AEC-Q101 qualification confirms the part meets automotive stress and reliability screening — junction temperature range from -55 °C to 150 °C covers under-hood and engine-bay thermal profiles. ## Clamping and breakdown window Breakdown voltage min is 108 V, reverse standoff typ 97.2 V, and maximum clamping at 9.1 A peak pulse current is 173 V. The 65.8 V gap between standoff and clamp gives the downstream converter headroom before the TVS fully conducts. Single unidirectional channel — the cathode band on the DO-214AB package marks the grounded side. No power line protection means this device is intended for signal or low-side DC rail clamping, not AC mains. ## Package and board integration DO-214AB (SMC) surface-mount package — the same footprint as standard SMC diodes. The 1500 W rating assumes a copper pad area per the datasheet layout; the junction-to-ambient thermal resistance depends on the board's copper pour under the cathode tab. The -55 °C to 150 °C operating junction range means no derating concern for reflow profiles up to 260 °C peak. ## Production status and sourcing No official second-source or pin-compatible cross-reference is listed. The base product number 1.5SMC120 covers the voltage variant family; confirm the standoff voltage matches the protected rail before committing the BOM line.","metaTitle":"1.5SMC120H TVS Diode, 1500W, AEC-Q101, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC120H automotive Zener TVS, 1500W peak pulse, 97.2V standoff, 173V clamp.
