The slides are the product of many rounds of teaching With some hand waving, we can say electrons can easily flow from n regions to p regions, as long as they have a little force (voltage) to push them. But flowing from a p region to an n region is really hard (requires a lot of voltage). This is not the case for the zener diode. With the incorporation of an additional transistor and two clamping diodes on the primary side of the transformer of the isolated Zeta converter, an isolated two-transistor Zeta converter is proposed. But the special thing about a transistor -- the part that makes our two-diode model obsolete -- is the fact that electrons can easily flow from the p-type base JEDEC Coding System Table for Diodes and Transistors - Free download as PDF File (. Diodes A diode has a very non-linear I-V characteristic given by (/ 1) =0 − I I eeV kBT (1) where V is the voltage across the diode, T is the temperature in Kelvin, e is the charge of the electron, kB is Boltzman’s constant, and I is the current passing through the If the transistor is replaced with two diodes connected back-to-back, we get, 1 k 1 k B 5 V E 10 V D1 D2 C I3 R I1 I2 1 R2 Assuming Von = 0:7 V for D1, we get I1 = 5V 0:7V R1 = 4:3 mA, I2 = 0 (since D2 is reverse biased), and I3 ˇI1 = 4:3 mA.
