Thyristors - SCRs

A thyristor is a type of solid-state semiconductor device that uses four layers of alternating N-type and P-type semiconductor materials. The four layers of the thyristor act to protect the semiconductor from voltage and current spikes and form a stable switching state when power is applied. They are used in consumer electronics, automotive, and industrial electronics applications, including power monitoring, voltage regulation, and in computer-controlled switching devices. The C350PB is a specialized thyristor particularly used in high power switching applications.

C350PB application field and working principle

The C350PB is a thyristor specifically designed for medium- and high-power switching applications. It is capable of switching up to 350 amps at 400 volts with a miniscule on-state voltage drop of < 0.7 volts. It also performs well in surge current applications and is immune to thermal runaway and arcing currents. Additionally, its high frequency capabilities make it well suited for AC/DC rectification and filtering applications.

The C350PB is comprised of an silicon-controlled rectifier (SCR) which acts as a bidirectional switch. When power is applied, a gate pulse connected to the control terminal activates the SCR. The control terminal triggers and reverse-bias the p-n junction, thereby allowing electrons to flow across the junction and shorting the main terminals. The main (MT) and control (CT) terminals are then connected, allowing current to flow, and the thyristor is activated. When current is applied, the SCR acts as a switch and maintains the current path until the “gate” signal is removed or current through the device is reduced.

The C350PB has incredible flexibility when it comes to power management in a variety of applications, such as AC/DC rectification, power conditioning, power factor correction, and surge protection. For example, the C350PB provides secure edge break protection during startup of inductive loads and system restarting, as well as loads that require current synchronization, static interruption, and snubber circuits. Additionally, it is resistant to short, temperature, moisture, and humidity, making it suitable for high frequency industrial applications such as DC/DC converters, UPS, frequency converters, and SMPS.

The C350PB is an ideal choice for medium- and high-power applications that require precise control and switching. Its robust design makes it resistant to voltage and current spikes and allows for precise control over current and voltage, making it suitable for even the most demanding applications. With its ability to switch huge loads with minimal voltage drop, the C350PB is an ideal choice for high-power systems.
