The 18A peak pulse current rating tells you the clamping voltage is achievable at that current — if your actual surge source impedance is very low, the diode will conduct hard and the clamping voltage will be the governing number, not the standoff. ## Junction thermal margin and the -55°C cold end Rated to 150°C junction temperature with a bottom-end limit of -55°C — this covers the outdoor-equipment and transportation temperature band without derating. The upper limit is set by the silicon-gate Zener structure; exceeding it on a sustained basis shifts the breakdown voltage and eventually degrades the clamping characteristic. Listed as Active by Taiwan Semiconductor Corporation. Quoted to order; availability and lead time confirmed at RFQ.","metaTitle":"Taiwan Semiconductor 1.5SMC62A R7G, 53V standoff","metaDescription":"1.5SMC62A R7G — unidirectional Zener TVS, 53V standoff, 85V clamping at 18A peak pulse.
