Product details
Overview
BUK7Y13-40B,115 from Nexperia is a standard-level N-channel TrenchMOS FET in LFPAK (SOT669) package, designed for automotive-critical switching of 12 V loads. It delivers 58 A continuous drain current at 25 °C mounting base temperature, features 11–13 mΩ RDS(on) at VGS = 10 V and Tj = 25 °C, supports 175 °C junction operation, and is AEC-Q101 qualified for airbag, ABS, and fuel injection systems.
For engineers reviewing the BUK7Y13-40B,115 datasheet, BUK7Y13-40B,115 pinout, BUK7Y13-40B,115 application, or BUK7Y13-40B,115 equivalent, this part is selected for thermally demanding automotive power switching where gate drive compatibility with standard 10 V logic, avalanche ruggedness (85 mJ), and low thermal resistance (1.8 K/W) are essential design requirements.
Technical Context
This FET uses Nexperia's High-Performance Automotive (HPA) TrenchMOS technology to achieve stable RDS(on) across -55 °C to +175 °C junction temperature range and robust unclamped inductive switching performance. Its 40 V VDS rating and 25 mΩ RDS(on) at 175 °C enable reliable operation under worst-case thermal conditions in engine bay environments.
The device integrates a source-drain diode with 0.85–1.2 V forward voltage at 25 A and exhibits fast dynamic behavior: 9 ns turn-on delay, 25 ns rise time, 35 ns turn-off delay, and 27 ns fall time under 10 Ω gate drive. Its 983–1311 pF Ciss and 138–189 pF Crss support predictable gate driver sizing for PWM control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V - Maximum drain-source blocking voltage; defines safe operation in 12 V automotive systems with load dump transients. |
| RDS(on) | 11–13 mΩ @ VGS = 10 V, ID = 25 A, Tj = 25 °C - Low conduction loss enabling high-efficiency switching of motors and solenoids. |
| ID | 58 A @ Tmb = 25 °C - Continuous current capability at standard heatsink interface temperature. |
| Ptot | 85 W @ Tmb = 25 °C - Total power dissipation limit; combined with 1.8 K/W Rth(j-mb), enables precise thermal design. |
| EAS | 85 mJ (non-repetitive) - Unclamped avalanche energy rating; ensures robustness against inductive kickback in relay and motor drive circuits. |
| QGD | 5 nC - Gate-drain charge determining Miller plateau duration and switching loss during hard-switching transitions. |
| Tj max | 175 °C - Maximum junction temperature; allows operation in high-ambient under-hood locations without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive power FET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N4F7AG | 40 V, 220 A rated, 0.75 mΩ RDS(on) @ 10 V, but requires 15 V gate drive for full enhancement; larger PowerFLAT 5x6 package. | Targeted at higher-current traction inverters; over-specified for 12 V body electronics. | Select when system demands >100 A peak current and can support 15 V gate bias. |
| ON Semiconductor NTMFS4C09NT1G | 40 V, 75 A, 9.5 mΩ RDS(on) @ 10 V, AEC-Q101 qualified, same LFPAK56 (SOT669) footprint. | Lower RDS(on) improves efficiency but reduces avalanche margin (EAS = 52 mJ). | Prefer for thermally constrained ECUs where conduction loss dominates over transient robustness. |
Compared with STL220N4F7AG and NTMFS4C09NT1G, the BUK7Y13-40B,115 offers balanced trade-offs: sufficient current (58 A), proven 85 mJ avalanche ruggedness for safety-critical loads, and guaranteed 10 V gate compatibility-making it optimal for cost-sensitive, space-constrained automotive body control modules.

FAQ
Is BUK7Y13-40B,115 suitable for 12 V battery reverse-polarity protection?
No. As an N-channel standard-level FET, it requires gate drive referenced to source potential-making it unsuitable for high-side reverse-polarity protection without complex charge-pump circuitry. P-channel alternatives like PMV30UN2 are recommended for that topology.
What is the maximum allowable gate-source voltage for BUK7Y13-40B,115?
The absolute maximum VGS is ±20 V per datasheet Table 4. Operation above 12 V does not improve RDS(on) significantly beyond 10 V, and sustained use near 20 V risks accelerated gate oxide degradation-designs should clamp gate drive at 12–15 V with appropriate Zener protection.
Does BUK7Y13-40B,115 require a gate resistor for automotive PWM applications?
Yes. A 10 Ω external gate resistor is specified in the datasheet for switching characterization (e.g., Figure 14). This value balances EMI suppression and switching speed; lower values increase dI/dt and risk oscillation, while higher values raise switching losses disproportionately in high-frequency (>5 kHz) PWM solenoid control.
Can BUK7Y13-40B,115 be paralleled with identical units for higher current capacity?
Yes, but only with matched layout: symmetrical PCB routing, shared thermal pad, and individual gate resistors. The device's positive RDS(on) temperature coefficient (Figure 12) enables inherent current sharing-but mismatched thermal paths or gate drive skew will cause imbalance, especially above 80 °C ambient.
