TVS - Diodes

TVS diodes (Transient Voltage Suppressors) are used in electrical and electronic circuits to protect the circuit from damage caused by transient surges or "spikes" in voltage - much like a surge protectors found in most houses or buildings. They are typically manufactured as either a unidirectional or bidirectional device and can be placed in circuits to provide overvoltage protection in either direction. TVS diodes are designed to react quickly to an overvoltage condition and discharge the stored or cumulative energy from the transient event. The MR2535L is a popular type of unidirectional TVS diode.

Application Field of MR2535L

The MR2535L is specifically designed for power supply overvoltage protection. This device was intended for circuit applications where there is a chance of an overvoltage condition, such as in on-board embedded systems where an unexpected power supply adjustment could cause a voltage spike that could damage the circuit. The MR2535L is also well-suited for a compact design, which is beneficial for applications such as telephone and automotive infotainment systems.

Working Principle of MR2535L

The MR2535L operates according to the principle of a breakdown diode. It features a high blocking voltage and low on-state voltage drop. As the voltage across the MR2535L increases, it reaches a breakdown voltage (Vbr) at which point the current begins to increase exponentially and the diode enters a breakdown conduction mode. As the current increases, the diode discharges the excess energy from the transient event until the end of the operation. This ensures that the critical components of the circuit are protected from the voltage spike.

The MR2535L is equipped with protection circuitry against thermal runaway. The device is designed to operate in a range of -55°C to +125°C, making it well-suited for most operating environments. In addition, the diode features a high peak surge current and an ultra-fast response time, making it well-suited for high frequency transient events.

Conclusion

MR2535L TVS diodes are a reliable means of protecting sensitive electronics from overvoltage conditions. The protection circuitry helps prevent thermal runaway and the ultra-fast response time ensures quick protection in the event of a voltage spike. The MR2535L is commonly used in power supply protection applications and is suitable for embedded systems as well as automotive infotainment systems.
