Product details

Overview

ZVP2120A from Zetex Semiconductors (now Diodes Incorporated) is a P-channel enhancement-mode vertical DMOS FET designed for low-power switching and linear regulation in high-voltage, low-current applications. It features -200 V drain-source breakdown voltage, 25 Ω R_DS(on) at V_GS = -10 V, -120 mA continuous drain current, and operates across -55 °C to +150 °C. It is commonly used in high-side load switches for industrial sensor interfaces and battery-powered instrumentation.

For engineers reviewing the ZVP2120A datasheet, ZVP2120A pinout, ZVP2120A application, or ZVP2120A equivalent, key selection criteria include verified gate threshold voltage (-1.5 to -3.5 V), guaranteed R_DS(on) ≤ 25 Ω under pulsed conditions, thermal stability of V_GS(th) over temperature, and TO-92-compatible leadform compatibility with legacy through-hole PCB layouts.

Technical Context

This device implements a vertical DMOS structure optimized for high-voltage blocking with low gate charge (Q_g not specified but inferred <10 nC from Crss/Ciss ratios and switching times). Its transconductance of 50 mS at -25 V V_DS and -150 mA supports stable analog gain control in source-follower configurations.

The -200 V BVDSS rating enables direct interface with unregulated 120/230 VAC-derived DC rails after rectification and filtering. Its -100 µA IDSS at -160 V and 125 °C confirms robust leakage control for high-reliability power management stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Rating	-200 V - Supports operation directly from rectified 120/230 VAC supplies without additional voltage clamping.
R_DS(on)	25 Ω @ V_GS = -10 V, I_D = -150 mA - Enables ~3.75 V drop at 150 mA; suitable for low-power high-side switch with <4 V headroom.
I_D Continuous	-120 mA @ T_amb = 25 °C - Limits usable load current in ambient-temperature-constrained PCBs without heatsinking.
V_GS(th)	-1.5 to -3.5 V @ I_D = -1 mA - Ensures reliable turn-on with standard logic-level negative gate drive (e.g., from microcontroller open-drain output).
C_iss	100 pF @ V_DS = -25 V - Low input capacitance reduces gate drive power and speeds up switching in low-frequency (<100 kHz) control loops.
t_d(on)/t_f	7 ns / 15 ns @ V_DD ≈ -25 V, I_D = -150 mA - Fast switching enables efficient PWM dimming or burst-mode regulation in LED/sensor bias circuits.

Pinout & Package

Package: TO-92 compatible (E-Line, 3-lead plastic package, lead spacing per JEDEC TO-92 outline). Pin assignment confirmed via Zetex Issue 2 datasheet diagram and Diodes Incorporated cross-reference documentation.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	High-voltage current sink	Connected to negative rail or load return; withstands -200 V relative to source; primary heat path in linear mode.
Gate (G)	Voltage-controlled switch terminal	Receives negative gate drive; requires ≤ ±20 V swing; high-impedance (I_GSS ≤ 20 nA) minimizes drive current demand.
Source (S)	Reference node and current return	Biased at system ground or positive rail in high-side configuration; defines V_GS reference; carries full load current.

Key Features

Feature	Design Value
Vertical DMOS architecture	Enables -200 V blocking with 25 Ω on-resistance in TO-92 footprint-unachievable with planar MOSFETs at this voltage class.
Low gate leakage	I_GSS ≤ 20 nA at ±20 V ensures minimal gate-drive power loss and stable bias in battery-critical applications.
Thermally stable V_GS(th)	Normalized V_GS(th) drift <±15% from -40 °C to +125 °C supports consistent turn-on behavior across industrial temperature range.
Pulsed current capability	I_DM = -1.2 A (300 µs, ≤2% duty) allows short-circuit protection or surge handling in fault-tolerant sensor power paths.

Applications

Industrial Sensor Biasing

High-Voltage Logic-Level Switch

Use Scenario: Providing regulated negative bias to piezoresistive pressure sensors in 24 V industrial PLC I/O modules.

IC Role / Device Role / Timing Role: High-side P-channel switch controlling sensor supply rail; operates in linear region for precise current limiting.

Use Value: -200 V rating prevents breakdown during transient surges on 24 V bus; 25 Ω R_DS(on) enables accurate 100 µA–1 mA bias current setting with <2.5 V drop.

Use Scenario: Enabling/disabling isolated 48 V telecom subsystems using microcontroller GPIO with open-drain output.

IC Role / Device Role / Timing Role: Level-shifting high-side switch translating 0/3.3 V logic to -48 V load control signal.

Use Value: -3.5 V max V_GS(th) ensures full enhancement with 3.3 V GPIO pull-down; TO-92 form factor simplifies manual repair and prototyping.

Low-Power AC/DC Auxiliary Supply

Thermocouple Cold-Junction Compensation

Use Scenario: Regulating auxiliary -12 V rail derived from rectified mains in offline SMPS feedback controllers.

IC Role / Device Role / Timing Role: Linear pass element in shunt-regulated auxiliary supply; dissipates <700 mW at full load.

Use Value: 700 mW P_tot and -55 to +150 °C T_j range support continuous operation in enclosed power enclosures without forced air cooling.

Use Scenario: Precision current source for thermocouple cold-junction compensation circuit in data acquisition front-ends.

IC Role / Device Role / Timing Role: Constant-current sink delivering stable -100 µA to PT1000 reference resistor.

Use Value: -100 µA IDSS at -160 V/125 °C ensures <0.1% current error drift over temperature; low C_iss avoids noise coupling into µV-level analog signals.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel high-voltage switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZVP2110A	V_DS = -100 V, R_DS(on) = 100 Ω - Lower voltage rating, higher on-resistance.	Not suitable for >100 V systems; acceptable only where lower blocking voltage and higher dropout are tolerable.	Select only when design operates below 80 V and space constraints favor identical TO-92 footprint.
DMN2011UFG-7	V_DS = -20 V, R_DS(on) = 0.12 Ω - 10× lower voltage, 200× lower R_DS(on), SOT-23 package.	Requires level-shifting for high-side use; unsuitable for direct -200 V connection; incompatible pinout.	Choose only for low-voltage, high-current digital switching where TO-92 mounting is not required.

Compared with ZVP2120A, ZVP2110A sacrifices voltage headroom and conduction efficiency for identical packaging, while DMN2011UFG-7 trades off voltage capability entirely for ultra-low R_DS(on) and surface-mount integration-neither serves as a drop-in replacement.

FAQ

Is ZVP2120A suitable for use in high-side switch configurations with 120 VAC-derived DC rails?

Yes. With a -200 V V_DS rating and -100 µA IDSS at -160 V and 125 °C, ZVP2120A safely handles peak rectified voltages from 120 VAC (≈-170 V) and transient overvoltages common in industrial environments. Its TO-92 package must be mounted with adequate creepage clearance per IPC-2221B.

What is the maximum safe continuous power dissipation in free-air conditions?

The absolute maximum P_tot is 700 mW at T_amb = 25 °C. Derating is required above 25 °C at 10 mW/°C. At 75 °C ambient, maximum continuous dissipation drops to 200 mW. PCB copper area and airflow significantly affect real-world thermal performance.

Can ZVP2120A be driven directly from a 3.3 V microcontroller GPIO pin?

No-direct connection is unsafe. The gate requires negative voltage relative to source for turn-on. A level-shifting circuit (e.g., NPN inverter or dedicated gate driver) is required to generate -3.5 to -10 V gate drive from a 0/3.3 V logic signal. Open-drain GPIO with pull-up to negative rail is a common implementation.

Does ZVP2120A have built-in ESD protection?

No. The datasheet does not specify on-chip ESD protection diodes. External protection (e.g., series resistor + TVS to ground on gate) is recommended for handling during PCB assembly and in-system operation where static discharge risk exists, especially given its sensitive gate oxide.
