| 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 ."
