Description Figure 1. Internal schematic diagram
The STS5DNF20V is a N-channel STripFETTM II. This
Power MOSFET is the latest development of
STMicroelectronics unique "single feature size"
strip-based process. The resulting transistor
shows extremely high packing density for low on-
resistance, rugged avalanche characteristics and
less critical alignment steps therefore a
remarkable manufacturing reproducibility.
