TVS - Diodes

TVS (transient voltage suppressor) diodes are an important component of any electronic circuit. They protect sensitive components and circuits from electrical spikes and surges. The SMBJ28D-M3/H is a TVS diode that can be used to protect circuit boards, wiring, and even entire systems from such overvoltage events.

SMBJ28D-M3/H Application Field and Working Principle

The SMBJ28D-M3/H is a dual channel TVS diode. It has a bidirectional configuration to protect components and circuits from surge conditions. It is designed for use in applications such as telecom, networking, and automotive circuits. The SMBJ28D-M3/H is ideally suited for transient protection and other applications that require circuit protection from high energy lightning and electrostatic discharge (ESD) events.The SMBJ28D-M3/H is a unidirectional diode that is designed to protect electronic components from overvoltage by clamping voltages above a certain level. When the voltage on the circuit reaches or exceeds the diode\'s breakdown voltage, the diode turns on, enabling current to flow through it and dissipating the excess voltage as heat. This keeps the voltage on the device within a safe range, protecting the device from overvoltage damage.The SMBJ28D-M3/H is designed to handle up to 28V and can dissipate up to 600W of peak pulse power. It offers a very fast response time and a low clamping voltage. In addition, it is designed to provide overvoltage protection while maintaining a low capacitance. This makes the SMBJ28D-M3/H well-suited for use in high-speed applications, protecting sensitive circuits from transient surges.The SMBJ28D-M3/H can also be used to provide a high degree of protection from ESD. The device is designed to handle up to 30kV of contact discharge and 300V of on-chip ESD protection. This means that the diodes can protect components from being damaged by electrostatic discharge events, such as those created when two components are placed in contact and then separated.Overall, the SMBJ28D-M3/H is a robust and reliable protection device for a variety of applications. Its fast response time and low capacitance, combined with its high ESD protection, make it an ideal choice for protecting components from overvoltage, ESD, and transient surges.
