Product details

Overview

ZVN2120G from Diodes Incorporated is a 200V N-channel enhancement-mode vertical MOSFET in SOT223 package, featuring 10Ω R_DS(on) at V_GS = 10V, 0.32A continuous drain current, and −55°C to +150°C operating temperature range. It serves as a low-power switching device in automotive solenoid drivers and DC-DC converter primary-side control circuits.

For engineers reviewing the ZVN2120G datasheet, ZVN2120G pinout, ZVN2120G application, or ZVN2120G 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 MOSFET employs a vertical DMOS structure optimized for high-voltage blocking with low on-resistance trade-off. Its gate threshold voltage (1–3V) enables direct drive from 3.3V/5V logic, while dynamic parameters-C_iss = 85pF, t_D(on) = 8ns-support efficient switching in sub-MHz power stages.

The device is characterized under pulsed conditions (300µs width, ≤2% duty cycle) to minimize self-heating effects. All maximum ratings-including 2W power dissipation and ±20V gate-source voltage-are specified at T_A = +25°C unless otherwise noted, with guaranteed TJ range from −55°C to +150°C.

Key Specifications

Parameter	Value and Actual Design Meaning
BVDSS	200V - Withstands 200V drain-source blocking voltage before avalanche conduction begins.
RDS(on)	10Ω @ VGS=10V - Delivers low conduction loss in low-current (<320mA) switching applications.
ID (continuous)	0.32A - Maximum steady-state drain current at TA=+25°C with adequate PCB copper area.
tD(on)/tR	8ns/8ns - Fast turn-on delay and rise time enable efficient operation in 100–500kHz DC-DC topologies.
Ciss	85pF - Input capacitance determines gate drive strength requirement and switching speed sensitivity.
PD	2W - Power dissipation limit at TA=+25°C; derates to zero at +150°C junction temperature.
TJ Range	−55°C to +150°C - Qualified for under-hood automotive environments and industrial ambient extremes.

Pinout & Package

Package: SOT223 (Type DN), surface-mount, 4-pin outline with exposed drain tab (pin 4) for thermal conduction. Molded plastic body meets UL 94V-0 flammability rating; moisture sensitivity level 1 per J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate	Control terminal; requires ≥1V VGS(th) to initiate conduction; rated for ±20V max voltage swing.
Pin 2 (S)	Source	Reference node for gate drive; tied to ground or low-side return path in common-source configuration.
Pin 3 (D)	Drain	High-side power output node; electrically connected to exposed metal tab (Pin 4) for thermal management.
Pin 4 (Tab)	Drain (thermal)	Internally bonded to drain; must be soldered to large copper pour for effective heat dissipation (RθJA = 62.5°C/W).

Key Features

Feature	Design Value
200V Drain-Source Breakdown	Enables use in 12V/24V automotive systems with load-dump transients up to 120V and design margin.
10Ω RDS(on) at 10V Gate Drive	Reduces I²R losses in <320mA switching paths, supporting thermally constrained PCB layouts.
SOT223 Thermal Pad Integration	Exposed drain tab allows direct thermal coupling to PCB copper, improving reliability in sustained pulse operation.
RoHS & Halogen-Free Compliance	Meets EU RoHS 3 (2015/863/EU) and "Green" definition: Br+Cl <1500ppm, Sb <1000ppm.

Applications

Use Scenario: Driving 12V fuel injector or HVAC actuator solenoids in passenger vehicles.

IC Role / Device Role / Timing Role: Low-side switch controlling coil energization/de-energization cycles.

Use Value: 200V BVDSS withstands inductive kickback spikes without clamping diode; 2A pulsed ID supports peak coil currents.

Use Scenario: Primary-side switch in isolated flyback or non-isolated buck converter for sensor power rails.

IC Role / Device Role / Timing Role: High-voltage, low-duty-cycle switching element in <500kHz topology.

Use Value: 8ns turn-on delay and 85pF Ciss reduce switching losses at moderate frequencies with minimal gate drive overhead.

Industrial Relay Interface

LED Load Switch

Use Scenario: Solid-state replacement for electromechanical relays in PLC I/O modules.

IC Role / Device Role / Timing Role: General-purpose low-current load switch with fast response.

Use Value: 0.32A continuous rating and 150°C TJ support long-term operation in sealed enclosures without forced air cooling.

Use Scenario: On/off control of high-brightness LED strings in signage or indicator panels.

IC Role / Device Role / Timing Role: Constant-current or PWM-controlled series switch.

Use Value: 10Ω RDS(on) limits voltage drop to <3.2V at 320mA, preserving forward voltage headroom for LED string regulation.

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
ZVN3310F	Higher RDS(on) = 15Ω @ VGS=10V; same 200V BVDSS and SOT223 package.	Lower efficiency in continuous conduction mode; higher self-heating at 320mA.	Prefer when cost sensitivity outweighs conduction loss; verify thermal margin in same layout.
DMN2004LK3	Lower BVDSS = 60V; RDS(on) = 4.5Ω @ VGS=10V; same SOT223 footprint but different pinout (G-D-S).	Not suitable for 200V applications; requires PCB redesign due to reversed drain/source pins.	Select only for 12–24V systems where lower on-resistance justifies voltage derating and layout change.

Compared with ZVN3310F and DMN2004LK3, the ZVN2120G uniquely balances 200V capability with sub-10Ω on-resistance in SOT223-making it the only option among the three qualified for automotive solenoid drivers requiring both high-voltage transient immunity and low thermal resistance.

FAQ

Is ZVN2120G qualified to AEC-Q101 for automotive use?

No-ZVN2120G is not AEC-Q101 qualified. While it meets automotive-grade temperature range (−55°C to +150°C) and is used in automotive solenoid drivers, Diodes explicitly states that AEC-Q101 qualification requires separate PPAP documentation and IATF 16949 manufacturing controls, which must be requested directly from their automotive team.

What is the thermal resistance from junction to ambient (RθJA) for ZVN2120G in standard SOT223 layout?

The datasheet specifies RθJA = 62.5°C/W for the SOT223 package under standard JEDEC test conditions (1-inch² copper pad, 1oz Cu). This value assumes no additional heatsinking; actual performance improves with larger copper areas or thermal vias beneath the exposed drain tab.

Can ZVN2120G be driven directly from a 3.3V microcontroller GPIO?

Yes-its gate threshold voltage (VGS(th)) is 1–3V, so a 3.3V logic signal fully enhances the channel. However, RDS(on) rises significantly below VGS = 10V (e.g., ~25Ω at VGS = 4.5V), so full 10V gate drive is recommended for minimum conduction loss in continuous operation.

Does ZVN2120G include an integrated body diode, and what are its characteristics?

Yes-it has a built-in parasitic body diode with reverse recovery time (t_rr) not specified in the datasheet. The diode's forward voltage is ~1.2V at IF = 250mA, and it supports bidirectional current flow during inductive flyback, though external Schottky clamping is recommended for high-reliability solenoid applications.
