Introduction

MXLCE28AE3 is a Transient Voltage Suppression (TVS) diode designed to protect against electrostatic discharge (ESD) and over voltage transients. It is suitable for any circuit that need protection from high-level ESD transients or power interference. This diode is designed for use in personal digital assistants (PDAs), cell phones, notebook computers and other handheld electronic devices.

Application field

MXLCE28AE3 is a surface-mount diode designed for ESD protection and voltage transient suppression applications. It is suitable for applications like automobile electronics, mobile phones, PDAs, notebook computers, and other portable consumer electronics products with voltage protection of 3.0 V, which provides ESD protection up to +/-20 kV contact discharge, and high surge protection up to 4A. The device can safely protect the circuits from sudden surges in voltage and current which may be induced by lightning or other EMI sources.

Working Principle

MXLCE28AE3 utilizes a high-speed ESD protection scheme for maximum ESD protection. When an ESD transient is applied, the diode begins to conduct and limit the amount of current that can reach the protected circuit. The maximum peak current that this diode can handle is 4A. It also has a low capacitance of about 0.35pf. As a result, the device provides very low energy ESD protection and low capacitance.MXLCE28AE3 also has a high speed switching capability, allowing it to switch from an off-state to an on-state in less than 1ns. This short response time allows it to react quickly to ESD transients and prevent damage to sensitive circuitry.

Conclusion

The MXLCE28AE3 is an ideal solution for protecting sensitive electronic circuits against ESD transients and over voltage transients. It is suitable for automotive electronics, handheld electronics, and other consumer electronics applications with a 3.0 V voltage protection level. It has a low capacitance of 0.35pf, and a high peak current rating of 4A. In addition, it also provides fast switching time between on and off states.
