The junction temperature range spans -55°C to 175°C, covering industrial and automotive underhood thermal profiles where the ambient sees sustained high heat. The base product number is 1.5KE7V5; the -B suffix indicates Bulk packaging. No power line protection feature is implemented — this is a pure transient suppressor, not a crowbar or foldback device. ## Clamping voltage and breakdown margin Minimum breakdown voltage is 7.13V, giving a 0.73V guard band above the 6.4V standoff. The 11.3V clamp at 132A Ipp means a 5V or 3.3V rail sees the clamp voltage directly — a downstream regulator or load must survive the full clamp transient, not just the standoff level.","metaTitle":"Diodes Inc 1.5KE7V5CA-B TVS, 1500W, 6.4V Standoff, DO-201","metaDescription":"Obsolete Diodes Inc 1.5KE7V5CA-B bidirectional TVS diode, 1500W peak pulse power, 6.4V standoff, DO-201 axial.
