1.5KE6.8A-E3/51

TVS - Diodes

The 1.5KE6.8A-E3/51 belongs to the general class of TVS diodes (Transient Voltage Suppressor) used to protect electronics from voltage transients. In particular, this device can handle 6.8A Surge, at peak pulse power of 51W, with an operating voltage range of 2.0V to 30V and a stand-off voltage range of 6.5V to 8.5V.

Application field

The 1.5KE6.8A-E3/51 is typically used in applications such as LED lighting, computer peripherals, telecommunications and automotive systems. It provides an effective solution for reducing the risk of power surges and voltage transients damaging circuitry. It can also be used in areas exposed to lightening strikes or other severe power transients.

Working Principle

TVS diodes work by essentially creating a fast protective "gate" across two points when the voltage spike exceeds a certain level. This gate opens and closes quickly, allowing electricity to flow through the diode while blocking surges and transients from getting to the load.

When the voltage spike exceeds the diode\'s clamping level, usually specified in the datasheet, the gate opens and a current is drawn into the junction diodes, protecting the downstream electronics from any consequential high or low voltage damage. The capacitor then dissipates the energy from the spike, returning to a normal level once the spike has passed.
