TVS or transient voltage suppressors are a type of diode generally used to protect sensitive electronics from conditions such as voltage spikes, lightening, electrical ‘noise’, and momentary overvoltages. In this context, the BZW06-188RL is a a bi-directional unipolar solid-state silicon transient suppressor, based on avalanche breakdown principles. The device is ideal for the protection of electronic circuits in a variety of demanding environments, especially making itself highly useful in switching voltage regulator power supply applications and solar micro-inverter TOPswitch networks.

The principle of operation of this device is the same as that of an avalanche breakdown diode. In an avalanche breakdown diode, when a certain reverse-bias voltage (called the \'breakdown voltage\') is applied, a sufficiently large electric field is created at the junction. This large field results in the creation of electron-hole pairs which generate an exponentially increasing current. The BZW06-188RL is designed to take advantage of this phenomenon to offer electrical protection from overvoltage spikes.

The uni-directional nature of this device further implies that it only allows current in a single direction. This means it can be easily connected in series with other components. Connected in this way, when instantaneously high voltage enters the circuit, the device ‘clamps’ the voltage down to within acceptable levels, protecting the other components. The breakdown voltage and clamping voltage of the BZW06-188RL is 6v and 188v, respectively. This range makes the device ideal for a variety of applications.

The device also offers very low capacitance performance, making it ideal for applications where high switching frequency is required. In addition, it offers a typical avalanche breakdown current of 25A, and a leakage current of 10uA. This level of performance makes it an perfect choice for applications where quick and effective protection from high voltages is required.

The BZW06-188RL is an excellent example of a solid-state silicon transient suppressor, offering both uni-directional and bi-directional protection. Its low capacitance performance, high breakdown current, and very low leakage current make it a particularly effective device capable of handling a wide range of protection scenarios. As such, it is an ideal choice for any application that requires efficient electrical protection from transient overvoltage environments.
