The power rating of a Zener diode indicates the maximum power that the diode can safely dissipate. In the formula below, power equals the voltage multiplied by the current. IZM is the maximum current that can flow through the diode, and PZM is the diode’s maximum power dissipation, and VZ is the Zener voltage.
Nexperia data sheets for Zener diodes generally cover a series of products, with each type number having a specified working voltage. These data sheets start with a section “General description” where the package type is given. The following section “Features and benefits” mentions the working voltage range.
Diode Equation for I-V Curve. The I-V curve (diode characteristic curve) can be find by the following no linear equations. This equation is also known as Ideal Equation of Diode or Diode Law. i = I S ( e qv/k T – 1 ) Where: i = Current flowing through the diode; I s = Reverse or dark saturation current (Typical value for silicon is 10-12 Amperes)
The article discusses how to interpret Zener diode datasheet specifications. It covers key parameters such as maximum power dissipation, maximum current rating, zener voltage tolerance, zener resistance, and derating factor.
