Infineon IGBT Overview

BeiLuo offers genuine Infineon IGBT discrete devices from the TrenchStop H3 family, engineered for high-efficiency switching in motor drives, inverters, welding equipment and uninterruptible power supplies. Infineon IGBTs combine low saturation voltage with fast, soft-switching behavior to minimize losses across a wide operating range. The H3 series supports junction temperatures up to 175 °C, allowing higher power density in compact designs, while the short-circuit-robust gate oxide simplifies drive circuit design. Devices such as the IKW40N120H3 deliver 1200 V / 40 A switching for three-phase industrial inverters, and the IGW75N60H3 provides 600 V / 75 A switching for welding and power conversion stages. As an authorized Infineon distributor, BeiLuo provides full traceability, import declarations and RoHS documentation with every IGBT order, plus FAE guidance on gate resistor sizing, dead-time management and thermal design. Whether you are prototyping a motor drive or ramping a production program, our stock and procurement team supports both sample quantities and volume shipments with competitive pricing. Our application notes cover gate drive circuits, snubber design and parallel operation, helping your engineering team reduce development risk from first bench test to series production. Beyond components, we help with thermal budget reviews, current derating calculations and cross-family migration when a design needs to move between voltage classes, keeping your power stage competitive at every stage of the product lifecycle.

Frequently Asked Questions

How do I read the IGBT table to pick a device?

The table lists Voltage and Current first because they set your power class, then Package, Switching Speed and Temperature decide the mechanical and thermal design. Start by fixing your DC-link voltage, then narrow by current rating.

Once two or three devices remain, compare Vce(sat) and switching losses at your operating frequency.

1200 V versus 600 V: how do I choose a voltage class?

Choose the voltage class from your DC-link: 600 V devices suit lower-voltage inverters and welding stages, while 1200 V devices cover three-phase 380-480 V drives and higher buses. Always leave margin for switching overshoot.

Higher voltage classes usually trade a little conduction efficiency for blocking capability.

What does Switching Speed mean for my inverter?

Switching Speed tells you the practical hard-switched frequency range. Faster devices cut switching loss and magnetics size but demand tighter gate-drive and EMI design.

If your inverter runs below 20 kHz, the H3 family balances losses and ruggedness well.

How do I compare Vce(sat) and switching losses between models?

Conduction loss scales with Vce(sat) multiplied by current and duty cycle, while switching loss scales with frequency. A low Vce(sat) part wins in high-current, low-frequency designs; a fast part wins when frequency is high.

Estimate both terms for your operating point before you decide.

Ask our FAE team to compare losses

Which package and thermal design should I plan for?

Most discrete IGBTs here use the TO-247 package, which mounts to a heatsink with a standard footprint. Plan junction-to-ambient thermal resistance using the 175 °C junction rating.

Our FAE team can review your heatsink choice and current derating.

How do the two IGBT models in the table differ?

The IKW40N120H3 is a 1200 V / 40 A device for three-phase drives and medium-power inverters, while the IGW75N60H3 is a 600 V / 75 A device for higher-current, lower-voltage stages such as welding and UPS power trains.

Pick by voltage class first, then confirm continuous current against your load.

Do I need a freewheeling diode with these IGBTs?

Standard H3 discrete IGBTs benefit from an external freewheeling diode sized for your reverse recovery. Reverse-conducting variants integrate the diode when board space and cost matter more than flexibility.

Our FAE team can recommend a matched diode for your topology.

Ask us to match a diode for your design

Are the IGBTs in the table stocked and documented?

Both the IKW40N120H3 and IGW75N60H3 are normally available from regional stock, with sample quantities shipped quickly. Every order includes import, origin and RoHS documents.
