TVS - Diodes

The BZW04-13 is a unidirectional TVS diode specifically designed to protect sensitive electronic equipment from voltage transients. It consists of three P-MOS avalanche diodes connected in series and sourced from a common cathode. The device is capable of absorbing repetitive ESD strikes up to the maximum level specified in JESD 22 A114 without performance degradation. It has a breakdown voltage of 13V, with an operating voltage range of 10 to 15V.

The BZW04-13 also includes many features to ensure its long-term reliability and performance. Its planar structure has been optimized to provide minimal capacitance and inductance, while its small size enables it to fit into the increasingly small electronics devices being produced today. It also utilizes power-temperature limiting technology to ensure it does not overheat, and a rupture capability which will allow it to fail safely in the event of a major surge.

The BZW04-13 is especially suited for portable electronics, IP phones, medical devices and other demanding applications. It provides a high level of last-stage surge protection in telecom and networking applications, as well as protection for the front end of a protective device. The device is also RoHS compliant.

The working principle of the BZW04-13 is based on the transit time effect. When triggered, the diode triggers a sustained avalanche breakdown, allowing positive and negative current to flow in opposite directions. This action sends harmonics and other signals through the device to the protected device. Its voltage rating also minimizes leakage current, which helps to protect sensitive components.

In summary, the BZW04-13 is a robust unidirectional TVS diode designed to protect sensitive electronic equipment from voltage transients. It is suitable for a variety of applications, including portable electronics, IP phones, medical devices and others. It utilizes power-temperature limiting and rupture protection technology to ensure its long-term reliability and performance, while its small size enables it to fit into the increasingly small electronics devices being produced today. The device is RoHS compliant and offers excellent protection for telecom and networking applications. Its working principle is based on the transit time effect, which creates an avalanche breakdown and helps protect sensitive components.
