The -55°C to 175°C operating junction temperature covers the full under-hood thermal profile — an ECU sitting near the engine block on a hot day still has margin before the die reaches its limit. The bidirectional configuration (single channel) protects against both positive and negative transients with one device, simplifying the BOM and saving board space compared to using two unidirectional diodes back-to-back. ## Package and board integration The base product number 1.5KE11 identifies the family and breakdown voltage; the CA suffix confirms bidirectional polarity. The HE3 suffix denotes the AEC-Q101 automotive grade with the Vishay Green (RoHS-compliant) finish.","metaTitle":"Vishay 1.5KE11CAHE3_A/C TVS Diode, 1500W, 9.4V Standoff","metaDescription":"Vishay 1.5KE11CAHE3_A/C bidirectional TVS diode, 1500W peak pulse, 9.4V standoff, AEC-Q101 automotive grade.
