9:41 AM bbcsulb.desire2learn.com T-Mobile LTE 1. Look up the following parameters for the IN4735 breakdown diode Nominal Breakdown voltage, V Dissipation Typical Tempco at Izr 2.5 mV/C. Typical Knee Current Iz 10 mA. V. 2. Referring to Figure 1, determine the power dissipated in Rs at Izr. The 1/2 W rating offers a tradeoff between the physical size of the resistor and its temperature rise in the circuit. 100(1/2w) V,-6.2v Figure I Circuit to Measure Breakdown Characteristics ine the Copy Look Up Sh are... Vs, vary between 1.6 V ·5 Vz without exceeding 1 /4 W dissipation in Rs and still allowing I, > 3 mA. Select a resistance from the standard nominal 10% resistance values listed below. The resistance should be the standard value which is appropriately higher or lower than the calculated one. 1.0 2.2 4.7 With multiples of 1, 10, 100, 1000 1.2 2.7 5.6 1.5 3.3 6.8 1.8 3.9 8.2 10,000, 100,000, 1,000,000. Powor SupplyExplanation / Answer
1. For IN4735 Vz= 6.2V @ Iz= 41mA. Dissipation= Vz*Iz= 6.2 * 41* 10-3= 254.2mW.
2. in fig 1 : IZT= 41mA and this current will be flowing through series resistor Rs as well. Rs = 100 ohms. Hence power at Iz can be given as = I2ZT * Rs Watts= 41*41*100*10-6 W= 1.68 W
