TVS (transient voltage suppression) diodes are designed to protect sensitive electronic components and circuits from transient voltage surge events. The SMBJ200A-TP is a unidirectional, low-capacitance, high-speed transient voltage suppressor diode, designed for circuit protection applications. It is available in a SOD-123 package and is rated for 200 Watts peak power dissipation (1.0/1000μs).

The device meets IEC 61000-4-2 (ESD) ± 15kV (air/contact discharge) and comes with an integrated protection network of materials and structures such as nano-grade Pb10, carbon impregnated, and airgap layers. This integrated circuit protection network ensures that transient voltage surges are absorbed quickly and safely before they can cause any harm to sensitive circuitry and components. Additionally, the device offers excellent clamping capabilities, making it the ideal choice for use in transient voltage suppression applications.

The SMBJ200A-TP is suitable for various applications such as automotive systems, computers, telecommunications, consumer electronics, and other industries that require transient voltage protection. Its low capacitance design ensures that the device will not interfere with the normal operation of sensitive circuits. The device is also designed with internal thermal disconnect, which prevents it from overheating during extended high power transient surge events.

The working principle behind the SMBJ200A-TP diode is simple. It is activated when the transient voltage exceeds its breakdown voltage. At this point, the diode begins to conduct, allowing a controlled amount of current to the circuit for protection. As the surge passes, the diode then returns to its normal blocking state. This process works to protect the sensitive circuits and components by limiting the peak transient voltage.

To ensure proper operation, the device must be adequately sized for its intended application and the total number of devices used must not exceed the recommended maximum. Additionally, the SMBJ200A-TP should be installed in series between the source of power and the sensitive circuitry to be protected. Finally, proper grounding is essential to the proper functioning of the device, so proper grounding measures should be taken to ensure safety.

The SMBJ200A-TP is a robust and reliable transformer voltage suppressor diode, designed to protect sensitive electronics and circuits from transient voltage surge events. With its integrated protection network and exceptional clamping capabilities, the device is the perfect choice for transient voltage protection applications. Its low-capacitance design ensures that it will not interfere with the normal operation of sensitive circuits, while its internal thermal disconnect helps to prevent overheating during extended high power transient surge events. Proper installation and grounding are essential for the device to function correctly, and the device should be correctly sized for its intended application and the total number of devices used should not exceed the maximum recommended.
