Product details
Overview
ZVN4306AVSTZ from Diodes Incorporated (formerly Zetex) is an N-channel enhancement-mode vertical DMOS FET rated for 60 V VDS, 0.33 Ω RDS(on) at VGS = 10 V / ID = 3 A, and 1.3 A practical continuous drain current; used in automotive solenoid/relay drivers and stepper motor control stages where low conduction loss and repetitive avalanche capability are required.
For engineers reviewing the ZVN4306AVSTZ datasheet, ZVN4306AVSTZ pinout, ZVN4306AVSTZ application, or ZVN4306AVSTZ equivalent, key selection criteria include its TO-92-compatible E-Line package, 25 mJ repetitive avalanche energy rating, 30 ns turn-off delay, and thermal resistance of 150 °C/W (junction-to-ambient) under standard PCB mounting.
Technical Context
This discrete MOSFET operates in enhancement mode with a gate threshold voltage range of 1.3–3 V, enabling direct TTL/CMOS logic-level drive. Its vertical DMOS structure supports unclamped inductive switching up to 1 A repetitive avalanche current at Tj = 25 °C, validated under L = 43 mH, VCC = 12 V test conditions.
The device exhibits 700 mS typical forward transconductance at VDS = 25 V / ID = 3 A and features Ciss = 350 pF, Coss = 140 pF, and Crss = 30 pF at VDS = 25 V, supporting efficient high-frequency switching in DC-DC converters and motor gate-drive circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | 60 V - supports 48 V automotive rail and 24 V industrial bus applications without derating |
| RDS(on) | 0.33 Ω max at VGS = 10 V, ID = 3 A - limits conduction loss to ≤3.0 W at 3 A continuous load |
| ID Continuous | 1.3 A practical - defined for PCB-mounted operation with ≥1 inch² copper area |
| EAR | 25 mJ repetitive avalanche energy - enables robust unclamped inductive turn-off in relay/solenoid loads |
| Switching td(off) | 30 ns - allows >1 MHz PWM operation when paired with low-impedance gate driver |
| Thermal Rth(j-amb) | 150 °C/W - requires thermal relief pads or heatsinking above ~0.5 W dissipation in ambient air |
| Ciss | 350 pF - determines gate charge requirement and driver strength needed for fast transitions |
Pinout & Package
Package: TO-92-compatible E-Line (3-lead plastic through-hole), lead-form compatible with legacy ZVN4306AV footprint; standardized D-G-S terminal assignment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | Main power output path | Connected to load return or high-side switch node; electrically tied to metal tab in TO-92 variant |
| Gate (G) | Control input | High-impedance MOS gate requiring <100 nA leakage handling; sensitive to ESD per ±20 V rating |
| Source (S) | Reference node / current return | Common reference for gate drive and load current sensing; ties to ground or low-side shunt |
Key Features
| Feature | Design Value |
|---|---|
| Repetitive avalanche rated | Validated for 1 A, 25 mJ unclamped inductive switching - eliminates need for external snubbers in relay coils |
| TTL/CMOS-compatible VGS(th) | 1.3–3 V threshold - enables direct interface with 3.3 V/5 V microcontrollers without level-shifting |
| Low Crss/Ciss ratio | 30 pF / 350 pF = 0.086 - reduces Miller effect, improving switching stability in high-dV/dt environments |
| Thermally optimized package | Rth(j-case) = 50 °C/W - allows localized heat transfer to PCB copper when mounted vertically |
Applications
| Automotive Solenoid Driver | Stepper Motor Phase Switch |
|---|---|
Use Scenario: Driving 12 V fuel injector solenoids in engine control units with pulsed 500 ms on-time. IC Role / Device Role / Timing Role: Low-side switch controlling coil current path; handles 1.2 A peak with 30 ns turn-off to minimize back-EMF overshoot. Use Value: 25 mJ avalanche rating absorbs inductive kickback without external clamping diode, reducing BOM count by one component. | Use Scenario: Bipolar stepper motor full-step sequencing in HVAC damper actuators. IC Role / Device Role / Timing Role: One quadrant H-bridge half-bridge element; switches at 20 kHz with 25 ns rise time to limit audible noise. Use Value: 0.33 Ω RDS(on) limits resistive heating to <0.5 W per phase at 1.1 A, enabling compact enclosure design. |

IC Role / Device Role / Timing Role: Final-stage power switch interfacing between isolation barrier and relay coil (1.5 A, 40 Ω). Use Value: TO-92 package allows direct through-hole mounting on control board edge, simplifying layout and creepage distance compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel low-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZVN4306A | Same die, no "STZ" suffix; identical electrical specs and TO-92 package | No functional difference; STZ denotes tape-and-reel packaging per Diodes Inc. internal coding | Select ZVN4306A for tube delivery; ZVN4306AVSTZ for automated SMT placement compatibility |
| DMN2004LK-7 | 20 V VDS, 0.12 Ω RDS(on), SOT-23 package - lower voltage, lower RDS(on), surface-mount only | Not suitable for 48 V systems; limited to ≤12 V logic-level loads due to lower breakdown | Choose only for space-constrained 5–12 V applications where avalanche ruggedness is not required |
Compared with ZVN4306A, the ZVN4306AVSTZ offers identical performance in tape-and-reel form; versus DMN2004LK-7, it trades higher RDS(on) for 60 V rating and proven avalanche robustness-critical for inductive load reliability.

FAQ
What is the maximum safe operating junction temperature for ZVN4306AVSTZ?
The device is rated for Tj = –55 °C to +150 °C. Operation above 125 °C requires active thermal monitoring or derating per the transient thermal impedance curve; sustained 150 °C operation is permitted only with verified PCB copper area ≥1 inch² and ambient ≤70 °C.
Can ZVN4306AVSTZ be driven directly from a 3.3 V microcontroller GPIO?
Yes - its VGS(th) min is 1.3 V, and it delivers 12 A ID(on) at VGS = 10 V. At 3.3 V, RDS(on) rises to ~1.2 Ω (per normalized curves), limiting usable current to ~250 mA continuous; sufficient for low-power relay driving but not motor phases.
Is the TO-92 package of ZVN4306AVSTZ lead-free and RoHS-compliant?
Yes - Diodes Incorporated certifies ZVN4306AVSTZ as RoHS-compliant and lead-free per J-STD-609 Category 1, with matte tin plating and halogen-free molding compound; full compliance documentation is available under part number ZVN4306AVSTZ-13.
Does ZVN4306AVSTZ require a gate resistor for basic switching?
A gate resistor is recommended: 10–47 Ω limits peak gate current and dV/dt-induced oscillation. Without it, ringing may exceed VGS = ±20 V rating during fast transitions; the 350 pF Ciss and 30 pF Crss make it susceptible to Miller-induced false turn-on in high-noise environments.
