Diodes Incorporated ZVN4424ASTOA

Overview

ZVN4424ASTOA 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 R_DS(ON) ≤ 6Ω at V_GS = 2.5V. It features low gate threshold (0.8–1.8V), fast switching (t_F ≤ 25ns), and AEC-Q101 qualification for automotive reliability.

For engineers reviewing the ZVN4424ASTOA datasheet, ZVN4424ASTOA pinout, ZVN4424ASTOA application, or ZVN4424ASTOA equivalent, this device serves as a high-voltage, low-current switching element in space-constrained automotive and industrial control circuits where leaded through-hole mounting and thermal robustness are required.

Technical Context

This discrete MOSFET operates in enhancement mode with a vertical DMOS structure optimized for high breakdown voltage and low on-resistance in a compact through-hole package. Its gate threshold voltage range (0.8–1.8V) enables direct interface with low-voltage logic, while its 240V V_DSS rating supports operation across 12V–48V automotive supply rails with margin.

Thermal design is supported by R_θJA = 167°C/W (on FR-4 with 12mm leads) and R_θJL = 71°C/W to solder point, enabling stable operation up to +150°C junction temperature. Switching performance is characterized with 50Ω source impedance and <5ns pulse rise time, confirming suitability for medium-frequency (<1 MHz) digital switching applications.

FAQ

What is the maximum safe operating voltage for ZVN4424ASTOA?

The absolute maximum drain-source voltage (V_DSS) is 240V DC. Operation beyond this rating risks irreversible avalanche breakdown. For reliable long-term use in automotive environments, design with ≥20% margin-e.g., limit V_DS to ≤192V under worst-case transient conditions per ISO 7637-2.

Can ZVN4424ASTOA be driven directly from a 3.3V microcontroller GPIO?

Yes. With V_GS(TH) min = 0.8V and typical R_DS(ON) = 4.3Ω at V_GS = 2.5V, the device fully enhances at 3.3V. Gate charge is low (C_iss ≈ 110–200pF), so standard MCU pins can drive it without external buffers in static or low-frequency PWM applications.

How does the E-Line package compare thermally to standard TO-92?

The E-Line package has identical footprint and lead configuration to TO-92 but uses green molding compound and tighter dimensional tolerances. Its R_θJA = 167°C/W matches typical TO-92 values when mounted per Diodes' recommended pad layout (12mm lead length, single-sided FR-4), making thermal design directly transferable.

Is ZVN4424ASTOA suitable for use in life support equipment?

No. Per Diodes Incorporated's Life Support Notice, this device is explicitly not authorized for use in life support systems without written CEO approval. Its qualification covers AEC-Q101 automotive stress tests-not ISO 13485 or IEC 62304 medical device standards-and no functional safety documentation (e.g., FIT rate, ASIL rating) is provided.
