MP4KE56CAE3 is a high performance unidirectional Transient Voltage Suppression (TVS) diode. This diode is designed specifically for Automotive and Telecom application to protect against transient over-voltage up to 156V. It is a low capacitance device with excellent surge characteristics for protection against lightning-induced over-voltage. This diode is available in the SOT23 package with the following features:

• Low Stand-off Voltage : 5.5V
• Low Capacitance : 0.25pF Turn-on Voltage
• Breakdown Voltage of 56V
• Clamping Voltage of 79 V
• ESD Protection : ±8KV
• High Temperature : -55°C to 125°C

The MP4KE56CAE3 is designed to respond to extremely high-speed transients in automotive applications. The diode has an operating voltage range from -55 to 125°C. It can also protect sensitive electronics from high-voltage transients up to 156V. The TVS diode has a very low capacitance of 0.25pF, which enables it to respond quickly to transients in automotive and telecom applications.

MP4KE56CAE3 TVS diode works on the principle of Zener avalanche. When an over-voltage transient is applied to the diode, it will start to create a Zener breakdown and an avalanche breakdown, in parallel. The Zener breakdown will cause the diode to clamp the voltage at the set breakdown voltage, while the avalanche breakdown creates a low-impedance path to dissipate the unwanted transients.

In automotive applications, the MP4KE56CAE3 is used to protect sensitive electronics against transient over-voltages. In telecom applications, it is used to protect against surge transients. It can also be used to protect against transient over-voltages in power supplies, motor control systems, and other sensitive electronics.

The MP4KE56CAE3 is ideal for automotive and telecom applications due to its low capacitance, breakdown voltage, and its excellent surge characteristics. The diode is available in SOT23 packages which allows for easy installation and incorporation in applications.
