Working Principle

TPD4E02B04QDQARQ1 utilises TVS technology to protect circuits from transient overvoltage events. The device works by clamping or redirecting the transient voltage energy away from the protected electronics. A TVS diode is made up of a PN-junction diode with an avalanche breakdown voltage that is carefully designed to have a clamping voltage that corresponds to the value of the overvoltage surge that needs to be absorbed. The diode acts like a voltage-dependent resistor that can absorb the excess voltage and current and clamp it within the design limits.

When the transient overvoltage occurs, the avalanche breakdown voltage of the TVS diodes is exceeded, resulting in a voltage drop across the diode with a corresponding rise in current. The voltage and current of the transient overvoltage is then dissipated as heat by the devices built in thermal protection circuitry. This effectively absorbs and redirects the energy away from the protected circuitry.

TPD4E02B04QDQARQ1 is designed to provide high-level protection for sensitive electronics. It is capable of withstanding multiple transient events of up to ±30kV/2.2A, making it an ideal choice for applications that require reliable and robust protection.
