Product details

Overview

ZVN4424ZTA from Diodes Incorporated is an N-channel enhancement-mode vertical DMOS FET in SOT-89 package, rated for 240 V drain-source breakdown voltage, 4.3 Ω R_DS(on) at V_GS = 10 V and I_D = 500 mA, and 300 mA continuous drain current at 25°C ambient. It serves as a high-voltage switching element in telecom hook-switch circuits, battery-powered equipment, and DC-DC converters requiring fast turn-on/turn-off times (t_d(on) = 5 ns typ., t_f = 25 ns typ.).

For engineers reviewing the ZVN4424ZTA datasheet, ZVN4424ZTA pinout, ZVN4424ZTA application, or ZVN4424ZTA equivalent, key selection criteria include verified 240 V BVDSS rating, low-threshold gate drive compatibility (V_GS(th) = 0.8–1.8 V), SOT-89 thermal performance under pulsed loads, and documented replacement guidance toward DMN30H4D0L for new designs.

Technical Context

This discrete MOSFET employs vertical DMOS construction to achieve high-voltage blocking with low on-resistance in a surface-mount SOT-89 outline. Its gate threshold voltage range (0.8–1.8 V) enables direct interface with 3.3 V and 5 V logic controllers without level-shifting, while its 40 V maximum gate-source voltage supports robust transient immunity.

Switching performance is characterized under 50 Ω source impedance with <5 ns pulse rise time: typical turn-off delay (t_d(off)) is 60 ns and fall time (t_f) is 25 ns at V_DD ≈ 50 V and I_D = 0.25 A. Input capacitance (C_iss = 200 pF max) and reverse transfer capacitance (C_rss = 15 pF max) are specified at V_DS = 25 V, V_GS = 0 V, f = 1 MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
BVDSS	240 V - Supports operation in 190 V DC telecom line interfaces and high-voltage DC-DC stages without avalanche stress.
RDS(on)	4.3 Ω @ VGS=10 V, ID=500 mA - Enables ≤2.15 W conduction loss at rated current; suitable for intermittent switching in battery-powered systems.
VGS(th)	0.8–1.8 V - Ensures reliable turn-on from standard 3.3 V microcontroller GPIOs without external gate drivers.
td(off) / tf	60 ns / 25 ns - Meets timing requirements for >1 MHz switching in isolated flyback or forward converter auxiliary circuits.
ID(continuous)	300 mA @ Tamb=25°C - Requires FR4 PCB pad (15×15×0.6 mm) for 1 W power dissipation; derates to zero at 150°C junction.
Ciss / Crss	200 pF / 15 pF @ VDS=25 V - Low input and feedback capacitance reduces gate drive power and improves EMI profile in high-frequency switchers.

Pinout & Package

Package: SOT-89 - Three-terminal surface-mount plastic package with exposed drain tab for thermal conduction to PCB copper. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control electrode	Receives logic-level voltage to modulate channel conductivity; requires <100 nA leakage handling per IGSS spec.
Pin 2 (Drain)	High-voltage output node	Connected to exposed metal tab; must be thermally anchored to ≥15×15 mm² copper pour for 1 W dissipation.
Pin 3 (Source)	Reference terminal	Serves as return path for load current; ties to system ground or floating reference depending on high-side/low-side topology.

Key Features

Feature	Design Value
Vertical DMOS structure	Enables 240 V blocking capability in compact SOT-89 footprint without lateral layout area penalty.
Low R_DS(on) (4.3 Ω)	Reduces conduction losses in battery-operated hook-switch circuits where duty cycle is low but voltage is high.
Fast switching (t_f = 25 ns)	Minimizes transition losses in telecom line interface circuits operating at ~100 kHz burst frequencies.
Low V_GS(th) range (0.8–1.8 V)	Permits direct drive from 3.3 V FPGA I/O banks or microcontroller pins without gate driver IC overhead.

Applications

Telecom Hook Switch

Battery-Powered Dialer

Use Scenario: Electronic replacement of mechanical hook switches in analog telephone line interface cards.

IC Role / Device Role / Timing Role: High-voltage N-channel switch controlling loop current flow between tip/ring and battery feed.

Use Value: 240 V BVDSS withstands ringing voltage transients up to 190 V peak; low R_DS(on) limits heat generation during sustained off-hook states.

Use Scenario: Low-power dial pulse generation in portable emergency call units powered by coin cells.

IC Role / Device Role / Timing Role: Digitally controlled line disconnect switch enabling precise pulse timing via MCU GPIO.

Use Value: Sub-2 V gate threshold ensures full enhancement with 3 V supply; 300 mA rating supports 20–50 mA dial pulses with margin.

DC-DC Converter Auxiliary Switch

Earth Recall Circuit

Use Scenario: Synchronous rectification or gate drive isolation in 48–190 V input isolated DC-DC modules.

IC Role / Device Role / Timing Role: Low-side switch in active clamp or auxiliary winding control circuitry.

Use Value: 60 ns t_d(off) and 25 ns t_f support >500 kHz switching; C_rss = 15 pF minimizes Miller-induced shoot-through risk.

Use Scenario: Ground-fault detection and automatic line disconnection in safety-critical telecom infrastructure.

IC Role / Device Role / Timing Role: Fast-acting isolation switch triggered by earth leakage sensing comparator output.

Use Value: 5 ns t_d(on) enables sub-microsecond response to fault conditions; 100 µA I_DSS at 240 V ensures minimal standby leakage.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN30H4D0L	30 V V_DS, 4.2 mΩ R_DS(on), 12 A I_D, SOT-23 package	Lower voltage rating but vastly superior current and thermal capability; not suitable for 190 V line applications.	Recommended only for new designs targeting ≤30 V systems where high current density and small footprint are critical.
ZVP4424Z	P-channel complement; same 240 V BVDSS, 4.3 Ω R_DS(on), SOT-89 package	Used in high-side configurations where gate drive referencing is simpler than N-channel bootstrap solutions.	Select when circuit topology requires source-follower or high-side switching with referenced gate control.

Compared with ZVN4424ZTA, DMN30H4D0L trades 240 V capability for ultra-low R_DS(on) and higher current in a smaller package, while ZVP4424Z provides functional symmetry in P-channel form-neither is a drop-in replacement due to polarity and voltage-class mismatch.

FAQ

Is ZVN4424ZTA suitable for new designs?

No. The datasheet explicitly states "NOT RECOMMENDED FOR NEW DESIGN" and recommends DMN30H4D0L as a modern alternative. ZVN4424ZTA remains available for legacy repair and continuity, but lacks RoHS-2 compliance documentation, AEC-Q101 qualification, and long-term supply assurance beyond 2026.

What is the maximum safe operating temperature for ZVN4424ZTA?

The junction temperature must not exceed +150°C, and storage temperature range is –55°C to +150°C. At ambient temperatures above 25°C, continuous drain current must be linearly derated from 300 mA using the specified thermal resistance curve; full 1 W power dissipation requires the recommended 15×15 mm² FR4 copper pad.

Can ZVN4424ZTA replace ZVP4424Z in a circuit?

No - ZVN4424ZTA is N-channel and ZVP4424Z is P-channel. Swapping them would invert switching logic and likely cause latch-up or short-circuit conditions. They are complementary devices intended for different topologies: ZVN4424ZTA for low-side switching, ZVP4424Z for high-side or level-shifted configurations.

What gate drive voltage is required to fully enhance ZVN4424ZTA?

A minimum of 2.5 V is sufficient to begin conduction (V_GS(th) max = 1.8 V), but full enhancement to achieve R_DS(on) = 4.3 Ω requires V_GS = 10 V at I_D = 500 mA. At V_GS = 5 V, R_DS(on) rises to ~6 Ω, increasing conduction loss by >40% under same load.
