Electronic components such as transverse voltage suppressors (TVSs) or transient voltage suppressors (TVPs) are essential and invaluable for protecting sensitive electronics from unexpected transients or surges. The SMBJ20A-M3/52 is an ultra-low capacitance-surface mount bi-directional 5.2V Transient Voltage Suppressor (TVS) Diode that is ideal for ESD protection on mobile or portable electronics.

The SMBJ20A-M3/52 is specifically designed to protect delicate semiconductor components from sudden, damaging transients generated by Electrostatic Discharge (ESD). The diode offers excellent clamping capability to protect against strong pulse voltage transients. It has a very low capacitance of about 4.9pF, which helps protect high-speed data interfaces from transient spikes due to ESD. The 5.2V TVS Diode has a peak Pulse Power of 400 W and a peak Oriface Voltage of 6.5V. It provides a low dynamic resistance of 0.2Ω and a typical VBR of 8.2V.

The SMBJ20A-M3/52 is suitable for a wide range of applications, from automotive, aerospace, industrial, peripherals, networking and telecom applications, to computer, consumer and various test and measurement applications. It is suitable for use in power distribution networks, power supplies, active filter circuits, switching regulators, communication systems and circuits with high frequency components.

The working principle and operation of the SMBJ20A-M3/52 is based on Avalanche breakdown. When the diode is exposed to a sufficiently high reverse voltage, electrons in the intrinsic region are accelerated by the applied electric field, resulting in the generation of additional electrons through a process called impact ionization. This eventually causes the diode to breakdown, creating a low impedance between the anode and cathode and preventing any further voltage rise. The diode begins to conduct current in the reverse direction, thereby permitting the current flow to be diverted from the electronic device.

The SMBJ20A-M3/52 is a highly reliable and cost-effective solution for protecting sensitive electronics from transients and surges caused by Electrostatic Discharge (ESD). With an ultra-low capacitance, a peak Pulse Power of 400W and a low dynamic resistance, it provides excellent clamping capability for ESD protection in mobile and portable electronics. The SMBJ20A-M3/52 is suitable for a wide range of applications, from automotive to communication systems, and is a great choice for protecting sensitive electronics from transients and surges.
