The 3.8 A peak pulse current rating tells you the diode can sink that much current through the avalanche without failing short. Housed in a DO-201AA (DO-27) axial-lead package, it mounts through-hole. The 0.052-inch lead diameter fits standard 0.040-inch plated through-holes; the body length is about 0.4 inches. On a double-sided board, the leads are clinched and soldered on the bottom side — the axial form factor is still common in power supplies and automotive junction boxes where the diode sits off the board with a heat-shrink sleeve. This is a current-production part, not a discontinued line.","metaTitle":"TSC 1.5KE300CAHA0G TVS Diode, 1.5kW, 256V, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE300CAHA0G bidirectional TVS, 1500W peak pulse, 256V standoff, AEC-Q101.
