Transient Voltage Suppressors (TVS) Diodes are devices designed to protect sensitive electronic components from voltage pulses, typically in the order of several hundred volts or more, caused by electrostatic discharges (ESD) or other similar phenomena. SMDA24E3/TR7 are a versatile solution for various ESD protection of electronics applications, offering very low leakage current and high EMI suppression performance.

The SMDA24E3/TR7 is a transistor-style diode designed to protect components from electrostatic discharges. It is a low-voltage bidirectional TVS device and has and ESD rating of 25 volts. The diode has a breakdown voltage ranging from 24-25 volts and peak surge power of 125W. The diode also has reverse stand-off voltage of 9.75V, which allows it to protect circuitry from electrostatic discharges larger than 12V.

The SMDA24E3/TR7 is a small, hermetically sealed, plastic surface mount package ideal for automated soldering. It measures only 3.0 mm x 2.5 mm x 0.6 mm, making it very easy to incorporate into most any circuit. The lead pitches are designed to accept solder joints from reflow processes, ensuring high-reliability soldering. Its rugged hermetic seal also ensures reliable performance in demanding high-vibration conditions. Additionally, it has an extremely low on-state resistance.

The SMDA24E3/TR7 is designed to protect against ESD events up to 25 volts. It has incredibly low leakage current and high EMI suppression performance, making it suitable for applications where ESD pulse reduction is essential. The diode can be used with any of the three commonly used ESD protection circuitries: capacitive coupling, series resistance, and current revival circuits. For capacitive coupling circuits, the SMDA24E3/TR7 will effectively damp voltage ringing of the capacitor and ensure the circuit is protected against subsequent ESD pulses. In series resistance circuits, the diode will provide an active voltage drop of less than 1V and eliminate the effect of circuit ringing. In current revival circuits, it will provide a fast dynamic response time to clamp transients.

The SMDA24E3/TR7 is suitable for various applications where ESD protection is critical. These applications include AC/DC adapters, audio equipment, consumer electronics, gaming systems, satellite communication systems, set-top boxes, and test equipment. It is also ideal for any high-reliability application in which ESD compliance is required.

In summary, the SMDA24E3/TR7 Transient Voltage Suppressor Diode is an ideal solution for providing robust and reliable ESD protection in a variety of applications. It offers low leakage current, high EMI suppression, and small size, making it an excellent choice for portable devices and any other demanding applications where ESD protection is critical.
