Introduction

TD285N12KOFHPSA2 is a type of thyristor modules. It belongs to the family of Silicon Controlled Rectifiers (SCRs) or thyristors. It is a type of power semiconductor device that is used for industrial and consumer applications. This module can block direct current and control alternating current with a signal or control signal.

Application Field of TD285N12KOFHPSA2

TD285N12KOFHPSA2 is suitable for light switching, phase control, motor speed control, soft starting and current limiting in induction heating, energy-saving lamps, motor control, charger control and variable frequency drives applications. It is particularly suited for pole-changing control, positive voltage raise and decreasing control and AC power triggering in light dimmer, heater and welding tools.

It is also suitable for soft start, power-factor correction, energy saving mechanisms and electric inductive heater applications. TD285N12KOFHPSA2 is used in high-voltage, medium-power applications such as high-voltage lamps, street lamps, high-voltage motors, UPS systems, photovoltaic inverters and welders.

Working Principle of TD285N12KOFHPSA2

The working principle of TD285N12KOFHPSA2 is based on a thyristor, which is a three-terminal semiconductor device that works as a switch. A thyristor consists of four layers of semiconductor material with one layer of p-type semiconductor sandwiched between two layers of n-type semiconductor, separated by a junction. The gate voltage can be applied to the gate terminal to control the operation of the thyristor and to turn on or off the circuit.

When the gate voltage is greater than a certain threshold voltage, the thyristor is turned on and it begins to conduct current. The thyristor remains in the conducting state until the anode current decreases to zero. At this point, the anode voltage rises and the thyristor is switched off again. The operating principle of TD285N12KOFHPSA2 is similar to that of other types of thyristors.

In general, TD285N12KOFHPSA2 is designed to operate efficiently and safely in the minimum circuit pressure drop and maximum current ratings of a single transistor. The integrated closed loop protection system helps to provide a reliable switch and extra protection features such as short- circuit protection, over-voltage protection, over-temperature protection, over-current protection, and more. The module is designed to deliver excellent switching performance and stable operation.
