The TISP4082F3LMR is an unidirectional enhance mode bidirectional Transient Voltage Suppressor (TVS) diode manufactured mainly for surface mount applications (such as consumer electronics, computers, communications and automotive).

TVS devices are designed to protect electronics circuits from transient voltage produced by Electro-Static Discharge (ESD), as well as lightning-induced abnormal voltages and Electromagnetic Interference (EMI). It also serves as a superior protection device during times of electrical power surges. TVS devices work by acting like small signal diodes when the voltage in a circuit is within safe limits, and increase the voltage breakdown of the unit when the voltage exceeds the threshold, thus providing a high degree of protection.

The TISP4082F3LMR is a silicon-based, approximately 2 mm x 3 mm Ambient Light Sensitive (ALS) TVS diode, with a working range of -12.2 V to +15.7 V. It has a low breakdown voltage of 18 Volts, and has a peak pulse power of 2400 Watts. The operating temperature ranges between -50°C to + 105°C. Its current rating is 3.0 Amps with a capacitance between pins of 5.6 pF.

The TISP4082F3LMR provides a well-defined electrical characteristic and is designed to protect systems from transient over-voltage events such as Electro-Static Discharge (ESD) or lightning-induced surges, as well as Electro-Magnetic Interference (EMI). It is also used in consumer electronics, computers, automotive and communications, where an ambient light sensitive line of devices, due to its highly precise electrical characteristic, is a superior protection device.

The TISP4082F3LMR can be used to protect a wide variety of electronics from transient over-voltage events. Its small form factor allows it to be used in tight places where it provides protection from ESD, EMI, and power surges. Due to its low capacitance, the device provides good noise immunity. Moreover, the device is designed to trigger on the rise or fall of a transient voltage spike and provide protection to adjacent circuits, regardless of its peak amplitude or wave shape.

The working principle of the TISP4082F3LMR is that it protects the circuit from transient over-voltages by clamping the voltage at a predetermined level. During normal operation, the device works as an ordinary diode and has no influence on the normal operation of the circuit. However, when the voltage exceeds the device’s breakdown voltage, the device is triggered and it begins to clamp the voltage through a highly conductive, low-resistance path.

In conclusion, the TISP4082F3LMR is a highly reliable and effective device making it an ideal choice for protecting a wide range of electronic circuits from damage caused by transient over-voltage events. Its small form factor, low capacitance and excellent electrical characteristics make it ideal for use in a variety of consumer electronics, computers, communications and automotive applications, providing superior protection against ESD, EMI and electrical power surges.
