Abstract (en)

[origin: DE4402884C1] The semiconductor element has a number of adjacent cells formed in the body of the semiconductor, acting as a p-emitter zone (1), a n-base zone (2) and a p-base zone (3) in which a n-emitter zone (4) is embedded. At least one p-zone (5) is embedded in the n-emitter zone, providing a ballast resistance, provided with 2 ohmic contacts. One of the contacts acts as an outer cathode metallisation (K), which has no contact with the n-emitter zone, the other acting as a floating contact (K') in ohmic contact with the n-emitter zone.
