Diodes - Rectifiers - Single

SD103BWS-E3-18 is a single diodes rectifier that belongs to the SD103BWS series. It was designed and manufactured by NXP Semiconductors and is suitable for use in many applications such as equipment and computer power supplies, telecommunications systems, automotive equipment, converters and power circuits.

The SD103BWS-E3-18 consist of a 1.0 Amp 50 Volt rectifier diode with a fast switching speed. The device has a VF (forward voltage drop) of 1.2 volts at 0.6A, and a reverse recovery time of 130ns.

The device has a maximum continuous current rating of 1.0 Amp and a maximum PRV (Repetitive Peak Reverse Voltage) of 18 volts. It is designed to withstand a maximum allowable forward current of 5.0 Amps, with a forward surge current of up to 10 Amps for 10ms.

The device has an encapsulation of a molded plastic 6-pin DO-218AA package with a base of Pure oxygen-free copper, and a thickness of 1.1mm. It requires a minimum lead temperature of 250 °C during soldering process. The device is RoHS compliant.

The working principle of the SD103BWS-E3-18 is based on its ability to act as a two-terminal regulator or active current source in a circuit. It works by allowing current to flow in one direction (forward) and blocking current in the other direction (reverse) such that the circuit is regulated.

When a forward bias is applied to the diode, electrons from the cathode are able to flow freely through the diode due to the reduction of the barrier voltage of the anode, which shortens the total resistance of the circuit. This, in turn allows current to flow through the diode from anode to cathode.

When a reverse bias is applied to the diode, the charge carriers are blocked due to the increased barrier voltage at the anode and therefore, current cannot flow in the reverse direction. This will prevent voltage spikes and uncontrolled current in the circuit.

In summary, the SD103BWS-E3-18 is a single diodes rectifier that is suitable for many applications. The device has a maximum continuous current rating of 1.0 Amp, a maximum PRV of 18 volts and a forward surge current of 10 Amps. The device works on the principle of allowing current to flow in one direction and blocking current in the other, such that the circuit is regulated.
