TVS devices, commonly known as Transient Voltage Suppressors (TVS), protect electronic components from electrostatic discharge (ESD) or lightning strike surge voltages. The P4SMA170CAHE3/61 is a unidirectional transient voltage suppressor (TVS) diode specifically designed for the protection of signal line applications. It is the perfect controller for highly sensitive and mission critical applications in consumer, industrial, and automotive markets.

This robust TVS diode has many features that make it an ideal choice for application protection. It is made with an energy absorption rate of up to 20 amps and an ESD protection level of up to 8kV, making it suitable for high-rate ESD protection applications. It offers low breakdown voltage of 4.4V, excellent transient on-state current performance, and excellent temperature coefficient. It also features low leakage current, low capacitance, low inductance, low jitter, and EMI shielding capabilities. This device is available in a RoHS-compliant SMBJ110A package, designed for low-profile, small size, and 100% isolation from the printed circuit board (PCB).

The P4SMA170CAHE3/61 is an excellent device for protecting sensitive electronic components from ESD and lightning strikes. It is a great choice for portable devices such as mobile phones, tablets, GPS units, and other handheld devices that require both ESD and lightning protection. Its low leakage current, low capacitance, and low inductance make it an ideal choice for ground loop noise mitigation in long transmission lines.

The working principle of the P4SMA170CAHE3/61 is relatively simple. It is a single unidirectional device divided into two parts – anode and cathode. When a voltage greater than the breakdown voltage is applied between the anode and the cathode, the TVS diode conducts, clamping the voltage at the breakdown voltage and limiting the current. This ensures sensitive components are protected from transients and ESD pulses. When the voltage drops below the breakdown voltage, the diode reverts to its off state, where the voltage is held at a safe level.

In summary,the P4SMA170CAHE3/61 is the perfect choice for applications requiring robust protection against ESD and lightning strikes. Its low breakdown voltage, high energy absorption rate, and EMI shielding capabilities make it an ideal controller for highly sensitive and mission critical applications in consumer, industrial, and automotive markets. Moreover, its low leakage current, low capacitance, and low inductance make it the perfect device for ground loop noise mitigation in long transmission lines.
