Product details

The STPS30L120CFP from STMicroelectronics is a dual Schottky rectifier rated for 120 V reverse voltage and 15 A average forward current per diode, configured as a common-cathode pair in a single TO-220 Full Pack (TO-220FP) package. The 880 mV forward drop at 15 A keeps conduction losses manageable in output rectification stages for switch-mode power supplies, battery chargers, and DC-DC converters. The fully isolated TO-220FP tab eliminates the need for an insulating washer and thermal compound against the heatsink — a time-saver in assembly and a reliability win in high-vibration environments.

Common-cathode pair — circuit topology fit

The common-cathode configuration ties the cathodes of both diodes together internally, with the two anodes brought out as separate pins.

Frequently asked questions

What is a suitable replacement for STPS30L120CFP?

STMicroelectronics has not published an official successor for the STPS30L120CFP. For a new design, look for a currently-active 120 V, 15 A dual Schottky in a TO-220 Full Pack or TO-220FP package from ST or another major manufacturer. The common-cathode configuration and fully isolated tab are the two critical selection criteria. Electrical and thermal verification against your specific operating conditions is required before substituting.

Where can I buy STPS30L120CFP available via RFQ confirmation?

The STPS30L120CFP is obsolete and not stocked in regular distribution channels.
