UDZ5V1B-7 Application Field and Working Principle

UDZ5V1B-7 is a low power Zener diode, which belongs to a wide range of Zener family. It is qualified with chip diode having a power dissipation of 500 mW and maximum repetitive peak reverse voltage of 7 volts.

UDZ5V1B-7 has wide applications in protecting circuits against electrical surges, such as flashing of capacitors, spikes, and switches. It is mostly used as a buffer for voltage-sensing circuit, transient suppression, and LED stabilization and/or dimming.

UDZ5V1B-7 operates on the basic principle of PN junction diode. This diode employs a junction, which acts as a small area on the semiconductor surface and is capable to block any current from passing in the forward direction. When a larger reverse bias voltage is applied to this junction, the depletion region width of this junction increases, allowing higher current flow, which then passes through the junction in the reverse direction. Thus, it helps in regulating steady state DC current as well as preventing large pulse current in the circuits.

UDZ5V1B-7 consists of a zener diode, which is normally biased under reverse direction and operates in forward break over region or Zener breakdown region. Therefore, when a voltage greater than the zener voltage is applied, current flows in the reverse direction, maintaining a steady forward conduction, thus providing a smooth current path in the repeative pulse mode.

UDZ5V1B-7 can be combined with other Zener diodes, transistors, and mosfets to provide robust solutions of circuit protection against electrical current surges.

In summary, UDZ5V1B-7 is a low power Zener diode with a power dissipation of 500 mW and maximum repetitive peak reverse voltage of 7 volts. It is frequently used for protecting circuits against electrical surges, like capacitor flashing, spikes, and switches. It operates on the basic principle of PN junction diode and is often combined with other Zener diodes, transistors, and mosfets for providing better circuit protection.
