The SMBJ220AE3/TR13 TVS diode, also simply referred to as a Transient Voltage-Suppressor (TVS) diode, is a device used to protect circuits against the destructive effects of electrostatic discharges (ESDs). It is a fast-acting voltage or current limiting device designed to shunt high-current discharges to ground and thus protect sensitive equipment from malfunction or destruction.

This device is a surface-mount discrete semiconductor that is designed to protect against lightning and other transient voltage pulses. It is a double diode with symmetrical devices connected in parallel. It has three leads, consisting of two terminals (anode and cathode) and a case lead for dissipating heat. The SMBJ220AE3/TR13 has a breakdown voltage of 220 V and a leakage current of 150 μA. It also has a low capacitance of 15 pF and a low reverse-standoff voltage of 160 V.

The SMBJ220AE3/TR13 is well-suited for use in higher-voltage applications, such as telecom and datacom equipment. It is most commonly used as an intermediate protection element for communication lines, power supply lines, or data lines in a variety of applications, including computers and peripherals, mobile phones, and consumer electronics. It is also widely used in automotive electronics, AV receivers, power supplies, and industrial controllers.

The major application fields of SMBJ220AE3/TR13 include data and telecom equipment, mobile phones and consumer electronics, automotive electronics, AV receivers, power supplies, and industrial controllers. This device has been designed in accordance with UL1449 rating of 600 W (10/1000 us waveform). This ensures reliable operation of the device for applications involving high-energy induced transient overvoltages.

The working principle of the SMBJ220AE3/TR13 is to conduct a surge current to ground whenever a transient voltage surge greater than or equal to the breakdown voltage of 220 V is detected. When the surge is over, the device automatically turns itself off and returns to its original state, allowing normal circuit operation to continue. This means that it has a high protective capability even in the face of large and repeated surges, making it reliable and highly reliable in protecting sensitive circuitry.

To maximize protection, engineers should select a TVS diode with a breakdown voltage that exceeds the expected peak voltage of the transient. Obviously, it is also important to choose a device with a leakage current that is low enough to allow for a safe recovery period after the Surge has occurred. SMBJ220AE3/TR13 is an ideal choice for high voltage applications due to its high breakdown voltage, low leakage current, low capacitance, and low reverse-standoff voltage.

In summary, the SMBJ220AE3/TR13 TVS diode is a reliable and efficient protection device. Its major application field includes telecom and datacom equipment, mobile phones and consumer electronics, automotive electronics, AV receivers, power supplies, and industrial controllers. Its fast response time and low leakage current makes it ideal for protecting circuits against ESDs, lightning, and other transient voltage surges. Its low capacitance, low reverse-standoff voltage and high breakdown voltage further make it an ideal choice for high-voltage applications.
