TVS - Diodes are diodes which work to protect against transient voltage surges, and their applications are extensive in the world of electronics. The BZW04-188B-E3/73 TVS Diode is a bidirectional ESD Protection and Transient Voltage Suppression (TVS) Diode, characterized in avalanche under reverse polarity conditions. The BZW04-188B-E3/73 is typically targeted at Automotive, Industrial, and Consumer applications and is an excellent choice for protecting sensitive data lines.

The BZW04-188B-E3/73 is typically used in applications such as Automotive electronics, Industrial control, or consumer electronics where ESD protection is needed. It is designed to protect against transient voltage surges and to act as a clamping device to protect sensitive circuits from damage due to ESD event. The BZW04-188B-E3/73 is capable of handling up to 20kV of ESD protection and a breakdown voltage ranging from 12V to 200V depending on configuration.

The working principle of the BZW04-188B-E3/73 is a bipolar, bidirectional diode. When a voltage surge is applied, the diode conduct in relation to its breakdown voltage. As the voltage applied by the surge is further increased, the diode begins to abruptly break down and clamp the voltage at its breakdown voltage. This allows the transient voltage to be distributed among the junction elements which in turn makes the diode responsive to extremely small transient voltage surges.

The BZW04-188B-E3/73 is capable of providing an extremely low clamping voltage at a very short rise time, which is typically defined in nanoseconds. The diode is insulated with a low outgassing and abrasion resistant material, making it suitable for use in harsh environments. It is also designed with a low capacitance that provides better EMC protection for sensitive circuits while still providing an adequate handle to 20 kV ESD protection.

The BZW04-188B-E3/73 TVS Diode is an excellent choice for protecting sensitive data lines and other circuits from ESD events. It provides ample protection at an economical cost, and is capable of handling up to 20kV of ESD with a low clamping voltage and short rise time. Additionally, its insulation material and low capacitance make it suitable for use in harsh environments, while still providing adequate protection.
