Product details

Obsolete — sourcing the STPS10150CG today

ST lists the STPS10150CG as obsolete.

Each diode in the common-cathode pair is rated for 5 A average rectified current. The 150 V reverse voltage covers 48 V bus rails, 72 V telecom supplies, and 100 V intermediate buses with derating margin. Forward drop is 920 mV at 5 A — typical for a 150 V Schottky in this current class; expect about 4.6 W conduction loss per diode at full load, so the D2PAK's exposed pad needs a decent copper pour and via stitch to keep the junction below the 175 °C max.

D2PAK (TO-263) is a surface-mount package with a large exposed tab. It reflows well with a standard lead-free profile, but the thermal mass means the hot-air station needs a higher preheat than a small-signal SOIC — 150 °C bottom preheat is a good starting point.

Frequently asked questions

What is the equivalent or replacement for STPS10150CG?

ST has not published a direct pin-compatible successor for the STPS10150CG in the same D2PAK common-cathode configuration. For a replacement, look at the STPS10H100CG (100 V) or STPS20150CG (20 A, 150 V) if the current rating fits, but verify the footprint and pinout against your layout. In a pinch, a pair of discrete 150 V 5 A Schottkys in DPAK or D2PAK can be wired as a common-cathode pair if board space allows.
