The 92V maximum clamping voltage at 16.3A peak pulse current (10/1000µs waveform) defines the voltage the downstream circuitry must survive. For a 48V bus with a 70V load-dump clamp, this TVS catches the residual spike before it reaches the ECU. The 16.3A peak pulse current at the clamping voltage confirms the diode can shunt substantial fault energy without exceeding the junction temperature limit of 175°C. The -55°C to 175°C operating junction range covers the full automotive temperature envelope, including under-hood soak at 125°C ambient. The TransZorb construction provides low inductance for fast clamping response, critical for protecting sensitive ECUs from ISO 7637-2 pulses. ## Through-hole DO-201AA package and board integration Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE68AHE3_A/C mounts through-hole on the PCB. The axial body allows either vertical or horizontal placement, useful for dense power supply layouts where board space is constrained. The single unidirectional channel protects one rail. For bidirectional or AC-line clamping, two devices in anti-series are required — the datasheet's power line protection flag (No) confirms this part is not intended for AC mains use. ## Active production and automotive compliance The base product number 1.5KE68 covers the non-automotive variant; the AHE3 suffix denotes the AEC-Q101 qualified, RoHS-compliant version with full automotive-grade screening.","metaTitle":"Vishay 1.5KE68AHE3_A/C TVS Diode, 1500W, AEC-Q101","metaDescription":"Vishay 1.5KE68AHE3_A/C TransZorb TVS, 1500W peak pulse, 58.1V standoff, AEC-Q101 qualified.
