TVS-diodes, also known as transient voltage suppressors, are used in a variety of applications where transient voltage, caused by lightning, power line surges, and other high-energy sources, can damage other components in the system. The SRDA3.3-4BTG is one such TVS diode, designed to protect against reverse surge currents of up to 4A.The SRDA3.3-4BTG TVS diode is a RoHS-compliant, low-profile, two-terminal device that features an integrated antiparallel diode. It is primarily used as a reverse current protection device in automotive, computer, industrial, and telecom applications. The device is available in a variety of packages to meet the needs of various designs, including SOD-323-1, SC75-1, SC76-1, SOT-23-3, and SOT-223-3.The SRDA3.3-4BTGTVS diode is designed to protect sensitive components from reverse current surges and overvoltage conditions caused by load dump, electrostatic discharge (ESD), fast transients, or power line abnormalities. It features a fast-response time of less than 1ns, making it ideal for protecting low-impedance circuits. The device is optically isolated to reduce crosstalk and inductance, and its built-in Zener diode ensures ESD-protected voltage is maintained during transients.When the SRDA3.3-4BTG TVS diode is triggered, it limits the voltage applied to the protected circuit while maintaining a low clamping voltage. When the transient voltage has been reduced, the diode automatically recovers its normal operating condition and can switch to any voltage from 0 to 6V.The SRDA3.3-4BTG TVS diode features an integrated holding current discharge circuit. This ensures that no surge current can flow uncontrollably through the protected components, preventing any further damage. The device also features thermal shutdown protection and an adjustable voltage selection, allowing it to be configured for use in different applications.In addition to protecting against reverse surges, the SRDA3.3-4BTG TVS diode provides protection against ESD, neutral-to-ground transients, lightning transients, and power line noise. It is designed to guarantee robustness and reliability in all operating conditions.The SRDA3.3-4BTG TVS diode is a suitable choice for protecting sensitive circuits against transient voltage spikes and overvoltage conditions. With its integrated antiparallel diode and adjustable voltage selection, the device offers excellent protection against reverse current, ESD, fast transients, and power line noise. Its fast response time, low-profile package, and easy-to-install design make it the ideal choice for a variety of automotive, computer, industrial, and telecom applications.
