70MT120KB

Diodes are often used to convert an alternating current (AC) of one voltage level to a direct current (DC) of a different voltage level. This process is called rectification. Bridge rectifiers are perhaps the most common type of rectifier used in AC-to-DC conversion. The 70MT120KB is a full-wave bridge rectifier, designed for high current applications.The 70MT120KB uses four diodes connected in a bridge configuration, allowing the AC voltage to be presented to the bridge terminals, with the DC output taken from the diagonally opposite terminals. This configuration allows the full cycle of the AC voltage wave to be rectified.The 70MT120KB is most commonly used in applications that require high current power supplies and provides conversion of high input AC voltages to low DC output voltages. Typical applications for the 70MT120KB include:

• Uninterruptible Power Supplies (UPS): The 70MT120KB is commonly used in UPS systems to convert the incoming AC voltage to a lower DC voltage, used to power its own electronics and to charge its battery bank.
• Power Conversion: The 70MT120KB is also used to convert AC main voltages to DC lower voltages, for use in industrial equipment, such as welding machines, medical imaging equipment, and heating systems.
• DC Motors: The 70MT120KB is commonly used to provide power to DC motor control systems.

The 70MT120KB features a low forward voltage drop and offers a current rating of up to 120 amps and a blocking voltage of up to 700 volts. It has a peak repetitive reverse voltage of 1400 volts and a non-repetitive peak reverse voltage of 2000 volts. It has an operating temperature of -25°C to +100°C.The 70MT120KB includes a heatsink to dissipate heat generated by the bridge rectifier and ensure reliable operation. Proper heatsink installation is highly recommended, as it helps to increase the working life of the bridge rectifier. The bridge rectifier must also be securely mounted to prevent any vibration or shock from damaging the device.In conclusion, the 70MT120KB is a full-wave bridge rectifier designed for use in high current applications. It offers a peak repetitive reverse voltage of 1400 volts, a non-repetitive peak reverse voltage of 2000 volts, and a low forward voltage drop. The 70MT120KB includes a heatsink and is commonly used in UPS systems, industrial equipment, and DC motor control systems.
