Product details

Overview

ZVP4424G from Diodes Incorporated is a P-channel enhancement-mode vertical DMOSFET rated for -240 V drain-source voltage, 9 Ω R_DS(ON) at V_GS = -10 V, and -480 mA continuous drain current at +25°C. It serves as a high-voltage electronic hook switch in telecom line interface circuits and low-power battery-operated equipment.

For engineers reviewing the ZVP4424G datasheet, ZVP4424G pinout, ZVP4424G application, or ZVP4424G equivalent, key selection criteria include verified -240 V BVDSS rating, gate threshold of -0.7 to -2.0 V, R_DS(ON) performance at low gate drive (-3.5 V), thermal resistance (50 °C/W), and SOT223 package compatibility with FR-4 PCB layouts.

Technical Context

This device uses vertical DMOS architecture optimized for high-voltage blocking and low-conduction loss in normally-off switching applications. Its -240 V BVDSS and -2.0 V maximum V_GS(TH) enable reliable turn-on with standard logic-level negative gate drive in telecom hook-switch and battery-isolation circuits.

Thermal design is constrained by R_θJA = 50 °C/W on FR-4 with 1-inch² copper pad, and safe operating area (SOA) is limited by R_DS(ON) at DC and pulse widths down to 100 µs. Dynamic parameters-including t_D(OFF) = 26–40 ns and C_iss = 100–200 pF-support fast switching in low-duty-cycle control paths.

Key Specifications

Parameter	Value and Actual Design Meaning
BVDSS	-240 V - Enables direct interface with -48 V telecom line voltages and withstands transient surges up to ITU-T K.20/21 levels.
RDS(ON) @ VGS = -10 V	9 Ω max - Limits conduction loss to ≤2.0 mW at -200 mA, suitable for low-duty-cycle hook-switch actuation.
VGS(TH)	-0.7 to -2.0 V - Ensures reliable turn-on with simple negative-bias gate drivers (e.g., open-collector logic or microcontroller GPIO with pull-up).
ID (continuous)	-480 mA @ TA = +25°C - Supports sustained current for electromechanical relay replacement in line-card supervision circuits.
RθJA	50 °C/W - Requires minimum 1-inch² 2 oz copper pad for thermal management; derates to ~1.25 W at +70°C ambient.
Ciss	100–200 pF @ VDS = -25 V - Determines gate drive power requirement and switching speed in low-frequency (<100 kHz) control loops.

Pinout & Package

Package: SOT223 (Type DN), surface-mount, 3-terminal plastic molded case with exposed drain tab for thermal conduction. Mold compound is halogen- and antimony-free, UL 94V-0 rated.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current-carrying terminal (connected to internal MOSFET channel)	Exposed metal tab - must be soldered to large copper pour for thermal dissipation and electrical connection.
Source (S)	Reference node for gate drive and current return path	Connected to system ground or negative rail; defines VGS reference point for threshold behavior.
Gate (G)	Control electrode for channel formation	High-impedance input requiring <100 nA leakage; sensitive to ESD; requires series resistor for ringing suppression.

Key Features

Feature	Design Value
P-channel enhancement mode	Normally-off operation ensures fail-safe behavior in telecom line interface-no current flows without active gate bias.
Low VGS(TH) range (-0.7 to -2.0 V)	Enables direct drive from -3.3 V or -5 V logic outputs without level-shifting circuitry.
RDS(ON) = 8.8 Ω typical @ VGS = -3.5 V	Reduces gate driver complexity and power consumption in battery-powered hook-switch modules.
Lead-free, RoHS 3 & "Green" compliant	Meets automotive and industrial environmental requirements: <900 ppm Br/Cl, <1000 ppm Sb, no intentionally added Pb.

Applications

Use Scenario: Reverse-polarity protection and load switching in portable medical monitors powered by Li-ion batteries.

IC Role / Device Role / Timing Role: Low-threshold P-MOSFET used in high-side disconnect path to prevent reverse current flow during battery swap or fault conditions.

Use Value: Operates reliably with minimal gate drive overhead, preserving battery life while meeting IEC 60601-1 creepage/clearance requirements.

Electronic Hook Switch

Industrial Sensor Node Power Control

Use Scenario: Solid-state replacement for mechanical hook switches in VoIP gateway analog front-end (AFE) stages.

IC Role / Device Role / Timing Role: Voltage-controlled switch isolating analog audio path during call setup and teardown sequences.

Use Value: Delivers consistent contact resistance over lifetime, immune to oxidation and bounce-critical for voice quality compliance.

Use Scenario: Controlled power gating for low-power wireless sensor nodes (e.g., LoRaWAN edge devices) during sleep/wake cycles.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZVP3306A	BVDSS = -60 V, RDS(ON) = 3.5 Ω @ VGS = -10 V, ID = -1.2 A	Limited to lower-voltage systems (e.g., 12–24 V industrial controls); unsuitable for -48 V telecom line interface.	Select only where voltage stress is ≤ -60 V and higher current capacity is required.
DMN3026LSD	BVDSS = -30 V, RDS(ON) = 0.045 Ω @ VGS = -10 V, SO-8 package	Optimized for high-current, low-voltage DC-DC and motor drive; incompatible with high-voltage isolation needs.	Use when high efficiency at >1 A and surface-mount thermal relief (SO-8) are prioritized over voltage rating.

Compared with ZVP4424G, ZVP3306A offers higher current but insufficient voltage margin for telecom, while DMN3026LSD delivers ultra-low RDS(ON) at the cost of BVDSS-neither supports -240 V operation, making ZVP4424G uniquely suited for legacy telephony infrastructure and high-reliability HV switching.

FAQ

What is the maximum safe operating voltage for ZVP4424G in continuous DC applications?

The absolute maximum drain-source voltage (BVDSS) is -240 V, tested at ID = -1 mA with VGS = 0 V. For reliable long-term operation, design margins should limit steady-state VDS to ≤ -190 V per datasheet IDSS test condition, especially at elevated temperatures above +85°C where leakage increases.

Can ZVP4424G be driven directly from a 3.3 V microcontroller GPIO?

No-ZVP4424G is a P-channel device requiring negative gate-source voltage for turn-on. A 3.3 V GPIO alone cannot produce the necessary VGS ≤ -0.7 V. It must be paired with an inverting driver (e.g., NPN transistor or dedicated gate driver) referenced to the source potential to generate sufficient negative bias relative to the source.

Is ZVP4424G qualified for automotive applications per AEC-Q101?

No-the datasheet explicitly states that automotive qualification (AEC-Q100/101/200) and PPAP capability require direct engagement with Diodes' automotive team. Standard ZVP4424G is not AEC-Q101 certified and is intended for industrial, telecom, and consumer applications unless specially ordered and documented.

How does the SOT223 package's exposed drain tab affect PCB layout and thermal performance?

The exposed drain tab must be soldered to a minimum 1-inch² 2 oz copper pad to achieve the rated RθJA = 50 °C/W. Thermal vias under the tab improve heat transfer to inner layers; insufficient copper area or missing solder joint causes junction temperature rise exceeding safe limits-even at 50% of rated PD-and risks premature failure under pulsed loads.
