SZBZX84B24LT1G – Application Field and Working Principle

SZBZX84B24LT1G is a diode from the Zener Single family, a type of diode that is designed to operate in reverse-bias (or breakdown) mode. It is ideal for voltage regulation, waveform clipping, and surge protection applications. In this article, we will take a detailed look at the SZBZX84B24LT1G’s application field and working principle.

Application Field

SZBZX84B24LT1G is generally used in the applications below:

• Voltage stabilization and regulation circuit: when used as a voltage regulator, the SZBZX84B24LT1G diode can provide a relatively stable output voltage despite changes in the input voltage or current. This is because the diode automatically adjust its forward voltage drop to prevent the output voltage from exceeding the rated zener voltage. In substitution of an Ohmic element, the SZBZX84B24LT1G diode can protect circuits from reverse-bias voltages and high-speed transient voltages.
• Surge protection circuit: a Zener diode is preferred in surge protection circuits for its performance in suppressing high transient voltages caused by electrostatic discharge, lightning-induced surges, or other overloads. The breakdown voltage of the Zener diode can be adjusted by properly selecting the right Zener characteristic.
• Waveform Clipping Circuit: SZBZX84B24LT1G can be used to clip (limit) the amplitude of sinusoidal, rectangular, triangular, and other waveforms. This type of application allows the diode to alternately operate in forward and reverse bias to limit the peak voltages below the desired levels.

Working Principle

The SZBZX84B24LT1G is a Zener Single, which means it operates in the zener breakdown region when connected in opposite bias. When the diode is in the forward bias, it simply acts as a forward biased diode, allowing current to flow in the external load, turning it on. However, when the reverse voltage exceeds a certain level, the p-n junction breaks down, allowing a low voltage and current to pass across it. The breakdown voltage is relatively stable and defined by the diode’s characteristics, also known as the Zener voltage.

When a voltage spike or surge occurs, the diode will immediately enter the breakdown region and start to conduct power from the load, thus dissipating all excess energy from the surge. This is why Zener Single diodes are used in all kinds of protection circuits for voltage stabilization, voltage clipping, and surge protection.
