P3403ABL60

Thyristors are semiconductor devices used to regulate current and voltage, and the P3403ABL60 is a specific type of thyristor. It is used in high temperature applications such as switching on or off high power circuits and controlling power surge protection. It has a low on-state voltage drop and high blocking voltage.

The P3403ABL60 is a 6 Amp, 600 Volt, 3-Pin thyristor with a voltage regulating pulse width modulated (PWM) control system. It is designed to provide over-voltage and over-current protection against power surge and overload. It can be used for systems requiring quick power cutoff especially those powered by AC mains.

The P3403ABL60 is ideal for applications that require high current delivery, such as welding machines, HVAC systems and electric motors. It has an over-current rating of 6A at 150°C junction temperature, a reverse blocking voltage of 600V at 25°C and a triggering gate current of 10mA at VT. Its response time is typically 10μs.

The principle of operation is simple. When the VS input is positive and the gate input is four volts below the anode, the thyristor will be turned on. The voltage at the gate will not exceed four volts above the anode. Conversely, when the gate voltage is reduced to one volt below the anode, the thyristor will turn off, allowing no current to flow through it. During operation, the P3403ABL60 ensures that the load circuit is protected from over-current and over-voltage by regulating the pulse width. If the load circuit requires a higher current, the voltage is increased to compensate, and if the load requires a lower current, the voltage is decreased.

The P3403ABL60 is also available in a dual package containing two thyristors with two gates and two cathode pins. This helps to reduce the board footprint and minimize power loss due to the higher currents and voltage. In addition, it features a variety of packages which can accommodate a wide range of printed circuit board designs.

The P3403ABL60 is a perfect solution for applications requiring compact, reliable, and efficient thyristors. It offers superior protection against over-voltage and over-current conditions. It is a versatile device that can be used in a variety of industrial and consumer electronic applications.
