The 11.3V clamp at 133A means that during a 1500W pulse the protected line sees no more than 11.3V, which is within the 12V abs-max of many 5V-tolerant logic families. The 133A peak pulse current is rated at the industry-standard 10/1000µs waveform (8/20µs for ESD events yields a higher Ipp). For shorter transients like an inductive kick from a relay coil, the effective clamping voltage will be lower because the diode's dynamic resistance is small — the 11.3V figure is the worst-case ceiling at the full rated energy. ## Through-hole axial package and temperature range Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE7.5A-/73 is a through-hole part suited for point-to-point wiring or PCB mounting with 0.040-inch lead diameter holes. The tape-and-box (TB) packaging option (/73 suffix) indicates bulk or ammo-pack delivery, not reel — confirm with your distributor that the quantity and lead form match your insertion equipment. The base product number 1.5KE7.5 covers both unidirectional (A suffix) and bidirectional (CA suffix) variants; this is the unidirectional version with one protected polarity.","metaTitle":"Vishay 1.5KE7.5A-E3/73 TransZorb TVS, 1500W, 7.13V Breakdown","metaDescription":"Vishay 1.5KE7.5A-E3/73 TransZorb Zener TVS diode, 1500W peak pulse, 6.4V standoff, 11.3V clamp.
