TVS (Transient Voltage Suppressors) diodes or arrays are designed to protect sensitive microelectronics from damaging overvoltages that occur when a transmission line is struck by lightning or energized by an electromagnetic pulse (EMP). TVS315SM is a metal oxide varistor (MOV) based surge suppressor typically designed for protecting the 5-28V DC system outputs used in automotive, audio, I/O and communications systems.

The TVS315SM is designed to operate at the interface of a power or data transmission line and ground, where it can dissipate damaging voltage the moment it is triggered on. The TVS315SM provides a fast response time at 5ps typical, which will be much faster than the response time of an RC snubber network. The device operates at multiple solder points in order to ensure that the voltage spike is absorbed and dissipated across the entire circuit.

This diode has a forward voltage drop of 1.5V at 5 amps, with a 1000W pulse rating and a 5.5Ω on-resistance. The device has a very low reverse voltage rating (5V) to ensure that the transient voltage does not interfere with sensitive electronics. Additionally, it has a breakdown voltage of 15V and can be used up to a 28V system. The device has an operating temperature range of -55°C to +125°C.

The basic workings of TVS315SM are quite simple. Once a voltage surge occurs, the device senses it and quickly triggers on. This causes the diode to become forward biased and dissipate the current to the ground, thus diverting the damaging EMF or ESD away from the sensitive electronics. It then quickly returns to its non-conductive state to wait for the next voltage spike. Its fast response time ensures that the voltage spike does not damage any of the electronics components that it is protecting.

The TVS315SM device is widely used in automotive, audio, I/O, communications, and other systems where a fast response time and reliable protection is required. It is especially well-suited for protecting against overvoltage transients produced by sudden changes in inductance, such as lightning strikes or conducted ESD events. The device is well-built and provides ultimate protection to sensitive circuits. It is an excellent choice for protecting your equipment against unwanted power surges or voltage transients.
