Availability and pricing are confirmed at RFQ against specific date-code and quantity requirements; sealed reels with consistent date-codes are preferred over mixed-lot inventory. ## 1500 W peak pulse — what it protects The 28.2 A peak pulse current (Ipp) at the clamping voltage tells you the surge the diode can shunt without failing short. A single bidirectional channel handles positive and negative transients symmetrically, so one DO-201 axial part protects a bipolar signal line or an AC-coupled interface without needing two back-to-back unidirectional diodes. The through-hole DO-201AA package (also known as DO-27) is a standard axial-lead footprint for board-level transient suppression.","metaTitle":"Littelfuse 1.5KE39C TVS Diode, 1500W, DO-201","metaDescription":"Littelfuse 1.5KE39C bidirectional Zener TVS, 1500W peak pulse, 33.3V standoff, DO-201.
