“…Another cause of avalanche operation, more specific to the automotive environment, is the loaddump [4], [5], which is a spurious battery disconnection while it is being charged by the alternator. If this occurs, there is no more device to limit the vehicle network voltage and absorb the current generated by the altemator.…”

“…Due to intrinsic instability of low-voltage power MOSFETs in a saturated region [4], the only way to clamp alternator output voltage is to use low breakdown voltage transistors. Body diodes of the transistors will therefore have to sustain avalanche during several hundreds of milliseconds, until demagnetization of the alternator [5]. The avalanche operation of the body diode remains nondestructive, given adequate thermal conditions.…”

This letter addresses the behavior of low voltage power MOSFETs under avalanche, with a paralleling point of view. It is shown that during avalanche, up-to-date technology MOSFET transistors exhibit a resistance far in excess of their on-state resistance . A novel test setup is proposed to measure "avalanche" resistance. A simple model of breakdown voltage is then proposed. It becomes possible to perform fast simulations using this model to study current balance between paralleled transistors under avalanche operation. It is shown that considering avalanche resistance reduces the influence of breakdown voltage mismatches and allows for better current sharing.
