TVS - Diodes

Transient Voltage Suppression Diodes (TVS-Diodes) are components used to protect sensitive circuit elements from electrical spikes and surges. The BZW04-154HE3/54 is a popular TVS Diode in the industry, widely used to protect circuits from voltage overshoots – both transients and ESD(Electro Static Discharge).

Application Field and Working Principle

The BZW04-154HE3/54 TVS Diode is widely used in a variety of applications ranging from automotive to consumer electronics. It is commonly used to protect circuits from ESD and other voltage transients. This device is designed to protect the sensitive input stages of the circuits against the damaging voltage from static discharge strikes and lightning. It has a low capacitance which makes it suitable for high-speed communication protection.

The BZW04-154HE3/54 TVS Diode works by absorbing large amounts of electrical energy and dissipating it into a non-conducting state. This is done by zener breakdown of the junction and by avalanche breakdown of the device, resulting in a rapid breakdown voltage that are much higher than the normal bias voltage of the diode. This allows the diode to be able to safely absorb electrical overshoots and spikes up to the rated breakdown voltage.

Once the breakdown voltage is exceeded, the TVS Diode will conduct current and is capable of dissipating large amounts of power, making it an ideal choice for protecting sensitive circuit components. The device is also designed to provide protection against reverse biasing which is typically used to ensure that protection against reverse discharge is provided.

The device is designed to dissipate large amounts of power efficiently and with minimal thermal losses, making it suitable for use in industrial and consumer applications. The device also features a low capacitance, which makes it suitable for high-speed communication protection.

The BZW04-154HE3/54 TVS Diode is a popular choice for many applications and is an excellent choice for both general-purpose and high-speed protection.
