1. It is the abruptness with which this reverse current ceases which characterises the step recovery diode. 2. But stemming and reversing current losses is proving an enormous task, analysts and company management say. 3. The activation bath is typically a tank of chromic acid with a reverse current run through it. 4. The forward current is very small and becomes equivalent to the reverse current of a conventional diode. 5. Such polarized relays are used on direct-current circuits to detect, for example, reverse current into a generator. 6. This means that a receiving antenna " sees " an image of the antenna but with reversed currents . 7. When diodes switch from forward conduction to reverse cut-off, a reverse current flows briefly as stored charge is removed. 8. The ECM detects the reversed current and an injector pulsation-reduction command is issued bringing the mixture back to lean. 9. Therefore, the carrier distribution in the whole device is governed by a dynamic equilibrium between reverse current and forward current. 10. The reverse current in such a diode is by tunneling, which is also known as the " tunnel effect ."
