TVS – Diodes, commonly known as Transient Voltage Suppressors, are voltage regulation components used in electrical and electronic devices that protect circuits against transient voltage and current spikes. The P6SMB82A-M3/5B is a particular type of TVS diode that provides superior protection against electrostatic discharge (ESD) and is designed to fix lightning strike issues. Here, we discuss the application field and working principle of the P6SMB82A-M3/5B diode.

The P6SMB82A-M3/5B is suitable for applications where component and input power protection is necessary thanks to its sturdy construction and fast response time. It’s particularly popular in industrial and automotive applications where reliable electrical protection is essential. It’s also well-suited to protection of high-speed data and line transmission. Applications include power supplies, automotive systems, computers, telecom systems, consumer electronic devices, and more.

As with all TVS diodes, the P6SMB82A-M3/5B increases the threshold voltage of a circuit to protect it from overvoltage damage. The diode works in two ways, depending on the type of event causing the overvoltage. If the overvoltage is caused by a spike, such as a lightning strike, the P6SMB82A-M3/5B acts like a resistor and conducts the spike away from the protected circuit. Alternatively, if the overvoltage event is a sustained, steady-state voltage, the diode acts as a breakdown device and allows a discrete amount of current to flow to ground.

The P6SMB82A-M3/5B features a high peak pulse power dissipation rating of ~7.5kW, ensuring accurate protection from surge & ESD events. It delivers a clamping voltage of ~16V and a reverse stand-off voltage of 7.5V. It has a highly robust leadframe construction, which reduces the dependence of external stress on the functioning of the unit and ensures a long service life. It operates at high temperature with no significant decrease in performance at ambient temperatures up to 175 degrees C, since its design inherently limits temperature related failure.

Given its versatile features and superior surge & ESD protection, the P6SMB82A-M3/5B diode is an effective solution for various applications. It’s a reliable component which ensures sustained optimal performance in circuits by providing maximum protection against transient overvoltage and current surges.
