For a 24 V nominal rail, this provides margin — the diode holds off the steady-state supply and only activates on a transient. The peak pulse power derates above 25°C, so at 125°C ambient the effective power handling drops to roughly 75% of the 1500 W rating — a factor to budget in high-temperature enclosures. ## Package and board fit The DO-201AA (DO-27) axial package with through-hole mounting suits point-to-point wiring or PCB layouts that need a rugged, replaceable protection device. The DO-201 suffix in the supplier device package confirms the body and lead dimensions match the standard DO-201 footprint. Packaged in Tape & Box (TB) — the A0G suffix designates the packaging option, not a functional variant. The base product number 1.5KE24 covers the unidirectional and bidirectional versions; the CA suffix in 1.5KE24CA marks this as the bidirectional channel. ## Sourcing and compliance Rated for General Purpose applications, the device is suitable for overvoltage clamping in power supplies, industrial controls, and automotive auxiliary circuits.","metaTitle":"1.5KE24CA A0G TVS Diode, 1500W, 20.5V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE24CA A0G bidirectional Zener TVS, 1500W peak pulse power, 20.5V reverse standoff, 33.2V clamp.
