Product details
Overview
ZVN4424GQTA from Diodes Incorporated is an N-channel enhancement-mode vertical DMOSFET in SOT223 package, rated for 240 V drain-source breakdown voltage, 4.3 Ω RDS(ON) at VGS = 2.5 V / ID = 100 mA, and 500 mA continuous drain current at TA = +25°C. It serves as a high-voltage, low-threshold switching device in telecom line interface circuits and battery-powered DC-DC converters.
For engineers reviewing the ZVN4424GQTA datasheet, ZVN4424GQTA pinout, ZVN4424GQTA application, or ZVN4424GQTA equivalent, key selection criteria include its AEC-Q101 qualification, 240 V BVDSS, low 1.3 V typical VGS(TH), fast 5 ns tR/25 ns tF switching, and SOT223 thermal performance up to 150°C junction temperature.
Technical Context
This MOSFET employs vertical DMOS architecture optimized for high-voltage blocking and low on-resistance trade-off. Its 240 V BVDSS supports telecom line feed and high-side switching in 190 V DC bus applications, while the 1.3 V typical gate threshold enables direct drive from 3.3 V logic controllers.
Dynamic parameters-Ciss = 110–200 pF, tD(ON) = 2.5–5 ns, tF = 16–25 ns-are specified under 50 Ω source impedance and pulsed conditions (300 μs width, ≤2% duty), confirming suitability for medium-frequency (<1 MHz) power switching with minimal gate drive loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| BVDSS | 240 V - Supports operation across telecom -48 V line interfaces with 190 V DC hold-off margin |
| RDS(ON) | 4.3 Ω @ VGS = 2.5 V / ID = 100 mA - Enables efficient low-voltage gate drive in battery-powered systems |
| VGS(TH) | 0.8–1.8 V - Ensures reliable turn-on with 1.8 V or higher logic families without level-shifting |
| ID (continuous) | 500 mA @ TA = +25°C - Delivers stable current handling in thermally constrained SOT223 footprint |
| tF | 16–25 ns - Limits switching losses in 100–500 kHz DC-DC converter topologies |
| PTOT | 2.5 W @ TA = +25°C - Matches thermal dissipation capability of standard SOT223 PCB land patterns |
| TJ range | -55 to +150 °C - Validated for automotive under-hood and industrial ambient environments |

| Source | Reference node for gate control | Common return path for load current; ties to ground or negative rail in low-side switch configuration |
| Gate | Control input terminal | High-impedance MOS gate requiring <100 nA leakage; driven by microcontroller GPIO or dedicated driver |
| Drain (Pin 1) | Redundant drain connection | Second drain lead for mechanical stability and additional current path; electrically identical to tab |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TC; PPAP capable |
| Low VGS(TH) (1.3 V typ) | Enables direct interfacing with 1.8 V/3.3 V MCUs without external level shifters in space-constrained designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel high-voltage MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN24H3D5L-7 | 240 V BVDSS, 3.5 Ω RDS(ON) @ 4.5 V, SOT23-3 package, no exposed drain tab | Lower RDS(ON) but limited to 350 mA ID; unsuitable for >1 W thermal loads due to smaller package | Select for space-constrained logic-level switching where power dissipation <0.5 W |
| SI2302DS-T1-BE3 | 20 V BVDSS, 0.05 Ω RDS(ON) @ 4.5 V, SOT23-3, not AEC-Q101 qualified | Not rated for telecom or automotive high-voltage use; only suitable for ≤12 V battery systems | Select only for low-voltage consumer electronics with no safety or reliability certification needs |
Compared with DMN24H3D5L-7 and SI2302DS-T1-BE3, ZVN4424GQTA uniquely balances 240 V rating, AEC-Q101 compliance, SOT223 thermal capability, and 2.5 V logic compatibility-making it the sole option for certified high-voltage switching in automotive and telecom infrastructure.

FAQ
Is ZVN4424GQTA pin-compatible with ZVN4424FTA?
No. ZVN4424GQTA uses SOT223 (Type DN) with drain-tab and four terminals, while ZVN4424FTA is in TO-92 package with three leads and no thermal tab. Physical layout, thermal path, and pin assignment differ fundamentally-PCB redesign is required for substitution.
What is the maximum safe operating voltage for ZVN4424GQTA in continuous DC applications?
The absolute maximum drain-source voltage is 240 V, but continuous DC operation should be limited to ≤190 V to maintain ≥20% derating margin per IEC 61000-4-5 surge immunity requirements and ensure long-term reliability under thermal and voltage stress.
Does ZVN4424GQTA require a gate resistor for ESD protection in handheld equipment?
Yes. Although gate leakage is ≤100 nA, a 10–47 Ω series gate resistor is recommended to dampen ringing and limit peak current during fast-edge MCU PWM drive, especially in battery-powered devices where ESD transients may couple through unshielded traces.
Can ZVN4424GQTA be used in linear (analog) mode for constant-current source applications?
No. This device is characterized and qualified only for switching operation. Its Safe Operating Area (SOA) is not specified for linear mode, and prolonged operation in the ohmic region risks thermal runaway due to positive temperature coefficient of RDS(ON) and lack of SOA derating curves.
