Assume that the Zener diode has a constant reverse breakdown voltage for a current range, starting from a minimum required Zener current, $I_{Z min}=2\:mA$ to its maximum allowable current. The input voltage $V_{I}$ may vary by $5\%$ from its nominal value of $6\: V$. The resistance of the diode in the breakdown region is negligible. The value of $R$ and the minimum required power dissipation rating of the diode, respectively, are $186\:\Omega$ and $10\:mW$ $100\:\Omega$ and $40\:mW$ $100\:\Omega$ and $10\:mW$ $186\:\Omega$ and $40\:mW$ Electronic Devices gate2018-ec electronic-devices zener-diode + – gatecse 468 views answer comment Share Follow Add Sync Questions Print 0 reply Please log in or register to add a comment.
