Product details

Overview

AOD2N100 from Alpha & Omega Semiconductor is a 100 V, 2.5 A N-channel enhancement-mode MOSFET in TO-252 (DPAK) package, featuring 2.4 Ω R_DS(on) at V_GS = 10 V, 100% UIS-rated, and designed for DC-DC converters, load switches, and motor control in industrial power supplies.

For engineers reviewing the AOD2N100 datasheet, pinout, applications, or equivalent options, key selection criteria include its 100 V V_DSS, 2.5 A I_D continuous rating, 2.4 Ω on-resistance, TO-252 thermal performance, and avalanche ruggedness for unclamped inductive switching reliability.

Technical Context

The AOD2N100 uses planar trench-gate silicon technology optimized for low gate charge (Q_g = 7.5 nC) and fast switching with t_on/t_off of 12 ns/28 ns. It operates with gate threshold voltage V_GS(th) between 2.0 V and 4.0 V and supports standard logic-level drive.

Its SOA is defined up to T_C = 25 °C with 100% rated avalanche energy (E_AS = 125 mJ), and it meets JEDEC TO-252 (AA) mechanical specifications with copper leadframe and matte tin plating for solderability and thermal conduction.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	100 V - maximum drain-source blocking voltage under continuous DC operation
I_D (continuous)	2.5 A at T_C = 25 °C - usable current capacity with heatsink or PCB copper area
R_DS(on)	2.4 Ω @ V_GS = 10 V - conduction loss determines efficiency in high-side switch applications
Q_g	7.5 nC - total gate charge impacts driver sizing and switching loss in PWM circuits
E_AS	125 mJ - single-pulse avalanche energy rating confirms robustness in inductive load switching
T_J max	150 °C - maximum junction temperature defines thermal derating envelope for reliability

Pinout & Package

Package: TO-252 (DPAK), JEDEC standard outline PO-00009, with exposed drain pad for thermal dissipation and mechanical mounting via Pin 2 (Drain). Body dimensions: 6.60 mm × 6.25 mm × 2.286 mm (L × W × A).

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control input	Receives gate drive signal; requires ≥10 V for full enhancement and minimal R_DS(on)
2 (Drain)	High-side power terminal	Connected to load or supply rail; electrically tied to exposed metal tab for thermal path
3 (Source)	Reference return	Serves as common reference for gate drive and current sensing; ties to ground or low-side switch node

Key Features

Feature	Design Value

TO-252 thermal resistance (R_θJC = 50 °C/W)	Enables >1.5 W power dissipation with minimal heatsinking on 1-in² 2-oz copper
V_GS(th) range (2.0–4.0 V)	Ensures turn-on compatibility with 3.3 V and 5 V microcontroller GPIOs without level-shifting

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP2N100	R_DS(on) = 3.0 Ω @ 10 V; Q_g = 9.5 nC; same TO-220 package	Higher conduction loss and slower switching; requires larger heatsink at 2.5 A	Prefer AOD2N100 for space-constrained PCBs needing lower R_DS(on) and TO-252 footprint
IRF640NPBF	V_DSS = 200 V; R_DS(on) = 0.18 Ω; TO-220; higher cost and larger footprint	Over-specified voltage rating increases cost and board area; not optimized for 12–24 V systems	Choose AOD2N100 when 100 V rating and TO-252 thermal profile match system requirements

Compared with STP2N100 and IRF640NPBF, the AOD2N100 delivers optimal balance of 100 V rating, 2.4 Ω on-resistance, and TO-252 thermal efficiency-making it preferred for compact industrial and automotive power switches where board area and conduction loss are critical.

FAQ

What is the maximum continuous drain current rating for AOD2N100?

The AOD2N100 has a maximum continuous drain current I_D of 2.5 A at case temperature T_C = 25 °C. Derating is required above this temperature per the datasheet SOA curve; at T_C = 100 °C, the usable I_D drops to approximately 1.4 A. This rating assumes proper PCB copper area for heat spreading and is validated under JEDEC test conditions.

Does AOD2N100 support logic-level gate drive?

Yes, the AOD2N100 supports logic-level gate drive with a gate threshold voltage V_GS(th) range of 2.0 V to 4.0 V. It achieves R_DS(on) ≤ 3.5 Ω at V_GS = 4.5 V, making it compatible with 3.3 V and 5 V microcontrollers without external level shifters-though full enhancement (2.4 Ω) requires V_GS ≥ 10 V.

Is AOD2N100 qualified for automotive applications?

The AOD2N100 is not AEC-Q101 qualified. It is specified for industrial and commercial use only. For automotive body control modules, designers must perform system-level validation of temperature cycling, humidity, and vibration; AOD2N100's 125 mJ E_AS and TO-252 thermal performance support such evaluation but do not constitute automotive qualification.

What is the thermal resistance from junction to case (R_θJC) for AOD2N100?

The AOD2N100 has a typical junction-to-case thermal resistance R_θJC of 50 °C/W, measured from die junction to the center of the exposed drain pad. This value enables >1.5 W power dissipation with 1-in² 2-oz copper on FR4 when mounted per JEDEC TO-252 land pattern PO-00009.

Can AOD2N100 be used in parallel configurations?

Yes, the AOD2N100 can be paralleled for higher current handling, provided gate drive impedance is matched and source inductance is minimized. Its positive temperature coefficient of R_DS(on) promotes current sharing, but individual current limiting and thermal monitoring are recommended. Layout symmetry and Kelvin source connections improve stability in parallel AOD2N100 implementations.
