TVS (transient voltage suppressor) diodes are one of the most commonly used components in device protection and signal integrity applications. The SMBJ75A-13 is a unidirectional diode designed to protect sensitive electronics from electrostatic discharge and transients.

This TVS diode from Diodes Incorporated is designed to protect against voltage transients in excess of 400W, allowing it to protect components in automotive, industrial, and consumer electronics applications. The SMBJ75A-13 is suitable for use in a variety of voltage applications, from as low as 6.8V up to a maximum of 75V. It is available in a variety of package sizes, ranging from the SOD-123 to the TO-220.

The SMBJ75A-13 is a unidirectional diode, meaning that it only allows current flow in one direction. In an ESD (electrostatic discharge) event, the SMBJ75A-13 will rapidly clamp the voltage to a safe level, protecting the device against damage from electrical transients. It can safely dissipate energy up to 400W, providing excellent surge protection for a variety of electronic applications.

The SMBJ75A-13 also has a working principle known as “clamping”. In normal operation, the device has a low forward voltage drop. However, in the event of an electrostatic discharge, the device reacts by rapidly increasing its forward voltage drop, essentially “clamping” the voltage to a safe level. This clamping action prevents damage to the protected components from overvoltage conditions.

The SMBJ75A-13 is an excellent choice for a wide range of applications. It is suitable for use in automotive, industrial, and consumer electronics applications. It can also be used to provide protection for data and signal lines, including USB, HDMI, and Ethernet. Its low profile and low forward voltage make it an ideal choice for circuit protection.

The SMBJ75A-13 is an effective and reliable device for protecting sensitive components against surge and transient events. Its unidirectional design and clamping action provide excellent protection up to 400W, making it a suitable choice for a variety of applications. The device’s wide range of operating voltages and package sizes make it a versatile choice for ESD and transient protection.
