Product details

Overview

ZVN4210ASTOB from Zetex Semiconductors (now Diodes Incorporated) is an N-channel enhancement-mode vertical DMOS FET in TO-92 package, rated for 100 V V_DS, 450 mA continuous drain current, and 1.5 Ω R_DS(on) at V_GS = 10 V. It serves as a low-voltage switching element in power management, LED drivers, and load-switching circuits where compact through-hole mounting and moderate current handling are required.

For engineers reviewing the ZVN4210ASTOB datasheet, ZVN4210ASTOB pinout, ZVN4210ASTOB application, or ZVN4210ASTOB equivalent, key selection criteria include verified R_DS(on) ≤ 1.8 Ω at 1.5 A, gate threshold voltage range of 0.8–2.4 V, turn-off delay under 20 ns, and TO-92 thermal derating compliance up to +150 °C junction temperature.

Technical Context

This discrete MOSFET uses vertical DMOS architecture to achieve high breakdown voltage with low on-resistance in a legacy through-hole package. Its enhancement-mode operation requires positive gate bias ≥ 0.8 V to conduct, and it exhibits typical transconductance of 250 mS at V_DS = 25 V and I_D = 1.5 A.

Electrical behavior is characterized by low input capacitance (C_iss = 100 pF), moderate output capacitance (C_oss = 40 pF), and fast switching with t_r = 8 ns and t_f = 30 ns under 25 V/1.5 A test conditions - suitable for DC-DC pre-regulators and PWM-controlled resistive loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	100 V - supports input rails up to 80 V DC with margin for transient spikes
R_DS(on)	1.5 Ω @ V_GS = 10 V, I_D = 1.5 A - enables <1.1 W conduction loss at 1.5 A
I_D cont	450 mA @ T_amb = 25 °C - defines steady-state current limit without heatsink
V_GS(th)	0.8–2.4 V - ensures reliable turn-on with 3.3 V or 5 V logic-level gate drive
t_d(off)	20 ns - limits minimum off-time in PWM applications above ~25 MHz effective frequency
C_iss	100 pF - determines gate drive current requirement (~100 µA avg. at 100 kHz, 10 V swing)
P_tot	700 mW @ T_amb = 25 °C - sets thermal boundary for PCB copper area and ambient airflow

Pinout & Package

Package: TO-92 (E-Line compatible), through-hole, epoxy molded, 3-pin vertical lead frame. Standard pinout orientation with flat side facing viewer: Pin 1 = Gate, Pin 2 = Drain, Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Gate (Pin 1)	Control electrode	Receives voltage bias to modulate channel conductivity; high-impedance input requiring minimal drive current
Drain (Pin 2)	High-side current path	Connected to load supply rail; carries full switched current and withstands 100 V transient stress
Source (Pin 3)	Reference node / return path	Tied to system ground or low-side return; establishes V_GS reference and carries same current as drain

Key Features

Feature	Design Value
Vertical DMOS structure	Enables 100 V breakdown in TO-92 footprint without compromising R_DS(on) density
Logic-level gate threshold	V_GS(th) ≤ 2.4 V allows direct drive from 3.3 V microcontrollers without level-shifting
SPICE model availability	Enables accurate switching loss, thermal, and transient simulation in circuit design phase
Low C_iss/C_oss ratio	C_iss:C_oss ≈ 2.5:1 improves Miller effect immunity during high-dV/dt switching

Applications

LED Constant-Current Driver

Microcontroller-Driven Load Switch

Use Scenario: Driving 1–3 white LEDs from 5–24 V supply with analog dimming via PWM.

IC Role / Device Role / Timing Role: Low-side switch controlling LED cathode return path; operates in linear or saturated switching mode.

Use Value: R_DS(on) ≤ 1.8 Ω limits power dissipation to <1.2 W at 1.5 A, enabling compact PCB layout without heatsink.

Use Scenario: Enabling/disabling peripheral modules (e.g., sensors, radios) under firmware control.

IC Role / Device Role / Timing Role: High-side or low-side power switch activated by GPIO; duty cycle limited by thermal budget.

Use Value: V_GS(th) range ensures turn-on with 3.3 V MCU outputs, and 20 ns t_d(off) supports >10 kHz enable/disable cycling.

DC-DC Pre-Regulator Stage

Overvoltage Protection Clamp

Use Scenario: Simple buck-derived pre-regulator stepping 24 V down to 12 V before LDO stage.

IC Role / Device Role / Timing Role: Synchronous rectifier or pass transistor in non-isolated step-down topology.

Use Value: 100 V V_DS rating provides headroom for 24 V input surges; 250 mS g_fs supports stable closed-loop control.

Use Scenario: Clamping transient overvoltage on 12 V rail using Zener-assisted gate control.

IC Role / Device Role / Timing Role: Voltage-triggered crowbar device activated when rail exceeds safe threshold.

Use Value: Fast 30 ns fall time ensures rapid energy diversion; 150 °C T_j rating sustains brief fault events without latch-up.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel low-power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZVN4208ASTOB	V_DS = 60 V, R_DS(on) = 2.5 Ω @ 10 V - lower voltage rating, higher on-resistance	Suitable only for ≤ 48 V systems; less efficient at 1.5 A due to higher conduction loss	Select when cost sensitivity outweighs voltage margin and efficiency requirements
DMN2004LK-7	SO-8 package, V_DS = 20 V, R_DS(on) = 0.12 Ω @ 4.5 V - surface-mount, lower voltage, much lower R_DS(on)	Requires PCB redesign for SMT; not suitable for >20 V rails but superior for high-current 3.3 V logic-driven loads	Choose for automated assembly and higher efficiency in ≤20 V embedded systems

Compared with ZVN4210ASTOB, ZVN4208ASTOB trades voltage headroom for cost, while DMN2004LK-7 shifts to SMT and lower-voltage optimization - neither is pin-compatible, and both require schematic and layout revision for substitution.

FAQ

Is ZVN4210ASTOB suitable for 3.3 V microcontroller gate drive?

Yes. With V_GS(th) ranging from 0.8 V to 2.4 V and guaranteed R_DS(on) ≤ 1.8 Ω at V_GS = 5 V, it fully turns on using standard 3.3 V or 5 V GPIO outputs. No external level shifter is needed for basic on/off control at ≤450 mA DC load.

What is the maximum safe operating current at 70 °C ambient?

At T_amb = 70 °C, derated continuous drain current is approximately 280 mA, calculated using P_tot = 700 mW and R_DS(on) = 1.5 Ω - resulting in I_D = √(P_tot/R_DS(on)) ≈ 0.68 A theoretical, but thermal resistance (R_θJA ≈ 180 °C/W for TO-92) limits practical I_D to ~280 mA for T_j ≤ 150 °C.

Does ZVN4210ASTOB have built-in ESD protection?

No. The datasheet does not specify integrated ESD protection diodes. External gate protection (e.g., 10 kΩ series resistor + 10 V Zener to source) is recommended when exposed to handling or system-level ESD events per IEC 61000-4-2 Level 2+.

Can ZVN4210ASTOB be used in linear (analog) mode for current regulation?

Yes - its SOA curve supports linear operation up to 100 V × 0.45 A = 45 W at T_amb = 25 °C with adequate heatsinking. However, safe operating area is limited by second breakdown; constant-current LED biasing below 100 mA is robust, but higher-power linear use requires careful thermal design and pulse-width limiting.
