Diodes - Rectifiers - Single is a general class of electronic components that act as a check valve in the flow of electrical current. The JANTX1N1190 is a single diode rectifier designed for high voltage operation, typically mounted on circuit boards for power applications and other related uses. Its applications include motor drive systems, AC and DC switching power supplies, and inverters.

Device Overview

The JANTX1N1190 is a single diode rectifier with a maximum power dissipation of 900mW. It is built in a plastic package with a ceramic housing and has a total capacitance of 10pF. It is available in a variety of packages, including a 3-pin through-hole (TO-226), 4-pin through-hole (TO-220) and hermetically sealed configurations. It also comes with a junction temperature range of -55 to 125 degrees Celsius.

Device Terminals

The JANTX1N1190 has three terminals: an anode (+), a cathode (-) and a case/common terminal. The anode connects to the positive terminal of the source voltage, while the cathode connects to the negative terminal of the source voltage. The case/common terminal is the commonly connected to ground or other reference potential. The device should be installed in a suitable heat sink to ensure adequate heat dissipation.

Reverse Recovery Characteristics

The JANTX1N1190 has a reverse recovery time of 40ns. This is the time taken by the diode to recover from a forward to a reverse state after the application of a reverse bias. This is an important parameter as it affects the overall performance of the device. A longer recovery time can lead to increased power dissipation.

Thermal Considerations

The JANTX1N1190 is designed for use in high voltage applications and therefore must be installed with a suitable heatsink to ensure adequate heat dissipation. The heatsink must be designed to provide sufficient area for heat transfer from the device to the air, and this area should take into account the ambient temperature, the thermal resistance of the package, and the maximum junction temperature of the device. It is also important to ensure that the heatsink is firmly attached to the surface the device is mounted on.

Working Principle

The JANTX1N1190 is a single diode rectifier, used primarily in high voltage applications. A diode behaves as a one-way valve, allowing current to flow in one direction while blocking current from flowing in the opposite direction. With the JANTX1N1190, a forward voltage is applied to the anode, which causes electrons to be injected into the diode’s junction. They are then carried across the junction by the applied electric field and deposited on the other side. If a reverse voltage is applied, then the electric field is reversed, causing the electrons to be pushed away from the diode’s junction and blocking the current from flowing.

Applications

The JANTX1N1190 is primarily used in AC and DC switching power supplies and inverters. It can also be used for motor drive systems, high-voltage AC/DC converters, DC/DC converters and uninterruptible power supplies. Due to its fast reverse recovery time, it is also suitable for use in high-frequency rectification circuits, such as those used in switch-mode power supplies.

Conclusion

The JANTX1N1190 is a single diode rectifier designed for high voltage operation. It is built into a plastic package with a ceramic housing and has a reverse recovery time of 40ns. Its applications include motor drive systems, AC and DC switching power supplies, and inverters. It must be installed in a suitable heat sink to ensure adequate heat dissipation.
