The 150 °C maximum junction temperature gives the thermal designer the headroom to verify the clamping event stays within the transient thermal impedance curve, particularly on a surface-mount pad where the PCB copper acts as the heatsink. ## Package and junction temperature for board-level layout DO-214AB (SMC) body — the standard SMCJ footprint, so it lands on the same pad pattern as any SMC bidirectional TVS in this series. The cathode bar on the package marks polarity for the unidirectional direction; for the bidirectional variant the orientation is non-critical on AC lines.","metaTitle":"Vishay 1.5SMC8.2CA-E3/57T, 7.02V Standoff TVS Diode","metaDescription":"Vishay 1.5SMC8.2CA-E3/57T bidirectional TVS diode, 1500 W peak pulse. 7.02 V standoff, 12.1 V clamping.
