Other characteristics, such as maximum repetitive reverse voltage (VRRM), maximum forward current (IFM) and maximum reverse leakage (IRL), for the LL4148-13 are 1.0V, 0.2A, and 50uA respectively. The diode has a junction-to-ambient thermal resistance of 3.7°C/W.

The LL4148-13 can be used in a variety of applications, such as voltage regulation, load current switching, signal switching, and signal rectification. For these circuits, the diode’s glass-sealed enclosure is advantageous since it acts as a barrier against dust, moisture, and other contaminants. In voltage regulation, the diode is used as a clamp, absorbing any excessive current and preventing damage. In load current switching, it acts as a switch, allowing current to flow in one direction only.

The working principle of the LL4148-13 is simple yet effective. When the forward bias voltage is applied, the diode becomes conductive and electrons from the anode move to the cathode. This movement creates an electric field across the junction that is strong enough to repel any further electrons from travelling in the opposite direction. This process allows the LL4148-13 to rectify the current effectively, forming a barrier against reverse current.

The LL4148-13 is the perfect single rectifier diode solution for a variety of applications. Its impressive combination of features and properties, such as the low forward voltage, junction-to-ambient thermal resistance, and anti-saturation protection, makes it a viable option. Furthermore, its small signal diodes composed of phosphor bronze along with its glass-sealed enclosure allows it to function properly in various types of circuits.
