AO3413 is a P-channel SOT-23 option only for lower-voltage BSS84 applications.
BSS84 is a -60 V P-channel SOT-23 MOSFET. This batch has no verified drop-in replacement; lower-voltage options need FAE review.
VDS rating is below BSS84.
SOT-23 matches, pinout is missing.
Discrete FET, no firmware.
One kept option is NRND.
No verified pin-compatible BSS84 replacement was found in this set.
Look for an active -60 V P-channel SOT-23 MOSFET with confirmed G-D-S pinout.
Most MOSFET candidates have only -20 V or -30 V VDS ratings.

| Feature / factor | BSS84 | AO3413 | AO3409 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOT-23 | SOT-23 | SOT-23 | SOT-23 — same package name; AO3409: same package name | |
| Pinout | 3-pin | 3-pin | 3-pin | 3-pin — pin functions not shown; AO3409: pin functions not shown | |
| Voltage | -60 V | -20 V | -30 V | -20 V / -30 V — not a 60 V part; AO3409: half VDS rating | |
| Current | -0.17 A | -3 A | -2.6 A | -3 A / -2.6 A — higher ID rating; AO3409: higher ID rating | |
| Lifecycle | Active | Active | NRND | Active / NRND — active; AO3409: not for new designs |
No verified direct alternative was found here. AO3413 is only a low-voltage candidate after review.
