard logic-level drivers across full automotive temperature range. |
Pinout & Package
LFPAK56D (SOT1205) is a surface-mount, dual-power SO-8 variant with exposed metal mounting base for enhanced thermal performance. Its 8-lead configuration provides separate source, gate, and drain terminals for both FETs with dual drain pins per channel for current sharing and low-inductance layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | S1 | Source terminal of FET1 - referenced ground node for first channel; electrically isolated from S2. |
| 2 | G1 | Gate terminal of FET1 - controls turn-on/off of first channel; requires logic-level drive (≤5 V). |
| 3 | S2 | Source terminal of FET2 - referenced ground node for second channel; electrically isolated from S1. |
| 4 | G2 | Gate terminal of FET2 - independently controllable gate for second channel. |
| 5, 6 | D2 | Drain terminals of FET2 - paralleled for lower inductance and higher current handling on second channel. |
| 7, 8 | D1 | Drain terminals of FET1 - paralleled for lower inductance and higher current handling on first channel. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel integration | Two matched N-channel MOSFETs in one LFPAK56D package reduce board area by ~40% vs discrete SO-8 solutions. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock per AEC standard. |
| Repetitive avalanche rating | Rated for repeated avalanche events up to 175 °C junction temperature, supporting robust fault tolerance in inductive loads. |
| True logic-level gate | VGS(th) remains > 0.5 V at 175 °C, ensuring guaranteed turn-on with 3.3 V or 5 V MCU GPIO without level-shifting. |
| Thermal performance | 4.68 K/W Rth(j-mb) enables 32 W total power dissipation at Tmb = 25 °C - superior to standard SO-8 packages. |
Applications

IC Role / Device Role / Timing Role: High-efficiency half-bridge upper/lower switch with matched RDS(on) and fast switching (tr = 10.1 ns, tf = 9 ns). Use Value: Low QGD (2.3 nC) and Coss (74–89 pF) minimize shoot-through risk and switching losses at 20 kHz PWM frequencies. |
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, 2.2 mΩ RDS(on) at VGS = 10 V; requires 10 V gate drive; not logic-level; TO-263 package. | Higher current density but incompatible with 3.3 V/5 V logic; larger footprint and higher Rth(j-a). | Select only if gate drive ≥10 V is available and board space permits TO-263 mounting. |
| ON Semiconductor NTMFS5C675NL | 60 V, 5.2 mΩ RDS(on) at VGS = 10 V; logic-level capable down to 4.5 V; PowerSO-8 package. | Lower RDS(on) but no AEC-Q101 qualification; limited to industrial temp range (−55 to 150 °C). | Acceptable for non-safety-critical 12 V systems where AEC-Q101 is not mandated and tighter RDS(on) is prioritized. |
Compared with STL220N6F7 and NTMFS5C675NL, BUK9K52-60E uniquely combines AEC-Q101 qualification, true logic-level operation down to 0.5 V VGS(th) at 175 °C, and dual-channel integration in a thermally optimized LFPAK56D package - making it the only drop-in solution for space- and reliability-constrained automotive power stages.

FAQ
Is BUK9K52-60E suitable for 3.3 V microcontroller gate drive?
Yes. Its gate-source threshold voltage exceeds 0.5 V at 175 °C junction temperature, and typical VGS(th) is 1.4–2.1 V at 25 °C. With 3.3 V or 5 V logic-level drive, both channels achieve full enhancement and low RDS(on) across the full automotive temperature range.
What is the maximum continuous current at 100 °C mounting base temperature?
At Tmb = 100 °C and VGS = 5 V, the datasheet specifies 11 A continuous drain current per channel. This derating reflects thermal limits imposed by the 4.68 K/W Rth(j-mb) and 175 °C maximum junction temperature.
Does BUK9K52-60E include integrated body diodes?
Yes. Each channel includes an inherent source-drain diode with VSD = 0.78–1.2 V at IS = 5 A and Tj = 25 °C, and trr = 17.7 ns. These diodes support freewheeling in inductive switching applications such as solenoid and motor control.
Can BUK9K52-60E replace two separate SO-8 MOSFETs in an existing design?
Yes - provided layout accommodates the LFPAK56D (SOT1205) footprint. Its pinout differs from standard SO-8: pins 1–4 are S1/G1/S2/G2, while pins 5–8 are paralleled D2/D2/D1/D1. Thermal and electrical performance exceeds two discrete SO-8 devices due to lower Rth(j-mb) and matched characteristics.
