TVS - Diodes & SMF58A-T13 application field and working principle

Transient Voltage Suppression (TVS) diodes are devices that protect electronic components from damaging electrical pulses, EMI, and other unwanted surges. This type of protection from over voltage occurrences can come in many different forms; the most common being the TVS diode.

Application fields

The SMF58A-T13 is a medium speed stand alone TVS Diode that offers superior protection against EMI, surge pulses, and over voltage events. This surface mount device is designed to be a replacement for traditional bi-directional TVS diodes, providing capacitive ESD protection for up to 25kV – offering improved surge and EMI performance.

The SMF58A-T13 is suitable for a range of applications such as automotive systems, consumer electronics, medical equipments, industrial equipments and IT applications. It is an ideal choice for protection of sensitive electronic components typically found in these kinds of equipments. It is RoHS compliant for European markets.

Working principle

The SMF58A-T13 is a passive unidirectional TVS Diode, typically constructed of silicon. It is triggered providing protection when a voltage potential that exceeds the diode’s specified maximum working voltage is encountered. The diode then becomes conductive redirecting the potential surge to ground.

The key features of the SMF58A-T13 include low capacitance of 6pF, working voltage of 5.8V, clamping voltage of 8.1V, and a maximum surge current of 14A. The device is constructed to provide ESD protection and is tested to IEC 61000-4-2 (ESD) and IEC 61000-4-4 (surge) requirements.

The key benefits of the SMF58A-T13 TVS Diode are its improved surge performance and the suitability of it being used as a replacement for traditional bi-directional TVS diodes. This device is able to provide both EMI filtering and capacitive ESD protection, ensuring reliable operation and making it a suitable option for use in a range of applications and environments.

As such the SMF58A-T13 is the ideal choice for protecting sensitive electronic components from surges, EMI and other over voltage occurrences, offering improved surge performance and long-lasting reliability against EMI.
