Diode

Electrical diode

Block Screenshot

Description

This component consists of a simple diode parallel with an ohmic resistance (R). The current (I) passing through this component is defined as a function of the voltage across the ports (V):

i = I_ds.(exp(v/V_t)-1) + v/R

where Ids and Vt are the saturation current and the voltage equivalent of temperature, respectively. If the exponent reaches a certain limit (Max exponent for linear continuation), the diode characteristic becomes linear to avoid overflow.

Parameters

  • Saturation current (A)

    Saturation current

    Properties : Type 'vec' of size 1.

  • Voltage equivalent to temperature (Volt)
