Littelfuse 1-Element Uni-Directional TVS Diode 1.5 kW Peak Pulse Power, 2-Pin DO-201 Package 1.5KE6.8A

The Littelfuse 1.5KE6.8A is a 1-element uni-directional Transient Voltage Suppression (TVS) diode designed to protect sensitive electronic components from voltage transients such as lightning-induced surges. It features a peak pulse power dissipation rating of 1.5 kW at the 10/1000µs waveform, suitable for high energy transient suppression in electronic circuits. The device uses a glass passivated chip junction housed in a DO-201 through-hole package that enables robust mounting and mechanical durability.

Its uni-directional configuration protects circuits by clamping voltage spikes quickly with a clamping voltage of 10.5 V, preventing damage downstream. The diode operates across a wide temperature range from -55°C to 175°C, making it reliable for harsh industrial and commercial environments. It is constructed with matte tin lead-free plating and complies with halogen-free Pb-free E3 environmental standards, supporting sustainability requirements.

The package length is 9.5 mm with a diameter of 5.3 mm, and it offers low incremental surge resistance ensuring minimal power loss during transient events. The typical response time is under 1 picosecond (ps), which guarantees rapid suppression of voltage spikes, protecting delicate electronics.

This TVS diode also boasts a long soldering thermal tolerance of 260°C for 40 seconds, suitable for modern PCB assembly processes. It is ideal for industrial electronics, power supply protection, automotive electronics not requiring automotive-specific standards, and consumer electronics requiring robust transient suppression.
