That 22.5V ceiling is the voltage the downstream circuit sees during the surge — a 12V-rated IC with 25V abs-max survives this, but a 5V logic rail would need a secondary clamp. The -55°C to 150°C junction temperature range covers both cold-start automotive and hot industrial enclosures. Derating the peak pulse power above 25°C follows the standard TVS derating curve — at 125°C ambient the effective power handling drops to roughly 75% of the 1500W rating. ## DO-201 axial package and board integration The DO-201AA (DO-27) axial-lead package is the standard through-hole TVS footprint. The 0.042-inch (1.07mm) lead diameter fits standard 0.040-inch PCB holes; the body length is about 0.375 inches (9.5mm). Bend the leads at a right angle for vertical mounting or leave straight for horizontal lay-flat on the board. The single unidirectional channel protects one signal line or one DC rail. For bidirectional or AC-line clamping, use the 'B' suffix variant of the same 1.5KE series — the 1.5KE16A/B order code as listed covers both unidirectional (A) and bidirectional (B) options in one part number. No minimum order threshold beyond the standard reel or bulk pack quantity.","metaTitle":"YAGEO 1.5KE16A/B TVS Diode, 1500W, 13.6V Standoff, DO-201","metaDescription":"YAGEO 1.5KE16A/B Zener TVS diode, 1500W peak pulse power, 13.6V reverse standoff, clamps at 22.5V.
