The 234V maximum clamp at 6.4A peak pulse (10/1000µs) sets the voltage that the protected downstream circuitry must survive — a 250V-rated MOSFET or capacitor bank has margin to this clamp. Rated peak pulse power of 1500W (10/1000µs) covers the energy of a single load-dump event on a 48V bus. The bidirectional construction (one channel) eliminates the need for two back-to-back unidirectional devices on an AC-coupled or polarity-reversal-prone line. ## Through-hole DO-201 axial package The DO-201AA / DO-27 axial leaded package (0.375-inch body length) requires a 1.0 mm (0.040-inch) diameter hole per lead on the PCB. The 1.5KE body marking matches the supplier device code; the cathode band identifies polarity, though for a bidirectional part the marking convention still applies. In a 105°C ambient underhood environment, the junction rise from self-heating during a surge must stay below 70°C to remain within the rating.","metaTitle":"1.5KE170CAHE3_A/D Vishay TVS, 1500W, 145V Bidirectional","metaDescription":"Vishay 1.5KE170CAHE3_A/D TransZorb® TVS, AEC-Q101 qualified, 1500W peak pulse, 145V standoff, bidirectional, DO-201 axial.
