FNB40560B2

Overview

The FNB40560B2 is a Motion SPM 45 series power module designed for AC Induction, BLDC, and PMSM motor applications. It integrates a 600V, 15A three-phase IGBT inverter with optimized gate drive circuitry to minimize electromagnetic interference and energy loss. The module features a ceramic substrate for low thermal resistance and includes built-in protection mechanisms such as under-voltage lockout, over-current protection, and thermal monitoring via an NTC thermistor. It utilizes a single grounded supply for logic control and offers independent emitter pins for precise current sensing.

Procurement Notes

Verify component authenticity through authorized onsemi distributors or direct channels. Confirm the specific ordering suffix matches the required package variant. Check current lifecycle status, as availability may vary. Ensure storage conditions comply with semiconductor handling standards to prevent moisture sensitivity issues prior to assembly.

Selection Notes

Select this module for applications requiring integrated gate drive and protection in a compact form factor. Evaluate thermal management requirements based on the ceramic substrate's heat dissipation capabilities. Consider the 600V voltage rating and 15A current capacity against peak load demands. Verify compatibility with single-supply logic interfaces and ensure PCB layout supports the independent emitter connections for accurate current feedback.
