Product details

Overview

ZVN2110ASTOB from Diodes Incorporated is an N-channel enhancement-mode vertical DMOS FET rated for 100 V drain-source voltage, 4 Ω R_DS(on) at V_GS = 10 V and I_D = 1 A, and 320 mA continuous drain current at 25°C ambient. It serves as a low-power switching device in DC-DC converter feedback paths, LED current regulation, and microcontroller-driven load control circuits.

For engineers reviewing the ZVN2110ASTOB datasheet, ZVN2110ASTOB pinout, ZVN2110ASTOB application, or ZVN2110ASTOB equivalent, key selection criteria include verified 100 V breakdown voltage, gate threshold voltage range (0.8–2.4 V), pulsed drain current capability (6 A), thermal stability up to +150°C junction temperature, and TO-92-compatible lead form factor.

Technical Context

This discrete MOSFET operates in enhancement mode with a vertically structured DMOS cell, enabling higher breakdown voltage and lower on-resistance than planar equivalents in its package class. Its gate threshold voltage (0.8–2.4 V) ensures reliable turn-on with standard 3.3 V or 5 V logic-level drive, while the 75 pF input capacitance supports moderate-speed switching up to ~1 MHz.

The device exhibits stable R_DS(on) over temperature (normalized to 1.0 at 25°C, ≤2.4 at 150°C) and features low reverse transfer capacitance (8 pF), reducing Miller-effect-induced switching delays. Turn-off delay (13 ns) and fall time (13 ns) are characterized with 50 Ω source impedance and sub-5 ns pulse rise time, confirming suitability for digital switching applications requiring predictable timing.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Maximum blocking voltage before avalanche conduction; enables use in 48 V industrial bus and 24 V automotive auxiliary circuits.
R_DS(on)	4 Ω @ V_GS = 10 V, I_D = 1 A - Confirmed static on-resistance under pulsed conditions; determines I²R conduction loss in linear or switching operation.
I_D (cont)	320 mA @ T_amb = 25°C - Continuous safe operating current without heatsinking; defines maximum steady-state load drive capability.
V_GS(th)	0.8–2.4 V @ I_D = 1 mA - Gate voltage range guaranteeing turn-on with 3.3 V MCU GPIO; ensures compatibility with low-voltage logic families.
C_iss	75 pF @ V_DS = 25 V, f = 1 MHz - Input capacitance defining gate drive energy requirement and switching speed limit in resistive-gate drive configurations.
t_d(off)	13 ns @ V_DD ≈ 25 V, I_D = 1 A - Verified turn-off propagation delay under standardized test conditions; critical for timing-critical PWM control loops.
P_tot	700 mW @ T_amb = 25°C - Maximum power dissipation without derating; sets thermal boundary for PCB copper area and ambient airflow requirements.

Pinout & Package

Package: TO-92 (E-Line compatible), through-hole, 3-lead plastic case with standard D-G-S pin assignment.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	High-side current path terminal	Connected to load supply rail; carries full switched current and must be routed with adequate trace width for 6 A pulsed peaks.
Gate (G)	Control electrode	High-impedance input requiring <20 nA leakage handling; sensitive to ESD and requires series resistor (≤100 Ω) for ringing suppression.
Source (S)	Reference node and return path	Typically tied to ground or low-side shunt; forms common reference for gate drive and current sensing in low-side switch configurations.

Key Features

Feature	Design Value
Vertical DMOS structure	Enables 100 V V_DS rating in TO-92 package-unachievable with planar MOSFETs of comparable size and cost.
Low gate threshold spread	V_GS(th) min/max = 0.8/2.4 V ensures consistent turn-on across production lots when driven by 3.3 V logic.
Thermally robust R_DS(on)	Normalized R_DS(on) ≤2.4 at 150°C junction enables stable performance in sealed enclosures or high-ambient environments.
Low Crss/Ciss ratio	Crss/Ciss = 8/75 ≈ 0.11 reduces Miller plateau duration, improving controllability during hard-switching transitions.
Standard TO-92 footprint	Direct drop-in replacement for legacy bipolar transistors (e.g., BC547) in existing through-hole PCB designs without layout change.

Applications

LED Constant-Current Driver

Microcontroller GPIO Load Switch

Use Scenario: Driving single or parallel white LEDs from 5–24 V supply with analog or PWM dimming.

IC Role / Device Role / Timing Role: Low-side current-regulating switch controlled by MCU PWM output or DAC-adjusted gate voltage.

Use Value: 4 Ω R_DS(on) limits conduction loss to <100 mW at 150 mA, enabling passive thermal management on standard FR4.

Use Scenario: Enabling/disabling peripheral modules (sensors, radios, displays) via MCU GPIO pins.

IC Role / Device Role / Timing Role: Logic-level-controlled power gate with fast 13 ns turn-off ensuring clean enable/disable sequencing.

Use Value: 0.8–2.4 V V_GS(th) guarantees full turn-on from 3.3 V MCU outputs without level-shifting circuitry.

DC-DC Converter Feedback Switch

Industrial Signal Conditioning

Use Scenario: Providing programmable current sink in optocoupler-based isolated feedback loop of flyback converters.

IC Role / Device Role / Timing Role: Precision current sink modulated by error amplifier output to regulate output voltage.

Use Value: Stable V_GS(th) and low IDSS (<100 µA at 80 V) minimize feedback drift across temperature and line voltage variations.

Use Scenario: Level-shifting and isolation of 0–10 V analog sensor signals into 3.3 V ADC inputs.

IC Role / Device Role / Timing Role: Voltage-controlled switch enabling signal path selection or gain configuration in analog front-end.

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
ZVN3310A	Higher V_DS (200 V), higher R_DS(on) (10 Ω), same TO-92 package	Better suited for 100 V+ input stages; less efficient at low-voltage loads due to higher conduction loss	Select when system input exceeds 48 V and 4 Ω is not required
2N7002K	Lower V_DS (60 V), lower R_DS(on) (3.5 Ω), SOT-23 package	Requires PCB redesign for surface-mount; unsuitable for >60 V bus but more efficient below 24 V	Select for space-constrained, low-voltage (<36 V) designs where TO-92 is not mandated

Compared with ZVN3310A and 2N7002K, the ZVN2110ASTOB uniquely balances 100 V capability, TO-92 compatibility, and sub-5 Ω on-resistance-making it optimal for legacy through-hole designs needing margin above 48 V without sacrificing efficiency at 24 V operation.

FAQ

Is ZVN2110ASTOB suitable for 3.3 V logic-level gate drive?

Yes. Its gate threshold voltage range (0.8–2.4 V) ensures full enhancement with 3.3 V gate drive, delivering ≥1.5 A on-state current at V_GS = 3.3 V per typical transfer characteristics. No level-shifter is needed for direct connection to 3.3 V MCU GPIOs.

What is the maximum safe operating temperature for continuous use?

The device supports continuous operation up to +150°C junction temperature. At 100% derated ambient (T_amb = 150°C), the maximum allowable continuous drain current drops to ~120 mA based on thermal resistance and P_tot derating curves in the datasheet.

Can ZVN2110ASTOB replace a BC547 BJT in existing circuits?

Yes, in low-side switch configurations. The TO-92 pinout (D-G-S vs. C-B-E) matches BC547's physical layout, and its 320 mA continuous rating exceeds BC547's 100 mA. However, gate drive replaces base current calculation, and no base resistor is needed-simplifying bias network design.

Does ZVN2110ASTOB require a gate resistor for stability?

A small series gate resistor (22–100 Ω) is recommended to dampen parasitic oscillation caused by PCB trace inductance interacting with 75 pF C_iss. This improves switching reliability without significantly increasing turn-on delay, as confirmed by measured t_d(on) = 7 ns under 50 Ω drive conditions.
