Product details

The STPS30120CR is listed as Obsolete.

What this part is — dual Schottky in a TO-262AA I2PAK

The two diodes share a common cathode in a single through-hole TO-262AA I2PAK package. It is a fast-recovery type, specified at ≤500 ns, which is faster than a standard Schottky — relevant for higher-frequency rectification where switching losses matter.

Key ratings — what they mean for a replacement search

The 120 V reverse voltage and 15 A per-diode current rating set the operating envelope. The forward voltage drop is 920 mV maximum at 15 A, and reverse leakage is 15 µA at 120 V. Junction temperature maxes out at 175 °C — that is a high-temperature Schottky, useful in hot environments like a PFC stage or a DC-DC converter output. When looking for a drop-in substitute, the common-cathode configuration in a TO-262AA footprint is the hard constraint; the 15 A and 120 V are the electrical floor.

Frequently asked questions

What is the replacement for STPS30120CR?

The evidence does not list an official STMicroelectronics successor for this exact order code. A replacement must match the dual common-cathode configuration, 120 V reverse voltage, 15 A per diode, and the TO-262AA I2PAK footprint. Without an official cross-reference, the best approach is to search for a Schottky rectifier with those same ratings — the 120 V and 15 A per diode are the electrical floor; the common-cathode pair and through-hole I2PAK package are the mechanical constraint.
