The TVS-Diode, or Transient Voltage Suppression Diode, is a diode designed to protect vulnerable electronic components from unpleasant voltage transients or surges. 3KP180C is a leading edge product in this field. This article will present 3KP180C’s application field and working principle.

3KP180C is designed for industrial and consumer electronic systems including AC power lines, data and telecommunications lines. This product offers fast response time and high-temperature stability for applications requiring high reliability and repetitive pulse protection. As a typical unidirectional TVS, it can clamp transient voltages to a safe level. It is designed for I/O interface protection and AC power line protection. It is a lead type diode compatible with automated production processes and offers replaceable protector components.

The working principle of the 3KP180C is simple. When a transient voltage greater than the specified clamping level is applied, the diode will let current surges through its junction, thereby limiting the voltage across the vulnerable component, thus providing effective protection. The diode clamping voltage can be expressed as: V _CLAMP =V_BR +I_PK x R _CLAMP , where V_BR is the breakdown voltage, I_PK is the peak surge current and R_CLAMP is the clamping factor. The diode has a high repetition rate capability, for instance, the 3KP180C with 5 amps peak pulse current can operate at a repetition rate of 1000pps.

In addition to the fast response time and high temperature stability, one of the key features of the 3KP180C is its low clamping voltage. With a breakdown voltage of less than 13 volts and a low clamping voltage of only 24.5 volts, this product is well suited for low voltage AC power line and data line protection and I/O interface protection. The diode also has a low capacitance that makes it an ideal choice for applications requiring fast transient protection response.

The 3KP180C’s unique design provides superior protection for any vulnerable component. Its low clamping voltage, fast response and high temperature stability make it an ideal choice for industrial and consumer electronic system applications such as AC power lines, data and telecommunications lines. It is also a cost effective and reliable solution for protecting vulnerable components from unpleasant voltage spikes or surges.
