The junction temperature range spans -55°C to 175°C, covering under-hood and cabin environments. ## Voltage breakdown and clamping — what the ratings mean for your rail The minimum breakdown voltage is 19.8 V, so the diode starts conducting at that level. The reverse standoff voltage of 17.8 V is the continuous DC bias the part can hold without significant leakage — a 12 V nominal rail with transients up to 17.8 V stays below the avalanche threshold. The 1500 W peak pulse rating at 10/1000 µs is a standard TVS power metric — it assumes a 1 ms pulse width. For shorter transients (e.g. 8/20 µs per IEC 61000-4-5), the part can handle significantly higher peak current; the 49 A figure at 31.9 V clamping confirms the 1500 W derating at the 1 ms pulse condition. ## Package and board-fit — DO-201AA axial Through-hole mounting suits point-to-point wiring or PCB layouts where the lead bend radius absorbs thermal expansion. The axial body is standard for 1.5 kW TVS diodes — the lead diameter and body length match the common footprint across the 1.5KE family. ## Lifecycle and supply posture The AEC-Q101 qualification and the 1.5KE series longevity make this a stable line item for automotive and industrial power-supply protection.","metaTitle":"1.5KE22H Taiwan Semiconductor Zener TVS, 1500W, DO-201","metaDescription":"1.5KE22H Zener TVS diode, 1500W peak pulse, 17.8V standoff, AEC-Q101 automotive grade.
