1500 W peak pulse, 17.1 V standoff — TVS for 12 V / 15 V rail clamping
The 1.5KE20A-TP: Breakdown occurs at a minimum of 19 V, so the diode stays off during normal rail ripple and only conducts when a transient pushes the line above that threshold. The single-channel unidirectional construction is polarity-specific — cathode band marks the grounded side.
DO-201AE axial — through-hole mounting and thermal path
Housed in a DO-201AE axial leaded package, the 1.5KE20A-TP is a through-hole part. The axial body solders into a PCB or point-to-point wiring; the lead length and copper pad area under the body set the junction-to-ambient thermal resistance, which governs how much average power it can dissipate between transients. Operating temperature range spans -55°C to 175°C (TJ), covering industrial and some automotive under-hood environments. The wide junction temperature window means the leakage current at 17.1 V reverse standoff stays manageable across the full range, though it rises exponentially near the upper limit.
Active production — sourcing for BOM fill
Micro Commercial Co lists the 1.5KE20A-TP as Active. The part is available in Tape & Reel (TR) and Cut Tape (CT) options, which suits both high-volume pick-and-place and prototype kitting. The base product number is 1.5KE20, so the -TP suffix denotes the tape-and-reel packaging variant.
