Product details

The 1.5KE220A-B: Rated for 1500W of peak pulse power (1.5kW) under the 10/1000µs exponential waveform — this is the energy-handling capacity that determines whether the TVS survives a transient without failing short. The DO-201AA axial-leaded through-hole package (also known as DO-27) handles the heat dissipation; mounting is through-hole, so the leads carry the surge current into the PCB copper.

Temperature range and general-purpose use

The device is classified for General Purpose applications and does not include power line protection — it is intended for signal and DC rail clamping, not AC mains.
