Product details

Overview

DMN3022LFG-7 from Diodes Incorporated is a dual-channel 30V N-channel enhancement-mode MOSFET in PowerDI3333-8 (Type D) package, featuring Q1 with R_DS(ON) = 22 mΩ @ V_GS = 5 V, I_D = 10 A and Q2 with R_DS(ON) = 8 mΩ @ V_GS = 5 V, I_D = 10 A. It serves as a synchronous rectifier and power switch in high-efficiency DC-DC converters, supporting bidirectional current flow and fast switching in compact power management circuits.

For engineers reviewing the DMN3022LFG-7 datasheet, DMN3022LFG-7 pinout, DMN3022LFG-7 application, or DMN3022LFG-7 equivalent, key selection criteria include channel asymmetry (Q1/Q2 R_DS(ON) ratio of 2.75×), low gate charge (Q_g = 2.8–3.7 nC for Q1, 6.1–8 nC for Q2), and thermal resistance R_θJA = 64 °C/W - critical for thermally constrained point-of-load designs.

Technical Context

This dual MOSFET integrates two independently controlled N-channel devices in a single PowerDI3333-8 package: Q1 optimized for higher voltage tolerance and robust UIS capability (E_AS = 28 mJ), Q2 engineered for ultra-low conduction loss (R_DS(ON) = 6.4–8 mΩ). Both channels share common source terminals but feature separate gates and drains, enabling asymmetric synchronous buck or OR-ing configurations.

The device uses trench-gate silicon technology to achieve low input capacitance (C_iss = 370–481 pF for Q1; 766–996 pF for Q2) and fast switching (t_F = 1.9 ns for Q1, 2.4 ns for Q2), while maintaining 100% production-tested UIS performance and RoHS-compliant, halogen-free packaging.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30 V maximum drain-source voltage per channel - supports 24 V input rails with 25 % margin against transients
R_DS(ON) Q1 / Q2	22 mΩ / 8 mΩ @ V_GS = 5 V, I_D = 10 A - enables <1.5 W conduction loss per channel at 10 A continuous current
Q_g Q1 / Q2	2.8–3.7 nC / 6.1–8 nC @ V_GS = 4.5 V - determines gate drive power and switching loss in 500 kHz–2 MHz DC-DC topologies
C_iss Q1 / Q2	370–481 pF / 766–996 pF @ V_DS = 15 V - impacts EMI filtering requirements and gate driver sizing
I_D Continuous	7.6 A (Q1) / 12 A (Q2) @ T_A = +70 °C - defines maximum steady-state current under natural convection on FR-4 PCB
R_θJA	64 °C/W - sets junction-to-ambient temperature rise at 1.25 W dissipation, limiting usable power in unheatsinked layouts
E_AS	28 mJ (Q1) / 92 mJ (Q2) - quantifies ruggedness against inductive turn-off stress in synchronous rectification

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3025LFG-7	R_DS(ON) = 25 mΩ / 10 mΩ (Q1/Q2); higher Q_g (3.5–4.5 nC / 7.2–9.2 nC)	Slightly lower efficiency at 10 A due to +13.6 % R_DS(ON) on Q1; identical pinout and thermal profile	Select when tighter R_DS(ON) tolerance (±15 % vs. ±20 %) is required for production binning consistency.
SI6926ADQ-T1-GE3	Single-channel 30 V MOSFET pair in SO-8; R_DS(ON) = 12 mΩ / 12 mΩ; no integrated asymmetry	Requires two separate packages for Q1/Q2 roles; lacks E_AS rating and UIS testing	Choose only if board layout mandates SO-8 footprint and symmetric channel performance suffices.

Compared with DMN3022LFG-7, DMN3025LFG-7 trades marginal R_DS(ON) increase for improved process yield, while SI6926ADQ-T1-GE3 sacrifices avalanche ruggedness and channel optimization for legacy package compatibility - making DMN3022LFG-7 uniquely suited for high-reliability, space-constrained synchronous rectification.

FAQ

What is the maximum continuous drain current for each channel at 70°C ambient?

At T_A = +70 °C, Q1 supports 12 A continuous drain current and Q2 supports 12 A - both limited by package thermal resistance and PCB copper area. The datasheet specifies 12 A for Q1 and 12 A for Q2 under TC = +70 °C conditions, with derating applied above that temperature based on R_θJA = 64 °C/W.

Can DMN3022LFG-7 be used in a bootstrap-gated high-side configuration?

No - DMN3022LFG-7 contains two N-channel MOSFETs with common-source topology and no integrated level-shifting or floating supply capability. It requires separate gate drivers with isolated supplies or charge pumps for high-side operation; it is not internally configured for bootstrap biasing.

Is the PowerDI3333-8 (Type D) package lead-free and RoHS compliant?

Yes - the DMN3022LFG-7 uses matte tin annealed over copper leadframe and conforms to EU Directive 2015/863/EU (RoHS 3), with halogen and antimony content below 900 ppm Br, 900 ppm Cl, and 1000 ppm Sb, certified as "Green" per Diodes Incorporated's material definitions.

How does the Q1/Q2 asymmetry benefit synchronous rectifier designs?

The 2.75× lower R_DS(ON) of Q2 versus Q1 allows it to serve as the primary synchronous rectifier (carrying higher average current), while Q1 handles higher-voltage, lower-duty-cycle switching - reducing total conduction loss by up to 35 % compared to symmetric dual-MOSFET solutions in buck converters operating at 30–50 % duty cycle.
