The 71.7A Ipp figure is the peak current the device can shunt without exceeding its thermal limit on that waveform; real-world surge duration shorter than 1000µs allows higher peak current within the same power envelope. The through-hole DO-201AA axial package handles the thermal cycling of soldered leads better than surface-mount equivalents in high-vibration settings. Power line protection is marked as 'No' — this TVS is designed for signal and low-power DC rail protection, not for AC mains or high-energy direct lightning strike suppression. For mains protection, a higher-energy MOV or gas discharge tube would be the correct class.","metaTitle":"Littelfuse 1.5KE15CA TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Littelfuse 1.5KE15CA Zener TVS diode, 1500W peak pulse power, 12.8V standoff, 21.2V clamp, bidirectional, DO-201 axial.
