PD421007

Thyristors - SCRs - Modules

A PD421007 is a Silicon Controlled Rectifier (SCR) application field and working principle module, also known as a Thyristor. A Thyristor is a semi-conductor device that is used to control the flow of electric current. It can function as both an electronically controlled switch and a voltage regulator. The PD421007 is made up of four terminals: an anode (A, +), a cathode (K, -), a gate (G) and a control unit (CU).

The gate terminal is used to control the current flow. By applying a positive voltage to the gate, the SCR will conduct a current from its anode to its cathode. Applying a negative voltage to the gate will switch the current off. The voltage requirement for the gate detection is typically less than 3 Volts and the device Draws a very small current.

The control unit (CU) is used to control the switching of the SCR. The CU is designed to provide an external control to the SCR with signals from a logic circuit which is available from the module’s terminal. This allows the user to control when and how the module is to be activated, and gives flexibility in the application.

The PD421007 comes in an industry-standard package with an internal Zener diode that provides protection against damaging transients. This helps increase the reliability of the SCR and makes it more resistant to thermal and other electrical stresses. The module also features a low forward voltage drop and a low gate voltage.

The PD421007 offers users a number of advantages in their applications. The low operating and gate voltages, the compact physical size and the ability to provide external control make this module suitable for a wide range of applications, such as power control, switching, motor control, and UPS systems.

The PD421007 is a powerful and reliable module suitable for a variety of applications. The extremely low operating voltage and the four-terminal design make it a great choice for many applications. The external control options and the protection against surges makes this module a great choice for most applications.
