TVS - Diodes

A TVS diode is one of the most commonly used devices for transient suppression and over-voltage protection. It is a unidirectional voltage-dependent device that works by clamping voltage and limiting current in order to reduce surge damage. It is commonly used in automobiles, computers, telecoms, and any other application where physical environmental conditions are likely to change abruptly and voltage transient are expected.

BZW04-20 B0G Application Field and Working Principle

The BZW04-20 B0G surface-mounted TVS diode is specifically designed for transient suppression, over-voltage protection and lightning protection of 12V DC circuit. It is rated at 400 watts peak pulse power (8/20μs) and 10 watts steady state power. This device is suitable for use in AC line filter circuits, AC/DC mains power supply circuits, AC power back-feed filters, lightning protection for personal electronics, DC/DC converter output line ESD protection, and EMC/EMI circuits.

The BZW04-20 B0G TVS diode works in a similar way to other TVS diodes. It has a high surge current capability to quickly pull in and clamp excessive voltage, while its low on voltage enables its clamping voltage to stay near the over-voltage area. In the event of an over-voltage condition, the BZW04-20 B0G TVS diode will effectively shorts the over-voltage to the ground, thereby limiting the current flow through the protected circuit. In this way, the diode will limit continuous excessive transient voltage and protect the connected components against damage.

The BZW04-20 B0G TVS diode is made from a polysulfone reinforced thermoset which has excellent resilience to mechanical stresses such as vibration, shock, and temperature cycling. Its solder heat resistance is also superior, which makes it suitable for use in reflow soldering processes. Furthermore, it has a low leakage current, which ensures high sensitivity for over-voltage transient protection.

To maximize the performance and reliability of the BZW04-20 B0G TVS diode, careful attention should be given to its mounting and soldering processes. The diode must be installed in a vertically orientation. This is important for evenly distributing the heat generated by the diode and proper dissipation to the air. It is also important to properly solder the diode into the circuit board. Poor soldering may lead to electrical instability and malfunction of the protected circuit. More importantly, it may also reduce the diode’s protection performance.

In summary, the BZW04-20 B0G TVS diode is an important component for providing reliable over-voltage protection. This diode is generally suitable for use in various applications such as automotive, computers, telecoms, and any other application where transient conditions are expected. Proper attention should be paid to its mounting process in order to maximize its performance, reliability, and protection performance.
