The lead spacing is 8.9 mm. For a 1500 W transient, the recommended copper pad area under each lead is at least 30 mm² per side to keep the lead-to-board thermal resistance below 60°C/W. The part is supplied in Tape & Box (TB) format — 500 pieces per box on a 52 mm tape width — suitable for hand-insertion or semi-automated assembly lines. No power line protection is built in, so this TVS is intended for signal and low-power supply rail clamping only.","metaTitle":"1.5KE43AHE3_A/D Vishay TVS Diode, 1.5kW, DO-201AA","metaDescription":"Vishay 1.5KE43AHE3_A/D TransZorb TVS, 1500W peak pulse, 36.8V standoff, AEC-Q101, DO-201AA axial.
