Product details

Overview

ZVNL120ASTOA from Zetex (now Diodes Incorporated) is an N-channel enhancement-mode vertical DMOS FET rated for 200 V drain-source voltage, 10 Ω R_DS(on) at V_GS = 5 V / I_D = 250 mA, and 180 mA continuous drain current at 25°C ambient; it serves as a low-threshold, medium-voltage switching device in telephone handset ringer and alert circuitry.

For engineers reviewing the ZVNL120ASTOA datasheet, ZVNL120ASTOA pinout, ZVNL120ASTOA application, or ZVNL120ASTOA equivalent, key selection criteria include verified V_GS(th) range (0.5–1.5 V), pulsed current capability (2 A), thermal derating behavior up to +150°C junction temperature, and TO-92-compatible leadform compatibility with legacy telephony designs.

Technical Context

This discrete MOSFET employs vertical DMOS construction to achieve high breakdown voltage with low on-resistance in a through-hole TO-92 package. Its low gate threshold enables direct drive from 3.3 V or 5 V logic without level-shifting, and its 85 pF input capacitance supports fast switching with minimal gate drive power.

Switching performance is characterized by 8 ns turn-on delay, 8 ns rise time, 20 ns turn-off delay, and 12 ns fall time under standardized 25 V/250 mA test conditions with 50 Ω source impedance - confirming suitability for audio-frequency switching in telecom signal path control.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	200 V - supports operation across full telephone line ringing voltage (≈100 V peak AC + transients)
R_DS(on)	10 Ω at V_GS = 5 V, I_D = 250 mA - delivers ≤2.5 V drop at 250 mA, enabling efficient load switching
V_GS(th)	0.5–1.5 V - ensures reliable turn-on from 3.3 V microcontrollers or analog comparators
I_D (continuous)	180 mA at T_amb = 25°C - sufficient for driving piezoelectric ringers or LED indicators
P_tot	700 mW at T_amb = 25°C - requires heatsinking or derating above 70°C ambient
C_iss	85 pF - limits gate drive current requirement to <1 mA for 100 kHz switching
t_d(on)/t_f	8 ns / 12 ns - supports clean edge transitions in audio-band pulse generation

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	High-side switched output node	Connected to load (e.g., ringer coil) and high-voltage supply rail; carries full switched current
Gate (G)	Control input terminal	Receives logic-level voltage; low 100 nA leakage allows simple pull-down resistor biasing
Source (S)	Reference return path	Common ground reference for gate drive and load return; tied to system GND in low-side configuration

Key Features

Feature	Design Value
Low V_GS(th)	0.5–1.5 V enables direct interface with 3.3 V/5 V logic without gate driver ICs
Vertical DMOS structure	Delivers 200 V BVDSS with 10 Ω R_DS(on) in compact TO-92 footprint
Fast switching	8 ns t_d(on), 12 ns t_f supports clean audio-frequency pulse generation
Thermal robustness	Rated for T_j = –55°C to +150°C - survives reflow and long-term telecom environmental stress
TO-92 compatibility	Drop-in replacement for legacy ZVNxxx series in existing handsets and PCB layouts

Applications

Telephone Ringer Driver

LED Alert Switch

Use Scenario: Driving piezoelectric or electromagnetic ringer elements during incoming call alerts in cordless/corded handsets.

IC Role / Device Role / Timing Role: High-voltage switch controlling AC ringing waveform amplitude and duration.

Use Value: 200 V rating withstands 100 V RMS line transients; 10 Ω R_DS(on) minimizes power loss during 20–40 Hz burst switching.

Use Scenario: Enabling/disabling status LEDs in battery-powered handset interfaces.

IC Role / Device Role / Timing Role: Low-threshold load switch activated by baseband processor GPIO.

Use Value: 0.5 V V_GS(th) ensures turn-on at 1.8 V logic levels; 180 mA rating supports multi-LED strings.

Battery Protection Switch

Audio Path Mute Control

Use Scenario: Isolating backup battery from charging circuitry during fault conditions in dual-power handsets.

IC Role / Device Role / Timing Role: Reverse-polarity and overvoltage protection switch in power path.

Use Value: ±20 V V_GS rating accommodates transient clamping circuits; 100 µA I_DSS ensures low standby leakage.

Use Scenario: Muting speaker or microphone paths during call setup or noise suppression cycles.

IC Role / Device Role / Timing Role: Signal-path shunt or series switch in analog audio front-end.

Use Value: 200 mS g_fs provides linear gain control region; low C_oss (20 pF) avoids high-frequency signal attenuation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZVN2110A	V_DS = 60 V, R_DS(on) = 5 Ω, V_GS(th) = 1.0–2.5 V	Limited to lower-voltage handset subsystems (e.g., keypad backlight); not suitable for ringing circuits	Select when 60 V rating suffices and lower R_DS(on) is prioritized over high-voltage tolerance
DMN2004LK-7	V_DS = 20 V, R_DS(on) = 3.5 Ω, SOT-23 package, V_GS(th) = 0.5–1.2 V	SMT-only, unsuitable for through-hole legacy boards; optimized for space-constrained digital I/O switching	Choose for new PCB designs requiring SMT miniaturization and 3.3 V logic compatibility

Compared with ZVNL120ASTOA, ZVN2110A trades voltage headroom for lower conduction loss in sub-60 V rails, while DMN2004LK-7 sacrifices package compatibility and voltage rating for footprint reduction and enhanced low-V_GS consistency in modern digital systems.

FAQ

What is the maximum safe operating voltage for ZVNL120ASTOA in continuous DC mode?

The absolute maximum drain-source voltage is 200 V DC, verified per JEDEC JESD74A. Operation at this rating requires strict adherence to thermal limits: P_tot must remain ≤700 mW at 25°C ambient, with linear derating to zero at 150°C junction temperature. Sustained 200 V operation is only viable at I_D < 3.5 mA due to R_DS(on) self-heating.

Can ZVNL120ASTOA be driven directly from a 1.8 V GPIO pin?

Yes - its guaranteed V_GS(th) minimum of 0.5 V ensures turn-on at 1.8 V, but R_DS(on) will be higher than specified (≈15–20 Ω) due to reduced gate overdrive. For full 10 Ω performance, ≥3 V gate drive is recommended; use a small-signal BJT buffer if only 1.8 V is available.

Is ZVNL120ASTOA RoHS compliant and halogen-free?

Yes - Diodes Incorporated confirms ZVNL120ASTOA meets RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The TO-92 package uses matte tin-plated leads and halogen-free epoxy molding compound, with full compliance documentation available under Diodes' part number ZVNL120ASTOA-TP.

Does ZVNL120ASTOA require external gate protection against ESD?

No external gate protection is required for typical handset environments: the device has built-in gate oxide protection with ±20 V V_GS rating and 100 nA IGSS at ±20 V. However, in automated assembly or handling with >3 kV HBM risk, a 10 kΩ series gate resistor is recommended to limit transient current during board insertion.
