Transient voltage suppressors are an essential component in electrical circuits that help to protect sensitive electronics from voltage spikes and surges. The SM15T39AY is a particular type of transient voltage suppressor that offers several benefits over other options on the market. In this blog post, we will explore what the SM15T39AY is, how it works, and its unique features and benefits.

What is the SM15T39AY?

The SM15T39AY is a transient voltage suppressor that is designed to protect sensitive electronic devices from transient voltage spikes and surges. It operates through the use of a low-impedance avalanche breakdown diode that can handle sudden high currents. The SM15T39AY is specifically designed to provide ESD and surge protection in applications with high operating voltages, making it a popular choice for use in products such as LED lighting, automotive electronics, and power supply systems.

How does the SM15T39AY work?

The SM15T39AY operates using a mechanism called avalanche breakdown. This mechanism allows the SM15T39AY to handle sudden high currents and voltage spikes that may occur in electrical circuits. Essentially, when an excessive voltage is applied to the device, the SM15T39AY will breakdown into a low-impedance state, allowing current to flow through it and bypass the sensitive electronic device. By limiting the voltage that reaches the sensitive device, the SM15T39AY helps to protect it from damage.

What are the features and benefits of the SM15T39AY?

The SM15T39AY offers several unique features and benefits that make it a popular choice for use in various electrical applications. Some of these features and benefits include:
