1. The other diodes would be reverse biased and conduct no current. 2. The collector base junction is reverse biased in normal operation. 3. The other diodes are reverse biased and conduct no current. 4. Reflective switches conduct RF power when the diode is reverse biased and reflect RF power when forward biased. 5. During the negative half-cycle, the base-emitter junction is reverse biased and hence no current flows. 6. Typically, the collector voltage will be higher than the base voltage, and Schottky diode will be reverse biased . 7. Diode logic is implemented by diodes which exhibit low impedance when forward biased and a very high impedance when reverse biased . 8. This might give rise to a large constant current in the reverse direction for a short time while the diode is reverse biased . 9. Metal semiconductor FETs ( MESFETs ) are JFETs in which the reverse biased p n junction is replaced by a metal semiconductor junction. 10. If both inputs A and B are high ( logic 1; near V + ), then the diodes D1 and D2 are reverse biased .
