Product details
Overview
ZVN2120GTA from Diodes Incorporated is a 200V N-channel enhancement-mode vertical MOSFET in SOT223 package, featuring 10Ω RDS(on) at VGS = 10V, 0.32A continuous drain current, and −55°C to +150°C operating temperature range; used as low-power load switch in automotive solenoid drivers and DC-DC converter secondary-side control.
For engineers reviewing the ZVN2120GTA datasheet, ZVN2120GTA pinout, ZVN2120GTA application, or ZVN2120GTA equivalent, key selection criteria include verified 200V BVDSS rating, pulsed drain capability up to 2A, thermal resistance of 62.5°C/W (junction-to-ambient), and RoHS-compliant matte tin annealed terminals suitable for lead-free reflow.
Technical Context
This discrete MOSFET operates in enhancement mode with gate threshold voltage between 1V and 3V, enabling direct logic-level drive from 3.3V/5V microcontrollers. Its vertical structure supports stable high-voltage blocking while maintaining low on-resistance for efficient low-current switching.
Dynamic parameters include 85pF input capacitance, 7pF reverse transfer capacitance, and sub-10ns turn-on delay-optimized for medium-speed power control where EMI and gate drive loss must be balanced against thermal constraints in compact SOT223 layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| BVDSS | 200V - supports operation across 24V automotive rails with margin for load dump transients |
| RDS(on) | 10Ω @ VGS=10V - delivers ≤32mW conduction loss at 0.32A ID, suitable for <1W load switching |
| ID (continuous) | 0.32A - rated for steady-state loads such as small relays, LED strings, or sensor bias circuits |
| tD(on) | 8ns - enables clean edge control in PWM frequencies up to ~10MHz without excessive ringing |
| PD | 2W - achievable with minimal copper pour in SOT223; derates to ~0.8W at +70°C ambient |
| TJ range | −55°C to +150°C - qualified for under-hood automotive environments per AEC-Q101 guidance |
Pinout & Package
Package: SOT223 (Type DN), surface-mount, 3-terminal plastic molded case with exposed drain tab for thermal relief; moisture sensitivity level 1 (J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | High-side power path output | Electrically connected to metal tab; requires PCB copper area ≥25mm² for thermal management |
| Source | Return path for load current | Common reference node for gate drive; ties directly to ground plane in low-noise configurations |
| Gate | Control input | High-impedance MOS input; requires <100nF local decoupling when driven by MCU GPIO to suppress ringing |
Key Features
| Feature | Design Value |
|---|---|
| V(BR)DSS > 200V | Guarantees reliable blocking under 12V/24V automotive transients including ISO 7637-2 pulse 5a (±100V) |
| RDS(on) ≤ 10Ω @ VGS = 10V | Enables use with standard 5V logic without level-shifting; reduces gate drive power in battery-powered systems |
| Lead-Free & Halogen-Free | Meets RoHS 3 and JEDEC J-STD-020; eliminates brominated flame retardants for safer end-of-life processing |
| Thermal Resistance θJA | 62.5°C/W - allows full 2W dissipation only with ≥2in² 2oz copper; typical design uses <0.5W for reliability |
Applications
| Automotive Solenoid Driver | DC-DC Converter Control |
|---|---|
Use Scenario: Driving 12V fuel injector solenoids in engine control units with PWM duty cycling. IC Role / Device Role / Timing Role: Low-side switch controlling coil current path; gate driven by 5V microcontroller PWM output. Use Value: 200V BVDSS withstands back-EMF spikes >150V during coil de-energization; 10Ω RDS(on) limits self-heating to <5°C rise at 0.3A. | Use Scenario: Secondary-side synchronous rectifier in isolated flyback converters for industrial sensors. IC Role / Device Role / Timing Role: N-channel MOSFET replacing Schottky diode to reduce forward drop and improve efficiency at light loads. Use Value: 8ns tD(on) and 8ns tR enable precise timing alignment with primary-side controller; 0.32A ID suffices for ≤5W output designs. |
| Low-Power Relay Interface | LED String Bias Switch |
Use Scenario: Controlling 5V/24V signal relays in programmable logic controllers (PLCs) with opto-isolated inputs. IC Role / Device Role / Timing Role: High-side or low-side load switch isolating microcontroller I/O from relay coil inductance. Use Value: 2A pulsed IDM handles relay inrush current; 150°C max TJ ensures operation in sealed enclosures up to +85°C ambient. | Use Scenario: Enabling/disabling 3–5 LED segments in automotive interior lighting modules. IC Role / Device Role / Timing Role: Constant-current bypass switch regulating segment brightness via PWM dimming at 1kHz. Use Value: 10Ω RDS(on) introduces <1% voltage error in 20mA LED chains; SOT223 footprint fits tight board spacing requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2004LKQ-7 | Lower RDS(on) = 4.5Ω @ VGS=10V; higher ID = 0.6A; same SOT223 package | Better suited for higher-current solenoids or faster-switching DC-DC topologies | Select when conduction loss reduction outweighs cost increase and layout change is acceptable |
| IRLML2502TRPBF | Logic-level VGS(th) = 1.0–2.0V; RDS(on) = 85mΩ @ VGS=4.5V; smaller SOT-23 package | Enables direct 3.3V MCU drive but limited to ≤20V systems and lower power | Choose for space-constrained 3.3V embedded systems where 200V rating is unnecessary |
Compared with ZVN2120GTA, DMN2004LKQ-7 offers superior conduction efficiency at higher currents, while IRLML2502TRPBF provides true logic-level compatibility in miniature form-neither matches the 200V BVDSS and thermal robustness of ZVN2120GTA in automotive-grade SOT223.

FAQ
Is ZVN2120GTA qualified to AEC-Q101?
No-ZVN2120GTA is not AEC-Q101 qualified. While its absolute maximum ratings and construction align with automotive environmental stress profiles, Diodes does not list it in their AEC-Q101 qualified portfolio. For production automotive applications requiring PPAP documentation and IATF 16949 traceability, contact Diodes directly for qualified alternatives like the DMN2004LKQ series.
Can ZVN2120GTA be used in high-frequency switching above 1MHz?
It is not recommended. With 85pF Ciss and 20ns tD(off), ZVN2120GTA exhibits significant gate charge and switching losses above 500kHz. At 1MHz, total switching loss exceeds conduction loss, reducing efficiency. Use only in PWM applications ≤200kHz or burst-mode control where average frequency remains low.
What is the thermal resistance from junction to PCB for ZVN2120GTA in standard SOT223 layout?
In a standard 1in² 2oz copper pad layout per Diodes' suggested footprint, θJC is approximately 25°C/W and θJA is 62.5°C/W. Actual performance depends on copper area: doubling pad size reduces θJA by ~15°C/W; adding internal thermal vias improves θJC by up to 30%.
Does ZVN2120GTA have integrated ESD protection on the gate?
No-ZVN2120GTA lacks on-chip gate ESD protection. The gate oxide is rated for ±20V VGSS, but real-world handling requires external 10kΩ series resistor and/or TVS clamp to prevent damage from static discharge or inductive kickback coupling. Diodes recommends gate resistors ≥47Ω for all driving circuits.
