Each diode is rated for 120V reverse voltage and delivers fast recovery switching — ≤500ns at currents above 200mA. This configuration is typical for center-tapped secondary rectification in switch-mode power supplies, where the common cathode connects to the output rail and the two anodes take the transformer secondary windings. ## Forward drop and leakage at the junction limit Maximum forward voltage is 790 mV at 20 A, and reverse leakage is 370 µA at 120 V. The junction temperature ceiling is 150°C.","metaTitle":"STPS40M120CR Schottky Diode, 120V 20A Dual Common Cathode","metaDescription":"STPS40M120CR fast recovery Schottky rectifier, 120V 20A per diode, TO-262 I2PAK.
