Its 113V maximum clamping voltage at 13.5A peak pulse current (10/1000µs waveform) means a 72V battery bus or 70V telecom supply sees the surge clipped before it reaches downstream silicon. ## Peak pulse power and thermal margin Breakdown voltage starts at 77.9V minimum, ensuring the avalanche region activates cleanly above the 70.1V reverse standoff. No power line protection feature is built in — this is a standalone transient suppressor, not a filtered or coordinated protection IC. ## Through-hole mounting and storage Housed in a DO-201AA axial-lead package (DO-27 equivalent), the 1.5KE82A mounts through-hole on a PCB or terminal block. The lead spacing suits standard 0.4-inch hole patterns. Littelfuse lists the 1.5KE82A as Active. For BOM planning, this part is not a single-source risk — the 1.5KE series is a broad, long-running TVS family with multiple distributors carrying stock.","metaTitle":"Littelfuse 1.5KE82A TVS Diode, 1500W, 70.1V Standoff","metaDescription":"Littelfuse 1.5KE82A Zener TVS diode, 1500W peak pulse power, 70.1V reverse standoff, 113V clamping.
