Product details

Overview

ZVP3306ASTOB from Zetex Semiconductors (now Diodes Incorporated) is a P-channel enhancement-mode vertical DMOS FET in TO-92 package, rated for -60 V V_DS, 14 Ω R_DS(on) at V_GS = -10 V, and -160 mA continuous drain current; used in low-power DC-DC converter load switches and battery protection circuits.

For engineers reviewing the ZVP3306ASTOB datasheet, ZVP3306ASTOB pinout, ZVP3306ASTOB application, or ZVP3306ASTOB equivalent, key selection criteria include verified gate threshold voltage (-1.5 to -3.5 V), pulsed drain capability (-1.6 A), thermal stability up to +150 °C junction temperature, and TO-92 mechanical compatibility with legacy through-hole designs.

Technical Context

This discrete MOSFET operates in enhancement mode with negative gate control, requiring V_GS ≤ -1.5 V to initiate conduction. Its vertical DMOS structure delivers low R_DS(on) while maintaining robust avalanche ruggedness per design test conditions.

Switching performance is characterized by matched 8 ns turn-on/turn-off delay and rise/fall times under V_DD ≈ -18 V, I_D = -200 mA, and 50 Ω source impedance - confirming suitability for medium-speed power control below 100 kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-60 V: Maximum reverse drain-source blocking voltage before breakdown
R_DS(on)	14 Ω @ V_GS = -10 V, I_D = -200 mA: On-resistance determines conduction loss in linear or saturated switching
V_GS(th)	-1.5 to -3.5 V @ I_D = -1 mA: Gate threshold range defines minimum drive voltage needed for reliable turn-on
I_D (cont)	-160 mA @ T_amb = 25 °C: Continuous current rating limited by 625 mW package power dissipation
C_iss	50 pF @ V_DS = -18 V, V_GS = 0 V, f = 1 MHz: Input capacitance affects gate drive energy and switching speed
g_fs	60 mS @ V_DS = -18 V, I_D = -200 mA: Transconductance quantifies gain of gate voltage to drain current

Pinout & Package

TO-92 package (E-Line compatible), 3-lead through-hole plastic case with standard D-G-S pin assignment (viewed from flat side, leads down: left = Drain, center = Gate, right = Source).

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	High-side current return path	Connected to negative rail or load return; withstands -60 V reverse bias
Gate (G)	Control electrode	Receives negative voltage relative to source to modulate channel conductivity
Source (S)	Reference node for gate drive	Biased at system ground or positive rail; defines V_GS reference point

Key Features

Feature	Design Value
P-channel enhancement mode	Enables high-side switching without level-shifting circuitry when source is tied to positive supply
Vertical DMOS construction	Provides higher cell density and lower R_DS(on) than planar P-MOSFETs in same package
150 °C maximum junction temperature	Supports operation in sealed enclosures or elevated ambient environments without derating
Matched 8 ns switching times	Ensures predictable timing margins in synchronous rectifier or PWM-controlled loads

Applications

IC Role / Device Role / Timing Role: High-side P-FET switch controlled by protection IC to disconnect load when fault detected.

Use Value: 14 Ω R_DS(on) limits voltage drop to <100 mV at 7 mA sleep current, preserving battery shelf life.

Use Scenario: Synchronous rectification in buck converter output stage operating at 3.3 V or 5 V input.

IC Role / Device Role / Timing Role: Low-side switch replacing Schottky diode to reduce conduction loss.

Use Value: 60 mW power dissipation at -160 mA enables self-cooled operation without heatsinking.

Use Scenario: Constant-current LED driver for indicator or status lighting in industrial panels.

IC Role / Device Role / Timing Role: Linear-mode current regulator using gate voltage feedback to set I_D.

Use Value: -3.5 V V_GS(th) upper limit ensures turn-on with 3.3 V MCU outputs via simple resistor divider.

Use Scenario: Driving small solenoids or relays from 5 V microcontroller I/O pins.

IC Role / Device Role / Timing Role: Level-translated switch interfacing logic-level signals to higher-voltage loads.

Use Value: TO-92 footprint allows direct replacement of obsolete 2N7002-type devices in existing PCB layouts.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZVP2106A	V_DS = -60 V, R_DS(on) = 10 Ω @ V_GS = -10 V, I_D = -200 mA	Lower on-resistance but higher gate charge (Q_g = 12 nC vs 8 nC)	Preferred where conduction loss dominates; requires stronger gate drive.
DMG2305U	V_DS = -20 V, R_DS(on) = 45 mΩ @ V_GS = -4.5 V, SOT-23 package	Higher current rating (-4.2 A), but lower voltage rating and surface-mount only	Selected for space-constrained 3.3 V systems; not suitable for -48 V backup rails.

Compared with ZVP3306ASTOB, ZVP2106A improves efficiency in low-duty-cycle switching but increases gate drive demand, while DMG2305U enables miniaturization at the cost of voltage headroom and through-hole compatibility.

FAQ

What is the maximum safe gate-source voltage for ZVP3306ASTOB?

The absolute maximum V_GS is ±20 V. Exceeding this risks permanent gate oxide damage. In practice, gate drive should be limited to -10 V for full enhancement and -5 V for partial turn-on, as V_GS(th) spans -1.5 to -3.5 V. A series resistor (e.g., 10 kΩ) is recommended to limit transient current during switching.

Can ZVP3306ASTOB be used in linear (ohmic) mode for current regulation?

Yes - its specified R_DS(on) and transconductance (g_fs = 60 mS) support stable linear operation. At V_DS = -10 V and V_GS = -4.5 V, it delivers ~80 mA with <5% variation over temperature. Power dissipation must remain ≤625 mW, limiting usable linear range to I_D ≤ 62 mA at V_DS = -10 V.

Is ZVP3306ASTOB RoHS compliant and halogen-free?

Yes - as manufactured by Diodes Incorporated post-acquisition, ZVP3306ASTOB meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The TO-92 package uses matte tin-plated leads and lead-free molding compound, with full compliance documentation available under Diodes Inc. part number ZVP3306ASTOBQ.

How does temperature affect R_DS(on) and V_GS(th) in ZVP3306ASTOB?

Per typical characteristics, R_DS(on) increases ~1.8× from -40 °C to +150 °C, while V_GS(th) decreases ~0.4 V over the same range. At 125 °C, R_DS(on) rises to ~25 Ω, requiring gate overdrive (e.g., V_GS = -12 V) to maintain low conduction loss in high-temp applications.
