REVERSE RECOVERY TIME: Reverse recovery time, denoted by trr . If the applied voltage should be reversed to establish a reverse-bias situation, we would ideally like to see the diode change instantaneously from the conduction state to the nonconduction state. Diode current will simply reverse as shown in Fig. 1.29 and stay at this measurable level for the period of time ts (storage time) required for the minority carriers to return to their majority-carrier state in the opposite material. The current will reduce in level to that associated with the nonconduction state. This second period of time is denoted by tt (transition interval). This is an important consideration in high speed switching applications. Most commercially available switching diodes have a trr in the range of afew nanoseconds to 1 s (Schottky diode).

10. ZENER DIODES Zener diodes are available having Zener potentials of 1.8 to 200 V with power ratings from to 50 W. There is a slight slope to thegharacteristics requiring the piecewise equivalent model appearing in Fig.(1-20) for zener region, while it is assumed as ideal with a straght vertical line at the zener potential.
