For a 102V bus, that clamping margin is about 60% above the rail, typical for a 1500W-class part. Bidirectional means a single DO-214AB package clamps both polarities — no need for a series diode or two unidirectional parts in anti-series. That saves board area and BOM count on AC-coupled or floating lines. The full operating temperature range is -55°C to 150°C junction, covering the automotive extended-temperature band. At the hot end, leakage current rises but the clamping voltage stays within the datasheet limits — no derating curve needed for ambient up to 125°C. DO-214AB (SMC) footprint, surface-mount. The package is the same as standard SMC diodes — the copper pad area under the cathode tab sets the thermal resistance for the 1500W pulse. A 1 oz copper pour of at least 30 mm² on the top layer keeps the junction temperature rise within the pulse rating. Supplied in Tape & Reel — compatible with automated pick-and-place. The bidirectional marking is symmetric, so orientation is not critical for placement, but the cathode band (if present) is for unidirectional variants; this part clamps both ways. ## Sourcing and compliance AEC-Q101 qualification means the manufacturer provides PPAP documentation and traceability data on request — useful for automotive or high-reliability BOMs that require lot traceability.","metaTitle":"1.5SMC120CAH TVS Diode, 1500W Bidirectional, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC120CAH bidirectional TVS, 1500W peak pulse, 102V standoff, AEC-Q101 automotive grade.
