Best Alternatives to DMP3099L-7

Package: TO-236-3, SC-59, SOT-23-3Diodes IncorporatedMOSFETs - SingleSeries: -Package: Tape & Reel (TR); Cut Tape (CT); Digi-Reel®Technology: MOSFET (Metal Oxide)Drain to Source Voltage (Vdss): 30 VCurrent - Continuous Drain (Id) @ 25°C: 3.8A (Ta)

DMP3099L-7 is a -30V P-channel SOT23 MOSFET. Alternatives need careful VDS, pinout, and thermal review.

AI replacement insight

Electrical riskhigh

VDS, ID, RDS(on), and Qg differ.

Package riskmedium

SOT23 matches, pinout missing.

Firmware risklow

Discrete MOSFET only.

Sourcing riskmedium

One close candidate is EOL.

Can it be replaced directly?

Direct replacement for DMP3099L-7 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Start with DMP3130L-7 for same-voltage review, but note EOL and weaker ratings.

Main risk

Pinout is unverified and several candidates have lower voltage ratings.
