AEC-Q101 Grade 0 qualification means the part has passed the full reliability stress suite for automotive-grade discrete semiconductors. ## Clamping voltage and peak current — the protection window Breakdown voltage starts at 19V minimum, with a 17.1V standoff voltage below which the diode draws negligible leakage. For sustained repetitive transients, the average power dissipation must stay within the package's thermal limits. ## Through-hole axial package for board-level integration Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE20AHE3_A/D mounts through-hole. The lead spacing and body diameter match standard 0.100-inch pitch PCB layouts. The axial form factor allows either vertical or horizontal mounting depending on board clearance. The Tape & Box (TB) packaging option suits automated insertion equipment. The 1.5KE base product number covers the full voltage range; the A suffix indicates 5% tolerance on breakdown voltage. ## Active production — no last-time-buy pressure Vishay lists the 1.5KE20AHE3_A/D as Active in production. No official successor or pin-compatible alternative is listed — the 1.5KE20AHE3_A/D is the current production variant for this voltage and power class. For volume requirements, pricing and lead time are confirmed at quote against the BOM quantity.","metaTitle":"1.5KE20AHE3_A/D Vishay TVS, 1500W, 17.1V Standoff, AEC-Q101","metaDescription":"Vishay 1.5KE20AHE3_A/D automotive TVS diode, 1500W peak pulse, 17.1V standoff, AEC-Q101 qualified.
