The APT2X31S20J is a Silicon Rectifier Diode Array designed for unidirectional load current and voltage applications or AC requirements up to 400 volts. This device provides excellent ultrafast switching performance and low forward voltage drop characteristics. It is built into a flat, high voltage package style and fits into a variety of mounting arrangements.

The APT2X31S20J is a 2 phase ultrafast bipolar rectifier bridge array, with high surge capability and low forward drop, in an thermally-enhanced TO-220 package. It is specifically designed for high surge current pulses such as appplications to increase efficiency or reduce power consumption. The device is ideal for use in servers, telecom switching, and power supplies.

The APT2X31S20J’s low forward voltage drop allows for a lower power consumption than with other devices of similar ratings. Its high surge capability allows for greater flexibility in design, and the thermally-enhanced TO-220 package allows for more efficient thermal dissipation.

The APT2X31S20J is a 2-phase rectifier bridge array, with two N-channel junctions operated in inverse parallel connection. By having two of these N-channel devices, the device is able to withstand stronger surge current, with a low forward voltage drop, making it suitable for use in DC applications.

The diode array works by providing pulsed, unidirectional current flow when a forward voltage is applied. When a potential, usually with an alternating polarity, is applied, the electrons from the anode side are forced to the cathode side of the junction. This potential builds up until the threshold voltage is reached, at which point the electrons flow freely, allowing the current to enter the device.

Once the forward bias is active, and there is free flow of electrons, a negative voltage is applied to the diode array. This causes the electrons to recombine and the current to cease, causing the current/voltage cycle to repeat.

The APT2X31S20J is suitable for use in power supply and telecom systems, as well as applications in optical modulation control, DC output switching, frequency conversion, over voltage and over current protection, and bulk current conduction.

The device is considered to be particularly advantageous due to its low power consumption, high surge capability, low forward voltage drop, and wide operating temperature range. Additionally, the device is built into a TO-220 package, allowing for more reliable and efficient thermal dissipation.
