TVS-Diodes are designed to protect semiconductor junctions against destructive image and voltage transients. The MXSMCG9.0CA transient voltage suppressor diode is a medium power V-I device designed specifically for use in high voltage applications. It is constructed of an N-channel silicon epitaxial diode with an electrolytic capacitor in series, which is the protection element.

The MXSMCG9.0CA is designed to withstand high voltage, high transient energy pulses without performance degradation. It is rated to handle up to 3500 V transient energy pulses and has 1500 V reverse breakdown voltage. The MXSMCG9.0CA is also capable of handling up to 4400 V transient energy pulses with a 220 V reverse breakdown voltage. The device has a very low leakage current and is effective across a wide temperature range.

The MXSMCG9.0CA is used in a wide array of applications, most notably in television, set-top boxes, cellular phones, navigation units, and satellite receivers. In addition to protecting the electrical components from transients, the device can also reduce the entering of stray signals into the circuit that could cause accidental triggering of active components. This helps protect against dangerous power surges.

The working principle of the MXSMCG9.0CA is based on a triggering circuit that senses a transient voltage and then applies an opposing voltage across the diode. This opposing voltage is regulated by an external bias voltage. The triggering circuit is triggered by a sudden change in the applied voltage. When a transient voltage is detected, the MXSMCG9.0CA activates the trigger circuit, which in turn causes the opposing voltage to be applied to the diode. This opposing voltage ‘shunts’ the transient voltage and dissipates the energy across the diode.

The MXSMCG9.0CA is engineered for long life and provides excellent transient protection in a wide range of applications. The device is cost effective and is suited for both new and existing products that need upgraded performance and reliability. Its high voltage performance and its wide temperature range make it an ideal choice for designers of high voltage applications such as TVs or set-top boxes.
