Transzorb-Voltage-Suppressors (TVS) are diode-based devices used for protective purposes in systems that handle high voltage and current. The SMCJ24CE3/TR13 is a suitable device for this application because of its low clamping voltage and high surge current rating. This article will explain the application field and working principle of the SMCJ24CE3/TR13.

The SMCJ24CE3/TR13 is an ultra-fast bidirectional transzorb with an integrated resistor. It is designed to protect voltage sensitive equipment from electrostatic discharge (ESD) and transients. The device has a IEC 61000-4-2 compliance rating of 8 kV (Contact Discharge) and a UL94 V-0 flammability rating. The peak pulse power it can dissipate is 3.5 kW (10/1000 μs waveform) and its maximum clamping voltage is 17.2V (8/20 μs waveform). It can also handle up to 24A of surge current (8/20 μs waveform). All of these features make it an ideal choice for applications involving high-voltage and current transients.

The working principle of a TVS diode involves the conduction of a voltage-dependent rectification process. When the breakdown voltage is exceeded (due to an overvoltage event), the diode will become forward-biased and will conduct current for the duration of the voltage spike. This current is then managed by the integrated resistor to reduce the power dissipation of the device, while still preventing the voltage from exceeding the breakdown voltage. The most commonly used TVS diode architecture is the Zener diode, which relies on avalanche breakdown for its operation.

The SMCJ24CE3/TR13 is a great device for systems that require fast response time and high surge current ratings. It is well-suited for automotive, computer, industrial, medical, and telecommunication applications. It can also be used for transient voltage suppression in power supplies, mobile phones, personal communication equipment, and standard logic interfaces. The SMCJ24CE3/TR13 is a great choice for systems that require an ultra-fast response time and a large surge current rating.
