Product details

30 V, 1.2 A N-channel in SOT-23 — logic-level gate, low gate charge

The drive voltage range for achieving rated Rds(on) is 4.5 V to 10 V; at 3.3 V gate drive the on-resistance will be higher than the 250 mOhm max specified at 10 V.

SOT-23 footprint, 540 mW dissipation, -55 to 150 °C junction

Supplied in the Micro3™/SOT-23 package (TO-236-3 / SC-59 / SOT-23-3), surface-mount only — the 540 mW power dissipation at 25 °C ambient is the thermal budget for the small footprint.

The part is ROHS3 compliant.

Frequently asked questions

Is IRLML2803TRPBF a logic-level MOSFET?

Yes.

What is the Rds(on) of IRLML2803TRPBF at 3.3 V gate drive?

The datasheet specifies Rds(on) at 4.5 V and 10 V drive voltages. At 3.3 V gate drive the on-resistance will be higher than the 250 mOhm max listed at 10 V — the exact value depends on the Vgs vs Rds(on) curve in the datasheet.
