When a surge hits, it clamps at 113 V maximum while shunting 13.9 A of peak pulse current (10/1000 µs waveform). That 1500 W peak pulse rating tells you the energy it can absorb in a single shot before the junction gives up — useful for secondary protection on DC rails, relay coils, or I/O lines where the incoming spike is fast and high-energy. The three voltage thresholds define the protection window: reverse standoff at 70.1 V (the rail voltage it leaves alone), breakdown at 77.9 V minimum (where it starts conducting), and clamp at 113 V (where it holds the surge voltage). A 48 V or 60 V DC bus sits comfortably below the standoff; a 72 V nominal telecom rail is tight but still within margin if the steady-state tolerance is ±5%. ## Package and mounting — through-hole DO-201 Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE82CA A0G is a through-hole part — the leads take the mechanical strain of the surge current, and the body sits off the board for convection cooling. Bidirectional construction means a single device clamps both polarities — no need for two diodes back-to-back on an AC-coupled line or a bipolar supply rail. One channel, one DO-201 footprint, both halves of the waveform covered. ## Sourcing and compliance The part ships in Tape & Box (TB) packaging, suitable for hand-insertion or selective-wave soldering. No power line protection rating is specified, so treat it as a secondary-side transient suppressor rather than a primary mains protector.","metaTitle":"1.5KE82CA A0G TVS Diode, 1500W, 70.1V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE82CA A0G bidirectional TVS, 1500W peak pulse, 70.1V standoff, 113V clamp.
