ST brought out a single component with this configuration called Emitter switched bipolar transistor. Sold for just a few years then was obsoleted. | |

Of course they have now been displaced by power MOSFETs and IGBTs | |

I guess because the main use now is AC where you can get away with thyristors and GTOs are not needed? | |

| Feb 6, 2020 at 11:13 | comment | added | Ken Grimes | GTOs weren't niche, they were very mainstream back in the days, they were just replaced by better devices (power MOSFETs and IGBTs) | |
| Feb 6, 2020 at 5:05 | comment | added | DKNguyen | Doesn't sound any different than what happens to any niche variant of a device, like double gate MOSFETs or Gate Turn Off Thyristors. There was also funny device I can't quite remember that I think was like a BJT with some other transistor in series with its source and was meant to keep it just out of saturation or something like that for faster switching. I can't quite remember. Does this RB-IGBT accomplish anything that a regular IGBT with a series diode cannot? Because reading around it sounds like it can't, which would explain why you can't find one. | |
