SMCJ22A-TP is a TVS diode that is widely used across a variety of industries. It is specially designed for transient voltage suppression, and can safeguard sensitive electric components from transient voltage surges. The wide operating temperature range of -40 °C to +150 °C, makes it suitable for harsh environment. It is a cost effective solution for the protection of automotive, military, industrial, medical equipment.

SMCJ22A-TP is an unidirectional device. It is configured as a voltage clamp that quickly responds to transient voltage surges and eliminates them within milliseconds. It’s low power capacitance and excellent clamping characteristics provide superior performance in harsh environment. Its very fast response time allows it to protect automotive, medical and military equipment from voltage surges.

The main application of SMCJ22A-TP is to protect sensitive electronic components from transient voltage surges that may enter a circuit from a variety of sources such as lightning strikes, motor start-up, electro-static discharging, among others. Its low capacitance makes this device ideal for use in high speed interfaces such as USB3.0, SATA, HDMI, as well as low speed interfaces such as USB2.0 and Ethernet.

SMCJ22A-TP is made up of a zener diode and an avalanche diode connected in series. The zener diode is designed to protect against positive transient voltage surges while the avalanche diode is used to protect against negative transient voltage surges. The zener diode’s breakdown voltage is higher than the avalanche diode’s breakdown voltage, allowing it to absorb more energy and protect the device from a greater surge. Once the transient voltage surge exceeds the breakdown voltage of the zener diode, the current will be conducted by the avalanche diode, thus protecting the sensitive electronic component.

SMCJ22A-TP is used in a variety of industrial and consumer electronic applications. It is commonly use to protect motherboard, processor, memory chips, and other sensitive components in laptops, desktops, tablets, smartphones, and servers. It can also be used in automotive and military applications. It is an ideal choice for high speed and low speed interfaces due to its low capacitance.

The SMCJ22A-TP is ideal choice for providing protection against transient voltage surges. It’s low cost, wide temperature range, and high surge current capability make it an ideal cost effective solution for voltage surge protection in a variety of applications. It’s fast response time provides superior protection against transient voltage surges that may enter the circuit from a variety of Sources. Its low capacitance makes it suitable for high speed and low speed interfaces.
