TVS - diodes, also known as transient voltage suppressors, protect power and communication circuits from voltage transients created by lightning, electrostatic discharch (ESD), load switching, and other sources that cause an electrical disturbance at the input. SMBJ100CA-TR are components designed to protect sensitive electronic components from such voltage transients.

SMBJ100CA-TR are unidirectional transil diode arrays. They comprise of two back-to-back avalanche breakdown diodes, connected in series in an epoxy package. This combination helps the circuit from transients having higher than normal voltage. The SMBJ100CA-TR has a peak surge power rating of 500 watts and a stand-off voltage of 100V. It is designed to protect sensitive electronic components from a wide range of transients.

The SMBJ100CA-TR has an incredibly fast switching speed, allowing it to respond quickly to voltage transients. It’s a surface-mount component that has very low resistance, and its epoxy package helps protect it from vibrations and other external elements. It also has a maximum clamping voltage of 140V, meaning it will protect the circuit from any voltage transients above that value.

The SMBJ100CA-TR is an ideal choice for semiconductor protection due to its low junction capacitance and surge capacity. Its fast switching speed helps protect high-speed data lines from voltage transients and ESD, and its epoxy package helps protect against moisture and dust. It is also widely used in automotive and military applications for protecting circuits from high voltages and surges.

The working principle of the SMBJ100CA-TR is based on the avalanche breakdown of a silicon diode. When voltage across the diode becomes greater than its breakdown voltage, the diode will start conducting current and clamp the transient voltage. The epoxy package helps dissipate the heat generated by the avalanche effect and also prevents the diode from sustaining further damage due to the transient.

The SMBJ100CA-TR is an invaluable tool for protecting sensitive circuitry against transients. It is used in a wide range of applications, including computers, consumer electronics, telecom systems, automotive, and military applications. Due to its robust design and fast switching speed, it is a reliable choice for protecting against voltage transients.
