Product details
Overview
DMN30H14DLY-13 from Diodes Incorporated is a 300V N-channel enhancement-mode MOSFET in SOT89 package, with RDS(ON) = 14Ω @ VGS = 10V and ID = 0.21A at TA = +25°C. It serves as a low-power switching device in battery-operated systems, solid-state relays, and discrete load drivers for lamps, solenoids, and displays.
For engineers reviewing the DMN30H14DLY-13 datasheet, DMN30H14DLY-13 pinout, DMN30H14DLY-13 application, or DMN30H14DLY-13 equivalent, key selection criteria include gate threshold voltage (1–3V), low input capacitance (96pF), fast switching speed (tR = 8.6ns), and thermal resistance (RθJA = 132°C/W on FR-4).
Technical Context
This MOSFET employs planar silicon technology optimized for high-voltage, low-current switching with enhanced gate control linearity. Its 1–3V VGS(TH) enables direct drive from 3.3V/5V logic, while low Ciss (96pF) and Crss (3.2pF) support efficient high-frequency operation up to several hundred kHz.
The integrated body diode has VSD = 0.7–1.2V at IS = 0.3A and tRR = 43ns, supporting moderate-speed freewheeling in inductive loads. Thermal design is constrained by RθJC = 9.6°C/W and PD = 0.9W on standard FR-4 layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 300V - supports off-state blocking in 240V AC-derived DC rails and industrial power supplies |
| RDS(ON) | 14Ω @ VGS = 10V - delivers ≤0.3W conduction loss at 0.21A, suitable for <1W load switching |
| VGS(TH) | 1–3V - ensures reliable turn-on with 3.3V microcontroller GPIO without level-shifting |
| Ciss | 96pF - minimizes gate drive energy and enables <500kHz PWM operation with low gate resistance |
| tR/tF | 8.6ns / 12ns - reduces switching transition losses in duty-cycled low-power control circuits |
| RθJA | 132°C/W - requires minimal copper area for thermal management in space-constrained SOT89 layouts |
| ID (max) | 0.21A continuous - rated for sustained current in relay/solenoid driver stages with derating above +70°C |
Pinout & Package
Package: SOT89 - surface-mount, single-ended heat-sinkable plastic package with exposed drain tab (pin 2), rated for 0.9W dissipation on FR-4 PCB with minimum pad layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate | Control terminal; accepts 0–10V logic-level signals; low Ciss enables fast charging with ≤25Ω series resistor |
| Pin 2 (D) | Drain | High-side switch node; electrically connected to exposed metal tab for thermal conduction and EMI shielding |
| Pin 3 (S) | Source | Return path for load current; referenced to system ground in low-side configuration; defines VGS control loop |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | VGS(TH) = 1–3V ensures full enhancement with 3.3V MCU outputs, eliminating need for gate drivers in low-speed applications |
| Low input capacitance | Ciss = 96pF reduces gate charge (Qg = 4nC) and drive power, enabling efficient operation from weak GPIO sources |
| Fast switching speed | tR = 8.6ns and tF = 12ns minimize overlap losses in PWM-controlled resistive/inductive loads below 200kHz |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900ppm Br+Cl, <1000ppm Sb) meets IEC 61249-2-21 and JEDEC J-STD-020 Level 1 moisture sensitivity |
Applications
| Battery-Powered Sensor Node | Solid-State Relay Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel high-voltage low-current switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN30H14DLW-7 | Same die in SOT23-3 package; RθJA = 220°C/W; PD = 0.35W; lower thermal capability | Restricted to sub-100mA loads and ambient temperatures <50°C due to higher thermal resistance | Select when board space is critical and power dissipation remains below 0.2W; avoid in thermally dense layouts |
| ZXMN3A03E6TA | 30V VDSS, 3Ω RDS(ON) @ 4.5V, 3.5A ID; incompatible voltage rating for 240V-derived rails | Not usable in 300V blocking applications; limited to low-voltage DC-DC and motor control | Only consider if redesigning for ≤30V systems where higher current and lower RDS(ON) are required |
Compared with DMN30H14DLY-13, DMN30H14DLW-7 trades thermal performance for footprint reduction, while ZXMN3A03E6TA offers superior conduction efficiency but fails at 300V blocking-making DMN30H14DLY-13 uniquely suited for compact, high-voltage, low-power switching where both voltage margin and thermal manageability matter.

FAQ
Is DMN30H14DLY-13 suitable for automotive applications?
No-DMN30H14DLY-13 is not AEC-Q101 qualified and lacks PPAP documentation or IATF 16949 manufacturing certification. Diodes explicitly states that automotive-grade variants require direct consultation; this part is intended for industrial and consumer use only.
What is the maximum safe operating temperature for continuous operation?
The junction temperature must not exceed +150°C. At TA = +70°C, the derated continuous drain current is 0.16A (per datasheet Note 6), and thermal design must account for RθJA = 132°C/W on standard FR-4 layout with minimum copper.
Can DMN30H14DLY-13 be used in high-frequency PWM applications?
Yes-its 8.6ns rise time, 12ns fall time, and low Ciss/Crss support PWM frequencies up to ~500kHz in low-duty-cycle, low-current scenarios; however, gate drive strength and PCB layout critically affect achievable edge rates and EMI.
Does the SOT89 package provide thermal relief through the drain tab?
Yes-the drain (Pin 2) is internally connected to the exposed metal tab, which serves as the primary thermal path. Effective heat transfer requires soldering the tab to ≥1-inch² of 2oz copper on the PCB bottom layer, achieving RθJA = 55°C/W per Note 6.
