TVS - Diodes

The SM6T39A-M3/5B is a member of the TVS (transient voltage suppression) diode family. It has some unique characteristics in that it can be used to suppress both alternating and unidirectional transient voltages. As a result, the diode can be used in multiple applications to protect against voltage spikes.

Description

The SM6T39A-M3/5B is a small-sized, bidirectional, low-capacitance transient voltage suppressor diode. It is rated for a maximum peak pulse power rating of 600W and a maximum repetitive peak voltage rating of 600V. The diode is composed of PN junction die. It is available in a SOT-23 package.

Features and Benefits

The SM6T39A-M3/5B offers a variety of features and benefits. The diode is rated for a high peak pulse power rating, meaning it can handle large voltage transients without damaging the diode. The diode also has a low capacitance rating, meaning that it can provide low voltage ringing, minimizing interference to any nearby circuitry. Finally, the SOT-23 package helps to reduce the board space used and makes the device ideal for automotive and industrial applications.

Applications

The SM6T39A-M3/5B is primarily designed for ESD (electrostatic discharge) protection and other transient applications. It can be used in automotive and industrial applications that require protection against voltage spikes. It can also be used for protecting electronic devices against ESD, lightning strikes, and other voltage transients. Additionally, the diode can be used for protection in high-speed telecommunications equipment such as LANs, modems, and optical fiber systems.

Working Principle

The SM6T39A-M3/5B utilizes a PN junction die to control the flow of current. The diode uses the principle of reverse voltage blocking. When no voltage is present, the diode is forward biased and no current flows. When a voltage is applied, the diode is reverse biased and starts to conduct current. The diode has a predetermined breakdown voltage, once this is reached the diode conducts current and the voltage is suppressed. This allows the diode to protect from ESD and other voltage transients.
