• TVS - Diodes Overview
  • TVS - Diodes are small chips that protect sensitive electronic devices from high voltage transients or electrical surges that can damage or destroy the connected devices.
  • Generally, the TVS diodes are designed to protect sensitive electronic devices from high voltage transients or electrical surges that are too large for traditional overvoltage protection devices to handle. The protection provided by TVS diode may be from any of the following conditions: Electrostatic Discharge (ESD), Lightning (Surge) Induced Electric Field (LIFE), Lightning Electrostatic Discharge (LED), Transverse Electromagnetic Pulse (TEM), and Heavy Current Impulse (HCI).
  • TVS diodes are available in a wide range of voltage and current ratings. The voltage ratings generally range from 1V up to 800V and the current ratings range from 5mA up to 30A. They also come in a variety of packages, such as SOT23, SMA, and SOD, as well as surface-mount and through-hole varieties.
• SMBJP6KE56CA-TP Application Field and Working Principle
  • The SMBJP6KE56CA-TP is a Transient Voltage Suppressor (TVS) diode from the SOT-23 family of TVS diodes. It has a peak pulse power rating of 600 watts and a breakdown voltage of 56V. The TVS diode also has a low capacitance rating of 18pF.
  • The SMBJP6KE56CA-TP TVS is suitable for protecting sensitive electronic devices, such as Integrated Circuit (IC) chips, from electrostatic discharge (ESD), lightning (surge) induced electric field (LIFE), lightning electrostatic discharge (LED), transverse electromagnetic pulse (TEM), and heavy current impulse (HCI). The SMBJP6KE56CA-TP can also be used as an overvoltage protector for various AC or DC circuits.
  • The working principle of the SMBJP6KE56CA-TP is quite simple. It is a zener diode that is designed to conduct current in reverse direction as soon as the applied voltage exceeds the breakdown voltage. As soon as the voltage exceeds the reverse breakdown voltage, the diode begins to conduct, which is why it is referred to as a “TVS diode”. By conducting this current, the diode is able to protect the connected IC chip from being damaged by the high voltage transients.
  • The SMBJP6KE56CA-TP TVS diode is available in a small SOT-23 package, making it suitable for various mounting applications. Additionally, the diode is also RoHS compliant, which means it is free of hazardous substances and does not contain any lead.
