The junction temperature range of -55 to 175 °C covers under-hood ambient plus self-heating during the pulse — derate the peak power above 25 °C per the TransZorb application note. Through-hole DO-201AA / DO-27 axial package — the leads are 0.96 mm diameter tin-plated copper. The body length is 9.1 mm; the anode end is marked with a band. This footprint is legacy; a board designed for surface-mount TVS arrays (SMC, SMB) will not accept this package without a through-hole adapter or a board spin. The 1.5KE170HE3/54 is obsolete — Vishay no longer manufactures it.","metaTitle":"1.5KE170HE3/54 Vishay TVS, 1500W, 138V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE170HE3/54 Zener TVS diode, 1500W peak pulse, 138V standoff, AEC-Q101, obsolete.
