The SMC footprint provides adequate copper area for heat sinking during the 10/1000µs pulse; the junction-to-ambient thermal impedance determines how many pulses can be absorbed before derating is needed. It is a single unidirectional channel device — the cathode band identifies the anode-to-cathode orientation. ## Sourcing and compliance posture The AEC-Q101 qualification is the key compliance document for automotive buyers — it covers the PPAP (Production Part Approval Process) requirements that tier-1 suppliers demand. Telecom applications are also listed, reflecting the 1500W pulse capability that suits central-office and base-station power feeds.","metaTitle":"1.5SMC180H TVS Diode, 1500W, AEC-Q101, DO-214AB","metaDescription":"1.5SMC180H Zener TVS diode, 1500W peak pulse, 146V standoff, AEC-Q101 automotive grade.
