The DO-214AB (SMC) package is a standard surface-mount footprint for TVS diodes in this power class, hand-solderable with reasonable care — the tab is wide enough for a fine-tip iron if you pre-tin the pad. AEC-Q101 Grade 1 qualification means it's characterized across -55°C to 150°C junction temperature, covering under-hood and industrial enclosure environments without derating surprises. ## Protection window and pulse capability The reverse standoff voltage of 102V means the diode stays high-impedance below that level — your protected circuit sees no leakage penalty during normal operation. Breakdown starts at 114V minimum, and clamping is guaranteed at 165V maximum with a 9.5A peak pulse current. That 53V window between standoff and clamp gives enough margin for a 100V nominal rail with 10-15% tolerance plus switching ripple. For shorter pulses (like 8/20µs from ESD or lightning), the peak power capability is significantly higher; the datasheet's pulse-derating curve shows the multiplier. Single unidirectional channel, so polarity matters in the layout — the cathode band goes toward the protected rail. ## Sourcing and compliance posture AEC-Q101 qualification documentation is available from Taiwan Semiconductor Corporation, covering the automotive PPAP and reliability test data.","metaTitle":"1.5SMC120AH TVS Diode, 1500W, AEC-Q101, DO-214AB","metaDescription":"1.5SMC120AH Zener TVS diode, 1500W peak pulse, 102V standoff, AEC-Q101 automotive grade, DO-214AB SMC.
