MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200IAXSG1A DS200IAXSG1AAA IGBT Snubber Board protects IGBT modules from damaging voltage transients. This board mounts directly adjacent to the main power IGBT assembly. You will find it suppressing inductive kickback during high-speed switching events. It dramatically extends the operational lifetime of expensive power semiconductors.
Core Technical Specifications
The GE DS200IAXSG1A DS200IAXSG1AAA IGBT Snubber Board measures 27.0 cm in width and 19.0 cm in height. Its board depth equals 4.0 cm including capacitor and resistor components. The total assembly weighs approximately 1.2 kilograms. Six independent snubber circuits populate the board’s surface area. Each circuit protects one IGBT within a three-phase inverter bridge.

Connectors and Bus Bar Interfaces
The GE DS200IAXSG1A DS200IAXSG1AAA IGBT Snubber Board uses heavy-duty ring terminals for all power connections. Two copper bus bars connect the board directly to IGBT collector and emitter terminals. Six 2-pin headers provide gate driver feedback signals to the main control board. Additionally, the board includes one 9-pin connector for integrated thermistor temperature monitoring.
Energy Storage Discharge and Safety
Each snubber capacitor stores approximately 0.49 joules of energy at 1200 VDC. Therefore, this board retains hazardous energy long after power removal. You must wait 5 minutes for all capacitors to discharge fully. The GE DS200IAXSG1A DS200IAXSG1AAA IGBT Snubber Board includes built-in bleed resistors across each capacitor. These resistors discharge the capacitors to safe voltage levels automatically over time. Always verify zero voltage before touching any terminal or wire connection.
Thermal Management and Mounting
This snubber board requires vertical mounting for proper convective cooling airflow. The power resistors generate significant heat during normal drive operation cycles. Maintain at least 5 cm clearance around each resistor body for heat dissipation. Moreover, the GE DS200IAXSG1A DS200IAXSG1AAA IGBT Snubber Board operates from 0°C to +60°C ambient temperature. Use 10 AWG stranded wire for all external power connections. Do not operate the drive with a missing or damaged snubber board installed. Replace the board immediately if any capacitor shows bulging or leakage signs.
