41. This feature provides better surge protection than simple Zener diode and acts more like a gas discharge tube replacement. 42. Pro Electron naming for transistors and Zener diodes has been widely taken up by semiconductor manufactures around the world. 43. Ellie goes to the Buy More, where Lester is testing Jeff's extrasensory perception with Zener cards. 44. This also relates to series resistors for zener diode voltage references that is affected by input voltage and temperature. 45. This circuit lowers the output voltage by a quantity that is equal to the Zener diode's breakdown voltage. 46. Resistor, R1, supplies the Zener current and the base current ( ) of NPN transistor ( Q1 ). 47. This can be achieved by putting a zener diode between the cathode and ground or using a separate bias supply. 48. :Any design will surely involve Zener diodes and at least one Operational amplifier, and resistors, of cours. 49. Use of the IEC or EIA E series is mostly restricted to resistors, capacitors, inductors and Zener diodes. 50. This is different from a Zener diode, which will stop conducting once the reverse voltage drops below the breakdown voltage.
