WebVRRM is the maximum allowable non-repetitive reverse voltage. There is no standard definition for this term. The specifics describing this limit must be specified in the datasheet if it differs from VR. IF(AV), Maximum Average Forward Current IF(AV) is the maximum allowable average forward current with the case temperature at the specified value. Webwaves, one moving toward the load (the forward wave) and one moving in the opposite direction (the reflected wave). These waves, moving through the transmission line, interfere with one another to produce the standing wave. Each of these waves have a voltage amplitude — the forward voltage V f and the reflected voltage V r. The conceptual ... WebForward voltage, V F is the voltage drop of a diode across A and K at a defined current level when it is forward biased. • Breakdown voltage, V b is the voltage drop across the diode at a defined current level when it is beyond reverse biased level.
