Its zero reverse recovery time (0 ns trr) eliminates the switching losses that plague ultrafast silicon diodes in hard-switched topologies — no recovery charge to extract, no tail current. The 1200 V blocking voltage covers 400 VAC rectified rails (≈560 VDC) with margin for switching overshoot, and even 800 VDC bus architectures common in 3-phase industrial drives and EV charging stations. The 5 A average rating is the thermal current limit at Tc=100°C — in a continuous-conduction-mode PFC the RMS current is higher than the average, so the designer sizes the heatsink for the conduction loss at the forward voltage of 1.5 V at 5 A. The 450 pF junction capacitance at 0 V is low enough that the capacitive turn-on loss at a few hundred kHz stays manageable. ## 175°C junction — thermal headroom for tight enclosures The 175°C upper limit allows the junction to ride through overload transients without immediate derating, and it simplifies heatsink design in sealed or fanless power supplies where the ambient inside the enclosure can reach 85-100°C. The 30 µA reverse leakage at 1200 V and 25°C is typical for a 5 A SiC Schottky; at 175°C the leakage rises, but the zero-recovery characteristic keeps the switching loss near zero, so the total die temperature stays lower than an equivalent ultrafast silicon diode under the same load.","metaTitle":"ST STPSC5H12D SiC Schottky Diode, 1.2 kV, 5 A, TO-220AC","metaDescription":"STPSC5H12D SiC Schottky diode, 1200 V reverse, 5 A average rectified, zero reverse recovery (0 ns trr).

The datasheet lists reverse recovery time (trr) as 0 ns, and the speed rating is 'No Recovery Time > 500 mA (Io)' — this is the defining characteristic of a SiC Schottky diode.
