The current of each phase leg of the inverter can be monitored through three independent negative DC terminals.

The FSBB20CH60C is a high-performance 600V 20A intelligent power module (IPM), representing the cutting-edge of power electronics integration technology. The module integrates high-voltage IGBT power devices, gate drive circuits, and multiple protection functions into a compact package, significantly simplifying system design and enhancing overall reliability. The FSBB20CH60C is particularly suitable for motor drive applications in consumer electronics, industrial control, and automotive applications, providing high-efficiency, high-power-density solutions.

The FSBB20CH60C module employs advanced packaging technology, integrating six IGBTs and corresponding freewheeling diodes (FWDs) to form a complete three-phase inverter bridge arm. The module has a rated voltage of 600V, a continuous output current capability of 20A, and a peak current of up to 30A, meeting the requirements of medium-power applications. Compared to traditional discrete component solutions, the FSBB20CH60C reduces the number of external components and PCB area through its highly integrated design, thereby lowering system complexity and overall costs.

Key technical features include:

Built-in gate drive circuit: The module integrates an optimised drive circuit to ensure power devices operate in the optimal switching state while reducing electromagnetic interference (EMI).

Comprehensive protection functions: including overcurrent protection, short-circuit protection, over-temperature protection, and under-voltage lockout (UVLO), preventing device damage under abnormal operating conditions.

Low thermal resistance packaging: Utilises high thermal conductivity packaging materials and a well-designed thermal management system to ensure stable operation under high load conditions.

Electrical isolation: Provides excellent electrical isolation between high-voltage and low-voltage circuits, enhancing system safety and interference resistance.

The FSBB20CH60C module typically operates within a temperature range of -40°C to +125°C and is stored within a range of -40°C to +150°C, enabling it to withstand harsh operating environments. The module features a compact packaging design with dimensions specific to the model (please refer to the official data sheet for exact dimensions), making it ideal for deployment in space-constrained applications. This miniaturised design represents ongoing innovation in power module packaging technology, achieving a balance between high power density and excellent thermal performance.

In terms of electrical performance, the FSBB20CH60C delivers outstanding results. Its IGBT employs advanced trench gate technology, featuring low on-state voltage drop (VCE(sat)) and fast switching characteristics, effectively reducing conduction losses and switching losses. The freewheeling diode adopts a fast recovery design with a short reverse recovery time, further minimising energy losses during switching. These features make the FSBB20CH60C particularly suitable for high-frequency switching applications such as inverters, servo drives, and switching power supplies.

Key electrical parameters:

Rated voltage: 600V, suitable for most industrial and consumer electronics applications

Rated current: 20A continuous output current, 30A peak current capability

Switching frequency: Supports up to 20kHz operating frequency, suitable for high-efficiency conversion applications

On-state voltage drop (VCE(sat)): Typical value below 1.8V (actual value varies with conditions), achieving low on-state losses

Switching losses: Optimised IGBT structure ensures low switching losses, enhancing overall system efficiency

The IGBT integrated into the module employs advanced Trench Field Stop technology, achieving an optimised balance between conduction loss and switching loss. This technology significantly reduces conduction voltage drop through a refined trench gate structure, while the optimised field stop layer design enables faster switching speed and lower switching loss, making it particularly suitable for high-frequency applications.

Integrated protection functions:

Overcurrent protection (OCP): Real-time monitoring of output current, with rapid shutdown of the IGBT when exceeding the safety threshold

Short-circuit protection (SCP): Responds within microseconds upon detecting a short-circuit event to protect power devices

Over-temperature protection (OTP): Monitors chip temperature via an internal temperature sensor to prevent thermal runaway

Undervoltage lockout (UVLO): Ensures safe shutdown when the drive voltage is insufficient, preventing the device from operating in an unstable state.

All these protection functions are integrated within the module, eliminating the need for external monitoring circuits, simplifying system design, and enhancing reliability. The response time of the protection circuits has been carefully optimised to effectively prevent device damage while avoiding false triggers that could disrupt normal system operation.
