TVS - Diodes help to protect circuits from high energy transients such as electrostatic discharge (ESD), lightning, etc. They are an essential component of any circuit design to ensure the desired performance of the circuit. The BZW50-39BRL is a type of transient voltage suppressor (TVS) diode. It is designed to protect circuits against voltages that exceed specific limits. In this article, we will discuss the application field and working principle of the BZW50-39BRL.

The BZW50-39BRL is an axial leaded protective diode. It has an operating voltage range of 6V to 39V, allowing it to protect circuits from voltages that exceed this range. The device features a low reverse leakage current of 25µA, allowing for increased protection in sensitive applications. What makes the BZW50-39BRL unique is its ability to protect both high and low voltage transients. This feature makes it ideal for use in automotive, consumer electronics, medical, industrial, and military applications.

The working principle of the BZW50-39BRL is relatively simple. When a transient voltage is applied to the diode, it begins to conduct. The diode acts as a clamp, limiting the voltage across the device to a safe level. The transient energy is then dissipated as heat. This is known as the avalanche effect, which is triggered by a sudden change in voltage. The diode will clamp the voltage until the transient has dissipated, thus protecting the underlying circuits.

In addition, the BZW50-39BRL is available in a wide variety of packages to meet different design requirements. The device is offered in a variety of dimensions, including the TO-220, SMA, and SMB packages. There are also RoHS compliant and tin-lead plated versions available. All these packages offer increased thermal performance and reliability.

Overall, the BZW50-39BRL is an ideal protective diode for applications requiring high and low voltage protection. With its low leakage current and variety of available packages, the device can be easily integrated into any circuit design. Due to its robust design and reliable performance, the BZW50-39BRL makes an excellent choice for high voltage protection in automotive, consumer electronics, medical, industrial, and military applications.
