Board-level designers route the clamping path tight to the protected node so the loop inductance does not allow the voltage spike to overshoot before the TVS responds. ## Operating temperature and what it permits The junction temperature ceiling of 150 °C with a low-end of −50 °C gives the part headroom for automotive under-hood environments and industrial enclosures that run hot. The SMC/DO-214AB package relies on the board copper pad for thermal sinking — the datasheet thermal impedance curve determines how much copper island the layout needs to hold the junction below 150 °C at the expected surge duty. Bidirectional operation (, single channel) means it clamps both polarities without a polarity mark — suitable for AC rails, RS-485 bus lines, and any node where the transient can swing both ways. For a unidirectional protection path the unipolar series would be the right fit. Diotec Semiconductor lists the 1.5SMCJ13CA as Active.","metaTitle":"1.5SMCJ13CA TVS Diode, 21.5V Clamping, 1500W","metaDescription":"Diotec 1.5SMCJ13CA bidirectional Zener TVS diode, 13V standoff, 21.5V max clamping @ 69.8A peak.
