That clamp voltage is the highest voltage the protected circuitry sees during the surge — downstream components must survive at least that peak. The 1500W rating is the product of clamp voltage and peak current at the 10/1000µs test waveform — a standard automotive transient pulse. A shorter pulse (8/20µs) allows higher peak current; a longer one derates the power. ## Obsolete — sourcing through independent channels Availability and pricing are confirmed at RFQ against the BOM quantity; each lot is verified for authenticity and RoHS compliance. The DO-201AA (DO-27) axial-lead package is through-hole mount, compatible with existing PCB layouts for this footprint.","metaTitle":"Vishay 1.5KE39AHE3/51 TransZorb TVS, 1500W, 33.3V, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE39AHE3/51 1500W unidirectional TVS diode, AEC-Q101 automotive grade, 33.3V standoff, 53.9V clamp.
