Excellent alternative with identical package and speed, plus higher voltage and current ratings.
Finding a substitute for the BAS16X switching diode involves matching its SOD-523 package, 85V reverse voltage, and fast 4ns recovery time. Several alternatives offer similar or improved electrical characteristics.
Using a diode with slower trr (>6ns) or lower voltage (<85V) can cause circuit failure.
SOD-523 is a standard package, making physical replacement straightforward.
Direct replacement for BAS16X should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
1N914WT offers a nearly identical profile with the same recovery time and higher voltage/current ratings, making it the top choice.
The primary risk is substituting with a diode that has a slower reverse recovery time (trr), which can impact performance in high-speed switching circuits.

| Feature / factor | BAS16X | 1N914WT | BAS16XV2T1G | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOD-523 | SOD-523 | SOD-523 | SOD-523 — Identical package ensures form-fit compatibility.; BAS16XV2T1G: Identical package ensures form-fit compatibility. | |
| Voltage | 85V | 100V | 100V | 100V — Higher voltage rating provides increased design margin.; BAS16XV2T1G: Higher voltage rating provides increased design margin. | |
| Current | 155mA | 200mA | 200mA | 200mA — Higher current rating provides more operational headroom.; BAS16XV2T1G: Higher current rating provides more operational headroom. | |
| Speed | 4ns | 4ns | 6ns | 4ns / 6ns — Identical reverse recovery time (trr) ensures functional timing match.; BAS16XV2T1G: Slightly slower reverse recovery time (trr) may be acceptable but requires review for timing-critical circuits. |
Verified drop-in options for BAS16X 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.
