Product details

Overview

ZVN4424ASTOB from Diodes Incorporated is a 240V N-channel enhancement-mode vertical DMOSFET in E-Line (TO-92 compatible) package, rated for 260mA continuous drain current, 750mW power dissipation, and featuring R_DS(ON) ≤ 6Ω at V_GS = 2.5V and low 1.3V typical gate threshold voltage. It is AEC-Q101 qualified and used in automotive body electronics, LED driver switching stages, and low-power AC/DC auxiliary supplies.

For engineers reviewing the ZVN4424ASTOB datasheet, ZVN4424ASTOB pinout, ZVN4424ASTOB application, or ZVN4424ASTOB equivalent, key selection criteria include its 240V BVDSS rating, sub-2V VGS(TH), TO-92-compatible thermal resistance (RθJA = 167°C/W), and AEC-Q101 qualification for under-hood automotive use.

Technical Context

This discrete MOSFET operates in enhancement mode with vertical DMOS architecture, enabling high-voltage blocking (240V) while maintaining low gate drive requirements. Its 0.8–1.8V V_GS(TH) range and 4–5.5Ω R_DS(ON) at 10V allow direct interfacing with 3.3V and 5V logic controllers without level-shifting.

Thermal design relies on its 71°C/W junction-to-lead resistance and 167°C/W junction-to-ambient rating under standard FR-4 mounting. Switching performance is characterized by 2.5–5ns turn-on delay and 16–25ns fall time at V_DD = 50V, supporting efficient operation up to several hundred kHz in flyback and linear regulator control circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
BVDSS	240 V - Maximum drain-source blocking voltage before avalanche conduction begins
RDS(ON)	4–5.5 Ω @ VGS = 10V - On-resistance determines conduction loss and junction temperature rise at 260mA load
VGS(TH)	0.8–1.8 V - Gate threshold enables direct drive from low-voltage microcontrollers and logic outputs
ID (Continuous)	260 mA - Maximum steady-state drain current sustainable with proper PCB heatsinking
PD	750 mW - Power dissipation limit under still-air conditions with minimum pad layout
tF / tR	16–25 ns / 5–8 ns - Fast switching times reduce transition losses in PWM-controlled loads
RθJA	167 °C/W - Thermal resistance defines required board copper area for safe operation at ambient +85°C

Pinout & Package

E-Line (TO-92 compatible) plastic package with matte tin-plated leads; 0.159g weight; UL 94V-0 flammability rating; flat-face marking orientation with G-D-S terminal layout.

Green packaging	Halogen- and antimony-free compound meets automotive environmental compliance standards (Br+Cl <1500ppm, Sb <1000ppm)
Fast switching	Sub-10ns rise/fall times minimize energy loss during transitions in PWM dimming and power sequencing
TO-92 compatibility	Allows drop-in replacement in legacy through-hole designs using standard insertion and wave-solder tooling

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
ZVN4424A	Same die, straight-lead E-Line variant; identical electrical specs and AEC-Q101 qualification	Loose packaging; suited for manual assembly or low-volume prototyping	Select when lead configuration matches existing through-hole footprint and tape-and-reel not required
DMN24H3D5L	30V-rated, 5.5mΩ R_DS(ON), SOT-23 package; higher current (3.5A), lower voltage capability	Surface-mount only; unsuitable for 240V applications but better for high-efficiency 5V/12V logic-level switching	Choose only for low-voltage, high-current DC-DC or load-switching where 240V rating is unnecessary

Compared with ZVN4424ASTOB, ZVN4424A offers identical performance in straight-lead form for manual assembly, while DMN24H3D5L trades 240V capability for much lower R_DS(ON) and SMT compatibility-making it viable only in sub-30V systems where voltage margin is not required.

FAQ

What is the maximum operating temperature for ZVN4424ASTOB?

The ZVN4424ASTOB has an operating junction temperature range of –55°C to +150°C. Its thermal resistance (RθJA = 167°C/W) means that at 260mA and 750mW dissipation, junction temperature rise above ambient is approximately 125°C-so ambient must be kept below +25°C for safe operation at full rating without heatsinking.

Is ZVN4424ASTOB pin-compatible with standard TO-92 devices?

Yes-ZVN4424ASTOB uses the E-Line package, which is mechanically and dimensionally compatible with TO-92. Pinout is G-D-S in flat-face view, matching common TO-92 layouts. Lead pitch (2.54mm) and body dimensions (4.37–4.77mm D × 3.61–4.01mm E) conform to JEDEC TO-92 standards for automated insertion and soldering.

Does ZVN4424ASTOB require a gate resistor in typical switching applications?

A gate resistor (typically 10–100Ω) is recommended to dampen ringing caused by gate-drain capacitance (Crss = 3.5–15pF) and PCB trace inductance. While not strictly required for DC switching, it improves EMI performance and prevents unintended oscillation during fast edge transitions from microcontroller GPIOs.

Can ZVN4424ASTOB be used in linear regulator applications?

Yes-it is rated for linear operation with 750mW power dissipation and 167°C/W thermal resistance. When used as a pass element, ensure junction temperature stays below 150°C by limiting V_DS × I_D product and providing adequate copper area; derate power by 50% above +70°C ambient per standard thermal guidelines.
