MacMic IGBT Discrete Distributor | G3T and G3U TO-247
Genuine MacMic TO-247 G3T and G3U discrete IGBTs, 650-1350 V, for welding, induction and motor-drive circuits.
MacMic IGBT Discrete Overview
BeiLuo supplies genuine MacMic discrete IGBTs in the TO-247 and TO-247 Plus packages, built on a self-developed low-VCE Trench Field-Stop chip. The product line is split by switching speed: the G3T series targets typical power applications such as motor drive and power conversion below 15 kHz, while the G3U series is tuned for high-speed switching above 15 kHz used in welding machines and induction heating. MacMic discrete IGBTs cover 650 V, 1200 V and 1350 V ratings from 10 A to 120 A, giving design teams a compact alternative to modules for lower-power stages. The TO-247 Plus package extends the current range for high-power single-device designs without paralleling. As an authorized MacMic distributor, BeiLuo ships every discrete with import declaration documents, certificates of origin and RoHS compliance files, and backs the parts with an in-house FAE team. Our engineers help you choose the series by switching frequency, size the gate resistor and dead time, and design the heatsink for reliable operation in welding, induction and motor-drive circuits. Long-term availability and scheduled replenishment keep production lines supplied from prototype through volume. The first decision is G3T versus G3U, followed by voltage class, current and package. Our FAE team helps you size the gate resistor, plan dead time, choose a heatsink and confirm stock lead time, so a discrete design reaches production with the same discipline as a module design.

Frequently Asked Questions
How do I use the discrete IGBT table?
Match VCES to your bus voltage, then use IC and VCE(sat) to compare current capability and conduction loss. The Series column tells you G3T (below 15 kHz) or G3U (above 15 kHz).
Package then decides the mechanical and thermal design.
G3T or G3U: how do I choose the series?
Choose G3T for motor drive and power conversion below 15 kHz where conduction loss dominates. Choose G3U for welding, induction heating and inverters above 15 kHz where switching speed dominates.
Match the series to your switching frequency.
What is the advantage of TO-247 Plus?
TO-247 Plus extends the current range of a single device, so high-power designs avoid paralleling multiple discretes. That simplifies current sharing and improves reliability.
Use it when your current exceeds a standard TO-247 rating.
How do I design the gate drive for these discretes?
Start from the datasheet gate resistor, keep the gate loop short, and add a negative gate supply for high-current devices. Verify turn-off overvoltage at the device terminals.
Our application note covers gate selection and dead time.
Are these discretes stocked and documented?
Mainstream ratings are held in regional warehouses and ship with import, origin and RoHS documents. Availability is confirmed per request.
