Thyristors - TRIACs are semiconductor devices that are typically used to control power and current flow in electrical circuits. The QJ4016RH4TP is a four terminal thyristor that is used for bidirectional AC power control in a variety of applications. This article will discuss the application field and working principle of the QJ4016RH4TP.

Applications of the QJ4016RH4TP

The QJ4016RH4TP is a four terminal thyristor with a 200A/400A current rating and a 600V-800V voltage rating. It is designed specifically for AC power control. Typical applications of the QJ4016RH4TP include light dimmers, motor controllers, motor speed controllers and motor starters. The thyristor can also be used for phase control of AC induction motors and for rectifier control in high power AC to DC power supplies.

The QJ4016RH4TP device is a three chip package, which contains four terminals. The first two pins, labeled "G" and "MT" are gate and main terminal, respectively. The second pair of pins, labeled "B" and "C" are the opposite terminals. It features high turn-off and soft turn-on capability, extended temperature range, and a wide choice of gate triggering circuits. The device also features built-in over-voltage protection, current surge and short circuit protection, and overload protection.

Working Principle of the QJ4016RH4TP

The QJ4016RH4TP is a gate-controlled bidirectional AC power switch. The device can switch currents and voltages in both directions and in any given combination. The thyristor is triggered through the "gate" pin. The thyristor will stay in the "on" state until the current ceases to flow through the "MT" pin. At this point, the device will switch to the "off" state, thus preventing any further current flow. The device must be reapplied each time in order to turn "on".
