Product details
Overview
BUK7Y53-100B,115 from Nexperia is an AEC-Q101-qualified N-channel TrenchMOS FET in LFPAK (SOT669) package, designed for automotive power switching with 100 V VDS, 24.8 A continuous drain current at Tmb = 25 °C, and 175 °C junction rating-used in engine management, solenoid drivers, and 12–42 V DC-to-DC converters.
For engineers reviewing the BUK7Y53-100B,115 datasheet, BUK7Y53-100B,115 pinout, BUK7Y53-100B,115 application, or BUK7Y53-100B,115 equivalent, key selection criteria include RDS(on) stability over temperature, avalanche energy rating (81 mJ), thermal resistance (1.76 K/W), and gate drive compatibility with standard 10 V logic sources.
Technical Context
This device implements Nexperia's High-Performance Automotive (HPA) TrenchMOS technology to deliver low RDS(on) (40–53 mΩ typ. at 25 °C, ≤138 mΩ at 175 °C) while maintaining robustness under thermally demanding conditions. Its gate threshold voltage (2–4 V) ensures reliable turn-on with standard microcontroller outputs.
The integrated source-drain diode supports freewheeling in inductive loads, with VSD = 0.85–1.2 V at 15 A and trr = 56 ns, enabling fast recovery in transmission control and solenoid drive circuits. Avalanche ruggedness is specified for unclamped single-pulse events up to 81 mJ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - Maximum drain-source blocking voltage for 12/24/42 V automotive systems with margin against load dump transients. |
| ID (continuous) | 24.8 A at Tmb = 25 °C - Sustained current capability for high-power solenoids and motor drivers without forced cooling. |
| RDS(on) | 40–53 mΩ typ. at VGS = 10 V, ID = 10 A, Tj = 25 °C - Low conduction loss enabling <1 W dissipation at 10 A, reducing heatsink requirements. |
| EAS | 81 mJ (unclamped, single-pulse) - Withstands inductive energy spikes during switch-off without external snubbers in engine valve control. |
| Rth(j-mb) | 1.76 K/W - Enables efficient heat transfer to PCB copper or heatsink, supporting >15 A operation at Tmb = 100 °C. |
| QGD | 8.5 nC - Low gate-drain charge minimizes Miller-induced shoot-through risk in half-bridge configurations. |
| tr/tf | 7.8 ns / 7.7 ns - Fast switching reduces transition losses in PWM-based DC-DC converters operating up to 500 kHz. |
Pinout & Package
Package: LFPAK (SOT669), plastic single-ended surface-mounted package with exposed mounting base connected to drain for enhanced thermal performance and mechanical robustness in automotive vibration environments.
| 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 applications like transmission solenoids. |
| 4 | Gate (G) | Single gate input optimized for 10 V standard-level drive; compatible with automotive MCU GPIOs and dedicated gate drivers. |
| Mounting Base (mb) | Drain (D) | Exposed copper pad electrically and thermally connected to drain-serves as primary heat path and high-current return path in PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive safety-critical systems including engine control units and transmission modules per stress test requirements. |
| 175 °C maximum junction temperature | Enables operation in under-hood environments (e.g., near exhaust manifolds) without derating below rated current at elevated ambient temperatures. |
| Low RDS(on) temperature coefficient | RDS(on) increases only ~3.5× from 25 °C to 175 °C (40 → 138 mΩ), ensuring stable current handling across full automotive temperature range. |
| Integrated source-drain diode | Forward voltage 0.85–1.2 V at 15 A enables self-commutated inductive load switching without external freewheeling diodes in compact solenoid drivers. |
| High avalanche energy rating | 81 mJ non-repetitive EAS allows safe operation during inductive turn-off without clamping circuitry in 42 V starter-generator systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N10F7 | 100 V, 220 A pulsed, RDS(on) = 3.2 mΩ @ 10 V - significantly lower on-resistance but larger DFN8 package (5×6 mm) and higher gate charge (QG = 95 nC). | Better suited for high-current, low-duty-cycle applications (e.g., starter relays); less optimal for thermally constrained PCB layouts requiring LFPAK footprint. | Select when minimizing conduction loss dominates design priority and board space permits larger package. |
| IRF3205PBF | 55 V, 110 A, RDS(on) = 8 mΩ @ 10 V - lower voltage rating, TO-220 through-hole package, no AEC-Q101 qualification. | Not suitable for 42 V systems or automotive under-hood use; limited to industrial 24 V DC loads without qualification traceability. | Consider only for cost-sensitive non-automotive prototypes where qualification and 100 V margin are not required. |
Compared with STL220N10F7 and IRF3205PBF, BUK7Y53-100B,115 delivers optimal balance of AEC-Q101 compliance, 100 V rating, LFPAK thermal efficiency, and gate-drive simplicity-making it preferred for production automotive power stages where reliability, footprint, and qualification are mandatory.

FAQ
What is the maximum continuous drain current at 100 °C mounting base temperature?
The BUK7Y53-100B,115 supports 17.6 A continuous drain current at Tmb = 100 °C, as specified in Table 4 of the datasheet. This derating reflects thermal limits of the LFPAK package and ensures safe operation in under-hood environments where PCB temperature rises significantly above ambient.
Is a gate resistor required for reliable switching in automotive applications?
Yes-a series gate resistor (typically 5–22 Ω) is recommended to dampen ringing caused by PCB trace inductance interacting with QGD and Ciss. The device's 8.5 nC QGD and 1100–1467 pF Ciss make it susceptible to oscillation without controlled gate drive impedance, especially in high-di/dt solenoid circuits.
Can this MOSFET be used in synchronous rectification for 42 V automotive DC-DC converters?
No-BUK7Y53-100B,115 is a standard-level gate drive device requiring VGS ≥10 V for full enhancement; it lacks logic-level (≤4.5 V) gate threshold compatibility needed for direct MCU-controlled synchronous rectification. It is suitable as a primary switch, not a low-side synchronous rectifier.
How does the mounting base connection affect PCB layout and thermal design?
The mounting base is electrically connected to the drain terminal and must be soldered to a large copper pour or thermal pad on the PCB. This dual electrical/thermal path requires isolation from other nets and mandates minimum creepage/clearance distances per automotive standards (e.g., ISO 26262). Thermal vias beneath the pad improve heat transfer to inner layers.
