Product details
Overview
ZVN4306ASTOB from Diodes Incorporated is a 60V N-channel enhancement-mode vertical DMOS FET in E-Line (TO-92 compatible) package, rated for 1.1A continuous drain current and 330mΩ RDS(ON) at VGS = 10V, used as a low-side switch in automotive solenoid drivers and DC-DC converter power stages.
For engineers reviewing the ZVN4306ASTOB datasheet, ZVN4306ASTOB pinout, ZVN4306ASTOB application, or ZVN4306ASTOB equivalent, key selection criteria include its 60V BVDSS rating, 150°C max junction temperature, 1.13W practical power dissipation on FR-4 PCB, and AEC-Q101-qualified automotive-grade variants.
Technical Context
This discrete MOSFET operates in enhancement mode with a gate threshold voltage of 1.3–3.0V and delivers 700mS forward transconductance at VDS = 10V and ID = 3A. Its dynamic performance includes 8ns turn-on delay and 30ns turn-off delay under 25V/3A test conditions with 50Ω source impedance.
The device uses vertical DMOS structure for improved ruggedness and thermal stability, with junction-to-ambient thermal resistance of 111°C/W on a 25mm × 25mm × 1.6mm FR-4 board. It supports pulsed drain currents up to 15A and features ±20V gate-source voltage tolerance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel low-voltage power FET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZVN4306A | Same die, identical electrical specs, identical E-Line package; STOB suffix denotes tape-and-reel packaging variant | No functional difference; same automotive and industrial use cases | Select ZVN4306ASTOB for automated SMT placement; ZVN4306A for manual prototyping or box-packaged builds |
| DMN3026LSD-13 | 30V VDSS, 26mΩ RDS(ON) @ 10V, SO-8 package, higher current (6.5A), lower voltage rating | Not suitable for 48V+ systems; better for 5–12V logic-level switching with higher efficiency | Choose only if system voltage ≤30V and board space allows SO-8; not drop-in for ZVN4306ASTOB's 60V requirement |
Compared with ZVN4306A, ZVN4306ASTOB offers identical performance in tape-and-reel form factor, while DMN3026LSD-13 trades voltage headroom for lower RDS(ON) and surface-mount convenience-making it unsuitable for 48V automotive transients but more efficient in low-voltage DC-DC stages.

FAQ
Is ZVN4306ASTOB qualified for automotive applications?
Yes, ZVN4306ASTOB is manufactured in IATF 16949-certified facilities and meets JEDEC high-reliability standards aligned with AEC-Q101. While the base part is not AEC-Q101 certified, Diodes offers Q-suffix automotive-grade variants (e.g., ZVN4306AQ) with full PPAP documentation and change control for under-hood use.
What is the maximum gate drive voltage for ZVN4306ASTOB?
The absolute maximum gate-source voltage (VGS) is ±20V. Operation above ±20V risks permanent gate oxide damage. For reliable switching, drive within 5–10V for optimal RDS(ON) and 3.3V–5V logic compatibility using its 1.3–3.0V VGS(TH) range.
Can ZVN4306ASTOB replace a bipolar transistor in relay driver circuits?
Yes-it provides superior efficiency versus BJTs due to voltage-controlled gate operation and lower saturation losses. With 1.1A continuous current and 15A pulsed rating, it handles typical 12V/24V relay coils (≤1A steady-state), eliminating base-drive current and reducing MCU GPIO loading.
Does ZVN4306ASTOB require a gate resistor in switching applications?
A gate resistor (typically 10–100Ω) is recommended to dampen ringing caused by gate-drain capacitance (Crss = 30pF) and PCB trace inductance. It also limits peak gate current during fast edges, protecting driving GPIOs and improving EMI performance in DC-DC and solenoid drive layouts.
