JANTX1N649UR-1

Diodes - Rectifiers - Single

The JANTX1N649UR-1 is a single diode rectifier designed with a low forward voltage drop, high surge capability and low leakage current in order to meet the needs of high-current rectifier applications. The device features a glass-passivated chip junction to minimize leakage current leakage and reduce processing through the use of a PN junction. The JANTX1N649UR-1 is ideal for low-loss power rectification and moderate surge current applications, including data communications, central office supplies, endpoint devices, inverters, and power supplies.

Working principle

A diode rectifier is an electrical device which is composed of two terminals and a one-way conducting path, which permits the flow of current in one direction while blocking in the other direction. The anode and cathode pins of the JANTX1N649UR-1 can be identified by their relationship with the embossed pad of the chip. The anode is connected to the anode pad through an internal solder joint on the chip. The cathode is represented by the pad. When a forward bias is applied to the anode-cathode junction, electrons from the anode will pass quickly across the junction towards the cathode side due to the junction\'s relatively low resistance, resulting in a high current flow. Conversely, when a reverse bias is applied to the junction, the diode begins to act as an insulator and the current flow is almost completely blocked.

Application Fields

The JANTX1N649UR-1 has a wide range of applications, including radio frequency (RF) power applications, telecommunications, automotive electronics and consumer electronics. For telecommunications, the JANTX1N649UR-1 is used in an array of applications from central office supplies and endpoint devices, to protectors and line cards. Its low forward voltage drop of 0.325V helps to ensure efficient operation and its high surge capability allows for a longer lifespan and reliable services. In automotive electronics, JANTX1N649UR-1 can be used in applications such as EGR valve controls, electronic ignition, lighting controls, and alternator rectification. Its breakdown-free design also eliminates hot spots and improves the efficiency of power switching. In consumer electronics, JANTX1N649UR-1 is used in a number of applications, such as television and radio receivers, DC to DC converters, portable device power supplies, and inverters. It provides low voltage drop and excellent heat dissipation, allowing portable consumer electronics to have longer battery life, while maximizing efficiency and reducing EMI.
