STMicroelectronics
A 60V, 2A Schottky diode in the same SMA package, offering higher voltage and current ratings.
Find suitable replacements for the onsemi SS13, a 30V, 1A Schottky diode in an SMA package. Alternatives offer different voltage, current, and forward voltage characteristics to fit your design needs.
SMA (DO-214AC) is a highly standardized package.
Must match Schottky type. Mismatched forward voltage or recovery time can cause circuit failure.
Direct replacement for SS13 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
STPS2L60A offers an upgrade in voltage and current with minimal change in forward voltage, making it a robust choice.
The primary risk is selecting a replacement with a different diode technology (e.g., Fast Recovery instead of Schottky), which would drastically increase power loss.

| Feature / factor | SS13 | STPS2L60A | STPS2H100A | STPS2L30A | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SMA (DO-214AC) | SMA (DO-214AC) | SMA | SMA | SMA (DO-214AC) — Package is physically compatible.; STPS2H100A: Package is physically compatible.; STPS2L30A: Package is physically compatible. |
| Voltage | 30V | 60V | 100V | 30V | 60V / 100V / 30V — Provides double the voltage rating, increasing design margin.; STPS2H100A: Significantly higher voltage rating increases design margin.; STPS2L30A: Identical voltage rating offers no safety margin. |
| Current | 1.0A | 2.0A | 2.0A | 2.0A | 2.0A — Higher current rating provides more thermal headroom.; STPS2H100A: Higher current rating provides more thermal headroom.; STPS2L30A: Higher current rating provides more thermal headroom. |
| Forward Voltage | 0.5V | 0.55V | 0.65V | 0.375V | 0.55V / 0.65V / 0.375V — Slightly higher Vf may minimally increase power loss.; STPS2H100A: Higher Vf will increase power dissipation; thermal analysis recommended.; STPS2L30A: Lower Vf reduces power dissipation, improving efficiency. |
| Diode Type | Schottky | Schottky | - | - | Schottky — Same diode technology ensures similar switching behavior. |
Verified drop-in options for SS13 are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
