Diodes Incorporated ZVN4206ASTOB

Overview

ZVN4206ASTOB from Diodes Incorporated is an N-channel enhancement-mode vertical DMOS FET in TO-92 package, rated for 60 V V_DS, 600 mA continuous drain current, and 1 Ω R_DS(on) at V_GS = 10 V. It operates across –55°C to +150°C junction temperature and delivers 3 A pulsed drain current, commonly used in low-power DC-DC converter switching stages and LED driver load switches.

For engineers reviewing the ZVN4206ASTOB datasheet, ZVN4206ASTOB pinout, ZVN4206ASTOB application, or ZVN4206ASTOB equivalent, key selection criteria include verified R_DS(on) ≤ 1.5 Ω at 500 mA/5 V drive, gate threshold voltage range (1.3–3 V), and thermal performance under 0.7 W P_tot at 25°C ambient.

Technical Context

This discrete MOSFET uses vertical DMOS construction for improved conduction efficiency and thermal stability in through-hole power switching. Its gate threshold voltage (1.3–3 V) enables direct interface with 3.3 V and 5 V logic controllers without level-shifting.

Switching performance is characterized by 8 ns turn-on delay, 12 ns rise time, 12 ns turn-off delay, and 15 ns fall time under 25 V V_DD, 1.5 A I_D, and 50 Ω source impedance - confirming suitability for medium-frequency (<1 MHz) PWM control in compact power management circuits.

FAQ

What is the maximum safe gate-source voltage for ZVN4206ASTOB?

The absolute maximum V_GS is ±20 V. Operation beyond this risks irreversible gate oxide damage. For reliable long-term use, keep V_GS within –12 V to +12 V during switching transients, especially in inductive load circuits where ringing may occur.

Can ZVN4206ASTOB be used in a high-side switch configuration?

Yes - its 60 V V_DS rating and 3 V V_GS(th) max allow high-side use with appropriate gate drive. However, a dedicated high-side driver or charge pump is required to maintain V_GS ≥ 10 V when source rises above 5 V, as the TO-92 package lacks integrated bootstrap capability.

How does temperature affect R_DS(on) in ZVN4206ASTOB?

R_DS(on) increases with junction temperature: normalized R_DS(on) reaches ~2.2× its 25°C value at 150°C. At 100°C, it is ~1.6× nominal. Designers must derate I_D accordingly - e.g., limit continuous current to ~400 mA at 100°C ambient with minimal copper area.

Is ZVN4206ASTOB RoHS compliant and halogen-free?

Yes - ZVN4206ASTOB meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The "STOB" suffix denotes tape-and-reel packaging with lead-free (Pb-free) terminations and matte tin plating, fully compatible with standard reflow profiles.
