WebThe breakdown voltage of a MOSFET transistor is increased by reducing the electric field at the gate edge and/or at the field oxide edge. The electric field is reduced by moving the … In their early history, MOSFETs became known for their absence of secondary breakdown. This benefit was due to the fact that ON-resistance increases with increasing temperature, so that part of the MOSFET which is running hotter (e.g. due to irregularities in the die-attachment, etc.) will carry a lower current density, tending to even out any temperature variation and prevent hot spots. Recently, MOSFETs with very high transconductance, optimised for switching operation, have b…
