The 64.1 V reverse standoff voltage is the DC rail level where the diode stays off — below that, leakage is negligible. The breakdown starts at 71.3 V minimum, so on a 48 V nominal bus with 20 % tolerance (57.6 V max), this part holds margin before it starts conducting. DO-201AA (DO-27) axial-lead package — the body is 9.1 mm long, the leads are 1.3 mm diameter tinned copper. It mounts through-hole, so the board needs a 1.2 mm drilled hole per lead; the axial form factor means the part stands off the board or lies flat depending on the bend radius. The R0G suffix on the order code indicates Tape & Reel packaging — 500 pieces per reel, suitable for auto-insertion. For hand-populated prototypes, the same die is available in bulk or ammo pack under the base number 1.5KE75A. ## Sourcing and lifecycle posture That means the factory continues to run it, and authorized distribution carries it as a standard line item. This is a unidirectional Zener TVS — one channel per package. If the BOM calls for bidirectional clamping on the same rail, the 1.5KE75CA (the 'C' suffix) is the back-to-back version; same standoff, same clamping, same footprint.","metaTitle":"1.5KE75A R0G TVS Diode, 1.5kW, 64.1V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE75A R0G Zener TVS diode, 1500W peak pulse, 64.1V standoff, 103V clamp.
