WebThe vertical cross-section of a PT IGBT is shown in the figure. It has a p + substrate at the bottom. This forms a pn-junction with n – drift region. The conduction modulation in this junction occurs by injecting minority carriers into the n – drift region. The p + substrate, n – drift and the p + emitter together constitute a BJT. NPT IGBTs are known as symmetrical … WebThe transistor gain is also increased compared to a Si BJT, which can then be traded for a lower base resistance, and hence lower noise.
