A 600 V SiC Schottky would need derating headroom that eats into the margin; at 1200 V you get a full 400 V safety band over a nominal 800 V rail, covering transients from grid surges and motor regeneration without avalanche stress. Forward voltage is 1.5 V maximum at 20 A. ## 20 A in a TO-220AC — thermal reality 20 A average rectified current through a TO-220AC package is achievable only with adequate heatsinking.","metaTitle":"STMicroelectronics STPSC20H12D SiC Schottky, 1200 V, 20 A","metaDescription":"Silicon Carbide Schottky diode, 1200 V, 20 A average, zero reverse recovery time.
