• Introduction:
  The SMBJ130 is a single bidirectional transient voltage suppressor diode, designed for use in protecting circuits from transients caused by ESD, power surge and other electrostatic discharges. Its low capacitance and fast response time make it suitable for a variety of applications, ranging from consumer electronics to automotive and aerospace applications. It is often used for transient voltage protection from EMI/RFI sources, as well as power supply and DC/DC converter protection.
• Features:
  The SMBJ130 offers a wide range of features that make it an ideal choice for TVS protection. It has a low clamping voltage and fast response time, making it suitable for a variety of transient voltage surge protection applications. Its epoxy resin coating also helps protect it from environmental damage, such as humidity and moisture. In addition, it is RoHS compliant and can withstand temperatures up to 150°C. With a peak power of 500W, it is also highly reliable and durable.
• Applications:
  The main application of the SMBJ130 is surge protection for power supplies and circuits. It can be used in consumer electronics, automotive and aerospace applications, such as protection from EMI/RFI and power supply failures. Other applications include protection from power leakage and shorts in DC-DC converters, as well as supplying an additional layer of protection for sensitive components in circuits.
• Working principle:
  The SMBJ130 is a diode that acts as a bridge between primary and secondary circuit paths. When a voltage surge occurs, the diode begins to conduct, increasing the current from the source and allowing it to flow through the diode. The current then passes through the diode where it is divided between the two paths. The surge is absorbed by the diode and dissipated as heat.
• Conclusion:
  The SMBJ130 is a highly reliable and durable diode designed for transient voltage surge protection. It offers low capacitance, fast response time and an epoxy resin coating for protection from environmental damage. Its wide range of features makes it an ideal choice for TVS applications, including consumer electronics, automotive and aerospace sectors.
