At 298 K, the nominal Zener voltage is found to be equal to 10 V. Given that the value of the temperature coefficient is 0.072 (%/K), what is the nominal Zener Voltage at 398 K?(a) 9.46 V(b) 9.54 V(c) 0.54 V(d) 10.54 VI had been asked this question in class test.I want to ask this question from Types of Diode and their Testing in chapter Diode Circuit of Analog Circuits |

Answer» CORRECT ANSWER is (d) 10.54 V Explanation: The change in VZ with temperature is calculated from the FOLLOWING equation: Change in VZ = TC.VZ(T1 – T0))/1000 Change in VZ = 0.54 V Now, as the VALUE of T is POSITIVE, new VZ = 10 + 0.54 V = 10.54 V. |
