Product details

The STPS130AFN is a 30 V, 1 A Schottky rectifier from STMicroelectronics, housed in the low-profile SMAflat package (DO-221AC). Its forward voltage drop is 550 mV at the full 1 A rated current, which keeps conduction losses manageable in low-voltage rails. The fast recovery characteristic (≤ 500 ns, > 200 mA) suits it for high-frequency switching in DC-DC converters and freewheeling diodes. The ECOPACK®2 designation confirms lead-free and RoHS compliance, a standard requirement for new designs.

Obsolete — plan your BOM line accordingly

For existing BOM lines, procurement must rely on the surplus and broker channel.

SMAflat package — footprint and thermal notes

The SMAflat (DO-221AC) package is a low-profile surface-mount variant of the standard SMA. It saves board height, which matters in compact or card-edge designs. The junction temperature rating is 150 °C, so adequate PCB copper area for heat sinking is needed when running near the 1 A average rectified current.

Frequently asked questions

What is the best replacement for STPS130AFN?

The closest pin-compatible alternative is the STPS130A, which shares the same base product number (STPS130) and electrical ratings (30 V, 1 A, Schottky) but comes in the standard SMA package (DO-214AC). The SMAflat footprint of the AFN variant is different, so a board layout change is required. For a drop-in replacement in the same SMAflat package, check the STPS130AFN's sibling STPS130AF (if still available) or consider a cross to a different manufacturer's SMAflat Schottky diode with matching 30 V, 1 A ratings.

Can I use STPS130A instead of STPS130AFN?

Yes, electrically the STPS130A is identical — same 30 V reverse voltage, 1 A forward current, and Schottky diode type. The difference is the package: STPS130A uses the standard SMA (DO-214AC), while the AFN uses the SMAflat (DO-221AC). The footprints are not the same, so a PCB layout change is needed. If you need a drop-in replacement without board changes, look for another SMAflat Schottky diode with matching ratings.

Is STPS130AFN lead-free?

Yes, the STPS130AFN is ECOPACK®2 compliant, which means it is lead-free and RoHS-compliant. No additional lead-free certification is needed for most markets.
