TVS - Mixed Technology

The BSPD120600D3K is a unidirectional Transient Voltage Suppressor (TVS) device. This device falls into the “mixed technology” category of TVS devices because it combines silicon technology with the capability of overvoltage protection with integrated protection diode. This device is available in 1206 surface mount package and is rated for up to 600W peak pulse power.

Application Field

The BSPD120600D3K TVS is suitable for use in a wide range of electronic circuits. It is commonly used in automotive, telecommunications, networks, and industrial applications where voltage transients must be controlled. It can protect against both normal and overvoltage conditions. Its common application field includes:

• Power Supply Overvoltage Protection
• Signal Lines Protection
• Data Lines Protection
• Inductive Loads Protection
• Transient Voltage Surge Suppressor

Working Principle

The BSPD120600D3K is a bidirectional TVS device, meaning that it can protect from both positive and negative transient voltage spikes. It works by suppressing high energy pulses and quickly limiting excess voltages. This is achieved through its series silicon technology combined with the fast response speed of its protection diode. It can absorb large amounts of power and its silicon technology also allows it to reset quickly and continue to provide protection.

In normal operation, the BSPD120600D3K TVS works by allowing a current to flow through it in the forward direction. When a transient voltage spike occurs, it causes the current to exceed its maximum forward current capacity. This causes the device to enter the active clamp state, which causes the device to start to absorb the excess energy from the spike. It then releases this energy in a shorter pulse and limits the voltage across the device. This helps protect the circuit and its components from the potentially damaging effects of transient overvoltage.

The BSPD120600D3K is designed to offer a low clamping voltage and fast response time, allowing it to protect circuits from the damaging effects of transient overvoltages. Its compact size and surface mount package make it suitable for use in a wide range of electronic circuitry.
