ANSWER THE QUESTION Q5

2. A certain zener diode has a maximum power rating of 300 mW at 40 deg Cand a derating factor of 1.4mW/deg C. Determine the maximum power the zener can dissipate at a temperature of 80 deg C. 3. From the datasheet, a 1N4728A zener diode has a ZZ of 10 0. The datasheet gives VZ = 3.3 V at a test current, IZ, of 76 mA. What is the voltage across the zener terminals when the current is 90 mA? When the current is 45 mA?

RG RL 50K 1K 20 Vpk-pk 1 Hz SCR If IGT is 1.16mA, VGT is 0.76V, and RG is set to 6.81%. Compute the actual ac voltage that will activate the SCR. {Do not include the unit, up to 2 decimal places} If IGT is 1.16mA, VGT is 0.76V, and RG is set to 6.81%. Compute the actual ac voltage that will activate the SCR.
