TVS Diodes, also known as Transient Voltage Suppressors are commonly used in protecting sensitive circuits. They are generally applied where equipment is exposed to overvoltage, surge current, and ESD. The DLP03LC-7 from Microchip is a bidirectional TVS Diodes specifically designed for transient overvoltage protection.

The DLP03LC-7 provides protection of data lines from ± 16kV of contact discharge (human body model) and ± 30kV of air-gap discharge. With 600 W peak pulse power (tP = 8/20 μs), the device helps protect automotive electronics and other automotive systems. This Transient Voltage Suppressor has a Leakage Current that is very low at 30 nA (maximum). Its operating temperature is -55°C to 155°C.

The operating principle of the DLP03LC-7 is simple and effective. It takes advantage of the properties of a diode-capacitor element to absorb transient energy overvoltages while passing normal operating voltages. Essentially, when overvoltage transients occur, the TVS diode provides a low-impedance current path to the ground while the capacitive element charges to the threshold voltage. When the transient voltage drops to a safe level, the diode ceases to appear low impedance. The absorbed energy is stored on the capacitive element, allowing the diode to resume its low impedance state until the capacitive element is discharged.

This makes this Transient Voltage Suppressor an ideal choice in applications that expressively expose the target system to electrical transients, such as automotive, industrial, or telecom applications. It is used in automotive systems for controlling door locks, air conditioners, and GPS navigation, as well as in smart phones, power supplies and other consumer electronics.

Overall, the DLP03LC-7 from Microchip is a low-cost, high-power TVS diode specifically designed for meeting the transient surge requirements in the automotive marketplace. It provides protection from overvoltage, surge current, and ESD, and is a reliable choice for protecting sensitive electronic components and circuits from transient voltage transients.
