Abstract
A diode having an increased diode voltage drop is provided through the use of an extra collector-base contact which is left electrically floating. By leaving the extra collector-base contact electrically floating, a voltage divider effect results which provides an increased voltage drop across the diode without requiring other structural changes nor increased diode current.
