The SMZG3803B-E3/5B Zener diode belongs to the single diode category. It is mainly used in circuits like LED regulators and LED driver applications. Its working principle is based on the Zener effect and acts as a voltage regulator. It is typically used in systems that need to maintain a constant and consistent output voltage while handling the effects of the surrounding environment and electrical parameters.

The SMZG3803B-E3/5B Zener diode is a PN junction (heterojunction) semiconductor device with a P-doped and N-doped region. When a current is allowed to flow through this diode, the PN junction acts as a rectifier and a voltage regulator. The regulation of the output voltage is based on the Zener effect, which states that when the current reaches the breakdown voltage of the PN junction, it will stabilize at that voltage regardless of any external conditions.

The SMZG3803B-E3/5B Zener diode can be used in multiple applications, including audio/visual equipment, automotive components, vacuum cleaners and many other low-voltage applications. It is designed to provide a stable output voltage and protect sensitive circuits from voltage fluctuations. It can also be used to regulate a specified voltage when voltage drops or spikes occur.

The range of output voltages provided by the SMZG3803B-E3/5B Zener diode is between 3.3V and 5.1V. The Zener voltage of this diode is typically in the range of 3 to 5 volts. It has a low forward voltage drop and low reverse voltage leakage. The diode also has a typical reverse leakage current of 2.5mA at Rz5V (reverse voltage 5V).

The SMZG3803B-E3/5B Zener diode is designed to be compatible with lead-free soldering temperatures of up to 260°C and operating temperatures between -40°C and 125°C. It also has an isolation voltage of 1500VAC RMS and a thermal resistance of 32°C/W.
