Product details
Overview
BUK9C07-65BIT from NXP Semiconductors is an AEC-Q101-qualified N-channel logic-level TrenchPLUS power MOSFET in SOT427 (D2PAK) package, featuring 65 V V(BR)DSS, 6 mΩ RDSon at VGS = 5 V and 25 °C, integrated current-sense transistor with 12068 A/A ID/Isense ratio, and built-in overtemperature protection diodes. It serves as a high-efficiency, current-monitored high-side or low-side switch in automotive power distribution systems.
For engineers reviewing the BUK9C07-65BIT datasheet, BUK9C07-65BIT pinout, BUK9C07-65BIT application, or BUK9C07-65BIT equivalent, key selection criteria include its Kelvin-source layout for accurate RDSon stability, 75 A continuous drain current capability at Tmb = 25 °C, integrated temperature sense diode (VF = 2.9 V at 25 °C), and avalanche ruggedness of 0.605 J under unclamped conditions.
Technical Context
This device implements a trench-gate MOSFET architecture with split-source Kelvin connection (pins 6 and 7) to eliminate source inductance impact on switching and sensing accuracy. The integrated current-sense transistor shares the same die and thermal environment as the main FET, enabling precise real-time current monitoring without external shunts.
It includes monolithically integrated temperature-sense diodes (Visol(FET-TSD) = 100 V isolation) with -5.7 mV/K temperature coefficient, supporting closed-loop thermal management. The device operates within a junction temperature range of −55 °C to 150 °C and supports logic-level gate drive down to 4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 65 V - Maximum drain-source blocking voltage before avalanche onset; enables use in 48 V automotive systems with margin. |
| RDSon | 6 mΩ @ VGS = 5 V, ID = 25 A, Tj = 25 °C - Low conduction loss supports high-current switching with <1.5 W dissipation at 25 A. |
| ID/Isense | 12068 A/A - Precise current mirroring ratio allows ±1% sensing accuracy with appropriate external amplification. |
| QG(tot) | 102.8 nC - Gate charge optimized for fast switching with moderate gate driver strength (e.g., 1–2 A peak). |
| Rth(j-mb) | 0.51 K/W - Thermal resistance from junction to mounting base enables 245 W total power dissipation at Tmb = 25 °C. |
| EDS(AL)S | 0.605 J - Single-pulse unclamped avalanche energy rating ensures robustness against inductive load turn-off transients. |
| VF(TSD) | 2.9 V @ IF = 250 µA, Tj = 25 °C - Forward voltage of integrated temperature sense diode used for real-time die temperature feedback. |
Pinout & Package
SOT427 (D2PAK) plastic single-ended surface-mounted package with 7 leads (one lead cropped); features isolated mounting base, Kelvin source configuration, and thermally enhanced copper tab for direct heatsink attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | G | Gate terminal - referenced to Kelvin source (pin 6); requires low-inductance PCB routing for stable switching. |
| 2 | IS | Current sense output - provides scaled replica of drain current; must be routed away from noisy power paths. |
| 3 | A | Anode of integrated temperature sense diode - connects to external bias circuit for die temperature measurement. |
| 4 | D | Main drain terminal - high-current path; bonded directly to internal die drain metallization. |
| 5 | K | Cathode of integrated temperature sense diode - forms diode pair with pin 3 for ratiometric temperature sensing. |
| 6 | KS | Kelvin source - dedicated low-current return for gate drive and sense circuits; eliminates IR drop error in RDSon and Isense. |
| 7 | S | Main source terminal - carries full load current; connected to power ground plane with minimum trace inductance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | 60 V V(BR)DSS, 2.2 mΩ RDSon @ 10 V, no integrated current sense or temperature diode. | Requires external current sensing and thermal monitoring; suited for cost-sensitive non-automotive industrial use. | Select when highest efficiency at 10 V gate drive is critical and diagnostic integration is unnecessary. |
| Infineon BSC014N06LS6 | 60 V V(BR)DSS, 1.4 mΩ RDSon @ 10 V, no Kelvin source, no integrated sense/thermal diodes. | Lacks diagnostic features; higher RDSon at 5 V gate drive (~4.5 mΩ) limits logic-level compatibility. | Prefer for high-frequency SMPS where ultra-low QG dominates over integrated monitoring needs. |
Compared with STL220N6F7 and BSC014N06LS6, the BUK9C07-65BIT trades slightly higher RDSon for comprehensive on-die diagnostics-enabling functional safety compliance (ASIL-B ready), reducing system-level component count, and simplifying thermal/current feedback loop design in automotive ECUs.

FAQ
What is the purpose of the separate KS (Kelvin source) and S (source) pins?
The KS pin provides a dedicated low-current return path for gate drive and current sense circuitry, eliminating voltage drop errors caused by high-current flow through the main source (S) pin. This ensures accurate RDSon-based current measurement and stable gate threshold control during fast switching, especially critical in PWM-driven motor and lamp loads.
Can the BUK9C07-65BIT be driven directly by a 3.3 V microcontroller GPIO?
No - the gate threshold voltage (VGSth) ranges from 1.0 V to 2.0 V, but achieving specified RDSon ≤7 mΩ requires VGS ≥4.5 V. At 3.3 V, RDSon increases significantly (>20 mΩ), causing excessive conduction loss. A level-shifting gate driver or 5 V GPIO is required for full performance in automotive applications.
How is the temperature sense diode (pins 3 and 5) used in practice?
Pins 3 (A) and 5 (K) form a monolithic diode whose forward voltage (VF ≈ 2.9 V at 25 °C) decreases linearly with temperature (−5.7 mV/K). By biasing the diode with a constant 250 µA current and measuring VF, the die temperature can be calculated with ±1.5 °C accuracy - enabling real-time thermal derating and overtemperature shutdown.
Does the BUK9C07-65BIT require an external flyback diode when driving inductive loads?
No - the device incorporates an integrated body diode rated for 75 A continuous source current and exhibits 0.605 J single-pulse avalanche energy. While it can safely absorb inductive kickback in many solenoid and motor applications, an external Schottky diode is recommended for repetitive high-energy transients or where reverse recovery time (trr = 60.1 ns) must be minimized.
