With a 52V maximum clamping voltage at 28.8A peak pulse current (10/1000µs waveform), it holds a 29.1V reverse standoff — meaning a 24V nominal rail sees protection up to the clamp threshold before the diode conducts hard. ## What the ratings mean for the BOM line The 32.4V minimum breakdown voltage and 29.1V reverse standoff define the operating window: a 24V battery bus or 28V regulated rail stays below the standoff in normal conditions, and the diode starts clamping above 32.4V, protecting downstream electronics from alternator load-dump or relay kickback. The DO-201AA axial package is a through-hole form factor that handles the 1500W pulse without board delamination — the lead bend and body length match standard 0.4-inch pitch layouts, so it drops into existing TVS footprints without a board spin. Rated for continuous junction temperature from -55°C to 175°C, this diode survives under-hood thermal cycling and high-side drive self-heating — the 175°C ceiling is the same as the AEC-Q101 Grade 0 limit, giving margin in a 105°C ambient engine compartment. ## Obsolete — sourcing through independent channels Available through independent surplus and excess inventory channels. Lot traceability and date codes are confirmed at RFQ; quantities are lot-specific and quoted per the BOM line.","metaTitle":"Vishay 1.5KE36HE3/73 TVS Diode, 1500W, 52V Clamp, DO-201AA","metaDescription":"Vishay 1.5KE36HE3/73 automotive AEC-Q101 TVS zener diode, 1500W peak pulse, 52V clamping, DO-201AA axial.
