Breakdown occurs at 17.1 V minimum, so the diode starts conducting before the clamp voltage is reached, shunting the surge current to ground. The bidirectional channel means you can use it across a differential pair or a single supply rail without worrying about polarity. ## Through-hole axial package and temperature range Housed in a DO-201AA (DO-27) axial-lead package, this TVS is a through-hole part — it solders into a board with two leads, one on each end. The package is rated for an operating junction temperature from -55°C to 175°C, covering automotive under-hood and industrial environments. The 1.5KE18CAHE3_A/C is supplied in tape and reel (TR) packaging, which is the standard for automated insertion during board assembly. ## Automotive qualification and compliance It is intended for use in automotive electronics where a single transient failure cannot be tolerated.","metaTitle":"1.5KE18CAHE3_A/C Vishay TVS, 1500W, 15.3V Standoff","metaDescription":"Vishay 1.5KE18CAHE3_A/C bidirectional TVS, 1500W peak pulse, 15.3V standoff, 25.2V clamp.
