TVS - Diodes - 1.5KE400CAHB0G Application Field and Working Principle

TVS - Diodes, also known as Transient Voltage Suppression (TVS) diodes, are a special type of semiconductor diode that protects circuits susceptible to surges and voltage spikes caused by electrostatic discharge (ESD). TVS diodes are designed for excellent transient voltage clamping with minimal device capacitance and are designed to withstand larger current events (10 amps to 5,000 amps). As more complex transistor and microelectronic circuits with significant on-chip capacitance are developed, the protection of these circuits is becoming increasingly important. 1.5KE400CAHB0G, is a common type of Transient Voltage Suppression Diodes.

1.5KE400CAHB0G is a unidirectional Transient Voltage Suppression Diodes used in various electronic circuit applications. 1.5KE400CAHB0G diodes are typically used in digital circuit protection, such as computer systems and peripherals, home entertainment systems and mobile phones. These TVS diodes also provide ESD Suppression in High Speed Data Lines in Storage Area Network and Operating System, Protection for Ethernet, USB and Video signals. Additionally, 1.5KE400CAHB0G supplies electrical and ESD protection in power supplies, LVDs, and motherboards.

1.5KE400CAHB0G Working Principle:

A 1.5KE400CAHB0G TVS Diode is a semiconductor diode specifically designed to protect sensitive electronic circuits against large voltage spikes. The device consists of a diode, connected in parallel with a Zener diode, connected in series with a capacitor. When exposed to a high voltage spike, the diode quickly switches on due to the forward biasing of the junction. Once the diode is conducting, the Zener diode instantly starts dissipating the energy of the voltage spike, and the capacitor ensures a constant supply of charge to keep the diode conducting until the spike subsides. If the voltage spike is sustained, the TVS Diode will keep the circuit protected from harm.

In summary, 1.5KE400CAHB0G is a type of Transient Voltage Suppression Diodes used in various electronic applications, from digital circuit protection to high speed data line protection. The TVS diodes are designed to protect sensitive electronic circuits against large voltage spikes. The device consist a diode, connected in parallel with a Zener diode, connected in series with a capacitor that dissipates energy from the voltage spike to keep the diode conducting until the spike subsides. TVS Diodes offer circuit designers assurance of reliable transient voltage protection and circuit isolation.
