TVS (Transient Voltage Suppressor) diodes serve as the main component of automotive electrical systems. The MXSMCGLCE75AE3 is a specific type of surface mount TVS diode with high-transient surges and high load currents for protection against surges, spikes, and EMI from transients and load current.

The MXSMCGLCE75AE3 can handle up to 75A of peak pulse current at +175°C and can operate from -55°C to +150°C. Its peak surge energy rating is also excellent, reaching a maximum of 280J at +85°C. It is typically designed for use in automotive systems, and is ideal for protecting the critical components of an automotive system against fast-rising peak inrush currents and other transient problems.

The MXSMCGLCE75AE3 achieves its reliable performance through three main components: the cathode, anode, and output junction. The anode is the dominant current path, while the cathode provides the necessary reverse protection. Between the anode and cathode is a large-area output junction that provides an extremely low turn-on voltage, enabling the diode to abruptly respond to transient conditions.

In addition, the enhanced-silicon nitride passivation layer reduces the number of soft failure points and increases the withstand of steady-state temperatures. It also offers excellent reliability and operational temperature range thanks to its extruded body and built-in heat sink.

When a transient event such as a surge or spike occurs, the MXSMCGLCE75AE3 will instantaneously conduct current away from the system, thus protecting the sensitive components from permanent damage. The diode will also clamp voltage to a value which is below that which could cause damage to the system components.

In order to maximise protection, the MXSMCGLCE75AE3 can be used in combination with a Coefficient of Performance (COP) that is designed to maximise the frequency and duration of the surge pulses that the diode can protect against. The COP features adjustable clamping levels and optimal attenuation of high frequency signal transmission noise.

All of the features of the MXSMCGLCE75AE3 make it an ideal choice for automotive systems. Its surface mount design ensures that it can be easily integrated into most existing systems, while its high-transient surges and load current capabilities make it an ideal choice for protection against surges, spikes, and EMI from transients and load currents. Additionally, its adjustable COP allows the user to customise the diode for their individual needs, providing the ultimate in protection for automotive components.
