TVS – Diodes, commonly known as Transient Voltage Suppressors, are special electronic components designed to protect sensitive devices against electrical surges, overvoltages, and induced spikes. The SMBJ14CA-Q is a TVS Diode that is designed to protect sensitive electronic components against destructive voltage spikes. It is widely used in a variety of applications and has a wide variety of features that allow it to be used in high-voltage applications.

The SMBJ14CA-Q offers a low capacitance diode for ESD (electrostatic discharge) protection. It is available in various package sizes, including SOD-123FL, SC-79, SMA, and SOT-89 packages. The device is rated for a maximum working voltage of 5.0V, a peak pulse power of 600W, and a maximum stand-off voltage of 14V.

The SMBJ14CA-Q is a bidirectional device, meaning that it can protect against overvoltages in either direction (positive or negative). It also has a fast response time, meaning that it can rapidly absorb and dissipate large and/or short-duration surges, such as those caused by lightning or power supply faults. The device also features a wide operating temperature range, making it ideal for applications that may be exposed to extreme temperatures. It is also RoHS compliant and halogen-free, making it a safe and sustainable choice for applications.

The SMBJ14CA-Q uses a simple and efficient “avalanche breakdown” mechanism to protect against overvoltage spikes. The diode is designed so that when the voltage across it exceeds its maximum stand-off voltage, it quickly switches to a low impedance state. This results in a rapid reduction in voltage across the diode, which in turn ensures that the protected electronic devices do not experience any harm. This process is known as “avalanche breakdown” since it resembles an avalanche in nature.

The SMBJ14CA-Q is used in a variety of applications, including medical devices, communication equipment, consumer electronics, and automotive electronics. Its low capacitance and fast response time make it ideal for protecting high-voltage lines and sensitive components in high-speed or wireless systems. It is also used to protect wiring and equipment in industrial control systems.

Overall, the SMBJ14CA-Q is a reliable and efficient TVS Diode that is suitable for a wide variety of applications. Its low capacitance, fast response time, wide temperature range, and low cost make it an excellent choice for protecting sensitive electronic components against damaging overvoltage spikes. It is a safe and reliable device that is widely used in many applications all over the world.
