The clamping triad is what drives the selection decision: 77.8V reverse standoff is the off-state working voltage the line sits at normally. Breakdown kicks in at 86.5V minimum — above that the Zener avalanche region takes over, and at 12.6A peak pulse the clamping voltage tops out at 125V. That 125V ceiling is what the downstream circuit must survive; the 77.8V standoff rating confirms the part is appropriate for 12V battery systems that can float to higher potentials under transient conditions. ## AEC-Q101 grade and thermal margins for under-hood deployment AEC-Q101 qualification is the automotive discrete-semiconductor stress screen — it certifies the part passed temperature cycling, humidity bias, and surge testing at levels a commercial-grade TVS is not required to survive. The 150°C TJ maximum also sets the board-level derating rule: any thermal pad or copper pad under the DO-214AB package that pushes junction temperature above 150°C at peak pulse current accelerates failure. The 125V clamping voltage at 12.6A represents a real power dissipation event — the thermal path from junction to ambient must be validated for the worst-case pulse width in the application. ## DO-214AB SMC package and automotive SM assembly fit The single unidirectional channel means this part handles one polarity only — it clamps positive transients and presents a reverse-biased Zener in the normal direction. If bidirectional protection is required a different part type is needed; the 1.5SMC91AHM6G does not provide power-line protection and is not intended for AC line roles.","metaTitle":"Taiwan Semiconductor 1.5SMC91AHM6G, 1500W Zener TVS Diode","metaDescription":"AEC-Q101 Zener TVS diode, 77.8V standoff, 125V clamping, 12.6A peak pulse, DO-214AB SMC.
