Product details

Dual Schottky rectifier for OR-ing and output stages

The forward voltage drops to 490 mV at 15 A, which keeps conduction losses manageable in low-voltage power paths. The fast recovery spec (≤500 ns) qualifies it for switching frequencies above 200 mA where a standard PN diode would lag.

Housed in a D2PAK (TO-263-3) surface-mount package with the tab as the common cathode connection.

STMicroelectronics lists the STPS3030CG as obsolete. No official successor is recorded in the lifecycle data.

Frequently asked questions

Is STPS3030CG obsolete?

Yes, STMicroelectronics has marked the STPS3030CG as obsolete. There is no official replacement part number listed.

What is the Vf of STPS3030CG?

The maximum forward voltage is 490 mV at 15 A per diode. This low Vf is typical for a 30 V Schottky and helps minimise conduction loss in OR-ing and output rectifier stages.

What is the difference between STPS3030CG and STPS3030CT?

The STPS3030CG and STPS3030CT share the same 30 V, 15 A per diode Schottky die and common cathode configuration. The difference is the package: the CG variant is surface-mount D2PAK (TO-263), while the CT variant is through-hole TO-220. The electrical specs are identical, so the choice is purely a board-level assembly decision.

Can I use STPS3030CG for high-frequency switching?

The fast recovery time is specified as ≤500 ns at currents above 200 mA. This is fast enough for many 50–100 kHz switching power supplies and OR-ing diodes, but not for high-frequency converters in the MHz range. For those, look at SiC or ultra-fast recovery diodes with lower trr.
