The BZD17C200P-E3-18 is a traight through type of single Zener diode, which is designed to provide a steady voltage regulation when exposed to electrical shocks, vibartion and overloading conditions. It is a 2W Zener diode with a maximum power dissipation of 200 milliwatts and a breakdown voltage of 18 volts.

Applications of the BZD17C200P-E3-18 range from EMI/RFI suppression and overvoltage protection, to voltage reference and signal clamping. It is also suitable for signal isolation and signal switching applications, as well as for use as a voltage regulator in low power devices, like LED lights and sensors.

The working principle of the BZD17C200P-E3-18 is based on the Zener effect, which occurs in semi-conducting materials when voltage is applied across them. When a positive voltage is applied to the diode, the current will flow until it reaches the breakdown voltage of 18 volts, at which point the current will remain constant regardless of the voltage applied. As a result, the BZD17C200P-E3-18 will maintain a steady output voltage of 18 volts when supplied with a higher voltage.

The Zener diode exhibits an avalanche effect, which is another form of voltage regulation. When the Zener diode experiences an overvoltage, the avalanche effect causes a surge of current which is limited to a relatively safe level by the device\'s maximum power dissipation rating. This has the effect of providing a degree of overvoltage protection, allowing the BZD17C200P-E3-18 to be used in environments where there is a possibility of voltage spikes or surges.

The BZD17C200P-E3-18 is designed to operate between -55°C and +150°C, meaning it is suitable for most applications, including those in extreme temperature environments, such as automotive, industrial, and aerospace. It has a maximum reverse leakage current of 1.7mA and a maximum surge current of 20mA.

In conclusion, the BZD17C200P-E3-18 is a versatile and reliable single Zener diode with a breakdown voltage of 18 volts. It is suitable for a wide range of applications, from EMI/RFI suppression and overvoltage protection, to voltage reference and signal clamping. It is also capable of operating in extreme temperature environments, thanks to its wide temperature range of operation.
