AEC-Q101 TransZorb for 12/24 V automotive bus protection
The Vishay 1.5KE180AHE3_A/D is a 1500 W peak-pulse-power TVS diode from the Automotive TransZorb series, qualified to AEC-Q101 for under-hood and engine-bay deployment. For a 24 V truck system with a 150 V load-dump transient, this TVS catches the spike before it reaches the ECU's input capacitors.
Package and board-fit — DO-201AA axial through-hole
Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE180AHE3_A/D mounts through-hole. The axial body sits above the board — the leads are formed for either vertical or horizontal insertion depending on the PCB layout. The 1.5KE supplier device package code matches the standard Vishay footprint for this series. The wide junction temperature margin means the device can sit near a hot engine block or exhaust manifold without derating the peak-pulse power below 1500 W.
