TVS - Diodes are designed to protect sensitive electronic equipment from voltage transients caused by power surges or electrostatic discharge. The SMDA24-6 Transient Voltage Suppressor (TVS) is specifically designed to protect electronic circuits from overvoltage events. It is a surface mount device (SMD) with 24V working voltage and 6V standby voltage.

This device can be used in various applications when surge current protection is required, such as telecommunications, embedded system designs, consumer electronics, automotive electronics, and industrial electronics. Due to its low capacitance, the SMDA24-6 is suitable for high speed applications with data rates over 1GHz.

The working principle of the SMDA24-6 is based on the avalanche breakdown of a PN junction diode. When the device is subjected to a voltage greater than the avalanche breakdown voltage, the diode conducts, thus diverting the surge current into an alternate safe path away from the sensitive circuitry. The breakdown voltage (VBR), clamping voltage (VCL) and peak pulse power (PPP) of the SMDA24-6 are 24V, 35.5V and 600W respectively.

The SMDA24-6 is constructed with an NPN Junction Transistor (JTS) and two N-channel diodes connected in parallel between the JTS collector and the JTS emitter. When a surge hits the device, the N-channel diode is triggered, allowing the surge current to flow through the N-channel diode and away from the sensitive circuitry. When the surge is over, the devices will reset itself and be ready to provide protection against the next surge.

The SMDA24-6 is a highly reliable device and can be used in a wide range of situations. Its high surge life makes it suitable for use in automotive and industrial environments. The device is RoHS compliant and conforms to AEC-Q101 for automotive applications. The SMDA24-6 can also operate from temperatures ranging from -40 to 125°C, making it suitable for use in harsh environmental conditions. The surge current and ESD protection provided by the SMDA24-6 makes it an ideal solution for protecting sensitive circuitry from overvoltage events.
