MASMCJ15CA Application Field and Working Principle

TVS (Transient Voltage Suppressor) diodes are specialized diodes designed to protect sensitive electronics from voltage spikes. The MASMCJ15CA is a Bourns proprietary planar array diode designed for high power handling capacity and AC/DC overvoltage protection. It can protect sensitive electronics from over-current conditions beyond peak voltage.

Application Field

The MASMCJ15CA is ideal for a wide range of applications that require high power handling, bidirectional overvoltage protection, and avalanche performance. These include automotive test equipment, automotive power systems, heavy equipment, light loads, DC/AC power supplies, and DC/AC power systems. The MASMCJ15CA also features a high peak power rating of 1500W and is designed to prevent electrical failures due to overload, over-voltage, or surges in consumer electronics such as computers, monitors, printers, and other electronic equipment.

Working Principle

The MASMCJ15CA is a combination of two distinct technologies. The first is a planar array diode that is designed to protect circuits from overvoltage by combining Reverse Voltage Protection (RVP) and Junction Avalanche Protection (JAP). This planar array diode is combined with a Surge Current diode, which is an array of Schottky barrier diodes specifically designed to protect against transient overcurrents. The Schottky barrier diodes absorb transient overcurrents by providing a low-resistance path to ground. In addition, the Schottky barrier diodes also help to dramatically reduce surge voltage by providing an impedance path.

The MASMCJ15CA is also designed to provide overvoltage support in AC or DC applications. This is achieved through the use of internal clamping circuits and various Zener diodes. The Zener diodes, when combined with internal clamping circuits, protect circuit components from overvoltage. The Zener diodes will help to stabilize the voltage level by dissipating the excess energy whereas the internal clamping circuits will reduce the voltage to a safe level. The MASMCJ15CA also features a “crowbar” protection circuit which will turn off the device in case of an overcurrent condition.

Conclusion

The MASMCJ15CA is an ideal choice for a wide range of applications requiring overvoltage protection and high power handling capacity. Its combination of two distinct technologies makes it ideal for providing protection against surge voltage and transient overcurrents. Its ability to provide AC/DC overvoltage protection, combined with its internal clamping circuits and Zener diodes make it an excellent choice for protecting sensitive electronics from voltage spikes.
