Product details
Overview
BUK9Y113-100E from Nexperia is an AEC-Q101-qualified N-channel logic-level MOSFET in LFPAK56 (SOT669) package, rated for 100 V VDS, 113 mΩ RDS(on) at VGS = 5 V and Tj = 25 °C, 12 A continuous drain current at Tmb = 25 °C, and 175 °C maximum junction temperature - deployed in automotive transmission control and 48 V power switching circuits.
For engineers reviewing the BUK9Y113-100E datasheet, BUK9Y113-100E pinout, BUK9Y113-100E application, or BUK9Y113-100E equivalent, this page delivers verified thermal resistance (Rth(j-mb) = 3.33 K/W), repetitive avalanche rating, true logic-level gate threshold (VGS(th) ≥ 0.5 V at 175 °C), and LFPAK56 mounting-base thermal interface details critical for high-reliability automotive PCB layout and thermal design.
Technical Context
This MOSFET uses TrenchMOS technology to achieve low RDS(on) with robust gate oxide integrity and stable threshold voltage across temperature. Its 175 °C junction rating and Q101 qualification enable direct integration into under-hood modules without derating penalties typical of standard industrial MOSFETs.
The device features a monolithic source-drain diode with 28 ns reverse recovery time and 29 nC recovered charge, supporting efficient synchronous rectification and flyback energy handling in solenoid and motor drive applications. Its gate charge profile (QG(tot) = 8.4 nC, QGD = 3.9 nC) supports fast switching with minimal Miller-induced shoot-through risk at 5 V logic drive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - Maximum drain-source blocking voltage compatible with 48 V automotive systems with 2× transient margin. |
| RDS(on) | 113 mΩ @ VGS = 5 V, ID = 5 A, Tj = 25 °C - Enables <1.2 W conduction loss at 10 A, reducing heatsink requirements. |
| ID (cont) | 12 A @ Tmb = 25 °C - Sustained current capability suitable for high-duty-cycle lamp and solenoid drivers. |
| Ptot | 45 W @ Tmb = 25 °C - High power density enabled by LFPAK56's low Rth(j-mb) = 3.33 K/W. |
| VGS(th) | ≥ 0.5 V @ Tj = 175 °C - Ensures reliable turn-on with standard 3.3 V/5 V microcontroller GPIOs even at extreme under-hood temperatures. |
| EAS | 13.4 mJ - Non-repetitive avalanche energy rating allows safe operation during inductive load switching transients without external snubbers. |
| QGD | 3.9 nC - Low gate-drain charge minimizes switching losses and improves controllability in hard-switched DC-DC and motor phases. |
Pinout & Package
LFPAK56 (SOT669) is a thermally enhanced surface-mount package with exposed mounting base connected to drain, optimized for PCB copper thermal spreading. It provides 3× parallel source leads and single gate terminal for low-inductance, high-current routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source (S) | Three independent source terminals reduce bond-wire inductance and improve current sharing in high-di/dt switching. |
| 4 | Gate (G) | Single gate input with 8.4 nC total gate charge; designed for direct 5 V logic-level drive without level-shifting. |
| Mounting Base | Drain (D) | Exposed copper pad electrically and thermally connected to drain - requires dedicated PCB thermal pad with ≥4 thermal vias for optimal Rth(j-mb). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114, enabling use in safety-critical transmission control modules. |
| Repetitive avalanche rated | Rated for repeated unclamped inductive switching events up to 13.4 mJ, eliminating need for external clamping diodes in solenoid drivers. |
| 175 °C junction rating | Enables full-rated performance in engine bay environments without current derating - unlike standard 150 °C MOSFETs requiring >30 % ID reduction at 125 °C ambient. |
| True logic-level gate | VGS(th) ≥ 0.5 V at 175 °C ensures guaranteed turn-on with 3.3 V MCU outputs, avoiding gate driver ICs in space-constrained ECUs. |
| LFPAK56 thermal performance | Rth(j-mb) = 3.33 K/W enables 45 W dissipation with only 150 °C ΔT - outperforming SO-8 packages by >40 % in thermal resistance. |
Applications
| Transmission Control Valve Driver | 48 V Mild Hybrid Starter Generator Interface |
|---|---|
|
Use Scenario: Driving PWM-controlled hydraulic solenoids in 8-speed automatic transmissions, operating continuously at 125 °C under-hood ambient.

| LED Headlamp Matrix Dimming | Electric Power Steering (EPS) Motor Phase Switch |
|
Use Scenario: Individual channel dimming for adaptive LED headlamps with 24 V supply and 2 A per string, requiring flicker-free 10 kHz PWM. IC Role / Device Role / Timing Role: Low-side constant-current switch with precise duty-cycle control and <10 ns propagation delay tolerance. Use Value: 8.4 nC total gate charge enables fast, predictable turn-on/off with minimal gate drive power; 28 ns trr prevents cross-conduction in multi-string layouts. |

IC Role / Device Role / Timing Role: Inverter half-bridge switch delivering 10 A peak phase current with <500 ns switching transitions and zero fault-induced latch-up. Use Value: AEC-Q101 qualification guarantees lifetime reliability; 3.33 K/W Rth(j-mb) maintains junction temperature below 150 °C even with minimal heatsinking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N10F7 | 100 V, 2.2 mΩ RDS(on) @ 10 V, 220 A rating - significantly lower on-resistance but requires 10 V gate drive and larger DFN5x6 package. | Better suited for high-current traction inverters; not logic-level compatible and lacks Q101 certification in standard grade. | Select when system uses 10 V gate drivers and demands sub-3 mΩ conduction loss - not drop-in for 5 V logic-driven designs. |
| IRF3205PBF | 55 V, 8 mΩ RDS(on) @ 10 V, TO-220 package - lower voltage rating, higher RDS(on), no automotive qualification, and 175 °C rating only in selected variants. | Used in cost-sensitive industrial motor drives; unsuitable for 48 V automotive systems due to insufficient VDS margin. | Consider only for non-automotive 12 V/24 V applications where AEC-Q101 compliance and 100 V rating are not required. |
Compared with STL220N10F7 and IRF3205PBF, BUK9Y113-100E uniquely balances 5 V logic compatibility, 100 V rating, AEC-Q101 qualification, and LFPAK56 thermal efficiency - making it the only viable option for space-constrained, high-temperature automotive switches demanding both reliability and ease of drive.

FAQ
Is BUK9Y113-100E suitable for 48 V battery system switching?
Yes. With 100 V VDS, 113 mΩ RDS(on) at 5 V gate drive, and AEC-Q101 qualification, it supports 48 V nominal systems including ISO 16750-2 load dump transients up to 87 V. Its 175 °C rating ensures uninterrupted operation during sustained high-power events in under-hood locations.
What is the recommended PCB layout for optimal thermal performance?
Use a minimum 25 mm² exposed copper thermal pad connected to the mounting base via ≥4 thermal vias (0.3 mm diameter, filled and plated). Route all three source pins directly to ground plane, keep gate trace short and shielded, and avoid solder mask over the mounting base area to maximize heat transfer to the PCB.
Does BUK9Y113-100E require a gate resistor for automotive PWM applications?
A 5–10 Ω series gate resistor is recommended to dampen ringing caused by PCB trace inductance and prevent false turn-on during high-di/dt events. This value balances switching speed (10–15 ns rise/fall times) and EMI suppression without compromising gate drive strength from standard MCU GPIOs.
Can BUK9Y113-100E replace older SO-8 MOSFETs like IRFZ44N in existing designs?
No direct replacement: IRFZ44N is 55 V, non-automotive, and requires 10 V for full enhancement. BUK9Y113-100E offers higher voltage rating, logic-level drive, and automotive qualification but uses LFPAK56 footprint (SOT669), requiring PCB land pattern revision and thermal pad redesign.
