It has a maximum reverse current of 5mAdc, a maximum power dissipation of 350mW, and an overall current rating of 100mA. In terms of its physical form, the diode measures 125mm x 0.8mm and weighs 0.15g.

Working Principle

The TZM5221C-GS08 functions as a two-terminal, three-layer device. In its simplest form, the diode receives a forward bias voltage at the anode, which causes a current to flow through the diode into the cathode. The cathode side of the diode is also referred to as the "Zener" side, since this is where the energy is stored and the voltage is regulated. When a forward bias voltage is applied to the anode, current will flow through the junction of the diode, causing electrons to flow and holes to appear. As the current increases, so does the number of holes and electrons, and in turn, the voltage drop across the diode. When the voltage reaches the Zener voltage, the breakdown occurs, and the excess much of the current is diverted into the Zener region. This causes additional electrons and holes to be created within the diode, allowing for a reverse current to occur. This reverse current becomes regulated, maintaining the voltage at the desired level.
