Schottky pair for high-current OR-ing and output rectification
The STPS30L60CG-TR is a dual Schottky rectifier in a common-cathode configuration, rated 60 V reverse and 15 A average forward current per diode. The fast recovery spec (≤500 ns, >200 mA) means this diode handles switching frequencies well above line-frequency rectification — suitable for 100 kHz+ SMPS output stages where Schottky's low reverse-recovery charge cuts switching losses.
60 V blocking — margin for 48 V rails
With a 60 V maximum DC reverse voltage, this diode gives about 20 % headroom on a nominal 48 V bus — enough for transients in telecom rectifiers or 48 V battery-backed supplies. The 480 µA reverse leakage at 60 V is typical for a 15 A Schottky at this voltage class; expect leakage to rise with junction temperature, so factor it into standby-loss budgets.
D2PAK footprint — thermal and layout notes
The TO-263-3 (D2PAK) package has a large exposed tab on the bottom — the common-cathode output. The two anode pins are on the outer leads; the centre pin is the cathode tab.
