Product details
Overview
BUK9C10-65BIT from Nexperia is an AEC-Q101-qualified N-channel TrenchPLUS logic-level power MOSFET in SOT427 (D2PAK) package, featuring 65 V VDS, 8.5 mΩ RDS(on) at VGS = 5 V and 25 °C, integrated current-sense transistor (ID/Isense = 8993 A/A), and on-die temperature sense diode. It serves as a high-current, low-loss switching element in automotive-grade power distribution and motor drive circuits.
For engineers reviewing the BUK9C10-65BIT datasheet, BUK9C10-65BIT pinout, BUK9C10-65BIT application, or BUK9C10-65BIT equivalent, this device is selected for its combination of logic-level gate drive compatibility, Kelvin source (KS) and current sense (IS) terminals for precision control, thermal protection capability, and rugged unclamped avalanche rating (0.214 J).
Technical Context
This MOSFET uses Nexperia's TrenchPLUS technology to achieve ultra-low on-resistance while maintaining robust short-circuit and avalanche performance. Its dual-source configuration-separate power source (S) and Kelvin source (KS)-enables accurate gate drive referencing and minimizes PCB layout-induced gate oscillation.
The integrated current-sense transistor provides a stable, temperature-compensated ID/Isense ratio (8094–9892 A/A), and the on-die temperature sense diode delivers a linear −5.7 mV/K coefficient with 2.9 V forward voltage at 25 °C, enabling real-time junction temperature monitoring without external sensors.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | 60 V VDS, 1.2 mΩ RDS(on) at 10 V, no integrated current sense or TSD; TO-263 package. | Lacks analog telemetry; requires external sensing for diagnostics; better suited for fixed-voltage, high-efficiency SMPS rather than automotive functional safety systems. | Select when lowest possible RDS(on) is critical and telemetry is handled externally. |
| Infineon BSC014N06LS6 | 60 V VDS, 1.4 mΩ RDS(on) at 10 V, no IS or TSD pins; PG-TDSON-8 package. | No Kelvin source or current sense; smaller footprint but higher thermal resistance (Rth(j-a) = 40 K/W vs. 0.73 K/W to base); unsuitable for >30 A continuous without forced air. | Select for space-constrained consumer applications where AEC-Q101 and telemetry are not required. |
Compared with STL220N6F7 and BSC014N06LS6, the BUK9C10-65BIT trades modestly higher RDS(on) for integrated diagnostics (IS, TSD), Kelvin source architecture, and AEC-Q101 validation-making it uniquely suitable for ASIL-B automotive power switches where functional safety and field diagnostics are mandatory.

FAQ
What is the purpose of the Kelvin source (KS) pin?
The KS pin provides a dedicated low-inductance return path for the gate drive loop, decoupling gate-source voltage sensing from high-current source lead voltage drops. This ensures accurate VGS control during fast switching (di/dt > 100 A/µs), preventing false turn-off and oscillation-critical in motor and solenoid drive applications.
How is the current sense ratio (ID/Isense) used in practice?
With a typical ratio of 8993 A/A, a 1 mA sense current corresponds to ~9 A drain current. Designers place a precision resistor (e.g., 100 Ω) between IS and S to generate a 100 mV/A scaling, yielding 0.9 V output at 9 A-enabling direct ADC interfacing for real-time current monitoring without amplification or calibration drift.
Does the BUK9C10-65BIT require a gate resistor for stability?
Yes-a 10 Ω external gate resistor is recommended per the datasheet's switching characterization (RG(ext) = 10 Ω). This value damps gate ringing caused by LS/LD parasitics and controls dv/dt to meet CISPR 25 Class 5 EMI limits in automotive applications, especially when driving inductive loads.
Can the temperature sense diode be used for overtemperature shutdown?
Yes-the diode's forward voltage decreases linearly at −5.7 mV/K, allowing microcontroller-based junction temperature calculation using two-point calibration. When combined with the IS pin, it enables coordinated thermal-current derating: e.g., reduce PWM duty cycle if Tj exceeds 135 °C while load current remains above threshold.
