Product details

Overview

ZVN4424G from Diodes Incorporated is an N-channel enhancement-mode vertical DMOSFET in SOT223 package, rated for 240 V drain-source breakdown voltage, 500 mA continuous drain current at +25°C, and 4.3 Ω R_DS(ON) at V_GS = 2.5 V. It serves as a high-voltage, low-threshold switching device in telecom hook-switch circuits and battery-powered DC-DC converters.

For engineers reviewing the ZVN4424G datasheet, ZVN4424G pinout, ZVN4424G application, or ZVN4424G equivalent, key selection criteria include its 240 V BVDSS rating, sub-2 V gate threshold, 2.5 W power dissipation at TA = +25°C, fast switching times (t_D(OFF) ≤ 60 ns), and SOT223 thermal performance in space-constrained power management designs.

Technical Context

This MOSFET employs vertical DMOS architecture to achieve high voltage blocking with low on-resistance. Its 0.8–1.8 V gate threshold enables direct drive from 3.3 V logic and supports low-power control in battery-operated systems.

Dynamic parameters-including 110–200 pF input capacitance, 15–25 pF output capacitance, and 40–60 ns turn-off delay-are optimized for efficient switching in 100 kHz–1 MHz DC-DC topologies where gate drive loss and switching transition time critically impact efficiency.

Key Specifications

Parameter	Value and Actual Design Meaning
BVDSS	240 V - Withstands up to 240 V drain-source voltage before avalanche conduction, suitable for 190 V DC bus applications.
RDS(ON)	4.3 Ω @ VGS = 2.5 V - Enables full enhancement with standard 3.3 V microcontroller GPIO, minimizing conduction loss in low-power switches.
ID (continuous)	500 mA @ TA = +25°C - Supports load switching in telecom line interface cards and portable equipment without forced cooling.
tD(OFF)	40–60 ns - Reduces switching transition time in high-frequency DC-DC converters, lowering overlap loss during PWM operation.
PTOT	2.5 W @ TA = +25°C - Delivers usable power handling in SOT223 footprint with PCB copper pour, typical for board-level power routing.
VGS(TH)	0.8–1.8 V - Ensures reliable turn-on across temperature and process variation using low-voltage logic drivers.
Ciss	110–200 pF - Determines gate charge requirement (~2.5 nC typical) for driving with minimal gate resistor sizing.

Pinout & Package

Package: SOT223 (Type DN), surface-mount, thermally enhanced plastic case with exposed drain pad. Molded "Green" compound (UL 94V-0), lead-free, halogen- and antimony-free.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current-carrying terminal	Connected to exposed metal tab; primary thermal path to PCB copper pour; electrically tied to internal MOSFET drain structure.
Source (S)	Reference node for gate control and current return	Provides low-impedance return path; used as ground reference for gate drive in low-side switch configuration.
Gate (G)	Control electrode	High-impedance input requiring <100 nA leakage; driven by logic-level signal to modulate channel conductivity.

Key Features

Feature	Design Value
240 V BVDSS rating	Enables use in 190 V telecom line interfaces and industrial HV DC-DC stages without derating or series stacking.
4.3 Ω RDS(ON) @ VGS = 2.5 V	Permits direct drive from 3.3 V MCU outputs, eliminating level-shifter circuitry in battery-powered hook-switch modules.
Fast switching (tD(OFF) ≤ 60 ns)	Reduces energy loss during transitions in 500 kHz flyback or buck converters, improving system efficiency above 85%.
RoHS 3 & "Green" compliant	Meets EU 2015/863/EU requirements with Br+Cl <1500 ppm and Sb <1000 ppm-supports eco-design certification for telecom equipment.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel high-voltage low-threshold MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZVN4424F	Same die, SOT23-3 package; RDS(ON) = 4.3 Ω @ VGS = 2.5 V but lower PTOT (1.25 W).	Limited to <250 mA continuous current due to thermal constraints; unsuitable for 500 mA telecom loads.	Select only when board space is critical and power dissipation remains below 0.6 W.
DMN24H3D5L	240 V BVDSS, 3.5 Ω RDS(ON) @ VGS = 4.5 V, but VGS(TH) = 1.0–2.5 V; SOT223-3.	Requires ≥4.5 V gate drive for optimal RDS(ON); less compatible with 3.3 V logic without level shift.	Prefer when higher gate drive voltage is available and lower on-resistance justifies added complexity.

Compared with ZVN4424F and DMN24H3D5L, the ZVN4424G uniquely balances 240 V capability, 3.3 V logic compatibility, and 500 mA current handling in SOT223-making it the only option qualified for sustained telecom hook-switch duty without thermal derating.

FAQ

What is the maximum continuous drain current for ZVN4424G at +70°C ambient?

At TA = +70°C, the continuous drain current is derated to 350 mA. This is calculated using the 2.5 W power dissipation limit and the thermal resistance of SOT223 (typically 100°C/W junction-to-ambient with minimal copper), resulting in a 100°C junction rise that reduces safe current handling proportionally.

Is ZVN4424G suitable for automotive applications?

The ZVN4424GQ variant-not the base ZVN4424G-is AEC-Q101 qualified and PPAP capable. The standard ZVN4424G lacks automotive qualification documentation, temperature cycling validation, and IATF 16949 traceability, so it is not recommended for automotive ECUs or ADAS modules.

How does the gate threshold voltage affect drive circuit design?

With VGS(TH) spanning 0.8–1.8 V, the ZVN4424G turns on fully at 2.5 V, allowing direct connection to 3.3 V microcontrollers. However, gate drive must source ≥10 mA peak to charge Ciss rapidly; a 10 Ω series resistor is typical to damp ringing without compromising tR/tF.

Can ZVN4424G be used in linear (analog) mode for voltage regulation?

No-it is not characterized or guaranteed for linear operation. The Safe Operating Area (SOA) curve is not provided in the datasheet, and prolonged operation in the linear region risks thermal runaway due to positive temperature coefficient of RDS(ON) and limited SOA at high VDS/ID combinations.
