The junction temperature range spans -55°C to 175°C, covering the full industrial and automotive ambient envelope with margin for self-heating during repetitive surge events. Power line protection is not listed as a feature — this is a general-purpose transient suppressor for signal and low-power DC rails, not a primary AC mains protector. The bulk packaging suits manual or wave-solder assembly in lower-volume production runs. ## Active production and sourcing posture The axial DO-201 footprint is a common industry standard — if a second-source hedge is needed, parametric equivalents from other manufacturers in the same package are straightforward to qualify.","metaTitle":"1.5KE9.1A B0G TVS Diode, 1.5kW, 7.78V Standoff","metaDescription":"Taiwan Semiconductor 1.5KE9.1A B0G unidirectional Zener TVS, 1500W peak pulse power, 7.78V reverse standoff, 13.4V clamp.
