Class Information
Number: 257/498
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Punchthrough structure device (e.g., punchthrough transistor, camel barrier diode) > Punchthrough region fully depleted at zero external applied bias voltage (e.g., camel barrier or planar doped barrier devices, or so-called "bipolar sit" devices)
Description: Subject matter wherein the active junction and the second junction are sufficiently closely spaced that the depletion region from the active junction due to the built-in potential of the active junction reaches the second junction even in the absence of a reverse bias voltage across the active junction.
