What it is

Physicist William Shockley designed at his semiconductor laboratory a four-layer PNPN diode with negative resistance, equivalent to a gateless thyristor, marketed in the late 1950s before being superseded by the DIAC.

What it led to

  • Development of the thyristor and DIAC
  • Solid-state switching circuits
  • Advances in semiconductor power electronics
