Product details
Overview
BUK7Y113-100EX from Nexperia is an AEC-Q101-qualified N-channel standard-level MOSFET in LFPAK56 (SOT669) package, rated for 100 V drain-source voltage, 113 mΩ RDS(on) at 10 VGS/25 °C, and 175 °C junction temperature. It serves as a high-reliability power switch in automotive transmission control, lamp/solenoid drivers, and 12–48 V systems requiring repetitive avalanche capability and thermally robust operation.
For engineers reviewing the BUK7Y113-100EX datasheet, BUK7Y113-100EX pinout, BUK7Y113-100EX application, or BUK7Y113-100EX equivalent, key selection criteria include its 100 V VDS, 113 mΩ RDS(on) at 5 A/25 °C, Q101 qualification, 175 °C Tj rating, and LFPAK56 thermal performance with Rth(j-mb) = 3.33 K/W.
Technical Context
This MOSFET uses TrenchMOS technology to deliver stable threshold voltage (VGS(th) > 1 V at 175 °C) and low on-resistance while maintaining ruggedness against unclamped inductive switching. Its gate drive is compatible with standard 10 V logic, eliminating need for level-shifting in 12 V/24 V automotive microcontroller interfaces.
The device integrates a source-drain diode with 31 ns reverse recovery time and 37 nC recovered charge, enabling efficient freewheeling in inductive load switching. Its 13.4 mJ non-repetitive avalanche energy rating supports reliable operation under transient overvoltage conditions without external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - Maximum continuous drain-source blocking voltage for 12 V/24 V/48 V automotive bus protection |
| RDS(on) | 113 mΩ @ 10 VGS, 5 A, 25 °C - Enables <1.1 W conduction loss at 5 A, reducing heatsink requirements |
| ID | 12 A @ Tmb = 25 °C - Supports sustained current in motor driver half-bridges and solenoid actuators |
| Ptot | 45 W @ Tmb = 25 °C - High power density enabled by LFPAK56 mounting base thermal path |
| Rth(j-mb) | 3.33 K/W - Direct junction-to-mounting-base thermal resistance enables efficient PCB copper pour cooling |
| QGD | 4.2 nC - Low gate-drain charge minimizes Miller-induced switching oscillation in high-dV/dt environments |
| EAS | 13.4 mJ - Rated unclamped avalanche energy supports robustness during inductive turn-off transients |
Pinout & Package
LFPAK56 (SOT669) is a 4-lead plastic surface-mount package with exposed mounting base electrically connected to the drain. Its low-profile design (max height 1.20 mm) and optimized copper slug enable superior thermal transfer to PCB copper planes compared to SO-8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source (S) | Three parallel source terminals reduce bond wire inductance and improve current sharing in high-di/dt switching |
| 4 | Gate (G) | Single gate input with 10 V standard-level threshold; compatible with 3.3 V/5 V MCU GPIO when driven with sufficient current |
| Mounting Base | Drain (D) | Exposed copper pad tied directly to drain; provides primary thermal path and must be soldered to large PCB copper area for rated power dissipation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability across -55 °C to +175 °C operating range, including temperature cycling and HTRB |
| Repetitive avalanche rated | Guaranteed operation under repeated inductive switching stress without degradation, critical for transmission solenoid drivers |
| True standard-level gate | VGS(th) > 1 V at 175 °C ensures predictable turn-on margin even at maximum junction temperature |
| 175 °C junction rating | Enables placement near heat sources (e.g., engine bay ECUs) without derating or forced cooling |
| Low QGD/QG ratio | 4.2 nC / 10.4 nC = 0.40 - Reduces risk of false turn-on during high-speed switching in noisy automotive environments |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | 60 V VDS, 1.2 mΩ RDS(on), PowerFLAT 5x6 package, no AEC-Q101 certification | Not suitable for 48 V or 100 V bus systems; limited to 24 V applications with lower voltage margin | Select only for cost-sensitive 24 V non-safety-critical loads where Q101 is not mandated |
| IRF1010NSPBF | 100 V VDS, 12 mΩ RDS(on), TO-220 package, no AEC-Q101, 175 °C rating | Requires mechanical mounting and heatsink; unsuitable for automated SMT assembly or space-constrained modules | Choose only for prototyping or legacy through-hole designs where LFPAK56 reflow is unavailable |

FAQ
Is BUK7Y113-100EX pin-compatible with other LFPAK56 MOSFETs?
Yes-BUK7Y113-100EX uses the standard SOT669 footprint with pins 1–3 as source, pin 4 as gate, and mounting base as drain. This matches all Nexperia LFPAK56 N-channel MOSFETs (e.g., BUK7K17-60E), enabling drop-in replacement within the same voltage/current class when thermal and RDS(on) requirements align.
What is the maximum continuous drain current at 100 °C mounting base temperature?
Per Figure 1 in the datasheet, the continuous drain current is 8.5 A at Tmb = 100 °C and VGS = 10 V. This derating reflects thermal limits of the LFPAK56 package and must be respected in PCB layout with adequate copper area for heat spreading.
Does BUK7Y113-100EX require a gate resistor for automotive EMI compliance?
Yes-a gate resistor (typically 5–22 Ω) is recommended to control dV/dt and suppress ringing during switching. The 4.2 nC QGD and 10.4 nC QG(tot) values indicate moderate gate drive strength; pairing with a 10 Ω resistor achieves ~100 ns rise/fall times suitable for most 20–100 kHz automotive power stages.
Can BUK7Y113-100EX be used in synchronous rectification topologies?
Yes-it supports synchronous rectification in buck, boost, and buck-boost converters up to 100 V input. Its 31 ns trr and 37 nC Qr allow efficient reverse recovery in 100–500 kHz operation, but dead-time must exceed 50 ns to prevent shoot-through given its 7.7 ns td(off) and 5.9 ns tf.
