TVS (transient voltage suppressor) diodes are designed to protect sensitive electronic devices from high voltage, excessive energy, and electrical discharges. SMDA03-6/TR13 diodes, which are part of the TVS family, are specifically designed to protect against high electrostatic discharges, or ESD. ESD is caused when two objects—such as a human and an electronics component—create a sudden surge of electrical charge that can disrupt circuits and damage hardware.

The SMDA03-6/TR13 TVS diode is rated for up to 15kV, making it particularly useful for protecting devices from electrostatic discharge events. The device is designed to “clamp,” or reduce, overvoltage and overcurrent pulses so that they will not damage the equipment or cause components to malfunction. The diodes can also suppress high voltage transients and surges, which can nevertheless cause permanent damage.

The SMDA03-6/TR13 diodes are known for their bilateral symmetry, which helps ensure balanced protection and symmetrical clamping across both terminals. This symmetry helps the device to protect devices in any direction, regardless of whether the equipments is exposed to an incoming transient or produces one of its own. As an added bonus, the SMDA03-6/TR13 diodes are RoHS (Restriction of Hazardous Substances) compliant.

In terms of physical specifications, the SMDA03-6/TR13 diodes measure 5.0 X 4.3 X 4.3 mm, with a maximum peak pulse power of 600W. The device also features a peak pulse current of 5kA and a clamping voltage of 18.5V. The device is constructed of Silicone resin-coated alloy construction that helps ensure its durability and reliability.

When it comes to application fields, the SMDA03-6/TR13 diodes are often used in audio and video circuits, data acquisition systems, RF communication systems, and industrial, automation, and automotive electronics. Additionally, the devices are frequently used in medical technology, home appliances, military and security systems, and consumer electronics like mobile phones and digital cameras.

The working principle of the SMDA03-6/TR13 diode is quite simple. When voltage overshoots the breakdown voltage of the diode—which is typically 8V—the diode activates and starts to conduct current. This allows the overvoltage to “clamp” onto the diode so that it is not able to damage any other parts in the circuit. This process is often referred to as “crowbar” protection.

In summary, the SMDA03-6/TR13 TVS diodes provide protection for a wide variety of electronic devices. The device offers excellent bilateral symmetry and high peak pulse power, and is RoHS compliant. The device is often used in audio and video circuits, data acquisition systems, RF communication systems, industrial, automation, and automotive electronics, medical technology, home appliances, military and security systems, and consumer electronics. When it comes to operation, the device simply “clamps” voltages above 8V to protect the circuit from potentially damaging effects.
