Breakdown starts at 13.5V minimum, so the rail has about 1.4V of headroom before the diode begins to avalanche. At 22V clamping maximum, the TVS limits the transient to a voltage that downstream components rated for 25V or higher can survive. The 68.2A peak pulse current at the 10/1000µs waveform defines the surge energy the part absorbs — a 1500W peak pulse rating that covers most industrial and telecom surge profiles. ## DO-201AA axial package — board-fit note The leads are tin-plated copper; the body is molded epoxy. Through-hole mounting suits point-to-point wiring, terminal blocks, or PCB layouts where surface-mount reflow is not available. The Tape & Box (TB) packaging option (/73 suffix) ships the diodes in ammo-pack format for automated insertion — common for high-volume through-hole assembly lines.","metaTitle":"1.5KE15C-E3/73 Vishay TransZorb TVS, 1500W, 22V Clamp","metaDescription":"Obsolete Vishay 1.5KE15C-E3/73 bidirectional TVS, 1500W peak pulse, 22V clamping, DO-201AA.
