TVS - Diodes

The PESD24VL1BAZ is an integrated circuit (IC) component widely used for transient voltage suppression (TVS) applications. It is part of a class of components known as transient voltage suppressors or TVS diodes. This particular device is a double-sensitive bidirectional TVS diode array in a two-lead, SOT–323 (SC–84A) package, and is suitable for use in applications that require transient voltage protection.

Application Field

TVS diodes, including the PESD24VL1BAZ, are designed to provide a shunt electrical protection from overvoltage events such as electrical transients caused by ESD, lightning or switching transients. This product is useful in high-speed data transmission lines, consumer electronics, automotive, industrial and other applications that require protection from transient overvoltages. These components offer bidirectional protection and are typically used in conjunction with other protection components such as varistors, capacitors, surge protection circuits and accessories to provide an optimum level of protection.

Working Principle

TVS diodes such as the PESD24VL1BAZ are designed with two electrodes – a cathode and an anode. When a transient overvoltage occurs, the device begins to conduct current. This is facilitated by the internal avalanche breakdown effect and generates a current flow. This current flow in then steered through the diode array, allowing it to protect the circuit from voltage spikes. The device is designed with a current rating that can easily absorb up to 400W (5/1000 seconds) of peak pulse power.

Bidirectional protection is provided by the diode device along with internal protection circuits. These circuits help to further reduce overvoltage by controlling excessive current and voltage. TVS diodes are also designed with electrostatic discharge (ESD) protection. This adds an additional level of protection to circuits and components, preventing static electricity from causing damage.

Conclusion

In conclusion, the PESD24VL1BAZ is an excellent component for providing transient voltage suppression. It is ideal for a wide range of applications where protection from overvoltage transients is essential. The device provides bidirectional protection with high peak pulse power ratings and is suitable for use in automotive, industrial, consumer electronics and other applications. It is also designed with additional features, such as electrostatic discharge protection, to further enhance circuit protection.
