They can be classified in two groups depending on their breakdown mechanism. temperature temperature IR Fig. 1: Temperature Behavior of Zener and Avalanche Diodes VR Reverse voltage VZ Zener voltage V(BR) Reverse breakdown voltage IR Reverse (leakage) current IF Forward current VF Forward voltage drop IZT Test current ZZ Dynamic resistance TKVZ / αVZ Temperature coefficient For breakdown voltages VZ > ≈ 6 V, Z-diodes are called avalanche diodes. Below the breakdown voltage, a small current – the leakage current – flows through the diode. When the reverse voltage VR reaches the breakdown voltage, the current rises very fast; the breakdown is like an avalanche. The temperature coefficient of avalanche diodes in the reverse direction is positive (Fig. 1: , m). For breakdown voltages VZ < ≈ 6 V, Z-diodes are called Zener diodes. These diodes show a smooth rise of current with increasing reverse voltage VR. The temperature coefficient is negative (Fig. 1: ). In the forward direction, both the Zener and the avalanche diodes have a negative temperature coefficient (Fig. 1: ). The temperature coefficient of the breakdown voltage is shown in some datasheets as TKVZ or αVZ. SELECTOR GUIDE 2/2 THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
