TDK4403002DH

Thyristors - SCRs, or Silicon Controlled Rectifiers, are electrical components mainly used in electronic circuits for controlling power, providing heavy-duty switching capabilities with their enhanced efficiency and durability. The TDK4403002DH is avery popular SCR from TDK, consisting of a four-quadrant gate with a maximum gate current of 1.5A and a maximum surge current of 8A. It is capable of handling a maximum forward continuous operating current of 5A and a maximum reverse continuous operatingcurrent of 0.5A. It operates at a maximum forward voltage of 400V and maximum reverse breakdown voltage of 400V. The TDK4403002DH is used in a variety of applications, such as switching, motor control, and voltage regulation.

The working principle behind SCRs, and the TDK4403002DH specifically, is that when the device is connected to a DC or AC voltage source, the SCR will conduct in one direction only, allowing current to flow between two terminals depending on the polarity of thevoltage source. The TDK4403002DH must be turned on, or triggered, with a small gate current in order to start its conducting state. The TDK4403002DH is triggered with a current between 1mA and 1.5A, and its current will remain in its conductingstate until the voltage drops below a certain threshold. This threshold is called the “off-state gate current” and is approximately 1mA for the TDK4403002DH.

The TDK4403002DH is used in a wide range of applications, from light-load to heavy-load applications. In low-power applications, the TDK4403002DH is used for switching devices such as electric water heaters, electric ovens, light dimmer switches, andtime-delay relays. In high-power applications, it is commonly used in motor control devices such as electric motor starters, electrical induction motors, and motor brake controllers. It can also be used in voltage regulation devices, such as voltage-regulatedDC-DC converters. It is also used in AC regulators, AC servo systems, and AC uninterruptible power supplies.

The TDK4403002DH is a very popular SCR due to its high efficiency, reliable operation, and ease of use. It is capable of handling a wide range of current and voltage levels, and its durability makes it suitable for use in a variety of applications. With itsversatility and reliability, the TDK4403002DH is a great choice for any project that requires an efficient and powerful SCR.
