  1. Zener Diode and Zener Regulator Electronic Design Laboratory

  2. Overview • Reverse Breakdown • Specification • Zener Diode I-V Characteristics • Thermal Characteristics • Regulation of Zener Regulator

  3. Avalanche Effect • Acceleration in electric field • Impact-ionization process

  4. Zener Effect • Heavily doped diode • Narrow depletion region • Tunneling between valance band and conduction band. • “Rips electrons out by their roots.”

  5. Specification for 1N754A • PTOT = 500mW • VZ = 0.8 V @ 20 mA • IZM = 55 mA • IR = 0.1A @ 25 C

  6. I-V Characteristics

  7. Typical Characteristics ID -6.8 V VD -20 mA -55 mA Keep Out!

  8. RS VO VS 1N754A RL Cathode Zener Regulator Circuit Bathtub

  9. RS VO VS 1N754A RL Cathode Zener Regulator Circuit

  10. RS VO VS 1N754A RL Cathode Zener Regulator Circuit

  11. Sloshing Water in Bathtub

  12. Two Prelabs • Review Data Sheet • Determine IZM • Select RS for zener regulator • Prelabs done before lab not first thing in lab.
