It clamps transients on a 58.1 V nominal rail — the reverse standoff voltage — and breaks down at a minimum of 64.6 V, limiting the let-through to 92 V at the 16.5 A peak pulse current (10/1000 µs waveform). Rated for continuous junction temperatures from -55 °C to 175 °C, it handles sustained high ambient or self-heating in crowded boards without derating the pulse capability. ## Active production, no second-source on record No official cross-reference or pin-compatible second-source is listed for this order code. The 1.5KE series is a standard JEDEC DO-201 footprint, so parametric equivalents from other manufacturers exist, but a direct drop-in replacement requires verifying the breakdown and clamping voltages against the BOM. ## Sourcing and compliance The part is supplied in bulk packaging (not tape-and-reel) — store the DO-201 axial devices in anti-static tubes or bags; no moisture sensitivity level (MSL) applies to this through-hole package.","metaTitle":"1.5KE68CA-TB Littelfuse TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5KE68CA-TB 1500W bidirectional TVS diode, 58.1V standoff, 92V clamp, DO-201 axial.
