Product details
Overview
DMN2030UCA4 from Diodes Incorporated is an N-channel enhancement-mode MOSFET optimized for low on-resistance (23.4 mΩ @ VGS = 3.8 V) and high-efficiency power switching in space-constrained battery management and load-switching applications, with 20 V VSSS, 6.3 A IS (TA = +25°C), and a 1.15 mm × 1.15 mm DSN1111-4 package.
For engineers reviewing the DMN2030UCA4 datasheet, DMN2030UCA4 pinout, DMN2030UCA4 application, or DMN2030UCA4 equivalent, this page delivers verified electrical parameters, thermal performance data, CSP footprint constraints, gate threshold behavior across temperature, and real-world selection guidance for battery protection circuits requiring ultra-low-profile discrete switches.
Technical Context
This MOSFET employs a trench-gate silicon process to achieve sub-25 mΩ RSS(ON) at logic-level gate drive (≥2.5 V), enabling direct interface with 3.3 V microcontrollers without level-shifting. Its integrated gate protection diode supports bidirectional transient suppression in battery-side switching paths.
The device operates over –55°C to +150°C junction temperature, with normalized RSS(ON) variation ≤1.4× across that range at VGS = 4.5 V, and exhibits 5.6 nC total gate charge for fast turn-on (tD(ON) = 378 ns) while maintaining low Crss (54 pF) to minimize Miller-induced shoot-through risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VSSS | 20 V - Maximum source-source blocking voltage for single-cell Li-ion and USB PD 3.0 input stage protection |
| RSS(ON) | 23.4 mΩ @ VGS = 3.8 V - Enables <120 mW conduction loss at 2 A continuous current in compact battery packs |
| IS | 6.3 A @ TA = +25°C - Supports high-current load switching in portable medical and wearables with minimal copper area |
| Qg | 5.6 nC - Allows efficient 1 MHz PWM control with <1.5 W gate driver power at 5 V supply |
| RθJA | 126 °C/W - Thermal resistance measured on FR-4 with minimum pad layout, defining heatsinking requirements for 1 W dissipation |
| VGS(TH) | 0.35–1.4 V - Ensures reliable turn-on with 1.8 V/3.3 V I/O domains and low-voltage brown-out detection |
| Ciss | 523 pF - Determines input capacitance loading on gate drivers in high-frequency synchronous buck stages |
Pinout & Package
Package: X4-DSN1111-4 - Ultra-thin chip-scale package (1.15 mm × 1.15 mm, 0.120 mm height) with NiAu-plated terminals, moisture sensitivity level 1, and solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S1 / S2 | Source (dual parallel) | Low-impedance return path; both pins must be connected to ground plane for rated RSS(ON) and thermal performance |
| G | Gate | Control terminal accepting 0–12 V drive; internal protection diode clamps negative transients to source |
| D | Drain | High-side or low-side power path connection; exposed drain pad provides primary thermal conduction path to PCB |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 1.15 mm × 1.15 mm CSP enables placement in <1.5 mm² board area-critical for multi-cell battery gauge modules |
| Logic-level gate drive | Turns fully on at VGS ≥ 2.5 V, eliminating need for external gate drivers in 3.3 V system rails |
| Low thermal resistance | 65 °C/W RθJA (with recommended pad layout) allows 1.9 W continuous dissipation without heatsink |
| Automotive-qualified option | Same die available in AEC-Q101 qualified version (DMN2030UCA4Q) for functional safety-critical battery disconnects |
| Green compliance | Halogen- and antimony-free, RoHS 3 compliant (≤900 ppm Br/Cl, ≤1000 ppm Sb), suitable for EU medical devices |

FAQ
What is the maximum continuous drain current for DMN2030UCA4 at 70°C ambient?
The DMN2030UCA4 supports 5.0 A continuous source current at TA = +70°C with VGS = 4.5 V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the DSN1111-4 package on standard FR-4 PCBs without enhanced copper pours.
Does DMN2030UCA4 include integrated ESD protection on the gate terminal?
No-DMN2030UCA4 does not integrate gate ESD protection diodes. The datasheet specifies ±12 V maximum VGS and recommends external series gate resistors (≥10 Ω) and TVS clamping for systems exposed to human-body-model (HBM) discharges exceeding 2 kV.
Can DMN2030UCA4 be used in reverse conduction mode (source-to-drain current flow)?
Yes-the device contains an intrinsic body diode with VSD ≤ 1.0 V at IS = 1.7 A and VGS = 0 V, enabling bidirectional current flow in battery backup and OR-ing configurations. However, forward voltage increases with temperature, reaching ~1.2 V at 150°C junction.
Is the X4-DSN1111-4 package compatible with standard reflow profiles for lead-free soldering?
Yes-the X4-DSN1111-4 package is rated for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260°C and moisture sensitivity level 1, allowing unlimited floor life and compatibility with standard Pb-free assembly processes without baking.
