- LargoLasskhyfv 1y agoBecause they contain long cascades of these https://en.wikipedia.org/wiki/Insulated-gate_bipolar_transistor https://en.wikipedia.org/wiki/Insulated-gate_bipolar_transis... to be arranged into these https://en.wikipedia.org/wiki/Power_electronics https://en.wikipedia.org/wiki/Power_electronics
- mppm 1y agoAs a sibling comment implies, high-power IGBTs are still built from small and thin silicon dies with most of the module being heat spreader, insulator, interconnect and packaging. Even MW-class modules probably contain a gram or so of Si.
