The reverse standoff voltage is 23.1 V typical, with a minimum breakdown of 25.7 V. This gives a 2.6 V guard band above a nominal 24 V rail before the diode starts conducting — enough to hold off steady-state ripple without nuisance clamping. Single bidirectional channel means a single device protects a signal pair or a floating line against both positive and negative transients, reducing component count on the board compared to back-to-back unidirectional parts. ## Through-hole axial package, active production Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE27CAHA0G mounts through-hole. The large body and thick leads handle the thermal pulse of a 1500 W surge without exceeding the junction temperature limit — the lead frame acts as a heat sink during the event.","metaTitle":"1.5KE27CAHA0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"1.5KE27CAHA0G bidirectional TVS diode, 1500W peak pulse, 23.1V standoff, AEC-Q101 automotive grade.
