The large body and lead cross-section handle the thermal pulse of a 1500 W, 10/1000 µs event without the junction temperature exceeding the 175°C limit. The axial leads mount into plated through-holes on the PCB; the lead bend radius should follow the manufacturer's recommendation to avoid stress cracking the glass passivation at the lead exit. ## Sourcing and lifecycle posture The base product number 1.5KE11 covers the family; the full suffix HE3_A/D specifies the AEC-Q101 qualified, bidirectional, tape-and-box variant.","metaTitle":"Vishay 1.5KE11CAHE3_A/D TVS, 1500W, 9.4V, Bidirectional","metaDescription":"Vishay 1.5KE11CAHE3_A/D bidirectional TVS diode, AEC-Q101, 1500W peak pulse, 9.4V standoff, DO-201AD.
