TVS - Diodes

TVS (transient voltage suppression) diodes are a special type of diode used in the protection of electrical circuits and components from high-voltage power surges. They are commonly employed in areas such as telecommunications, automotive electronics, medical equipment, safety system electronics, consumer electronics, power networking, and home entertainment. TVS diodes are designed to reduce the risk of component destruction by preventing transient voltage spikes from occurring. The BZW04-342BHA0G is a type of TVS diode that offers a range of features, including a wide operating voltage range, high peak power rating, and excellent durability.

BZW04-342BHA0G Application Field and Working Principle

The BZW04-342BHA0G TVS diode is suitable for high-speed data line network protection. It has a wide operating voltage of 6.5V to 28V and a peak power rating of 3.5kW (transient 10/1000s). It is also highly durable, with a maximum junction temperature of 150C and a maximum reverse leakage current of 2.5V. The BZW04-342BHA0G has a symmetrical reverse breakdown voltage of 5V and a maximum clamping voltage of 11V.

The BZW04-342BHA0G is a reverse-biased diode that applies a reverse bias voltage to the anode and cathode of the diode junction. This creates a space charge region between the n-type and the p-type material of the junction, and a built-in electric field with strong electric field concentration. When the high-speed data line encounters a current surge, the diode quickly absorbs the transient voltage and keeps the current below a certain level. This allows the device to protect the line from surge currents higher than normal without damaging the circuit.

The BZW04-342BHA0G is designed to protect up to four channels simultaneously for high speed data lines. The device can be used in a wide range of telecommunications, consumer electronics and automotive safety systems. The device is also compatible with a variety of logic gates, such as NAND, NOR, OR, and XOR, and is designed to be compatible with a variety of professional development systems.

The BZW04-342BHA0G also provides excellent ESD (electro-static discharge) absorption capabilities. The device offers a total absorption of up to 15kV, and is capable of providing a clamping voltage further reducing the stress across the protected line.

In summary, the BZW04-342BHA0G TVS diode is a low cost solution for protecting sensitive components and electrical circuits from a range of sudden power surges, and is suitable for a variety of applications. This device features a wide operating voltage, high peak power rating, excellent durability, and provides excellent ESD protection. The device is suitable for high-speed data line protection, and can be used in a variety of applications.
