Product details

If you are maintaining a legacy board, qualify the part from a verified lot; if you are designing new, look at current ST Schottky families in the same TO-220FP footprint.

45 V, 15 A per diode — what the ratings tell you

The 45 V reverse voltage (Vr) sets the DC bus ceiling. The forward voltage is 570 mV maximum at 15 A per diode.

200°C junction — the thermal headroom

The maximum junction temperature is rated at 200°C. The 200 µA reverse leakage at 45 V is typical for a 45 V Schottky.

Package and mounting — TO-220FP full pack

The STPS3045CFP comes in a TO-220-3 Full Pack (TO-220FP) through-hole package. The 'Full Pack' means the back of the package is molded plastic — no exposed metal tab — so the device is fully isolated.
