The SMBJ30CA-E3/5B is a surface-mount unidirectional Transient Voltage Suppressors (TVS) designed to protect sensitive electronics from voltage transients induced by lightning, inductive loads, or other spikes in power. It is especially suited for applications involving data communications lines.

TVS diodes are designed to protect against transient voltages events, which are often referred to as electrical overstress (EOS). They are designed to support high surge currents to short out transients, as well as allow a current in the normal direction of the circuit which exceeds the normal operating current.

The SMBJ30CA-E3/5B is designed to protect from a maximum transient energy of 14.4 Joules, and has a working voltage range of 6.0V-170V. It will protect against waveform 1 of IEC 61000-4-5 Ed 2.0, which is a typical IEC-61000-4-5 surge waveform.

The purpose of a TVS diode is to quickly reduce the voltage of incoming transient pulses that could otherwise cause damage to sensitive components. The basic operating principle of a TVS diode is that it provides a low impedance path from the TVS anode to the cathode when voltage is applied across the anode and cathode. This results in a large shift in impedance across the contacts and thereby allows for the voltage spike to be effectively dissipated or shunted. This is known as the “avalanche breakdown” effect.

In addition, the SMBJ30CA-E3/5B has a wide operating temperature range from –55°C to 150°C, making it suitable for a wide range of applications. It is constructed using a special grade of plastic designed to withstand high temperatures. This allows it to be used in harsh environments with minimal impact to its performance.

The SMBJ30CA-E3/5B is also RoHS compliant, which means it is free from lead, mercury, and other hazardous substances. This ensures that it is safe to use in a variety of sensitive applications.

The SMBJ30CA-E3/5B is suitable for use in a variety of applications, including automotive, telecommunications, industrial, and consumer electronics equipment. It is often used in power supplies, data lines, USB ports, mobile phones, and other consumer electronics. It is also suitable for use in computers, routers, and other network devices. The SMBJ30CA-E3/5B is an ideal choice for protecting sensitive electronics from transient voltage events.

The SMBJ30CA-E3/5B is a high-performance TVS diode. Its fast response time allows it to effectively protect sensitive electronics from voltage spikes and transients that they may be exposed to. Its wide operating temperature range, RoHS compliance, and low leakage current make it an ideal choice for a variety of applications. With its high surge ratings and wide working voltage range, the SMBJ30CA-E3/5B is a reliable and versatile solution for protecting sensitive electronics from voltage transients.
