The reverse standoff voltage is 24.3 V, so the diode stays out of the circuit below that rail voltage and only starts conducting when the transient pushes past it. This is a unidirectional device — one channel, cathode band goes toward the rail you are protecting. Graded Automotive and qualified to AEC-Q101, the 1.5KE30H is screened for the reliability stresses an under-hood or chassis-mounted ECU sees — temperature cycling, high-temperature reverse bias, and ESD robustness. The operating junction temperature range spans -55°C to 175°C, covering the full automotive temperature envelope with margin for self-heating during the pulse. ## Package and rework considerations Housed in a DO-201AA (DO-27) axial-lead package, with the supplier device package designated DO-201. The through-hole body is straightforward to hand-solder or wave-solder — the axial leads give good thermal relief during rework, and the cathode band is clearly marked on the body so orientation is unambiguous. No moisture sensitivity level to track; it lives on the shelf as long as the leads stay clean.","metaTitle":"TSC 1.5KE30H Zener TVS, 1500W, DO-201, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE30H automotive Zener TVS diode, 1500W peak pulse, 24.3V standoff, 43.5V clamp.
