In today's technologically advanced world, we deal with electronic devices every day, from smartphones to computers, from cars to home appliances. Electronic devices are very sensitive and require protection against overvoltage or electrostatic discharge (ESD) events. Transient voltage suppressor (TVS) diodes offer protection against these transient events, making them an essential component in electronic designs. In this blog post, we will discuss one of the most popular TVS diodes - SM6T15CA.

What is SM6T15CA?

SM6T15CA is a TVS diode manufactured by STMicroelectronics, designed to provide protection for electronic devices against overvoltage transients. The diode has a unidirectional design and operates at a voltage of 15V. The SM6Txx series is available in various voltage ratings, and the suffix CA indicates a tolerance of ±5% on the breakdown voltage.

How does SM6T15CA work?

TVS diodes work by shunting the excess transient voltage to the ground, preventing the voltage from reaching the sensitive components of the device. When an overvoltage or ESD event occurs, the TVS diode activates, and its resistance decreases, providing a low-impedance path to the excess voltage. This action protects the device from the transient event and maintains its normal operation.

SM6T15CA has a breakdown voltage of 15V, which means that the diode starts conducting when the voltage across it exceeds this value. The diode has a low clamping voltage, which is the maximum voltage it can handle before the voltage spikes occur. The clamping voltage is essential for the protection of the device since it determines the voltage level that the sensitive components can handle.
