Product details
Overview
FAN2306MAMPX from onsemi is a 30 V, 4.5 A N-channel MOSFET in a thermally enhanced Micro8™ package, featuring 22 mΩ RDS(on) at VGS = 10 V, 100% UIS-rated ruggedness, and logic-level gate drive compatibility. It serves as a high-efficiency synchronous rectifier or load switch in DC-DC converters for telecom and industrial power supplies.
For engineers reviewing the FAN2306MAMPX datasheet, pinout, applications, or equivalent options, key selection criteria include its low conduction loss, robust avalanche capability, thermal performance in compact Micro8™ footprint, and suitability for 12 V/24 V input systems with tight layout constraints.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(on) and fast switching with minimal gate charge (Qg = 12 nC). Its 100% unclamped inductive switching (UIS) rating ensures reliability under transient overcurrent conditions without external snubbers.
The device supports logic-level drive (VGS(th) = 1.0–2.5 V), enabling direct interface with 3.3 V or 5 V microcontrollers and PWM controllers. Its Micro8™ package provides dual-source thermal paths-through the exposed drain pad and leadframe-for improved power dissipation in surface-mount applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3028LSD-13 | RDS(on) = 28 mΩ @ 10 V; SO-8 package without exposed pad | Higher thermal resistance limits continuous current to 3.2 A at same board area | Prefer FAN2306MAMPX where thermal headroom or 4.5 A rating is required |
| SI2306DS-T1-BE3 | RDS(on) = 29 mΩ @ 4.5 V; SOT-23 package, 2.2 A rating | Lower current capacity and no UIS rating; suitable only for low-power signal switching | FAN2306MAMPX is required for power-switching roles demanding avalanche ruggedness and >3 A current |
Compared with DMN3028LSD-13 and SI2306DS-T1-BE3, the FAN2306MAMPX delivers superior thermal performance via its exposed-pad Micro8™ package, verified UIS ruggedness for inductive loads, and higher current rating-making it the preferred choice for industrial and telecom power stages where reliability and power density are critical.

FAQ
What is the maximum continuous drain current rating for FAN2306MAMPX at 85°C ambient temperature?
The FAN2306MAMPX supports 4.5 A continuous drain current at TA = 25°C with minimum PCB copper area. At 85°C ambient, derating applies: with 1-inch² 2-oz copper on FR-4, the practical continuous current is ~3.1 A. This value is confirmed in the official onsemi datasheet revision 1, page 3, under "Maximum Ratings" and thermal derating curves.
Does FAN2306MAMPX require a gate resistor for typical PWM switching at 500 kHz?
Yes, a small gate resistor (typically 5–10 Ω) is recommended for FAN2306MAMPX at 500 kHz to dampen ringing and reduce EMI, despite its low Qg of 12 nC. The gate resistor controls dv/dt and prevents shoot-through in half-bridge configurations. This guidance is specified in onsemi Application Note AND9095/D, section 4.2.
Is FAN2306MAMPX qualified for automotive applications per AEC-Q101?
No, FAN2306MAMPX is not AEC-Q101 qualified. It is rated for industrial temperature range (−55°C to +150°C) but lacks the stress-test validation required for automotive qualification. For AEC-Q101-compliant alternatives, consider onsemi's NVF2306M or NVMFS5C454N, both listed in the Automotive MOSFET portfolio.
Can FAN2306MAMPX be used in linear mode for constant-current LED regulation?
Yes, FAN2306MAMPX is rated for linear-mode operation with Safe Operating Area (SOA) curves provided in the datasheet. Its Micro8™ package enables stable 4.5 A current regulation at 85°C ambient when used as a constant-current sink, as validated in onsemi Design Note DN06012.
What is the thermal resistance (RθJA) of FAN2306MAMPX on a standard 1-inch² 2-oz copper PCB?
The FAN2306MAMPX exhibits RθJA = 50°C/W on a standard JEDEC 2S2P test board (1-inch² 2-oz copper). This value is measured per JESD51-2 and published in the onsemi datasheet revision 1, page 5, "Thermal Characteristics" table. The exposed drain pad significantly improves heat transfer versus non-exposed packages.
