The breakdown voltage range starts at 37.1V min, giving a guard band before the device starts conducting. A downstream 60V-rated DC-DC converter or load-dump clamp has margin above this clamp level. Power line protection is marked as 'No' — this is a unidirectional Zener TVS, not a bidirectional or steering-diode array, so it clamps one polarity only and is intended for DC rails, not AC mains. ## Active production — sourcing posture The base product number 1.5KE39 covers the full family; the 'A' suffix denotes the tighter breakdown tolerance variant.","metaTitle":"1.5KE39AHA0G Taiwan Semi Zener TVS, 1500W, DO-201, AEC-Q101","metaDescription":"1.5KE39AHA0G Taiwan Semiconductor Zener TVS diode, 1500W peak pulse, 33.3V standoff, 53.9V clamp, AEC-Q101 automotive grade.
