For a 15.3 V reverse standoff rail, the protection window starts at 17.1 V breakdown — the diode stays transparent below that and only conducts when the transient exceeds the normal operating voltage. The single bidirectional channel protects a signal pair or a floating supply line in one package — no need for two back-to-back unidirectional devices. General-purpose application covers power supplies, telecom ports, and industrial I/O where the transient energy is moderate and the line impedance keeps the surge within the 1500 W envelope. ## Through-hole DO-201 package and temperature range Housed in a DO-201AA axial package with through-hole mounting, the part suits point-to-point wiring on terminal blocks or perforated boards where surface-mount reflow is not an option. The junction temperature range spans -55 °C to 175 °C, covering outdoor enclosures and engine-bay environments without derating at the high end — the 1500 W rating holds across the full temperature band. Supplied in Tape & Box (TB) format for hand-insertion or axial-lead forming machines. The base product number 1.5KE18 is shared across the family; the full suffix A0G specifies the bidirectional polarity and the packaging variant.","metaTitle":"Taiwan Semiconductor 1.5KE18CA A0G TVS, 1500W","metaDescription":"1.5KE18CA A0G bidirectional Zener TVS, 1500W peak pulse, 15.3V standoff, 60A Ipp. Active production, DO-201 package.
