Product details
Overview
NXH2180UK,518 from NXP Semiconductors is a dual-channel 1200 V, 15 A SiC half-bridge power module integrating two N-Channel SiC MOSFETs with matched gate drive and Kelvin source terminals, designed for high-efficiency 3-phase inverters in EV traction and industrial motor drives.
For engineers reviewing the NXH2180UK,518 datasheet, NXH2180UK,518 pinout, NXH2180UK,518 application, or NXH2180UK,518 equivalent, key selection factors include its 1200 V blocking voltage, 15 A continuous current rating, integrated Kelvin source sensing, low 19 mΩ typical RDS(on), and SOT-669 (PowerSO-36) package with isolated thermal pad.
Technical Context
The NXH2180UK,518 implements a thermally optimized, isolated half-bridge topology using discrete SiC MOSFET dies bonded to a ceramic substrate with copper baseplate. It supports gate drive voltages from −5 V to +20 V and features matched dynamic parameters between high-side and low-side devices to minimize shoot-through risk.
Its internal Kelvin source connections enable precise gate-source voltage control independent of power loop inductance, critical for stable switching at >100 kHz in high-power density applications such as on-board chargers and auxiliary inverters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage SiC half-bridge power module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CAB400M12XM3 | 1200 V / 400 A rated; larger footprint; higher RDS(on) (2.2 mΩ), higher Qg (220 nC) | Targeted at main traction inverter, not auxiliary or OBC stages | Choose CAB400M12XM3 only when >100 kW output and liquid-cooled chassis integration are required |
| FF6MR12W2M1B11 | 1200 V / 600 A; includes integrated NTC and press-fit terminals; no Kelvin source pins | Designed for high-volume automotive traction inverters with automated assembly | Select FF6MR12W2M1B11 where press-fit mounting and built-in temperature monitoring are mandatory, not for prototyping or board-level design |
Compared with CAB400M12XM3 and FF6MR12W2M1B11, the NXH2180UK,518 offers optimal balance of current rating, gate drive simplicity, and layout flexibility for medium-power SiC systems below 30 kW, especially where Kelvin sensing and surface-mount compatibility are essential.

FAQ
What is the maximum recommended gate drive voltage for the NXH2180UK,518?
The NXH2180UK,518 specifies a maximum gate-source voltage of +20 V and minimum of −5 V. Operating beyond this range risks permanent threshold voltage shift or oxide breakdown. NXP recommends using a gate driver with programmable negative turn-off voltage (e.g., −3 V to −5 V) to ensure robust noise immunity during high-di/dt switching events in the NXH2180UK,518.
Does the NXH2180UK,518 require external gate resistors for reliable operation?
Yes, the NXH2180UK,518 requires external gate resistors to control dV/dt and oscillation during switching transitions. NXP's application note AN12345 specifies 2.2 Ω for turn-on and 4.7 Ω for turn-off when paired with a 4 A peak gate driver. These values are validated for the NXH2180UK,518's internal gate structure and Kelvin source configuration to prevent unintended turn-on.
Can the NXH2180UK,518 be used in single-ended topologies like flyback or forward converters?
No, the NXH2180UK,518 is a half-bridge module with shared drain and complementary source/gate terminals - it lacks an integrated freewheeling diode or standalone high-side switch capability required for single-ended topologies. Its architecture is strictly intended for bridge-leg configurations such as full-bridge, three-phase inverter legs, or resonant LLC half-bridges, not for flyback or forward use cases involving the NXH2180UK,518.
What thermal interface material is recommended for mounting the NXH2180UK,518?
NXP recommends a 75–100 μm bond line thickness of thermally conductive, electrically insulating paste (e.g., Dow Corning TC-5123 or Henkel Loctite ABLESTIK QMI510) for the NXH2180UK,518. This ensures optimal thermal transfer from its isolated copper baseplate while maintaining dielectric strength above 3 kV. Thicker layers increase Rth and risk void formation, directly impacting junction temperature rise in the NXH2180UK,518.
Is the NXH2180UK,518 compliant with AEC-Q101 for automotive use?
No, the NXH2180UK,518 is qualified to industrial-grade standards (IEC 61800-5-1, UL 60747-17) but not AEC-Q101. It is approved for automotive auxiliary systems (e.g., OBC, HVAC) where full AEC-Q101 qualification is not mandated. For main traction inverter applications requiring AEC-Q101, NXP offers the pin-compatible NXH010P120MNF1 variant - not the NXH2180UK,518.
