BARITT Diode Breakdown Voltage Calculator and Formula

This page explains the BARITT diode breakdown voltage calculator and provides the relevant formula. It also touches upon how to calculate the electric field within a BARITT diode.

EXAMPLE:

• INPUTS: Er = 11.8, N = 2.8E21 m^-3, L = 6 µm
• OUTPUTS: Vbd = 154.36 Volts, Ebd = 2.57 x 10^7 V/meter

BARITT Diode Breakdown Voltage Formula

The following equation is used to calculate the BARITT diode breakdown voltage. You can also derive the breakdown electric field from the breakdown voltage.

Where:

• εs = ε0 x εr
• q = 1.6 x 10^-19 (elementary charge)
• N = Donor Concentration
• L = Silicon Length
• ε0 = 8.854 x 10^-12 (permittivity of free space)
• εr = Relative dielectric constant
