The clamping voltage of 21.2 V at 70.8 A ensures the protected circuit sees no more than that level during a 10/1000 µs surge event. Housed in a DO-201AA (DO-27) axial leaded package, the device is through-hole mounted. The axial leads suit point-to-point wiring on terminal strips or traditional PCB layouts where the body stands off the board for convection cooling.","metaTitle":"1.5KE15CA-E3/54 Vishay TVS Diode, 1500W, 12.8V Standoff","metaDescription":"1.5KE15CA-E3/54 Vishay TransZorb bidirectional TVS, 1500W peak pulse, 12.8V standoff, DO-201AA.
