The reverse leakage at 45 V is 100 µA — expect that to climb with temperature, but the 175°C ceiling keeps the die safe in a 100°C ambient with forced air. ## Active production, ROHS3 — no compliance surprises ROHS3 compliant — no exemptions to track for EU or global BOMs. The standard TO-220AC through-hole package is a drop-in for existing layouts using the same footprint.","metaTitle":"STPS1045D Schottky Diode, 45V 10A TO-220AC","metaDescription":"STPS1045D Schottky rectifier: 45V reverse, 10A average, 600mV Vf at 10A, 175°C Tj max.
