Transient Voltage Suppressor (TVS) diodes, also known as unidirectional Ultra Fast Technology (UFT) devices, are a variant of silicon (Si) avalanche diodes. Developed from technology advancements in the 1970s, TVS diodes are commonly used for surge protection of either electronic components or electronic circuits.

824540581 is a TVS diode specifically designed for transient voltage and ESD (electrostatic discharge) protection of power supplies, data lines, and I/O ports. The 824540581 is equipped with a very low clamping voltage, making it more effective than other TVS diodes when it comes to protecting delicate components in the presence of over-voltage transients.

At the core of the 824540581 is an integrated circuit (IC) consisting of electronic components such as resistors, transistors, diodes, and capacitors on an insulating quartz substrate. The IC is designed to monitor the voltage on the incoming signal and, should an overvoltage above the clamping threshold occur, rapidly clamps the excess voltage. Once the overvoltage dissipates, the diode then releases the clamped voltage to its pre-transient state.

On the electrical side, the 824540581 has a maximum peak pulse power of 530W, a clamping voltage of 6.1V, and a peak pulse current of 2.5A for a 10/1000μs pulse width. The operating temperature range is -55°C to +150°C. It is offered in a SOD-323 package, which includes the diode, the package, and its cooling element.

Overall, 824540581 is the ideal TVS diode for transient and ESD protection given its small size, fast response time, and low clamping voltage. The diode activates instantly when an overvoltage enters its protection area, and then returns to its normal operating parameters after the pulse dissipates. Moreover, its robust design ensures that any transient voltage or ESD strike can be effectively absorbed, so as to protect sensitive components from damage.
