B120AE-13

A diode is a semiconductor device that allows current to flow in one direction but not the other, usually used as a rectifier or switch. The single B120AE-13 diode is a high-power, low-drop rectifier diode specifically designed for applications that need to handle large currents. It is a useful tool for designers who demand low forward voltage drop, low effective capacitance, and superior RF noise suppression.

The B120AE-13 is a 1,200-volt, 3-amp diode made with Advanced Heterojunction technology. This high-speed switching diode offers 300 mV of forward voltage drop when passing a current of 3A and above, making it especially useful in power switching applications. This device also offers superior thermal performance with a maximum operating junction temperature of 175°C.

The B120AE-13 diode is available in both SOD-123 and 2-lead TO-220 packages, allowing it to be used in a variety of applications. Those applications include server and notebook power supply, battery charger, and low-cost offline power supplies. This diode has a reverse recovery time of 10 ns, which is one of the shortest among 1,000V class diodes, ensuring smooth current switching for excellent EMC characteristics.

The working principle of the B120AE-13 diode involves the transfer of electrical current between P and N materials when the forward voltage is applied across it. This voltage-current transfer results in the passing of electrons from the P side to the N side of the diode, allowing current to flow through the diode in one direction. The diode also acts as a rectifier, which prevents current from passing through the diode in the reverse direction.

In summary, the B120AE-13 diode is a high-power rectifier diode specifically designed for applications requiring high currents, low forward voltage drops, low effective capacitance, and superior RF noise suppression. It is available in SOD-123 and 2-lead TO-220 packages, and offers excellent thermal performance with a maximum operating junction temperature of 175°C. It is an ideal choice for power switching applications, server and notebook power supply, battery charger, and low-cost offline power supplies.
