That's the figure to plug into your thermal budget: at full rated current, each die dissipates about 16.8 W before any derating. The 1.5 mA reverse leakage at 45 V is typical for a 45 V Schottky at room temperature — expect it to climb with junction temperature, so keep the heatsink sized to stay well below the 150°C max junction temperature.","metaTitle":"STPS61L45CW Schottky Diode Array","metaDescription":"STPS61L45CW dual Schottky rectifier: 45V Vr, 30A per diode, 560mV Vf at 30A, common cathode in TO-247-3.
