The device handles a peak pulse current of 54.2 A under the 10/1000 µs test condition, which defines the energy it can absorb without failing. Operating temperature spans -65 °C to 150 °C (junction), covering the full industrial range and beyond — no derating concern for most ambient environments. Supplied in a DO-214AB (SMC) surface-mount package, the same footprint as the SMCJ suffix. The single unidirectional channel occupies minimal board area, and the Tape & Reel packaging suits automated assembly. No power line protection feature — this is a signal- or low-voltage DC rail clamp, not a mains-side device.","metaTitle":"1.5SMC20A-E3/9AT Vishay TVS, 1500W, 17.1V standoff, DO-214AB","metaDescription":"Vishay 1.5SMC20A-E3/9AT Zener TVS diode, 1500W peak pulse, 17.1V standoff, unidirectional, DO-214AB.
