1SMA200ZHR3G

The 1SMA200ZHR3G diode, often referred to as the Zener diode, is a type of single diode that can be used in a variety of applications and is unique in its ability to allow current to flow in one direction, while blocking reverse current. This makes the 1SMA200ZHR3G ideal for overvoltage protection and voltage regulation, in addition to other applications.

Application Field

The primary application for the 1SMA200ZHR3G is overvoltage protection, as the diode is designed to limit a voltage to a specific level. When an input voltage exceeds the Zener voltage, the diode begins to conduct current, limiting the other device to a safer level and protecting it from damage. The 1SMA200ZHR3G is also used for voltage regulation, as the Zener voltage is controlled by varying the amount of reverse biased current passing through the diode. Additionally, the 1SMA200ZHR3G is used for frequency clamping, noise suppression, and waveform shaping and is often used in inverters, converters, and op-amps.

Working Principle

The 1SMA200ZHR3G is a single diode with a Zener breakdown voltage which, when exceeded, allows current to flow from the anode to the cathode. When the reverse biased voltage applied to the 1SMA200ZHR3G is less than the Zener voltage, the diode appears to be an open circuit, blocking all current flow. However, when the reverse bias exceeds the Zener voltage, the diode will turn on and start to conduct current, while still limiting the voltage to the Zener voltage as long as the bias is maintained. This makes the 1SMA200ZHR3G ideal for applications where one or more devices must be limited to a specific voltage.
