TVS - Diodes are vital protection devices designed to protect electrical systems from damage caused by lighting and electrostatic discharge (ESD). The SMBJ250CAE3/TR13 is a unidirectional 400 Volt Transient Voltage Suppressor Diode, manufactured by Taiwan Semiconductor. It is an ideal protection device for use in multiple applications, and a popular choice for voltage-related protection projects.

Application fields:

The SMBJ250CAE3/TR13 offers reliable protection from overvoltage transients and voltage spikes, and is used in a variety of applications. These include consumer electronics, automotive, telecommunications, networking systems, powered circuits, embedded systems, and more. The diode is designed to protect voltage sensitive components such as micro boxes, microcontrollers, analog to digital converters, audio amplifiers, signal processors, power supply modules and other similar devices.

Working Principle:

This diode works by diverting excess electricity from a voltage surge away from sensitive components. The diode is able to protect against surges by rapidly switching on (conducting) when a voltage spike exceeds a predetermined level. This causes the voltage to reduce and the component to be protected from any damage. This surge protection is effective when the voltage spike exceeds 400V. The SMBJ250CAE3/TR13 is rated to have an excellent Peak Pulse Current such as Ipp = 65A and an Average Forward Current of Iavg = 0.5A.

Advantages:

The SMBJ250CAE3/TR13 offers various advantages, including its low profile package, high Ipp rating and an operating temperature of -55 °C to +150 °C. Its quick electrical response against voltage transients and surges also help to protect delicate components from damage. The SMBJ250CAE3/TR13 is a suitable choice for applications where a low physical footprint is required.

Usage Recommendation:

When using the SMBJ250CAE3/TR13 in any application, it is recommended to be aware of its power rating, and to avoid any overloading of the diode. It is also recommended to couple the diode with a suitable sized capacitor for effective surge suppression.

Conclusion:

The SMBJ250CAE3/TR13 is an excellent Transient Voltage Suppressor Diode and is designed to provide reliable protection against surges and transients in a variety of applications. It provides rapid response to unexpected voltage transients, and is capable of handling up to 400V without causing any damage to sensitive components.
