IGBT's for Sale: Modules and Transistors
Key Takeaways
|
Finding the right IGBT transistor or IGBT module can help you get equipment running again without unnecessary delays. Summit Electronics helps buyers source current, obsolete IGBT’s, and hard to find IGBT’s for industrial maintenance, repairs, and production.
Whether you need an IGBT for an inverter, a motor drive, or a power supply, we help with IGBT procurement based on your exact part number and requirements.
What Is an IGBT Transistor?
IGBT stands for insulated-gate bipolar transistor. An IGBT transistor acts as an electrically controlled switch that manages power in high-voltage and high-current circuits.
A signal at its gate controls current flowing between its collector and emitter. By switching that current rapidly, IGBTs help equipment control motors and convert electrical power.
Common applications include:
- Variable-frequency drives that control motor speed.
- Solar inverters.
- Uninterruptible power supplies.
- Welding equipment.
- Industrial heating systems.
- Transportation and traction equipment.
IGBT Transistors and IGBT Modules: What Is the Difference?
A discrete IGBT transistor is an individual semiconductor device housed in its own package.
An IGBT module combines multiple power devices in one assembly. Depending on its design, it may contain IGBTs and companion diodes arranged for a particular circuit.
Buyers need to match both the electrical specifications and the physical connections. An IGBT module with similar voltage and current ratings may still have a different internal circuit, terminal layout, or mounting arrangement.

How Does an IGBT Inverter Work?
An IGBT inverter uses IGBT transistors to switch DC power into a controlled AC output. In a variable-frequency drive, this switching helps adjust the frequency and voltage supplied to a motor, controlling its speed.
IGBT inverter components also appear in solar power systems, backup power equipment, and other power conversion applications.
When replacing an IGBT in an inverter, use the equipment’s specified component or an engineer-approved alternative. Matching voltage and current alone does not establish compatibility.
IGBT Part Number Examples
These IGBT Transistors and Modules illustrate the difference between individual devices and module assemblies. Use your complete manufacturer part number when you request a quote.
- Infineon IKW40N120H3: Discrete IGBT transistor with an anti-parallel diode.
- Infineon IGW40N120H3: Discrete IGBT transistor.
- Mitsubishi Electric CM100DY-24A: IGBT module.
- Mitsubishi Electric CM300DY-24A: IGBT module.
- Mitsubishi Electric CM300DY-24T: IGBT module.
These are reference examples. Availability depends on your exact part number, quantity, and sourcing requirements. Similar part numbers are not automatically interchangeable. Have your engineer or repair technician confirm compatibility before ordering
Buying Tips for IGBT Procurement
Include the Complete Part Number
Provide every letter, number, and suffix from the original component. Small differences can identify different versions or configurations.
If the markings are unclear, include photographs of the component and label, along with the equipment model.
Compare the Full Specifications
Before buying an IGBT transistor or IGBT module, have your engineer or repair technician check:
- Voltage and current ratings under the relevant operating conditions.
- Gate-drive requirements.
- Switching characteristics and losses.
- Package dimensions and terminal positions.
- Cooling requirements and temperature limits.
- Internal circuit configuration and companion diodes.
A higher-rated part is not automatically a better replacement. Check the manufacturer’s datasheet against the original device and circuit requirements.
Confirm Condition and Delivery Requirements
Specify the acceptable condition, date codes, documentation, and delivery deadline when requesting a quote. Explain any inspection, testing, or traceability requirements at the start of the IGBT procurement process.
Sourcing Obsolete IGBT’s and Hard to Find IGBT’s
Industrial equipment can remain in service long after its original components leave production. A discontinued IGBT module or transistor can make an otherwise straightforward repair difficult.
Summit Electronics helps source obsolete IGBT’s and hard to find IGBT’s through our global supply network. We search according to your exact component requirements and communicate availability for your request.
For equipment you plan to maintain for several more years, review spare-part needs with your maintenance team. Planning ahead can reduce the pressure of locating a discontinued IGBT after a breakdown.
Check Heat Problems Before Installing a Replacement
A failed IGBT transistor may be the result of a cooling, overload, or gate-drive problem. Replacing the part without addressing the cause can lead to another failure.
Have your technician inspect the cooling system, heatsink, thermal interface material, and operating conditions according to the equipment manufacturer’s instructions.
